Hagia Sophia
Hagia Sophia (from the Greek: Ἁγία Σοφία, "Holy Wisdom"; Latin: Sancta Sophia or Sancta Sapientia; Turkish: Ayasofya) is a former Orthodox patriarchal basilica, later a mosque, and now a museum in Istanbul, Turkey. From the date of its dedication in 360 until 1453, it served as the Greek Patriarchal cathedral of Constantinople, except between 1204 and 1261, when it was converted to a Roman Catholic cathedral under the Latin Patriarch of Constantinople of the Western Crusader established Latin Empire. The building was a mosque from 29 May 1453 until 1931, when it was secularized. It was opened as a museum on 1 February 1935.
The Church was dedicated to the Logos, the second person of the Holy Trinity, its dedication feast taking place on 25 December, the anniversary of the Birth of the incarnation of the Logos in Christ. Although it is sometimes referred to as Sancta Sophia (as though it were named after Saint Sophia), sophia is the phonetic spelling in Latin of the Greek word for wisdom – the full name in Greek being Ναός τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, "Church of the Holy Wisdom of God".
Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture." It was the largest cathedral in the world for nearly a thousand years, until Seville Cathedral was completed in 1520. The current building was originally constructed as a church between 532 and 537 on the orders of the Byzantine Emperor Justinian and was the third Church of the Holy Wisdom to occupy the site, the previous two having both been destroyed by rioters. It was designed by the Greek scientists Isidore of Miletus, a physicist, and Anthemius of Tralles, a mathematician.
The church contained a large collection of holy relics and featured, among other things, a 49-foot (15 m) silver iconostasis. It was the seat of the Patriarch of Constantinople and the religious focal point of the Eastern Orthodox Church for nearly one thousand years. It is the church in which Cardinal Humbert in 1054 excommunicated Michael I Cerularius – which is commonly considered the start of the Great Schism.
In 1453, Constantinople was conquered by the Ottoman Turks under Sultan Mehmed II, who subsequently ordered the building converted into a mosque. The bells, altar, iconostasis, and sacrificial vessels were removed and many of the mosaics were plastered over. Islamic features – such as the mihrab, minbar, and four minarets – were added while in the possession of the Ottomans. It remained a mosque until 1931 when it was closed to the public for four years. It was re-opened in 1935 as a museum by the Republic of Turkey.
For almost 500 years the principal mosque of Istanbul, Hagia Sophia served as a model for many other Ottoman mosques, such as the Sultan Ahmed Mosque (Blue Mosque of Istanbul), the Şehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque and the Kılıç Ali Paşa Mosque.
History
First church
The first church was known as the Μεγάλη Ἐκκλησία (Megálē Ekklēsíā, "Great Church"), or in Latin "Magna Ecclesia", because of its larger dimensions in comparison to the contemporary churches in the City. Inaugurated on 15 February 360 (during the reign of Constantius II) by the Arian bishop Eudoxius of Antioch, it was built next to the area where the imperial palace was being developed. The nearby Hagia Eirene ("Holy Peace") church was completed earlier and served as cathedral until the Hagia Sophia was completed. Both churches acted together as the principal churches of the Byzantine Empire.
Writing in 440, Socrates of Constantinople claimed that the church was built by Constantius II, who was working on it in 346. A tradition which is not older than the 7th – 8th century, reports that the edifice was built by Constantine the Great. Zonaras reconciles the two opinions, writing that Constantius had repaired the edifice consecrated by Eusebius of Nicomedia, after it had collapsed. Since Eusebius was bishop of Constantinople from 339 to 341, and Constantine died in 337, it seems possible that the first church was erected by the latter. The edifice was built as a traditional Latin colonnaded basilica with galleries and a wooden roof. It was preceded by an atrium. It was claimed to be one of the world's most outstanding monuments at the time.
The Patriarch of Constantinople John Chrysostom came into a conflict with Empress Aelia Eudoxia, wife of the emperor Arcadius, and was sent into exile on 20 June 404. During the subsequent riots, this first church was largely burned down. Nothing remains of the first church today.
Second church

Marble blocks from the second church
A second church was ordered by Theodosius II, who inaugurated it on 10 October 415. The basilica with a wooden roof was built by architect Rufinus. A fire started during the tumult of the Nika Revolt and burned the second Hagia Sophia to the ground on 13–14 January 532
Several marble blocks from the second church survive to the present; among them are reliefs depicting 12 lambs representing the 12 apostles. Originally part of a monumental front entrance, they now reside in an excavation pit adjacent to the museum's entrance. Discovered in 1935 beneath the western courtyard by A. M. Schneider, further digging was forsaken for fear of impinging on the integrity of the Hagia Sophia.
Third church (current structure)
On 23 February 532, only a few days after the destruction of the second basilica, Emperor Justinian I elected to build a third and entirely different basilica, larger and more majestic than its predecessors.
Construction of church depicted in codex Manasses Chronicle
Justinian chose physicist Isidore of Miletus and mathematician Anthemius of Tralles as architects; Anthemius, however, died within the first year of the endeavor. The construction is described in the Byzantine historian Procopius' On Buildings (Peri ktismatōn, Latin: De aedificiis). The emperor had material brought from all over the empire – such as Hellenistic columns from the Temple of Artemis at Ephesus, large stones from quarries in porphyry from Egypt, green marble from Thessaly, black stone from the Bosporus region, and yellow stone from Syria. More than ten thousand people were employed. This new church was contemporaneously recognized as a major work of architecture. The theories of Heron of Alexandria may have been utilized to address the challenges presented by building such an expansive dome over so large a space. The emperor, together with the patriarch Eutychius, inaugurated the new basilica on 27 December 537 with much pomp. The mosaics inside the church were, however, only completed under the reign of Emperor Justin II (565–578).
Hagia Sophia was the seat of the Orthodox patriarch of Constantinople and a principal setting for Byzantine imperial ceremonies, such as coronations. The basilica also offered asylum to wrongdoers.
Earthquakes in August 553 and on 14 December 557 caused cracks in the main dome and eastern half-dome. The main dome collapsed completely during a subsequent earthquake on 7 May 558, destroying the ambon, altar, and ciborium. The crash was due mainly to the too high bearing load and to the enormous shearing load of the dome, which was too flat. These caused the deformation of the piers which sustained the dome. The emperor ordered an immediate restoration. He entrusted it to Isidorus the Younger, nephew of Isidore of Miletus, who used lighter materials and elevated the dome by "30 feet" (about 6.25 metres (20.5 ft)) – giving the building its current interior height of 55.6 metres (182 ft). Moreover, Isidorus changed the dome type, erecting a ribbed dome with pendentives, whose diameter lay between 32.7 and 33.5 m. This reconstruction, giving the church its present 6th-century form, was completed in 562. The Byzantine poet Paul the Silentiary composed a long epic poem (still extant), known as Ekphrasis, for the rededication of the basilica presided over by Patriarch Eutychius on 23 December 562.
In 726, the emperor Leo the Isaurian issued a series of edicts against the veneration of images, ordering the army to destroy all icons – ushering in the period of Byzantine iconoclasm. At that time, all religious pictures and statues were removed from the Hagia Sophia. After a brief reprieve under Empress Irene (797–802), the iconoclasts made a comeback. Emperor Theophilus (829–842) was strongly influenced by Islamic art, which forbids graven images. He had a two-winged bronze door with his monograms installed at the southern entrance of the church.
The basilica suffered damage, first in a great fire in 859, and again in an earthquake on 8 January 869, that made a half-dome collapse. Emperor Basil I ordered the church repaired.
After the great earthquake of 25 October 989, which collapsed the Western dome arch, the Byzantine emperor Basil II asked for the Armenian architect Trdat (Armenian: Տրդատ ճարտարապետ; Latin: Tiridates), creator of the great churches of Ani and Argina, to direct the repairs. He erected again and reinforced the fallen dome arch, and rebuilt the west side of the dome with 15 dome ribs. The extent of the damage required six years of repair and reconstruction; the church was re-opened on 13 May 994. At the end of the reconstruction, the church's decorations were renovated, including the additions of paintings of four immense cherubs, a new depiction of Christ on the dome, and on the apse a new depiction of the Virgin Mary holding Jesus between the apostles Peter and Paul. On the great side arches were painted the prophets and the teachers of the church.
In his book De caerimoniis aulae Byzantinae ("Book of Ceremonies"), Emperor Constantine VII (913–919) wrote a detailed account of the ceremonies held in the Hagia Sophia by the emperor and the patriarch.

Upon the capture of Constantinople during the Fourth Crusade, the church was ransacked and desecrated by the Latin Christians. The Byzantine historian Niketas Choniates described the capture of Constantinople; many reputed relics from the church – such as a stone from the tomb of Jesus, the Virgin Mary's milk, the shroud of Jesus, and bones of several saints – were sent to churches in the West and can be seen there now in various museums. During the Latin occupation of Constantinople (1204–1261) the church became a Roman Catholic cathedral. Baldwin I of Constantinople was crowned emperor on 16 May 1204 in Hagia Sophia, at a ceremony which closely followed Byzantine practices. Enrico Dandolo, the Doge of Venice who commanded the sack and invasion of the city by the Latin Crusaders in 1204, is buried inside the church. The tomb inscription carrying his name, which has become a part of the floor decoration, was spat upon by many of the angry Byzantines who recaptured Constantinople in 1261. However, restoration led by the brothers Gaspare and Giuseppe Fossati during the period 1847–1849 cast doubt upon the authenticity of the doge's grave; it is more likely a symbolic memorial rather than burial site.
After the recapture in 1261 by the Byzantines, the church was in a dilapidated state. In 1317, emperor Andronicus II ordered four new buttresses (Πυραμὶδας, Greek:"Piramídas") to be built in the eastern and northern parts of the church, financing them with the inheritance of his deceased wife, Irene. New cracks developed in the dome after the earthquake of October 1344, and several parts of the building collapsed on 19 May 1346; consequently, the church was closed until 1354, when repairs were undertaken by architects Astras and Peralta.
Mosque (1453–1935)
In 1453 Sultan Mehmed laid siege to Constantinople, driven in part by a desire to convert the city to Islam. The Sultan promised his troops three days of unbridled pillage if the city fell, after which he would claim its contents himself. Hagia Sophia was not exempted from the pillage, becoming its focal point as the invaders believed it to contain the greatest treasures of the city. Shortly after the city’s defenses collapsed, pillagers made their way to the Hagia Sophia and battered down its doors. Throughout the siege worshipers participated in the Holy Liturgy and Prayer of the Hours at the Hagia Sophia, and the church formed a refuge for many of those who were unable to contribute to the city’s defense. Trapped in the church, congregants and refugees became booty to be divided amongst the invaders. The building was desecrated and looted, and occupants enslaved or slaughtered; a few of the elderly and infirm were killed, and the remainder chained. Priests continued to perform Christian rites until stopped by the invaders. When the Sultan and his cohort entered the church he insisted it should be at once transformed into a mosque. One of the Ulama then climbed the pulpit and recited the Shahada.
Fountain (Şadırvan) for ritual ablutions
The mihrab located in the apse where the altar used to stand, pointing towards Mecca
As written above, immediately after the conquest of Constantinople in 1453, Mehmed II converted Hagia Sophia into the Aya Sofya Mosque. As described by several Western visitors (such as the Córdoban nobleman Pero Tafur and the Florentine Cristoforo Buondelmonti), the church was in a dilapidated state, with several of its doors off; sultan Mehmed II ordered the cleanup of the church and its conversion. He attended the first Friday prayer in the mosque on 1 June 1453. Aya Sofya became the first imperial mosque of Istanbul. To the corresponding Waqf were endowed most of the existing houses in the city and the area of the future Topkapı Palace. Through the imperial charters of 1520 / 926H and 1547 / 954 H shops and parts of the Grand Bazaar and other markets were added to the foundation.Before 1481 a small minaret was erected on the SW corner of the building, above the stair tower. Later, the subsequent sultan, Bayezid II (1481–1512), built another minaret at the NE corner. One of these crashed because of the earthquake of 1509, and around the middle of the 16th century they were both replaced by two diagonally opposite minarets built at the E and W corners of the edifice.
In the 16th century the sultan Suleiman the Magnificent (1520–1566) brought back two colossal candlesticks from his conquest of Hungary. They were placed on either side of the mihrab. During the reign of Selim II (1566–1577), the building started showing signs of fatigue and was extensively strengthened with the addition of structural supports to its exterior by the great Ottoman architect Mimar Sinan, who is also considered one of the world's first earthquake engineers. In addition to strengthening the historic Byzantine structure, Sinan built the two additional large minarets at the western end of the building, the original sultan's loge, and the Türbe (mausoleum) of Selim II to the southeast of the building in 1576-7 / 984 H. In order to do that, one year before parts of the Patriarchate at the S corner of the building were pulled down. Moreover, the golden crescent was mounted on the top of the dome, while a respect zone 35 arşin (about 24 m) wide was imposed around the building, pulling down all the houses which in the meantime had nested around it. Later his türbe hosted also 43 tombs of Ottoman princes. In 1594 / 1004 H Mimar (court architect) Davud Ağa built the türbe of Murad III (1574–1595), where the Sultan and his Valide, Safiye Sultan were later buried. The octagonal mausoleum of their son Mehmed III (1595–1603) and his Valide was built next to it in 1608 / 1017 H by royal architect Dalgiç Mehmet Aĝa. His Son Mustafa I (1617–1618; 1622–1623) let convert the Baptistery into his Türbe.
Later additions were the sultan's gallery, a minbar decorated with marble, a dais for a sermon and a loggia for a muezzin.
Murad III had also two large alabaster Hellenistic urns transported from Pergamon and placed on two sides of the nave.
In 1717, under Sultan Ahmed III (1703–1730), the crumbling plaster of the interior was renovated, contributing indirectly to the preservation of many mosaics, which otherwise would have been destroyed by mosque workers. In fact, it was usual for them to sell mosaics stones – believed to be talismans – to the visitors. Sultan Mahmud I ordered the restoration of the building in 1739 and added a medrese (a Koranic school, now the library of the museum), an Imaret (soup kitchen for distribution to the poor) and a library, and in 1740 a Şadirvan (fountain for ritual ablutions), thus transforming it into a külliye, i.e. a social complex. At the same time a new sultan's gallery and a new mihrab were built inside.
The most famous restoration of the Aya Sofya was ordered by Sultan Abdülmecid and completed by eight hundred workers between 1847 and 1849, under the supervision of the Swiss-Italian architect brothers Gaspare and Giuseppe Fossati. The brothers consolidated the dome and vaults, straightened the columns, and revised the decoration of the exterior and the interior of the building. The mosaics in the upper gallery were cleaned. The old chandeliers were replaced by new pendant ones. New gigantic circular-framed disks or medallions were hung on columns. They were inscribed with the names of Allah, the Prophet Muhammad, the first four caliphs Abu Bakr, Umar, Uthman and Ali, and the two grandchildren of Mohammed: Hassan and Hussain, by the calligrapher Kazasker Mustafa İzzed Effendi (1801–1877). In 1850 the architect Fossati built a new sultan's gallery in a Neo-Byzantine style connected to the royal pavilion behind the mosque. Outside the Aya Sofya, a timekeeper's building and a new madrasah were built. The minarets were altered so that they were of equal height. When the restoration was finished, the mosque was re-opened with ceremonial pomp on 13 July 1849.

Pyramidology (or pyramidism) refers to various religious or pseudoscientific speculations regarding pyramids, most often the Giza pyramid complex and the Great Pyramid of Giza in Egypt. Some "pyramidologists" also concern themselves with the monumental structures of pre-Columbian America (such as Teotihuacan, the Mesoamerican Maya civilization, and the Inca of the South American Andes), and the temples of Southeast Asia.
Some pyramidologists claim that the Great Pyramid of Giza has encoded within it predictions for the exodus of Moses from Egypt, the crucifixion of Jesus, the start of World War I, the founding of modern-day Israel in 1948, and future events including the beginning of Armageddon; this was discovered by using what they call "pyramid inches" to calculate the passage of time where one British inch equals one solar year.
Pyramidology reached its peak by the early 1980s. Interest revived when in 1992 and 1993 Rudolf Gantenbrink sent a miniature remote-controlled robot rover, known as upuaut, up one of the "air shafts" in the Queen's Chamber of the Great Pyramid of Giza. Upuaut discovered the shaft closed off by a stone block with decaying copper hooks attached to the outside. In 1994 Robert Bauval published the book The Orion Mystery, attempting to prove that the pyramids on the Giza plateau were built to mimic the stars in the belt of the constellation Orion, a claim that came to be known as the Orion correlation theory.
Types of pyramidology
The main types of pyramidological accounts involve one or more aspects which include: metrological: theories regarding the construction of the Great Pyramid of Giza by hypothetical geometric measurements numerological: theories that the measurements of the Great Pyramid and its passages have esoteric significance, and that their geometric measurements contain some encoded message. This form of pyramidology is popular within Christian Pyramidology (e.g. British Israelism and Bible Students). "pyramid power": claims originating in the late 1960s that pyramids as geometrical shapes possess supernatural powers pseudoarchaeological: varying theories that deny the pyramids were built to serve exclusively as tombs for the Pharaohs; alternative explanations regarding the construction of the pyramids (for example the use of long-lost knowledge; anti-gravity technology, etc...); and hypotheses that they were built by someone other than the historical Ancient Egyptians (e.g. early Hebrews, Atlanteans, or even extra-terrestrials)
History
Metrological
Metrological pyramidology dates to the 17th century. John Greaves, an English mathematician, astronomer and antiquarian, first took precise measurements of the Great Pyramid at Giza using the best mathematical instruments of the day. His data was published in Pyramidographia (1646) which theorized a geometric cubit was used by the builders of the Great Pyramid (see: Egyptian royal cubit). While Greave's measurements were objective, his metrological data was later misused by numerologists:
J. Greaves in his Pyramidographia, 1646, made an objective description of these structures, but using his measurements, some philosophers started to propose a more subjective reading of them: Kircher suggested that they had mystical and hidden meanings; Th. Shaw thought the Great Pyramid was a temple to Osiris; I. Newton created the concept of “sacred code” to denote one of the two supposed instruments used to erect them.
John Taylor
In his work The great pyramid; why was it built: & who built it? (1859) John Taylor described a possible connection with the dimensions of the pyramid and the golden ratio (see Kepler triangle). He also proposed that the inch used to build the Great Pyramid (see pyramid inch) was 1/25 of the "sacred cubit" (whose existence had earlier been postulated by Isaac Newton). Taylor was also the first to claim the pyramid was divinely inspired, contained a revelation and was built not by the Egyptians, but instead the Hebrews pointing to Biblical passages (Is. 19: 19-20; Job 38: 5-7) to support his theories.[8] For this reason Taylor is often credited as being the "founder of pyramidology". Martin Gardner noted:
[...] it was not until 1859 that Pyramidology was born. This was the year that John Taylor, an eccentric partner in a London publishing firm, issued his The Great Pyramid: Why was it Built? And Who Built it? [...] Taylor never visited the Pyramid, but the more he studied its structure, the more he became convinced that its architect was not an Egyptian, but an Israelite acting under divine orders. Perhaps it was Noah himself.
Christian pyramidology
British Israelism
Taylor in turn influenced the Astronomer Royal of Scotland Charles Piazzi Smyth, F.R.S.E., F.R.A.S., who made numerous numerological calculations on the pyramid and published them in a 664-page book Our Inheritance in the Great Pyramid (1864) followed by Life, and Work in the Great Pyramid (1867). These two works fused pyramidology with British Israelism and Smyth first linked the hypothetical pyramid inch to the British Imperial Unit system.
Smyth's theories were later expanded upon by early 20th century British Israelites such as Colonel Garnier (Great Pyramid: Its Builder & Its Prophecy, 1905), who began to theorise that chambers within the Great Pyramid contain prophetic dates which concern the future of the British, Celtic, or Anglo-Saxon peoples. However this idea originated with Robert Menzies, an earlier correspondent of Smyth's. David Davidson with H. Aldersmith wrote The Great Pyramid, Its Divine Message (1924) and further introduced the idea that Britain's chronology (including future events) may be unlocked from inside the Great Pyramid. This theme is also found in Basil Stewart's trilogy on the same subject: Witness of the Great Pyramid (1927), The Great Pyramid, Its Construction, Symbolism and Chronology (1931) and History and Significance of the Great Pyramid... (1935). More recently a four-volume set entitled Pyramidology was published by British Israelite Adam Rutherford (released between 1957–1972).[11] British Israelite author E. Raymond Capt also wrote Great Pyramid Decoded in 1971 followed by Study in Pyramidology in 1986.
Joseph A. Seiss
Joseph Seiss was a Lutheran minister who was a proponent of pyramidology. He wrote A Miracle in Stone: or, The Great Pyramid of Egypt in 1877. His work was popular with contemporary evangelical Christians.
Charles Taze Russell
In 1891 pyramidology reached a global audience when it was integrated into the works of Charles Taze Russell, founder of the Bible Student movement. Russell however denounced the British-Israelite variant of pyramidology in an article called The Anglo-Israelitish Question . Adopting Joseph Seiss's designation that the Great Pyramid of Giza was "the Bible in stone" Russell taught that it played a special part in God's plan during the "last days" basing his interpretation on Isaiah 19:19-20 which says - "In that day shall there be an altar (pile of stones) to the Lord in the midst of the land of Egypt, and a pillar (Hebrew matstebah, or monument) at the border thereof to the Lord. And it shall be for a sign, and for a witness unto the Lord of Hosts in the land of Egypt." Two brothers, archaeologists John and Morton Edgar, as personal associates and supporters of Russell, wrote extensive treatises on the history, nature, and prophetic symbolism of the Great Pyramid in relation to the then known archaeological history, along with their interpretations of prophetic and Biblical chronology. They are best known for their two-volume work Great Pyramid Passages and Chambers, published in 1910 and 1913.
Pyramid power
Pyramid power refers to the belief that the ancient Egyptian pyramids and objects of similar shape can confer a variety of benefits. Among these assumed properties are the ability to preserve foods, sharpen or maintain the sharpness of razor blades, improve health, function "as a thought-form incubator", trigger sexual urges, and cause other effects. Such unverified theories regarding pyramids are collectively known as pyramidology.
There is no scientific evidence that pyramid power exists.
Another set of speculations concerning pyramids have centered upon the possible existence of an unknown energy concentrated in pyramidical structures.
Pyramid energy was popularized in the early 1970s, particularly by New Age authors such as Patrick Flanagan (Pyramid Power: The Millennium Science, 1973), Max Toth and Greg Nielsen (Pyramid Power, 1974) and Warren Smith (Secret Forces of the Pyramids, 1975). These works focused on the alleged energies of pyramids in general, not solely the Egyptian pyramids. Toth and Nielsen for example reported experiments where "seeds stored in pyramid replicas germinated sooner and grew higher"
Although most Bible Student groups continue to support and endorse the study of pyramidology from a Biblical perspective, the Bible Students associated with the Watchtower Society, who chose ’Jehovah's Witnesses’ as their new name in 1931, have abandoned pyramidology entirely since 1928.In the 1930s, a French ironmonger[9] and pendulum-dowsing author, Antoine Bovis, developed the idea that small models of pyramids can preserve food. The story persists that Bovis, while standing inside the King's Chamber of the Great Pyramid in Egypt, saw a garbage can inside the chamber piled with dead animals that had wandered into the structure, noticed that these small carcasses were not decaying and inferred that the structure somehow preserved them. However, Bovis never claimed to have visited Egypt.In his self-published French-language booklet Bovis ascribes his discovery to reasoning and experiments in Europe using a dowsing pendulum:
I have supposed that Egyptians were already very good dowsers and had oriented their pyramid by means of rod and pendulum. Being unable to go there to experiment and verify the radiations of the Keops Pyramid, I have built with cardboard some pyramids that you can see now, and I was astonished when, having built a regular pyramid and oriented it, I found the positive at the East, the negative at the West, and at the North and the South, dual-positive and dual-negative...
A new supposition: since with the help of our positive 2000° magnetic plates we can mummify small animals, could the pyramid have the same property? I tried, and as you can observe with the small fish and the little piece of meat still hanging, I succeeded totally.
In 1949, inspired by Bovis, a Czechoslovakian named Karel Drbal applied for a patent on a "Pharaoh's shaving device", a model pyramid alleged to maintain the sharpness of razor blades. According to the patent (#91,304), "The method of maintaining the razor blades and straight razor blades sharp by placing them in the magnetic field in such a way that the sharp edge lies in the direction of the magnetic lines."Drbal alleged that his device would focus "the earth's magnetic field", although he did not make it clear how this would work, or whether the device's shape or materials exerted the effect.
Drbal's contention that razors could be sharpened or have their sharpness maintained by alignment with Earth's magnetic field was not new. In 1933, The Times carried letters claiming, "if I oriented my razor blades…N. and S. by the compass…they tend to last considerably longer"and "The idea of keeping razor blades in a magnetic field is not quite new. About the year 1900 I found this out…."
Sheila Ostrander and Lynn Schroeder, authors of the paranormal, visited Czechoslovakia in 1968, where they happened upon a cardboard pyramid manufactured commercially by Drbal. They met Drbal, and dedicated a chapter of their popular 1970 book Psychic Discoveries Behind the Iron Curtain to pyramid power. This book introduced both the concept of pyramid power and the story about Antoine Bovis to the English-speaking world.
Popularisation
Flanagan’s book was featured on the cover and in the lyrics of The Alan Parsons Project album Pyramid. "Pyramania", a song from the album, mocked the idea of pyramid power.
Pyramid power was the subject of a famous spoof by Martin Gardner in his "Mathematical Games" column in the Scientific American issue of June 1974, featuring his favorite characters Dr. Matrix and Iva Matrix.
The theories behind Pyramid Power convinced the Onan Family, hotel and condo developers in Gurnee, Illinois, to build the "Pyramid House" in 1977.
Summerhill Pyramid Winery in Kelowna, British Columbia built a four-story replica of the Great Pyramid, alleged by the winery to improve the quality of wine aged within it.
A religion founded in 1975, called Summum, completed the construction of a pyramid called the Summum Pyramid in Salt Lake City, Utah in 1979.
Pyramid power was used by the Toronto Maple Leafs and their coach Red Kelly during the 1975–76 quarter-final series, to counter the Philadelphia Flyers' use of Kate Smith's rendering of "God Bless America". Kelly hung a plastic model of a pyramid in the team's clubhouse after a pair of away defeats at the start of the series, and each player took turns standing under it for exactly four minutes. The Maple Leafs managed to win all three of their home matches before losing the series' decisive game seven.
Terry Pratchett's fantasy novel Pyramids incorporates elements of the theory when an industry develops based around pyramids' ability to stop time.
It is common in New Age magazines to see advertisements for open metal-poled pyramids large enough to meditate under. The New Age group Share International, founded by Benjamin Creme, practices a form of meditation called 'Transmission Meditation' using an open metal-poled tetrahedron in order to tune into the cosmic energy of Maitreya and other spiritual masters.

Pseudoarchaeology
Lewis Spence in his An Encyclopaedia of Occultism (1920) summed up on the earliest of pseudoarcheological claims on the ancient Egyptian pyramids as follows:
"...in the 1880s, Ignatius Donnelly had suggested that the Great Pyramid had been built by the descendants of the Atlanteans. That idea was picked up in the 1920s by Manly Palmer Hall who went on to suggest that they were the focus of the ancient Egyptian wisdom schools. Edgar Cayce built upon Hall's speculations."
Ignatius Donnelly and later proponents of the hyperdiffusionist view of history claimed that all pyramid structures across the world had a common origin. Donelly claimed this common origin was in Atlantis. While Grafton Elliot Smith claimed Egypt, writing: "Small groups of people, moving mainly by sea, settled at certain places and there made rude imitations of the Egyptian monuments of the Pyramid Age."
Ancient astronauts
Several proponents of ancient astronauts claim that the Great Pyramid of Giza was constructed by extraterrestrial beings, or influenced by them (e.g., through their advanced technology). Proponents include Erich von Däniken, Robert Charroux, W. Raymond Drake, and Zecharia Sitchin. According to Erich Von Däniken, the Great Pyramid has advanced numerological properties which could not have been known to the ancient Egyptians and so must have been passed down by extraterrestrials: "...the height of the pyramid of Cheops, multiplied by a thousand million—98,000,000 miles—corresponds approximately to the distance between the Earth and the sun".
Orion correlation theory
Robert Bauval and Graham Hancock (1996) have both suggested that the 'ground plan' of the three main Egyptian pyramids was physically established in c. 10,500 BC, but that the pyramids were built around 2,500 BC. This theory was based on their initial claims regarding the alignment of the Giza pyramids with Orion ("…the three pyramids were a terrestrial map of the three stars of Orion's belt"— Hancock's Fingerprints of the Gods, 1995, p. 375) are later joined with speculation about the age of the Great Sphinx (Hancock and Bauval, Keeper of Genesis, published 1996, and in 1997 in the U.S. as The Message of the Sphinx).
Advanced technology
Linked to the pseudoarchaeological ancient astronaut theory and Orion correlation theory are related claims that the Great Pyramid was constructed by the use of an advanced lost technology. Proponents of this theory often link this hypothetical advanced technology to extraterrestrials but also Atlanteans, Lemurians or a legendary lost race.Notable proponents include Christopher Dunn and David Hatcher Childress. Graham Hancock also in his book Fingerprints of the Gods assigned the 'ground plan' of the three main Egyptian pyramids, in his theory to an advanced progenitor civilization which possessed advanced technology.
Alan F. Alford
Author Alan F. Alford interprets the entire Great Pyramid in the context of ancient Egyptian religion. Alford takes as his starting point the golden rule that the pharaoh had to be buried in the earth, i.e. at ground level or below, and this leads him to conclude that Khufu was interred in an ingeniously concealed cave whose entrance is today sealed up in the so-called Well Shaft adjacent to a known cave called the Grotto. He has lobbied the Egyptian authorities to explore this area of the pyramid with ground penetrating radar.
The cult of creation theory also provided the basis for Alford's next idea: that the sarcophagus in the King's Chamber - commonly supposed to be Khufu's final resting place - actually enshrined iron meteorites.He maintains, by reference to the Pyramid Texts, that this iron was blasted into the sky at the time of creation, according to the Egyptians' geocentric way of thinking. Alford says the King's Chamber, with its upward inclined dual 'airshafts', was built to capture the magic of this mythical moment.
Alford's most speculative idea is that the King's Chamber generated low frequency sound via its 'airshafts', the purpose being to re-enact the sound of the earth splitting open at the time of creation
The Cathedral of Pisa , officially the Primate Cathedral of Santa Maria Assunta , in the center of the Piazza del Duomo, also known as Piazza dei Miracoli , is the cathedral of the Archdiocese of Pisa as well as the Primate church .
A masterpiece of the Romanesque , in particular of the Pisan Romanesque , it represents the tangible testimony of the prestige and wealth achieved by the maritime republic of Pisa at the moment of its apogee.
Its construction began in 1063 ( 1064 according to the Pisan calendar in force at the time) by the architect Buscheto , with the tenth part of the spoils of the Palermo campaign in Sicily against the Muslims ( 1063 ) led by Giovanni Orlandi belonging to the Orlandi family [ 1] . Different stylistic elements blend together: classical, Lombard-Emilian , Byzantine and in particular Islamic, proving the international presence of Pisan merchants in those times. In that same year the reconstruction of the Basilica of San Marco in Venice also began , so it may also be that there was a rivalry between the two maritime republics at the time to create the most beautiful and sumptuous place of worship.
The church was built in an area outside the early medieval city walls , to symbolize the power of Pisa which did not require protection. The chosen area was already used in the Lombard era as a necropolis and, already in the early 11th century , an unfinished church was built which was to be dedicated to Santa Maria. The new large church of Buscheto, in fact, was initially called Santa Maria Maggiore until it was finally named after Santa Maria Assunta.
In 1092 the church changed from a simple cathedral to being primatial, the title of primate having been conferred on Archbishop Daiberto by Pope Urban II , an honor which today is only formal. The cathedral was consecrated in 1118 by Pope Gelasius II , as recorded by the inscription placed internally on the counter-façade at the top left.
In the first half of the 12th century the cathedral was enlarged under the direction of the architect Rainaldo , who lengthened the naves by adding three bays in front of the old facade [2] according to the Buscheto style, widened the transept and designed a new facade, completed by the workers led by the sculptors Guglielmo and Biduino . The date of the start of the works is uncertain: immediately after Buscheto's death around the year 1120 , according to some, around the year 1140 according to others. The end of the works dates back to 1180 , as documented by the date affixed to the bronze doors by Bonanno Pisano on the main door.
The current appearance of the complex building is the result of repeated restoration campaigns that took place in different eras. The first radical interventions followed the disastrous fire on the night between 24 and 25 October 1595 [3] , which destroyed many decorative interventions and following which the roof was rebuilt and the three bronze doors of the facade were made, the work of sculptors from the workshop of Giambologna , including Gasparo Mola and Pietro Tacca . Starting from the eighteenth century, the progressive covering of the internal walls began with large paintings on canvas, the "quadroni" with Stories of Pisan blesseds and saints , executed by the main artists of the time thanks to the initiative of some citizens who financed themselves by creating a special business.
The Napoleonic spoliations of the Cathedral of Pisa and the Opera del Duomo were significant, many works converged on the Louvre where they are exhibited today, including The Triumph of Saint Thomas Aquinas among the Doctors of the Church by Benozzo Gozzoli , now in the Louvre, Death of San Bernardo dell'Orcagna and San Benedetto , the work of Andrea del Castagno .
Among the various noteworthy interventions, it is worth mentioning the dismantling of Giovanni Pisano's pulpit which was reassembled only in 1926 in a different position and with several parts missing, including the staircase, and the dismantling of the monument to Henry VII created by Lupo di Francesco which was located in front of the door of San Ranieri and subsequently replaced by a simplified and symbolic version.
The subsequent interventions took place during the nineteenth century and affected both the internal and external decorations, which in many cases, especially the sculptures on the facade, were replaced by copies (the originals are in the Museo dell'Opera del duomo ).
The building has a Latin cross shape with a large dome at the intersection of the arms. The longitudinal body, divided into five naves , extends over ten bays . This plan continues in the choir with two more bays and a final apse crowning the central nave alone. The transept has 4 bays on each side (or six if we include the two in common with the longitudinal body) and has three naves with apses ending on both sides. In the center four large pillars delimit the rectangular cross ending at the top with a large elliptical dome.
The building, like the bell tower, has sunk perceptibly into the ground, and some defects in the construction are clearly visible, such as the differences in level between Buscheto's nave and the extension by Rainaldo (the bays towards the west and the facade) .
The exterior of the cathedral is mainly in white and gray marble although the older stones placed at the lower levels of the longitudinal body are of other poorer material. There is no shortage of valuable materials, especially on the facade, where there are multicolored marble inlays, mosaics and also bronze objects from war booty, including the Griffin used on the top of the roof at the back (east side), perhaps taken from Palermo in 1061 ( today there is a copy on the roof, the original is in the Museo dell'Opera del Duomo ).
The longitudinal body, transept and choir have a rich facing punctuated by three orders or floors. On the lower floor, long rows of pilasters supporting blind arches , in turn enclosing lozenges or windows, punctuate the space on all sides of the building with very few interruptions (only the apse of the right transept). The second floor still has pilasters but this time these do not support blind arches and are rather architraved , a motif interrupted only in the apse of the right transept (where blind arches appear again) and in the main apse where two orders of loggias are visible . In addition to the windows and lozenges, inlaid oculi also appear between the pilasters . The third floor has columns or semi-columns which again support blind arches (longitudinal body and choir) or an architrave (transept) with the usual alternation of windows, lozenges and inlaid oculi.
The raised round arches on the facade and in the main apse recall elements of Muslim art from Sicily . The blind arches with lozenges recall the similar structures of the churches of Armenia . Even the ellipsoidal dome rebuilt after the fire of 1595, surmounted by a lantern, recalls Islamic architecture.
The gray and white marble façade , decorated with colored marble inserts, was built by master Rainaldo in the 12th century and finished by 1180. On the lower floor, the seven blind arches which enclose lozenges, one every two, echo the same motif which spreads over the remaining three sides of the Cathedral. On the façade, however, the ornamentation becomes richer: semi-columns placed against semi-rectangular pillars replace the slender pilaster strips on the sides and are surmounted by Corinthian or figurative capitals. The arches are embellished with a rich texture of vegetal motifs and the lozenges are also larger and inlaid with multicolored marble. The empty spaces between the three portals have marble slabs forming square or rectangular motifs and are embellished with horizontal ornamental bands with plant motifs. The empty spaces between the arches are also filled with marble tablets inlaid with geometric or animal motifs. Noteworthy is the one at the top right of the main portal which depicts a Christian brandishing the cross between two beasts and the writing of Psalm 21 : Salva me ex ore leonis et a cornibus unicornium humilitatem meam (Save me from the mouth of the lion Lord and my humility from the unicorn's horns), the original of which is preserved in the nearby Museo dell'Opera del Duomo .
Of the three portals , the central one has larger dimensions and is enclosed by two columns decorated with vegetal motifs which support, above the capitals, two lions to symbolize the two "faces" of Christ the Judge , the one who condemns on the left and the one who rewards and is merciful on the right (note the saved and protected lamb between the legs). All three portals have eighteenth-century mosaics by Giuseppe Modena da Lucca in their lunettes depicting the Assumption of the Virgin (centre), Santa Reparata (left) and Saint John the Baptist (right). The bronze doors were made by various artists of the caliber of Giambologna , after the fire of 1595, replacing the two wooden side doors and the bronze-covered wooden royal door by Bonanno Pisano which bore the date of 1180 (seen and described before the fire) to testify to the completion of the façade in that year. To the left of the north left portal, there is Buscheto's tomb.
The four upper floors are characterized by four orders of superimposed loggias, divided by finely sculpted frames, behind which there are single , double and triple lancet windows . Many of the friezes on the arches and frames were redone in the 17th century after the fire of 1595, while the polychrome marble inlays between the arches are original. Even higher up, to crown it, the Madonna and Child by Andrea Pisano and, in the corners, the four evangelists by Giovanni Pisano (early 14th century).
Contrary to what one might think, since ancient times the faithful have entered the Cathedral through the door of San Ranieri , located at the back in the transept of the same name, in front of the bell tower. This is because the nobles of the city went to the cathedral coming from via Santa Maria which leads to that transept. This door was cast around 1180 by Bonanno Pisano , and is the only door to escape the fire of 1595 which heavily damaged the church. The door is decorated with twenty-four panels depicting stories from the New Testament. This door is one of the first produced in Italy in the Middle Ages, after the importation of numerous examples from Constantinople , (in Amalfi , in Salerno , in Rome , in Montecassino , in Venice ...) and one admires an entirely Western sensitivity, which breaks away from the Byzantine tradition.
The original gràdule of the Duomo, designed by Giovanni Pisano and dating back to the end of the 13th century, were removed in 1865 and replaced by the current churchyard . These gràdule consisted of small walls, decorated with squares carved with figures of animals and heads, close to the external perimeter of the cathedral and served as a base for the numerous sarcophagi of the Roman era which, during the medieval era, were reused for the burials of nobles (among whom Beatrice of Canossa stands out ) and heroes. Currently some fragments are visible in the Museo dell'Opera del Duomo, while the sarcophagi were all moved within the enclosure of the monumental cemetery .
The lower register of the facade is not very rich in figurative sculptural decorations unlike other contemporary Romanesque cathedrals, but it still gives a rich meaning both to its unitary components and a complex allegory in its overall vision. To read the latter you need to start from the left where the outermost capital of the left side portal shows two ferocious lions devouring weak prey and two human figures further behind. The former represent the struggle between good and evil where evil dominates [6] , but behind them the figure of the old man stacking wood and the young man towering over a ram perhaps represent Abraham and Isaac and the sacrificial ram (or two peasants virtuous at work) which show preparation for God's plan of salvation. The arch that starts from the same capital shows a row of dragons that two virtuous human figures in the center are forced to face in the continuous struggle between good and evil. [6]
At the level of the central portal we enter the New Testament which concretizes the plan of salvation brought about by God starting from Abraham . It is the portal dedicated to the Virgin of the Assumption and her Son , whose divine judgment is represented by the two lions of justice, the one that condemns on the left and the one that protects and saves on the right with the little lamb protected between its legs, for Divine Mercy or Justice whatever it is. [6] The 42 stylized human figurines present on the decorated arch show the 42 generations that separate, according to the Gospel of Matthew , Abraham from Jesus Christ (the figurines are actually 43 but perhaps due to renovation needs or other reasons for filling the frieze ). This transition from the old to the new is strengthened by the two marble inlays in the intrados of the main arch where a ferocious dragon and a lion facing each other depicting the perennial struggle between the evil forces (left inlay) [6] become two equally ferocious unicorns but in the middle to whom a Christian appears brandishing a cross to defend himself from them (inlay on the right) and where we read in Latin:
de ore leonis libera me domine et a cornibus unicorni humilitatem mea ("Save me from the lion's mouth, Lord, and my humility from the unicorn's horns", psalm 21 ).
The last element of this complex narrative is the outermost capital of the right portal, which acts as a pendant to that of the left portal from which we started. We are well beyond the coming of Jesus where the evil lions, previously in the foreground, are relegated to a backward and out of the way position, always ready to strike as shown by the heads turned back and the tongue out, but in a contorted position due to the continuous escapes to which the Savior and the Church forces them to do. [6] In a prominent position there are now two naked human figurines, the souls of those saved by the Savior through the intercession of the Church , which are composed and serene figures with large eyes, well anchored with their arms to the garland of the capital and the feet resting well on the acanthus leaves, symbol of men of faith, victorious over sin and blessed by faith rather than merit.
The five- nave interior is covered in black and white marble, with monolithic columns of gray marble and capitals of the Corinthian order . The arches of the ten bays are round arches (those of the central nave) or raised arches in the Moorish style of the time (those of the side naves).
The central nave has a seventeenth-century gilded coffered ceiling, in gilded and painted wood, by the Florentines Domenico and Bartolomeo Atticciati ; it bears the Medici coat of arms in gold . Presumably the ancient ceiling had a structure with exposed wooden trusses. The four side naves have a cross-shaped plastered roof. The coffered roof is also present in the choir and in the central nave of the transept, while a plastered barrel roof is present in the side naves of the transept. The coverage of the lateral naves of the transept at the level of the two bays shared with the lateral naves of the longitudinal body is curious: these are cross-shaped (as in the lateral naves of the longitudinal body), but are higher (as in the lateral naves of the transept) . There is also a women's gallery of Byzantine origin that runs along the entire church, including the choir and transept and which has a coffered roof (central body) or wooden beams (transept). Even higher up, thin and deep windows allow the church to be lit.
The interior suggests a spatial effect that has some analogy with that of mosques , for the use of raised arches, for the alternation of white and green marble bands, for the unusual elliptical dome , of oriental inspiration, and for the presence of women's galleries with solid monolithic granite columns in the mullioned windows , a clear sign of Byzantine influence. The architect Buscheto had welcomed stimuli from the Islamic Levant and Armenia . [7]
Only part of the medieval decorative interventions survived the fire of 1595. Among these is the fresco with the Madonna and Child by the Pisan Master of San Torpè in the triumphal arch (late 13th-early 14th century), and below it the Cosmatesque flooring , of a certain rarity outside the borders of Lazio . It was made of marble inlays with geometric "opus alexandrinum" motifs (mid- 12th century ). Other late medieval fresco fragments have survived, among them Saint Jerome on one of the four central pillars and Saint John the Baptist , a Crucifix and Saint Cosimo and Damian on the pillar near the entrance door, partially hidden by the compass .
At the meeting point between the transept and the central body the dome rises, the decoration of which represented one of the last interventions carried out after the fire mentioned. Painted with the rare encaustic painting technique [8] (or wax on wall) [9] , the dome represents the Virgin in glory and saints ( 1627 - 1631 ), a masterpiece by the Pisan Orazio Riminaldi , completed after his death. which occurred in 1630 due to the plague, by his brother Girolamo . The decoration underwent a careful restoration which returned it to its original splendor in 2018.
The presbytery, ending in a curved apse, presents a great variety of ornaments. Above, in the basin, the large mosaic of Christ enthroned between the Virgin and Saint John is made famous by the face of Saint John, a work by Cimabue from 1302 which miraculously survived the fire of 1595. Precisely that Saint John the Evangelist was the The last work created by Cimabue before his death and the only one for which certified documentation exists. It evokes the mosaics of Byzantine churches and also Norman ones, such as Cefalù and Monreale , in Sicily . The mosaic, largely created by Francesco da Pisa, was finished by Vincino da Pistoia with the depiction of the Madonna on the left side ( 1320 ).
The main altar, from the beginning of the twentieth century, features six Angels contemporary with Ludovico Poliaghi , and in the center the bronze Crucifix by Giambologna , of which there are also the two candle-holder Angels at the end of the rich marble transenna, while the third Angel on the column to the left of the altar is by Stoldo Lorenzi .
Below, behind the main altar, there is the large decorative complex of the Tribune, composed of 27 paintings depicting episodes from the Old Testament and Christological stories. Begun before the fire with the works of Andrea del Sarto (three canvases, Saint Agnes , Saints Catherine and Margaret and Saints Peter and John the Baptist ) del Sodoma and Domenico Beccafumi ( Stories of Moses and the Evangelists ), it was completed after this calamity with the works of several Tuscan painters, including Orazio Riminaldi .
The pulpit , a masterpiece by Giovanni Pisano (1302-1310), survived the fire, but was dismantled during the restoration work and was not reassembled until 1926 . With its articulated architectural structure and complex sculptural decoration, the work is one of the largest narratives in fourteenth-century images that reflects the renewal and religious fervor of the era. The episodes from the Life of Christ are carved in an expressive language on the slightly curved panels . The structure is polygonal, as in the similar previous examples, in the baptistery of Pisa , in the cathedral of Siena and in the church of Sant'Andrea in Pistoia , but for the first time the panels are slightly curved, giving a new idea of circularity in its type. Equally original are: the presence of caryatids , sculpted figures in place of simple columns, which symbolize the Virtues ; the adoption of spiral brackets instead of arches to support the mezzanine floor; the sense of movement, given by the numerous figures that fill every empty space.
For these qualities combined with the skilful narrative art of the nine scenes it is generally considered Giovanni's masterpiece and more generally of Italian Gothic sculpture. The pulpit commissioned from Giovanni replaced a previous one , created by Guglielmo ( 1157 - 1162 ), which was sent to the cathedral of Cagliari . Since there is no documentation of what the pulpit looked like before its dismantling, it was rebuilt in a different position from the original one and, certainly, with the parts not in the same order and orientation as had been thought. It is not known whether or not he had a marble staircase.
The right transept is occupied by the Chapel of San Ranieri , patron saint of the city, whose relics are preserved in the magnificent shrine on the altar. Also in the chapel, on the left, is preserved part of the fragmentary tomb of Henry VII of Luxembourg , Holy Roman Emperor , who died in 1313 in Buonconvento while besieging Florence in vain . The tomb, also dismantled and reassembled, (it was sculpted by Tino di Camaino in 1313 - 1315 ) and was originally placed in the center of the apse, as a sign of the Ghibelline faith of the city. It was also a much more complex sculptural monument, featuring various statues. Moved several times for political reasons, it was also separated into several parts (some inside the church, some on the facade, some in the Campo Santo). Today we find the sarcophagus in the church with the deceased depicted lying on it, according to the fashion in vogue at that time, and the twelve apostles sculpted in bas-relief. The lunette painted with curtain-holding angels is instead a later addition from the workshop of Domenico Ghirlandaio (end of the 15th century ). The other remains of the monument have been reassembled in the nearby Museo dell'Opera del Duomo . The left transept is occupied by the Chapel of the Blessed Sacrament, in the center of which is the large silver tabernacle designed by Giovan Battista Foggini (1678-86).
On the numerous side altars there are sixteenth-seventeenth century paintings. Among the paintings housed on the minor altars, we remember the Madonna delle Grazie with saints, by the Florentine mannerist Andrea del Sarto, and the Madonna enthroned with saints in the right transept, by Perin del Vaga , a pupil of Raphael , both finished by Giovanni Antonio Sogliani . The canvas with the Dispute of the Sacrament is in Baroque style, by the Sienese Francesco Vanni , and the Cross with saints by the Genoese Giovanni Battista Paggi . Particularly venerated is the image of the thirteenth-century Madonna and Child , known as the Madonna di sotto gli organi , attributed to the Volterra native Berlinghiero Berlinghieri .
Pisa is a city and comune in Tuscany, central Italy, straddling the Arno just before it empties into the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for its leaning tower, the city contains more than twenty other historic churches, several medieval palaces, and bridges across the Arno. Much of the city's architecture was financed from its history as one of the Italian maritime republics.
The city is also home to the University of Pisa, which has a history going back to the 12th century, the Scuola Normale Superiore di Pisa, founded by Napoleon in 1810, and its offshoot, the Sant'Anna School of Advanced Studies.
History
For a chronological guide, see Timeline of Pisa.
Ancient times
The most believed hypothesis is that the origin of the name Pisa comes from Etruscan and means 'mouth', as Pisa is at the mouth of the Arno river.
Although throughout history there have been several uncertainties about the origin of the city of Pisa, excavations made in the 1980s and 1990s found numerous archaeological remains, including the fifth century BC tomb of an Etruscan prince, proving the Etruscan origin of the city, and its role as a maritime city, showing that it also maintained trade relations with other Mediterranean civilizations.
Ancient Roman authors referred to Pisa as an old city. Virgil, in his Aeneid, states that Pisa was already a great center by the times described; and gives the epithet of Alphēae to the city because it was said to have been founded by colonists from Pisa in Elis, near which the Alpheius river flowed. The Virgilian commentator Servius wrote that the Teuti founded the town 13 centuries before the start of the common era.
The maritime role of Pisa should have been already prominent if the ancient authorities ascribed to it the invention of the naval ram. Pisa took advantage of being the only port along the western coast between Genoa (then a small village) and Ostia. Pisa served as a base for Roman naval expeditions against Ligurians and Gauls. In 180 BC, it became a Roman colony under Roman law, as Portus Pisanus. In 89 BC, Portus Pisanus became a municipium. Emperor Augustus fortified the colony into an important port and changed the name to Colonia Iulia obsequens.
Pisa supposedly was founded on the shore, but due to the alluvial sediments from the Arno and the Serchio, whose mouth lies about 11 km (7 mi) north of the Arno's, the shore moved west. Strabo states that the city was 4.0 km (2.5 mi) away from the coast. Currently, it is located 9.7 km (6 mi) from the coast. However, it was a maritime city, with ships sailing up the Arno. In the 90s AD, a baths complex was built in the city.
Late Antiquity and Early Middle Ages
During the last years of the Western Roman Empire, Pisa did not decline as much as the other cities of Italy, probably due to the complexity of its river system and its consequent ease of defence. In the seventh century, Pisa helped Pope Gregory I by supplying numerous ships in his military expedition against the Byzantines of Ravenna: Pisa was the sole Byzantine centre of Tuscia to fall peacefully in Lombard hands, through assimilation with the neighbouring region where their trading interests were prevalent. Pisa began in this way its rise to the role of main port of the Upper Tyrrhenian Sea and became the main trading centre between Tuscany and Corsica, Sardinia, and the southern coasts of France and Spain.
After Charlemagne had defeated the Lombards under the command of Desiderius in 774, Pisa went through a crisis, but soon recovered. Politically, it became part of the duchy of Lucca. In 860, Pisa was captured by vikings led by Björn Ironside. In 930, Pisa became the county centre (status it maintained until the arrival of Otto I) within the mark of Tuscia. Lucca was the capital but Pisa was the most important city, as in the middle of tenth century Liutprand of Cremona, bishop of Cremona, called Pisa Tusciae provinciae caput ("capital of the province of Tuscia"), and a century later, the marquis of Tuscia was commonly referred to as "marquis of Pisa". In 1003, Pisa was the protagonist of the first communal war in Italy, against Lucca. From the naval point of view, since the ninth century, the emergence of the Saracen pirates urged the city to expand its fleet; in the following years, this fleet gave the town an opportunity for more expansion. In 828, Pisan ships assaulted the coast of North Africa. In 871, they took part in the defence of Salerno from the Saracens. In 970, they gave also strong support to Otto I's expedition, defeating a Byzantine fleet in front of Calabrese coasts.
11th century
The power of Pisa as a maritime nation began to grow and reached its apex in the 11th century, when it acquired traditional fame as one of the four main historical maritime republics of Italy (Repubbliche Marinare).
At that time, the city was a very important commercial centre and controlled a significant Mediterranean merchant fleet and navy. It expanded its powers in 1005 through the sack of Reggio Calabria in the south of Italy. Pisa was in continuous conflict with some 'Saracens' - a medieval term to refer to Arab Muslims - who had their bases in Corsica, for control of the Mediterranean. In 1017, Sardinian Giudicati were militarily supported by Pisa, in alliance with Genoa, to defeat the Saracen King Mugahid, who had settled a logistic base in the north of Sardinia the year before. This victory gave Pisa supremacy in the Tyrrhenian Sea. When the Pisans subsequently ousted the Genoese from Sardinia, a new conflict and rivalry was born between these major marine republics. Between 1030 and 1035, Pisa went on to defeat several rival towns in Sicily and conquer Carthage in North Africa. In 1051–1052, the admiral Jacopo Ciurini conquered Corsica, provoking more resentment from the Genoese. In 1063, Admiral Giovanni Orlandi, coming to the aid of the Norman Roger I, took Palermo from the Saracen pirates. The gold treasure taken from the Saracens in Palermo allowed the Pisans to start the building of their cathedral and the other monuments which constitute the famous Piazza del Duomo.
In 1060, Pisa had to engage in their first battle with Genoa. The Pisan victory helped to consolidate its position in the Mediterranean. Pope Gregory VII recognised in 1077 the new "Laws and customs of the sea" instituted by the Pisans, and emperor Henry IV granted them the right to name their own consuls, advised by a council of elders. This was simply a confirmation of the present situation, because in those years, the marquis had already been excluded from power. In 1092, Pope Urban II awarded Pisa the supremacy over Corsica and Sardinia, and at the same time raising the town to the rank of archbishopric.
Pisa sacked the Tunisian city of Mahdia in 1088. Four years later, Pisan and Genoese ships helped Alfonso VI of Castilla to push El Cid out of Valencia. A Pisan fleet of 120 ships also took part in the First Crusade, and the Pisans were instrumental in the taking of Jerusalem in 1099. On their way to the Holy Land, the ships did not miss the occasion to sack some Byzantine islands; the Pisan crusaders were led by their archbishop Daibert, the future patriarch of Jerusalem. Pisa and the other Repubbliche Marinare took advantage of the crusade to establish trading posts and colonies in the Eastern coastal cities of the Levant. In particular, the Pisans founded colonies in Antiochia, Acre, Jaffa, Tripoli, Tyre, Latakia, and Accone. They also had other possessions in Jerusalem and Caesarea, plus smaller colonies (with lesser autonomy) in Cairo, Alexandria, and of course Constantinople, where the Byzantine Emperor Alexius I Comnenus granted them special mooring and trading rights. In all these cities, the Pisans were granted privileges and immunity from taxation, but had to contribute to the defence in case of attack. In the 12th century, the Pisan quarter in the eastern part of Constantinople had grown to 1,000 people. For some years of that century, Pisa was the most prominent commercial and military ally of the Byzantine Empire, overcoming Venice itself.
12th century
In 1113, Pisa and Pope Paschal II set up, together with the count of Barcelona and other contingents from Provence and Italy (Genoese excluded), a war to free the Balearic Islands from the Moors; the queen and the king of Majorca were brought in chains to Tuscany. Though the Almoravides soon reconquered the island, the booty taken helped the Pisans in their magnificent programme of buildings, especially the cathedral, and Pisa gained a role of pre-eminence in the Western Mediterranean.
In the following years, the powerful Pisan fleet, led by archbishop Pietro Moriconi, drove away the Saracens after ferocious battles. Though short-lived, this Pisan success in Spain increased the rivalry with Genoa. Pisa's trade with Languedoc, Provence (Noli, Savona, Fréjus, and Montpellier) were an obstacle to Genoese interests in cities such as Hyères, Fos, Antibes, and Marseille.
The war began in 1119 when the Genoese attacked several galleys on their way home to the motherland, and lasted until 1133. The two cities fought each other on land and at sea, but hostilities were limited to raids and pirate-like assaults.
In June 1135, Bernard of Clairvaux took a leading part in the Council of Pisa, asserting the claims of Pope Innocent II against those of Pope Anacletus II, who had been elected pope in 1130 with Norman support, but was not recognised outside Rome. Innocent II resolved the conflict with Genoa, establishing Pisan and Genoese spheres of influence. Pisa could then, unhindered by Genoa, participate in the conflict of Innocent II against king Roger II of Sicily. Amalfi, one of the maritime republics (though already declining under Norman rule), was conquered on August 6, 1136; the Pisans destroyed the ships in the port, assaulted the castles in the surrounding areas, and drove back an army sent by Roger from Aversa. This victory brought Pisa to the peak of its power and to a standing equal to Venice. Two years later, its soldiers sacked Salerno.
New city walls, erected in 1156 by Consul Cocco Griffi
In the following years, Pisa was one of the staunchest supporters of the Ghibelline party. This was much appreciated by Frederick I. He issued in 1162 and 1165 two important documents, with these grants: Apart from the jurisdiction over the Pisan countryside, the Pisans were granted freedom of trade in the whole empire, the coast from Civitavecchia to Portovenere, a half of Palermo, Messina, Salerno and Naples, the whole of Gaeta, Mazara, and Trapani, and a street with houses for its merchants in every city of the Kingdom of Sicily. Some of these grants were later confirmed by Henry VI, Otto IV, and Frederick II. They marked the apex of Pisa's power, but also spurred the resentment of other cities such as Lucca, Massa, Volterra, and Florence, thwarting their aim to expand towards the sea. The clash with Lucca also concerned the possession of the castle of Montignoso and mainly the control of the Via Francigena, the main trade route between Rome and France. Last, but not least, such a sudden and large increase of power by Pisa could only lead to another war with Genoa.
Genoa had acquired a dominant position in the markets of southern France. The war began in 1165 on the Rhône, when an attack on a convoy, directed to some Pisan trade centres on the river, by the Genoese and their ally, the count of Toulouse, failed. Pisa, though, was allied to Provence. The war continued until 1175 without significant victories. Another point of attrition was Sicily, where both the cities had privileges granted by Henry VI. In 1192, Pisa managed to conquer Messina. This episode was followed by a series of battles culminating in the Genoese conquest of Syracuse in 1204. Later, the trading posts in Sicily were lost when the new Pope Innocent III, though removing the excommunication cast over Pisa by his predecessor Celestine III, allied himself with the Guelph League of Tuscany, led by Florence. Soon, he stipulated[clarification needed] a pact with Genoa, too, further weakening the Pisan presence in southern Italy.
To counter the Genoese predominance in the southern Tyrrhenian Sea, Pisa strengthened its relationship with its traditional Spanish and French bases (Marseille, Narbonne, Barcelona, etc.) and tried to defy the Venetian rule of the Adriatic Sea. In 1180, the two cities agreed to a nonaggression treaty in the Tyrrhenian and the Adriatic, but the death of Emperor Manuel Comnenus in Constantinople changed the situation. Soon, attacks on Venetian convoys were made. Pisa signed trade and political pacts with Ancona, Pula, Zara, Split, and Brindisi; in 1195, a Pisan fleet reached Pola to defend its independence from Venice, but the Serenissima soon reconquered the rebel sea town.
One year later, the two cities signed a peace treaty, which resulted in favourable conditions for Pisa, but in 1199, the Pisans violated it by blockading the port of Brindisi in Apulia. In the following naval battle, they were defeated by the Venetians. The war that followed ended in 1206 with a treaty in which Pisa gave up all its hopes to expand in the Adriatic, though it maintained the trading posts it had established in the area. From that point on, the two cities were united against the rising power of Genoa and sometimes collaborated to increase the trading benefits in Constantinople.
13th century
In 1209 in Lerici, two councils for a final resolution of the rivalry with Genoa were held. A 20-year peace treaty was signed, but when in 1220, the emperor Frederick II confirmed his supremacy over the Tyrrhenian coast from Civitavecchia to Portovenere, the Genoese and Tuscan resentment against Pisa grew again. In the following years, Pisa clashed with Lucca in Garfagnana and was defeated by the Florentines at Castel del Bosco. The strong Ghibelline position of Pisa brought this town diametrically against the Pope, who was in a dispute with the Holy Roman Empire, and indeed the pope tried to deprive Pisa of its dominions in northern Sardinia.
In 1238, Pope Gregory IX formed an alliance between Genoa and Venice against the empire, and consequently against Pisa, too. One year later, he excommunicated Frederick II and called for an anti-Empire council to be held in Rome in 1241. On May 3, 1241, a combined fleet of Pisan and Sicilian ships, led by the emperor's son Enzo, attacked a Genoese convoy carrying prelates from northern Italy and France, next to the isle of Giglio (Battle of Giglio), in front of Tuscany; the Genoese lost 25 ships, while about a thousand sailors, two cardinals, and one bishop were taken prisoner. After this major victory, the council in Rome failed, but Pisa was excommunicated. This extreme measure was only removed in 1257. Anyway, the Tuscan city tried to take advantage of the favourable situation to conquer the Corsican city of Aleria and even lay siege to Genoa itself in 1243.
The Ligurian republic of Genoa, however, recovered fast from this blow and won back Lerici, conquered by the Pisans some years earlier, in 1256.
The great expansion in the Mediterranean and the prominence of the merchant class urged a modification in the city's institutes. The system with consuls was abandoned, and in 1230, the new city rulers named a capitano del popolo ("people's chieftain") as civil and military leader. Despite these reforms, the conquered lands and the city itself were harassed by the rivalry between the two families of Della Gherardesca and Visconti. In 1237 the archbishop and the Emperor Frederick II intervened to reconcile the two rivals, but the strains continued. In 1254, the people rebelled and imposed 12 Anziani del Popolo ("People's Elders") as their political representatives in the commune. They also supplemented the legislative councils, formed of noblemen, with new People's Councils, composed by the main guilds and by the chiefs of the People's Companies. These had the power to ratify the laws of the Major General Council and the Senate.
Decline
The decline is said to have begun on August 6, 1284, when the numerically superior fleet of Pisa, under the command of Albertino Morosini, was defeated by the brilliant tactics of the Genoese fleet, under the command of Benedetto Zaccaria and Oberto Doria, in the dramatic naval Battle of Meloria. This defeat ended the maritime power of Pisa and the town never fully recovered; in 1290, the Genoese destroyed forever the Porto Pisano (Pisa's port), and covered the land with salt. The region around Pisa did not permit the city to recover from the loss of thousands of sailors from the Meloria, while Liguria guaranteed enough sailors to Genoa. Goods, however, continued to be traded, albeit in reduced quantity, but the end came when the Arno started to change course, preventing the galleys from reaching the city's port up the river. The nearby area also likely became infested with malaria. The true end came in 1324, when Sardinia was entirely lost to the Aragonese.
Always Ghibelline, Pisa tried to build up its power in the course of the 14th century, and even managed to defeat Florence in the Battle of Montecatini (1315), under the command of Uguccione della Faggiuola. Eventually, however, after a long siege, Pisa was occupied by Florentines in 1405.[9] Florentines corrupted the capitano del popolo ("people's chieftain"), Giovanni Gambacorta, who at night opened the city gate of San Marco. Pisa was never conquered by an army. In 1409, Pisa was the seat of a council trying to set the question of the Great Schism. In the 15th century, access to the sea became more difficult, as the port was silting up and was cut off from the sea. When in 1494, Charles VIII of France invaded the Italian states to claim the Kingdom of Naples, Pisa reclaimed its independence as the Second Pisan Republic.
The new freedom did not last long; 15 years of battles and sieges by the Florentine troops led by Antonio da Filicaja, Averardo Salviati and Niccolò Capponi were made, but they failed to conquer the city. Vitellozzo Vitelli with his brother Paolo were the only ones who actually managed to break the strong defences of Pisa and make a breach in the Stampace bastion in the southern west part of the walls, but he did not enter the city. For that, they were suspected of treachery and Paolo was put to death. However, the resources of Pisa were getting low, and at the end, the city was sold to the Visconti family from Milan and eventually to Florence again. Livorno took over the role of the main port of Tuscany. Pisa acquired a mainly cultural role spurred by the presence of the University of Pisa, created in 1343, and later reinforced by the Scuola Normale Superiore di Pisa (1810) and Sant'Anna School of Advanced Studies (1987).
Pisa was the birthplace of the important early physicist Galileo Galilei. It is still the seat of an archbishopric. Besides its educational institutions, it has become a light industrial centre and a railway hub. It suffered repeated destruction during World War II.
Since the early 1950s, the US Army has maintained Camp Darby just outside Pisa, which is used by many US military personnel as a base for vacations in the area.
Geography
Climate
Pisa has a borderline humid subtropical climate (Köppen climate classification: Cfa) and Mediterranean climate (Köppen climate classification: Csa). The city is characterized by cool to mild winters and hot summers. This transitional climate allows Pisa to have summers with moderate rainfall. Rainfall peaks in autumn. Snow is rare. The highest officially recorded temperature was 39.5 °C (103.1 °F) on 22 August 2011 and the lowest was −13.8 °C (7.2 °F) on 12 January 1985.
Culture
Gioco del Ponte
In Pisa there was a festival and game fr:Gioco del Ponte (Game of the Bridge) which was celebrated (in some form) in Pisa from perhaps the 1200s down to 1807. From the end of the 1400s the game took the form of a mock battle fought upon Pisa's central bridge (Ponte di Mezzo). The participants wore quilted armor and the only offensive weapon allowed was the targone, a shield-shaped, stout board with precisely specified dimensions. Hitting below the belt was not allowed. Two opposing teams started at opposite ends of the bridge. The object of the two opposing teams was to penetrate, drive back, and disperse the opponents' ranks and to thereby drive them backwards off the bridge. The struggle was limited to forty-five minutes. Victory or defeat was immensely important to the team players and their partisans, but sometimes the game was fought to a draw and both sides celebrated.
In 1677 the battle was witnessed by Dutch travelling artist Cornelis de Bruijn. He wrote:
"While I stayed in Livorno, I went to Pisa to witness the bridge fight there. The fighters arrived fully armored, wearing helmets, each carrying their banner, which was planted at both ends of the bridge, which is quite wide and long. The battle is fought with certain wooden implements made for this purpose, which they wear over their arms and are attached to them, with which they pummel each other so intensely that I saw several of them carried away with bloody and crushed heads. Victory consists of capturing the bridge, in the same way as the fistfights in Venice between the it:Castellani and the Nicolotti."
In 1927 the tradition was revived by college students as an elaborate costume parade. In 1935 Vittorio Emanuele III with the royal family witnessed the first revival of a modern version of the game, which has been pursued in the 20th and 21st centuries with some interruptions and varying degrees of enthusiasm by Pisans and their civic institutions.

Main sights
The Leaning Tower of Pisa.
While the bell tower of the cathedral, known as "the leaning Tower of Pisa", is the most famous image of the city, it is one of many works of art and architecture in the city's Piazza del Duomo, also known, since the 20th century, as Piazza dei Miracoli (Square of Miracles), to the north of the old town center. The Piazza del Duomo also houses the Duomo (the Cathedral), the Baptistry and the Campo Santo (the monumental cemetery). The medieval complex includes the above-mentioned four sacred buildings, the hospital and few palaces. All the complex is kept by the Opera (fabrica ecclesiae) della Primaziale Pisana, an old non profit foundation that has operated since the building of the Cathedral in 1063 to maintain the sacred buildings. The area is framed by medieval walls kept by the municipal administration.
Other sights include:
Santo Stefano dei Cavalieri, church sited on Piazza dei Cavalieri, and also designed by Vasari. It had originally a single nave; two more were added in the 17th century. It houses a bust by Donatello, and paintings by Vasari, Jacopo Ligozzi, Alessandro Fei, and Pontormo. It also contains spoils from the many naval battles between the Cavalieri (Knights of St. Stephan) and the Turks between the 16th and 18th centuries, including the Turkish battle pennant hoisted from Ali Pacha's flagship at the 1571 Battle of Lepanto.
St. Sixtus. This small church, consecrated in 1133, is also close to the Piazza dei Cavalieri. It was used as a seat of the most important notarial deeds of the town, also hosting the Council of Elders. It is today one of the best preserved early Romanesque buildings in town.
St. Francis. The church of San Francesco may have been designed by Giovanni di Simone, built after 1276. In 1343 new chapels were added and the church was elevated. It has a single nave and a notable belfry, as well as a 15th-century cloister. It houses works by Jacopo da Empoli, Taddeo Gaddi and Santi di Tito. In the Gherardesca Chapel are buried Ugolino della Gherardesca and his sons.
San Frediano. This church, built by 1061, has a basilica interior with three aisles, with a crucifix from the 12th century. Paintings from the 16th century were added during a restoration, including works by Ventura Salimbeni, Domenico Passignano, Aurelio Lomi, and Rutilio Manetti.
San Nicola. This medieval church built by 1097, was enlarged between 1297 and 1313 by the Augustinians, perhaps by the design of Giovanni Pisano. The octagonal belfry is from the second half of the 13th century. The paintings include the Madonna with Child by Francesco Traini (14th century) and St. Nicholas Saving Pisa from the Plague (15th century). Noteworthy are also the wood sculptures by Giovanni and Nino Pisano, and the Annunciation by Francesco di Valdambrino.
Santa Maria della Spina. A small white marble church alongside the Arno, is attributed to Lupo di Francesco (1230), is another excellent Gothic building.
San Paolo a Ripa d'Arno. The church was founded around 952 and enlarged in the mid-12th century along lines similar to those of the cathedral. It is annexed to the Romanesque Chapel of St. Agatha, with an unusual pyramidal cusp or peak.
San Pietro in Vinculis. Known as San Pierino, it is an 11th-century church with a crypt and a cosmatesque mosaic on the floor of the main nave.
Borgo Stretto. This medieval borgo or neighborhood contains strolling arcades and the Lungarno, the avenues along the river Arno. It includes the Gothic-Romanesque church of San Michele in Borgo (990). There are at least two other leaning towers in the city, one at the southern end of central Via Santa Maria, the other halfway through the Piagge riverside promenade.
Medici Palace. The palace was once a possession of the Appiano family, who ruled Pisa in 1392–1398. In 1400 the Medici acquired it, and Lorenzo de' Medici sojourned here.
Orto botanico di Pisa. The botanical garden of the University of Pisa is Europe's oldest university botanical garden.
Palazzo Reale. The ("Royal Palace"), once belonged to the Caetani patrician family. Here Galileo Galilei showed to Grand Duke of Tuscany the planets he had discovered with his telescope. The edifice was erected in 1559 by Baccio Bandinelli for Cosimo I de Medici, and was later enlarged including other palaces. The palace is now a museum.
Palazzo Gambacorti. This palace is a 14th-century Gothic building, and now houses the offices of the municipality. The interior shows frescoes boasting Pisa's sea victories.
Palazzo Agostini. The palace is a Gothic building also known as Palazzo dell'Ussero, with its 15th-century façade and remains of the ancient city walls dating back to before 1155. The name of the building comes from the coffee rooms of Caffè dell'Ussero, historic meeting place founded on September 1, 1775.
Mural Tuttomondo. A modern mural, the last public work by Keith Haring, on the rear wall of the convent of the Church of Sant'Antonio, painted in June 1989.
Museums
Museo dell'Opera del Duomo: exhibiting among others the original sculptures of Nicola Pisano and Giovanni Pisano, the Islamic Pisa Griffin, and the treasures of the cathedral.
Museo delle Sinopie: showing the sinopias from the camposanto, the monumental cemetery. These are red ocher underdrawings for frescoes, made with reddish, greenish or brownish earth colour with water.
Museo Nazionale di San Matteo: exhibiting sculptures and paintings from the 12th to 15th centuries, among them the masterworks of Giovanni and Andrea Pisano, the Master of San Martino, Simone Martini, Nino Pisano and Masaccio.
Museo Nazionale di Palazzo Reale: exhibiting the belongings of the families that lived in the palace: paintings, statues, armors, etc.
Museo Nazionale degli Strumenti per il Calcolo: exhibiting a collection of instruments used in science, between a pneumatic machine of Van Musschenbroek and a compass which probably belonged to Galileo Galilei.
Museo di storia naturale dell'Università di Pisa (Natural History Museum of the University of Pisa), located in the Certosa di Calci, outside the city. It houses one of the largest cetacean skeletons collection in Europe.
Palazzo Blu: temporary exhibitions and cultural activities center, located in the Lungarno, in the heart of the old town, the palace is easy recognizable because it is the only blue building.
Cantiere delle Navi di Pisa - The Pisa's Ancient Ships Archaeological Area: A museum of 10,650 square meters – 3,500 archaeological excavation, 1,700 laboratories and one restoration center – that visitors can visit with a guided tour.[19] The Museum opened in June 2019 and has been located inside to the 16th-century Medicean Arsenals in Lungarno Ranieri Simonelli, restored under the supervision of the Tuscany Soprintendenza. It hosts a remarkable collection of ceramics and amphoras dated back from the 8th century BCE to the 2nd century BC, and also 32 ships dated back from the second century BCE and the seventh century BC. Four of them are integrally preserved and the best one is the so-called Barca C, also named Alkedo (written in the ancient Greek characters). The first boat was accidentally discovered in 1998 near the Pisa San Rossore railway station and the archeological excavations were completed 20 years later.

Calendar and Zodiac
The year is usually represented by the 12 signs of the zodiac, arranged either as a concentric circle inside the 24-hour dial, or drawn onto a displaced smaller circle, which is a projection of the ecliptic, the path of the sun and planets through the sky, and the plane of the Earth's orbit.

An astronomical clock is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the sun, moon, zodiacal constellations, and sometimes major planets.

Bekannteste astronomische Uhr am Rathaus in Tübingen:
Das Werk der Tübinger Rathausuhr läuft seit knapp über 500 Jahren so exakt, dass es nur alle 40 Jahre etwas korrigiert werden muss.
~ J. Stöffler hat die astronomische Uhr vermutlich im Jahre 1511 in seiner Werkstatt in Jungingen konstruiert.
~ Von 1522 - 1530 bewohnte er mit seinen Studenten (u.a. P. Melanchton) das Gebäude Kronenstraße 11 am Marktplatz (Herberge "Zur Krone", heute Café Ranitzky), von wo er die Astronomische Uhr sehen konnte.
- Bis heute zeigt die Uhr zuverlässig die Mondphasen an und gibt Hinweise auf den Stand der Sonne im Tierkreis. Darüber hinaus weist die Uhr auf Sonnen- und Mondfinsternisse sowie auf weitere Himmelsdaten hin.
Aber einzigartig wird die Tübinger Uhr erst durch den Drachenzeiger: Durch ihn ist sie die weltweit älteste, die Sonnen- und Mondfinsternisse anzeigen kann. Liegen Drachenzeiger, Sonnenzeiger und Mondzeiger genau übereinander, dann befinden sich Sonne, Mond und Erde wie an einer Perlenschnur aufgezogen genau auf einer geraden Linie.
An der Richtung der einzelnen Zeiger kann man dann ablesen, ob es eine Sonnen- oder eine Mondfinsternis gibt. Zeigen Mond- und Sonnenzeiger in die gleiche Richtung, ist es eine Sonnenfinsternis. Zeigen Mond und Sonnenzeiger in entgegengesetzte Richtungen, ist es eine Mondfinsternis.
Als der Mathematik- und Astronomieprofessor Johannes Stöffler (1452-1531) mit dem Bau der Astronomischen Uhr begann, dachten die meisten Menschen noch, alle Planeten drehten sich um die Erde. Andere Meinungen hatten im frühen 16. Jahrhundert unter dem Druck der Kirche keine Chance, aber Stöffler schaffte es, trotz aller Einflussnahme, eine Uhr zu bauen, die die Himmelsmechanik perfekt darstellte.

Leben
Justingen
Das Dorf Justingen liegt auf der Hochfläche der Schwäbischen Alb auf 750 m NN zwischen Schelklingen, Münsingen und Laichingen.
. Das Dorf Justingen hatte im Mittelalter seinen eigenen Ortsadel, genannt von Justingen, gesessen auf der Burg Justingen über dem Schmiechtal und Hütten, eng verwandt mit den Herren von Steußlingen, Gundelfingen und Wildenstein.
Stöffler: Johannes St., von Justingen (Schwäbische Alb) , geboren am 10. December 1452, † am 16. Februar 1531 zu Blaubeuren, berühmter Mathematiker, Astronom und Astrologe. — Aus demselben Dorfe Justingen (tgl. württembergisches Oberamt Münsingen) stammend, wie der Humanist Heinrich Bebel und die beiden Vergenhanse (Naucleros), ist er möglicherweise mit den letzteren verwandt. Am 21. April 1472 wurde er an der Universität Ingolstadt immatriculirt. Er hat später dieselbe als eine "herrliche Hochschule" bezeichnet, die ihm in den freien Künsten eine süße Mutter gewesen sei. Es ist ungewiß, wann er die Pfarrei Justingen bekam, doch scheint ihn der Besitz der Pfründe nicht dauernd an Justingen gebunden zu haben. 1496 stellte er in Konstanz eine Uhr im dortigen Münster auf; 1499 ist er in Ulm u. s. w. Seine Gelehrsamkeit verschaffte ihm viele Freunde, darunter Gelehrte vom höchsten Rufe, wie z. B. Johannes Reuchlin; auch wurde er von wißbegierigen Männern in seinem entlegenen Pfarrdorfe aufgesucht, so z. B. von Paul Scriptoris und Konrad Pellican im J. 1499. Auch mit Johann v. Dalberg, dem kurpfälzischen Kanzler und Bischof von Worms, dem berühmten Gönner der Humanisten, stand er in freundschaftlicher Verbindung. Er fertigte für diesen einen Himmelsglobus und hat den gefeierten Mäcenas in seinem Schlosse zu Ladenburg aufgesucht. Auf Wunsch des Herzogs Ulrich von Württemberg übernahm er 1511, schon 59 Jahre alt, die Professur der Mathematik an der Hochschule Tübingen. Die Vertreibung des Herzogs, der sich für seinen Gehalt verbürgt hatte, brachte dem betagten Gelehrten schlimme Zeiten, weil er die ihm von der Pfarrei Justingen zugesicherten 90 Gulden nicht mehr ausbezahlt bekam. Der Rechtshandel darüber beschäftigte sogar den Erzherzog Ferdinand, der in Abwesenheit des Herzogs Ulrich Württemberg verwaltete. Die Pest vertrieb St. im J. 1530 mit einem Theil der Hochschule aus Tübingen nach Blaubeuren, wo er auch gestorben ist. Begraben wurde er in der St. Georgenkirche zu Tübingen.
Die Blüthezeit seiner akademischen Thätigkeit fällt vor 1519, während|welcher Zeit (von 1512—1518) auch Philipp Melanchthon sein Schüler war. Dieser hat tiefe Eindrücke von dem großen Gelehrten empfangen, und der astrologische Wahnglaube, dem Melanchthon sein ganzes Leben huldigte, dürfte auf St. zurückzuführen sein. Zwischen beiden Männern hat sich trotz der großen Altersverschiedenheit rasch ein pietätvolles Verhältniß entwickelt. Schon 1513 begleitete Melanchthon eine Schrift Stöffler's mit empfehlenden Versen, und die erste erhaltene Rede Melanchthon's: De artibus liberalibus ist St. gewidmet. Noch in späteren Jahren pflegte Melanchthon in seinen Vorlesungen Aussprüche und Anekdoten des verehrten Tübinger Gelehrten zu erzählen.
Von seinen jetzt selten gewordenen Schriften mögen folgende genannt werden: "Almanach nova plurimis annis venturis inservientia: per Joannem Stöfflerinum Justingensem et Jacobum Pflaumen Ulmensem accuratissime supputata etc." (Ulm 1499); "Tabulae astronomicae. Verarum mediarumque coniunctionum et oppositionum Solis et Lunae etc." (Tübingen 1514); "Elucidatio fabricae ususque astrolabii etc." (Oppenheim 1513); "Calendarium magnum Romanum" (Oppenheim 1518); "Expurgatio adversus divinationum XXIII anni suspitiones etc." (Tübingen (1523); "Ephemeridum opus etc." (Tübingen 1531). Erst nach dem Tode des Verfassers erschienen, bildet die Fortsetzung der Almanach nova. "In Procli Diadochi autoris gravissimi sphaeram mundi etc. Commentarius" (Tübingen 1534). Diese Schrift wurde von L. Schrader herausgegeben. Nicht gedruckt wurden seine "Commentaria in Ptolemaei libros geographicos", die zum Theil verbrannt sind. Die zwei erhaltenen Bücher der Handschrift befinden sich auf der Tübinger Universitätsbibliothek. Es werden noch weitere Schriften Stöffler's genannt, z. B. auch von Vossius, von denen jedoch zweifelhaft ist, ob sie wirklich erschienen sind.
Ziemliches Unheil stiftete St. durch seine astrologischen Träumereien an, indem er auf das J. 1524 eine neue Sintflut prophezeite, wodurch sich manche Menschen zu thörichten Handlungen verleiten ließen. Obgleich statt der Sintflut eine große Trockenheit eintrat, scheint er doch nichts an Ansehen eingebüßt zu haben. Zur Kalenderverbesserung machte er elf Vorschläge. Aber auch als Kosmograph und Mechaniker war er ausgezeichnet; heute noch besitzt die Gymnasialbibliothek zu Konstanz einen merkwürdigen Globus coelestis, welchen St. für den Weihbischof Daniel von Konstanz verfertigt hat. Andere ähnliche Werke seiner Geschicklichkeit, von denen die Zeitgenossen berichten, sind zu Grunde gegangen. — Von den zwei erhaltenen Bildern Stöffler's finden sich gutgelungene Reproductionen in den unten erwähnten Arbeiten Moll's und Steiff's.

1507 wurde der gelehrte Pfarrer und Instrumentenbauer Johannes Stöffler von Herzog Ulrich von Württemberg als erster Astronomielehrer an die Landesuniversität Tübingen
berufen. Stöffler wurde durch seine astronomisch berechneten Kalender und Tabellen, Uhren und Himmelsgloben weithin bekannt, die u.a auch von Nikolaus Kopernikus genutzt wurden.
1511 baute Stöffler eine astronomische Uhr für das Tübinger Rathaus.
Die aus der Reformation hervorgegangenen Kirchen verzögerten die Annahme aus ideologischen Gründen, denn die Reform war vom Papst ausgegangen.
Papst Gregor war auch Astronom.
Der heute weltweit verbreitete gregorianische Kalender (benannt nach Papst Gregor XIII.) entstand Ende des 16. Jahrhunderts durch eine Reform des julianischen Kalenders und wurde 1582 mit der päpstlichen Bulle Inter gravissimas verordnet. Er löste im Laufe der Zeit sowohl den julianischen als auch zahlreiche andere Kalender ab. Die letzte Umstellung auf den gregorianischen Kalender erfolgte 1949 in China.

Johannes Stöffler (10 décembre 1452, probablement à Blaubeuren ou Justingen – 16 février 1531 à Blaubeuren) était un mathématicien, astronome, fabricant d'instruments astronomiques, astrologue et prêtre allemand. Il était professeur à l'université de Tübingen.
-
Neben seinen kirchlichen Pflichten beschäftigte sich Stöffler mit der Astronomie und Astrologie sowie der Herstellung astronomischer Instrumente, Globen und Uhren, wozu er sich im Pfarrhaus auch eine Werkstatt einrichtete. Mit seinen Erzeugnissen erwarb er sich schnell einen Ruf. So erhielt er einen Auftrag des Konstanzer Weihbischofs für einen Himmelsglobus, sein erstes bedeutendes Werk, den er 1493 anfertigte. Seine in mehreren Auflagen erschienene Schrift Elucidatio fabricae ususque astrolabii galt bei Astronomen und Feldmesser lange Zeit als Standardwerk.
Zu seinen bekanntesten Schülern zählen Philipp Melanchthon und Sebastian Münster.

Die nach Papst Gregor XIII. benannte Gregorianische Kalenderreform im Jahre 1582
bewirkte im Wesentlichen, dass das kalendarische Tages-Datum „21. März“ wieder in unmittelbare Nähe zu dem astronomischen Ereignis des Primaräquinoktiums (Frühlings-Tagnachtgleiche der nördlichen Erdhalbkugel) gebracht wurde. Infolge der schematischen Anwendung der Schalttags-Vorschriften der Julianischen Kalenderreform nach der augustëischen Korrektur hatte sich der Kalender und mit ihm das Tagesdatum „21. März“ im Laufe der Jahrhunderte derart verschoben, dass dieses im Jahre 1582 erst zehn Tage nach dem Eintritt des astronomischen Ereignisses „Primar-Äquinoktium“ erschien. Die Wiederherstellung der während des Konzils zu Nicäa im Jahre 325 bestehenden astronomisch-kalendarischen Verhältnisse im Jahre 1583 wurde im Rahmen der päpstlichen Bulle Inter gravissimas dadurch bewirkt, dass im Jahre 1582 in der Tageszählung des Kalenders die zwischen dem 4. Oktober und dem 15. Oktober liegenden Zähltage ausgelassen wurden. Im Kalender des Jahres 1582 folgte also auf den 4. Oktober der 15. Oktober. Im Folgejahr zeigte dann ein Blick auf den Tageskalender am Tage des astronomischen Ereignisses „Primar-Äquinoktium“ – wie im Jahre 325 – wieder den 21. März. Um eine erneute Weg-Verrückung des Kalender-Datums vom Tage des Primar-Äquinoktiums zu vermeiden, bestimmten die Reform-Vorschriften schließlich, dass diejenigen Säkularjahre (Jahre, deren Zahl ein Vielfaches von 100 ist) ausnahmsweise dann keine Schalttage enthalten, wenn ihre Zahl dividiert durch 400 keine natürliche Zahl ergibt. Letzteres war der Fall in den Jahren 1700, 1800 und 1900.

Seoul – officially the Seoul Special City – is the capital and largest metropolis of the Republic of Korea (commonly known as South Korea), forming the heart of the Seoul Capital Area, which includes the surrounding Incheon metropolis and Gyeonggi province, the world's 16th largest city. It is home to over half of all South Koreans along with 678,102 international residents.
Situated on the Han River, Seoul's history stretches back more than two thousand years when it was founded in 18 BCE by Baekje, one of the Three Kingdoms of Korea. It continued as the capital of Korea under the Joseon Dynasty. The Seoul Capital Area contains five UNESCO World Heritage Sites: Changdeok Palace, Hwaseong Fortress, Jongmyo Shrine, Namhansanseong and the Royal Tombs of the Joseon Dynasty. Seoul is surrounded by mountains, the tallest being Mt. Bukhan, the world's most visited national park per square foot. Modern landmarks include the iconic N Seoul Tower, the gold-clad 63 Building, the neofuturistic Dongdaemun Design Plaza, Lotte World, the world's second largest indoor theme park, Moonlight Rainbow Fountain, the world's longest bridge fountain and the Sevit Floating Islands. The birthplace of K-pop and the Korean Wave, Seoul received over 10 million international visitors in 2014, making it the world's 9th most visited city and 4th largest earner in tourism.
Today, Seoul is considered a leading and rising global city, resulting from an economic boom called the Miracle on the Han River which transformed it to the world's 4th largest metropolitan economy with a GDP of US$845.9 billion in 2014 after Tokyo, New York City and Los Angeles. In 2015, it was rated Asia's most livable city with the second highest quality of life globally by Arcadis. A world leading technology hub centered on Gangnam and Digital Media City, the Seoul Capital Area boasts 15 Fortune Global 500 companies such as Samsung, the world's largest technology company, as well as LG and Hyundai-Kia. In 2014, the city's GDP per capita (PPP) of $39,786 was comparable to that of France and Finland. Ranked sixth in the Global Power City Index and Global Financial Centres Index, the metropolis exerts a major influence in global affairs as one of the five leading hosts of global conferences.
Seoul is the world's most wired city and ranked first in technology readiness by PwC's Cities of Opportunity report. It is served by the KTX high-speed rail and the Seoul Subway, providing 4G LTE, WiFi and DMB inside subway cars. Seoul is connected via AREX to Incheon International Airport, rated the world's best airport nine years in a row (2005–2013) by Airports Council International. Lotte World Tower, a 556-metre supertall skyscraper with 123 floors, has been built in Seoul and become the OECD's tallest in 2016, with the world's tallest art gallery. Its Lotte Cinema houses the world's largest cinema screen. Seoul's COEX Mall is the world's largest underground shopping mall.
Seoul hosted the 1986 Asian Games, 1988 Summer Olympics, 2002 FIFA World Cup, the Miss Universe 1980 pageant, and the 2010 G-20 Seoul summit. A UNESCO City of Design, Seoul was named the 2010 World Design Capital.
ETYMOLOGY
The city has been known in the past by the names Wirye-seong (Hangul: 위례성; Hanja: 慰禮城, during the Baekje era), Hanju (Hangul: 한주; Hanja: 漢州, during the Silla era), Namgyeong (Hangul: 남경; Hanja: 南京, during the Goryeo era), Hanseong (Hangul: 한성; Hanja: 漢城, during both the Baekje and Joseon eras), Hanyang (Hangul: 한양; Hanja: 漢陽, during the Joseon era), Gyeongseong (京城, during the colonial era).
During Japan's annexation in Korea, "Hanseong" (Hangul: 한성; Hanja: 漢城) was renamed to "Keijō" (京城, or Template:Korean 한국, Gyeongseong) by the Imperial authorities to prevent confusion with the hanja '漢', as it also refers to the Han Chinese. In reality, the ancient name of Seoul, Hanseong (Hangul: 한성; Hanja: 漢城), originally had the meaning of "big" or "vast".
Its current name originated from the Korean word meaning "capital city," which is believed to be derived from the word Seorabeol (Hangul: 서라벌; Hanja: 徐羅伐), which originally referred to Gyeongju, the capital of Silla.
Unlike most place names in Korea, "Seoul" has no corresponding hanja (Chinese characters used in the Korean language). On January 18, 2005, Seoul government officially changed its official Chinese language name to Shou'er (simplified Chinese: 首尔; traditional Chinese: 首爾; pinyin: Shǒu'ěr) from the historic Hancheng (simplified Chinese: 汉城; traditional Chinese: 漢城; pinyin: Hànchéng), of which use is becoming less common.
HISTOY
Settlement of the Han River area, where present-day Seoul is located, began around 4000 BC.
Seoul is first recorded as Wiryeseong, the capital of Baekje (founded in 18 BC) in the northeastern Seoul area. There are several city walls remaining in the area that date from this time. Pungnaptoseong, an earthen wall just outside Seoul, is widely believed to have been at the main Wiryeseong site. As the Three Kingdoms competed for this strategic region, control passed from Baekje to Goguryeo in the 5th century, and from Goguryeo to Silla in the 6th century.
In the 11th century Goryeo, which succeeded Unified Silla, built a summer palace in Seoul, which was referred to as the "Southern Capital". It was only from this period that Seoul became a larger settlement. When Joseon replaced Goryeo, the capital was moved to Seoul (also known as Hanyang and later as Hanseong), where it remained until the fall of the dynasty. The Gyeongbok Palace, built in the 14th century, served as the royal residence until 1592. The other large palace, Changdeokgung, constructed in 1405, served as the main royal palace from 1611 to 1872.
Originally, the city was entirely surrounded by a massive circular stone wall to provide its citizens security from wild animals, thieves and attacks. The city has grown beyond those walls and although the wall no longer stands (except along Bugaksan Mountain (Hangul: 북악산; Hanja: 北岳山), north of the downtown area), the gates remain near the downtown district of Seoul, including most notably Sungnyemun (commonly known as Namdaemun) and Heunginjimun (commonly known as Dongdaemun). During the Joseon dynasty, the gates were opened and closed each day, accompanied by the ringing of large bells at the Bosingak belfry. In the late 19th century, after hundreds of years of isolation, Seoul opened its gates to foreigners and began to modernize. Seoul became the first city in East Asia to introduce electricity in the royal palace, built by the Edison Illuminating Company and a decade later Seoul also implemented electrical street lights.
Much of the development was due to trade with foreign countries like France and United States. For example, the Seoul Electric Company, Seoul Electric Trolley Company, and Seoul Fresh Spring Water Company were all joint Korean–American owned enterprises. In 1904, an American by the name of Angus Hamilton visited the city and said, "The streets of Seoul are magnificent, spacious, clean, admirably made and well-drained. The narrow, dirty lanes have been widened, gutters have been covered, roadways broadened. Seoul is within measurable distance of becoming the highest, most interesting and cleanest city in the East.
"After the annexation treaty in 1910, the Empire of Japan annexed Korea and renamed the city Gyeongseong ("Kyongsong" in Korean and "Keijo" in Japanese). Japanese technology was imported, the city walls were removed, some of the gates demolished. Roads became paved and Western-style buildings were constructed. The city was liberated at the end of World War II.
In 1945, the city was officially named Seoul, and was designated as a special city in 1949.
During the Korean War, Seoul changed hands between the Russian/Chinese-backed North Korean forces and the American-backed South Korean forces several times, leaving the city heavily damaged after the war. The capital was temporarily relocated to Busan. One estimate of the extensive damage states that after the war, at least 191,000 buildings, 55,000 houses, and 1,000 factories lay in ruins. In addition, a flood of refugees had entered Seoul during the war, swelling the population of the city and its metropolitan area to an estimated 1.5 million by 1955.
Following the war, Seoul began to focus on reconstruction and modernization. As Korea's economy started to grow rapidly from the 1960s, urbanization also accelerated and workers began to move to Seoul and other larger cities. From the 1970s, the size of Seoul administrative area greatly expanded as it annexed a number of towns and villages from several surrounding counties.
According to 2012 census data, the population of the Seoul area makes up around 20% of the total population of South Korea, Seoul has become the economic, political and cultural hub of the country, with several Fortune Global 500 companies, including Samsung, SK Holdings, Hyundai, POSCO and LG Group headquartered there.
Seoul was the host city of the 1986 Asian Games and 1988 Summer Olympics as well as one of the venues of the Football World Cup 2002.
GEOGRAPHY
Seoul is in the northwest of South Korea. Seoul proper comprises 605.25 km2, with a radius of approximately 15 km, roughly bisected into northern and southern halves by the Han River. The Han River and its surrounding area played an important role in Korean history. The Three Kingdoms of Korea strove to take control of this land, where the river was used as a trade route to China (via the Yellow Sea). The river is no longer actively used for navigation, because its estuary is located at the borders of the two Koreas, with civilian entry barred. Historically, the city was during the Joseon Dynasty bounded by the Seoul Fortress Wall, which stretched between the four main mountains in central Seoul: Namsan, Naksan, Bukaksan and Inwangsan. The city is bordered by eight mountains, as well as the more level lands of the Han River plain and western areas. Due to its geography and to economic development policies, Seoul is a very polycentric city. The area that was the old capital in the Joseon Dynasty, and mostly comprises Jongno District and Jung District, constitutes the historical and political center of the city. However, for example, the city's financial capital is widely considered to be in Yeouido, while its economic capital is Gangnam District.
CLIMATE
Seoul is either classified as a humid subtropical climate (Köppen Cwa), using the −3 °C isotherm of the original Köppen scheme, or a humid continental climate (Köppen Dwa), using the 0 °C isotherm preferred by some climatologists. Summers are generally hot and humid, with the East Asian monsoon taking place from June until September. August, the warmest month, has average high and low temperatures of 29.6 and 22.4 °C with higher temperatures possible. Winters are often cold to freezing with average January high and low temperatures of 1.5 and −5.9 °C and are generally much drier than summers, with an average of 28 days of snow annually. Sometimes, temperatures do drop dramatically to below −10.0 °C, in odd occasions rarely as low as −15.0 °C in the mid winter period between January and February.
ADMINISTRATIVE DISTRICTS
Seoul is divided into 25 gu (Hangul: 구; Hanja: 區) (district). The gu vary greatly in area (from 10 to 47 km2) and population (from fewer than 140,000 to 630,000). Songpa has the most people, while Seocho has the largest area. The government of each gu handles many of the functions that are handled by city governments in other jurisdictions. Each gu is divided into "dong" (Hangul: 동; Hanja: 洞) or neighbourhoods. Some gu have only a few dong while others like Jongno District have a very large number of distinct neighbourhoods. Gu of Seoul consist of 423 administrative dongs (Hangul: 행정동) in total. Dong are also sub-divided into 13,787 tong (Hangul: 통; Hanja: 統), which are further divided into 102,796 ban in total.
DEMOGRAPHICS
Seoul proper is noted for its population density, which is almost twice that of New York and eight times greater than Rome. Its metropolitan area was the most densely populated in the OECD in Asia in 2012, and second worldwide after that of Paris. As of December 2013, the population was 10.14 million, in 2012, it was 10,442,426. As of the end of June 2011, 10.29 million Republic of Korea citizens lived in the city. This was a 24% decrease from the end of 2010. The population of Seoul has been dropping since the early 1990s, the reasons being the high costs of living and an aging population.
The number of foreigners living in Seoul is 255,501 in 2010 according to Seoul officials.[58] As of June 2011, 281,780 foreigners were located in Seoul. Of them, 186,631 foreigners (66%) were Chinese citizens of Korean ancestry. This was an 8.84% increase from the end of 2010 and a 12.85% increase from June 2010. The next largest group was Chinese citizens who are not of Korean ethnicity; 29,901 of them resided in Seoul. The next highest group consisted of the 9,999 United States citizens who were not of Korean ancestry. The next highest group were the Republic of China (Taiwan) citizens, at 8,717.
The two major religions in Seoul are Christianity and Buddhism. Other religions include Muism (indigenous religion) and Confucianism. Seoul is home to one of the world's largest Christians congregations, Yoido Full Gospel Church , which has around 830,000 members. Seoul is home to the world's largest modern university founded by a Buddhist Order, Dongguk University. Other Christian faiths like The Church of Jesus Christ of Latter-day Saints (Mormons) maintains a presence in the city.
ECONOMY
Seoul is the business and financial hub of South Korea. Although it accounts for only 0.6 percent of the nation's land area, 48.3 percent of South Korea's bank deposits were held in Seoul in 2003, and the city generated 23 percent of the country's GDP overall in 2012. In 2008 the Worldwide Centers of Commerce Index ranked Seoul No.9. The Global Financial Centres Index in 2015 listed Seoul as the 6th financially most competitive city in the world. The Economist Intelligence Unit ranked Seoul 15th in the list of "Overall 2025 City Competitiveness" regarding future competitiveness of cities.
MANUFACTURING
The traditional, labour-intensive manufacturing industries have been continuously replaced by information technology, electronics and assembly-type of industries; however, food and beverage production, as well as printing and publishing remained among the core industries. Major manufacturers are headquartered in the city, including Samsung, LG, Hyundai, Kia and SK. Notable food and beverage companies include Jinro, whose soju is the most sold alcoholic drink in the world, beating out Smirnoff vodka; top selling beer producers Hite (merged with Jinro) and Oriental Brewery. It also hosts food giants like Seoul Dairy Cooperative, Nongshim Group, Ottogi, CJ, Orion, Maeil Dairy, Namyang dairy and Lotte.
FINANCE
Seoul hosts large concentration of headquarters of International companies and banks, including 15 companies on fortune 500 list such as Samsung, LG and Hyundai. Most bank headquarters and the Korea Exchange are located in Yeouido (Yeoui island), which is often called "Korea's Wall Street" and has been serving as the financial center of the city since the 1980s. The Seoul international finance center & SIFC MALL, Hanhwa 63 building, the Hanhwa insurance company head office. Hanhwa is one of the three largest Korean insurance companies, along with Samsung Life and Gangnam & Kyob life insurance group.
COMMERCE
The largest wholesale and retail market in South Korea, the Dongdaemun Market, is located in Seoul. Myeongdong is a shopping and entertainment area in downtown Seoul with mid- to high-end stores, fashion boutiques and international brand outlets. The nearby Namdaemun Market, named after the Namdaemun Gate, is the oldest continually running market in Seoul.
Insadong is the cultural art market of Seoul, where traditional and modern Korean artworks, such as paintings, sculptures and calligraphy are sold. Hwanghak-dong Flea Market and Janganpyeong Antique Market also offer antique products. Some shops for local designers have opened in Samcheong-dong, where numerous small art galleries are located. Itaewon caters mainly to foreign tourists and American soldiers based in the city. The Gangnam district is one of the most affluent areas in Seoul and is noted for the fashionable and upscale Apgujeong-dong and Cheongdam-dong areas and the COEX Mall. Wholesale markets include Noryangjin Fisheries Wholesale Market and Garak Market.
The Yongsan Electronics Market is the largest electronics market in Asia. Electronics markets are Gangbyeon station metro line 2 Techno mart, ENTER6 MALL & Shindorim station Technomart mall complex.
Times Square is one of Seoul's largest shopping malls featuring the CGV Starium, the world's largest permanent 35 mm cinema screen.
KOREA WORLD TRADE CENTER COMPLEX which comprises COEX mall, congress center, 3 Inter-continental hotels, Business tower (Asem tower), Residence hotel,Casino and City airport terminal was established in 1988 Seoul Olympic . 2nd World trade trade center is planning at Seoul Olympic stadium complex as MICE HUB by Seoul city. Ex-Kepco head office building was purchased by Hyundai motor group with 9billion USD to build 115-storey Hyundai GBC & hotel complex until 2021. Now ex-kepco 25-storey building is under demolition.
ARCHITECTURE
The traditional heart of Seoul is the old Joseon Dynasty city, now the downtown area, where most palaces, government offices, corporate headquarters, hotels, and traditional markets are located. Cheonggyecheon, a stream that runs from west to east through the valley before emptying into the Han River, was for many years covered with concrete, but was recently restored by an urban revival project in 2005. Jongno street, meaning "Bell Street," has been a principal street and one of the earliest commercial steets of the city, on which one can find Bosingak, a pavilion containing a large bell. The bell signaled the different times of the day and controlled the four major gates to the city. North of downtown is Bukhan Mountain, and to the south is the smaller Namsan. Further south are the old suburbs, Yongsan District and Mapo District. Across the Han River are the newer and wealthier areas of Gangnam District, Seocho District and surrounding neighborhoods.
HISTORICAL ARCHITECTURE
Seoul has many historical and cultural landmarks. In Amsa-dong Prehistoric Settlement Site, Gangdong District, neolithic remains were excavated and accidentally discovered by a flood in 1925.
Urban and civil planning was a key concept when Seoul was first designed to serve as a capital in the late 14th century. The Joseon Dynasty built the "Five Grand Palaces" in Seoul – Changdeokgung, Changgyeonggung, Deoksugung, Gyeongbokgung and Gyeonghuigung – all of which are located in the district of Jongno District and Jung District. Among them, Changdeokgung was added to the UNESCO World Heritage List in 1997 as an "outstanding example of Far Eastern palace architecture and garden design". The main palace, Gyeongbokgung, underwent a large-scale restoration project. The palaces are considered exemplary architecture of the Joseon period. Beside the palaces, Unhyeongung is known for being the royal residence of Regent Daewongun, the father of Emperor Gojong at the end of the Joseon Dynasty.
Seoul has been surrounded by walls that were built to regulate visitors from other regions and protect the city in case of an invasion. Pungnap Toseong is a flat earthen wall built at the edge of the Han River which is widely believed to be the site of Wiryeseong. Mongchon Toseong (Hangul: 몽촌토성; Hanja: 蒙村土城) is another earthen wall built during the Baekje period which is now located inside the Olympic Park. The Fortress Wall of Seoul was built early in the Joseon Dynasty for protection of the city. After many centuries of destruction and rebuilding, approximately ⅔ of the wall remains, as well as six of the original eight gates. These gates include Sungnyemun and Heunginjimun, commonly known as Namdaemun (South Great Gate) and Dongdaemun (East Great Gate). Namdaemun was the oldest wooden gate until a 2008 arson attack, and was re-opened after complete restoration in 2013. Situated near the gates are the traditional markets and largest shopping center, Namdaemun Market and Dongdaemun Market.
There are also many buildings constructed with international styles in the late 19th and early 20th centuries. The Independence Gate was built in 1897 to inspire an independent spirit. Seoul Station was opened in 1900 as Gyeongseong Station.
MODERN ARCHITECTURE
Various high-rise office buildings and residential buildings, like the Gangnam Finance Center, the Tower Palace, N Seoul Tower and Jongno Tower, dominate the city's skyline. A series of new high rises are under construction, including the Lotte World Tower, scheduled to be completed by 2016. As of July 2016, and excluding the still unopened Lotte World Tower, the tallest building in the city is the 279-metre-high Three International Finance Center.
The World Trade Center Seoul, located in Gangnam District, hosts various expositions and conferences. Also in Gangnam District is the COEX Mall, a large indoor shopping and entertainment complex. Downstream from Gangnam District is Yeouido, an island that is home to the National Assembly, major broadcasting studios, and a number of large office buildings, as well as the Korea Finance Building and the Yoido Full Gospel Church. The Olympic Stadium, Olympic Park, and Lotte World are located in Songpa District, on the south side of the Han River, upstream from Gangnam District. Two new modern landmarks of Seoul are Dongdaemun Design Plaza & Park, designed by Zaha Hadid, and the new wave-shaped Seoul City Hall, by Yoo Kerl of iArc.
In 2010 Seoul was designated the World Design Capital for the year.
CULTURE
TECHNOLOGY
Seoul has a very technologically advanced infrastructure. It has the world's highest fibre-optic broadband penetration, resulting in the world's fastest internet connections with speeds up to 1 Gbps. Seoul provides free Wi-Fi access in outdoor spaces. This 47.7 billion won ($44 million) project will give residents and visitors Internet access at 10,430 parks, streets and other public places by 2015.
MUSEUMS
Seoul is home to 115 museums, including four national and nine official municipal museums. Amongst the city's national museum, The National Museum of Korea is the most representative of museums in not only Seoul but all of South Korea. Since its establishment in 1945, the museum has built a collection of 220,000 artifacts. In October 2005, the museum moved to a new building in Yongsan Family Park. The National Folk Museum is situated on the grounds of the Gyeongbokgung Palace in the district of Jongno District and uses replicas of historical objects to illustrate the folk history of the Korean people. The National Palace Museum of Korea is also located on the grounds of the Gyeongbokgung Palace. Finally, the Seoul branch of the National Museum of Modern and Contemporary Art, whose main museum is located in Gwacheon, opened in 2013, in Sogyeok-dong.
Bukchon Hanok Village and Namsangol Hanok Village are old residential districts consisting of hanok Korean traditional houses, parks, and museums that allows visitors to experience traditional Korean culture.
The War Memorial, one of nine municipal museums in Seoul, offers visitors an educational and emotional experience of various wars in which Korea was involved, including Korean War themes. The Seodaemun Prison is a former prison built during the Japanese occupation, and is currently used as a historic museum.The Seoul Museum of Art and Ilmin Museum of Art have preserved the appearance of the old building that is visually unique from the neighboring tall, modern buildings. The former is operated by Seoul City Council and sits adjacent to Gyeonghuigung Palace, a Joseon dynasty royal palace. Leeum, Samsung Museum of Art, is widely regarded as one of Seoul's largest private museum. For many Korean film lovers from all over the world, the Korean Film Archive is running the Korean Film Museum and Cinematheque KOFA in its main center located in Digital Media City (DMC), Sangam-dong. The Tteok & Kitchen Utensil Museum and Kimchi Field Museum provide information regarding Korean culinary history.
RELIGIOUS MONUMENTS
There are also religious buildings that take important roles in Korean society and politics. The Wongudan altar was a sacrificial place where Korean rulers held heavenly rituals since the Three Kingdoms period. Since the Joseon Dynasty adopted Confucianism as its national ideology in the 14th century, the state built many Confucian shrines. The descendants of the Joseon royal family still continue to hold ceremonies to commemorate ancestors at Jongmyo. It is the oldest royal Confucian shrine preserved and the ritual ceremonies continue a tradition established in the 14th century. Munmyo and Dongmyo were built during the same period. Although Buddhism was suppressed by the Joseon state, it has continued its existence. Jogyesa is the headquarters of the Jogye Order of Korean Buddhism. Hwagyesa and Bongeunsa are also major Buddhist temples in Seoul.
The Myeongdong Cathedral is a landmark of the Myeongdong, Jung District and the biggest Catholic church established in 1883. It is a symbol of Catholicism in Korea. It was also a focus for political dissent in the 1980s. In this way the Roman Catholic Church has a very strong influence in Korean society.
There are many Protestant churches in Seoul. The most numerous are Presbyterian, but there are also many Methodist, Baptist, and Lutheran churches. Yoido Full Gospel Church is a Pentecostal church affiliated with the Assemblies of God on Yeouido in Seoul. With approximately 830,000 members (2007), it is the largest Pentecostal Christian congregation in the world, which has been recognized by the Guinness Book of World Records.
FESTIVALS
In October 2012 KBS Hall in Seoul hosted major international music festivals – First ABU TV and Radio Song Festivals within frameworks of Asia-Pacific Broadcasting Union 49th General Assembly. Hi! Seoul Festival is a seasonal cultural festival held four times a year every spring, summer, autumn, and winter in Seoul, South Korea since 2003. It is based on the "Seoul Citizens' Day" held on every October since 1994 to commemorate the 600 years history of Seoul as the capital of the country. The festival is arranged under the Seoul Metropolitan Government. As of 2012, Seoul has hosted Ultra Music Festival Korea, an annual dance music festival that takes place on the 2nd weekend of June.
TRANSPORTATION
Seoul features one of the world's most advanced transportation infrastructures that is constantly under expansion. Its system dates back to the era of the Korean Empire, when the first streetcar lines were laid and a railroad linking Seoul and Incheon was completed. Seoul's most important streetcar line ran along Jongno until it was replaced by Line 1 of the subway system in the early 1970s. Other notable streets in downtown Seoul include Euljiro, Teheranno, Sejongno, Chungmuro, Yulgongno, and Toegyero. There are nine major subway lines stretching for more than 250 km, with one additional line planned. As of 2010, 25% of the population has a commute time of an hour or more.
BUS
Seoul's bus system is operated by the Seoul Metropolitan Government (S.M.G.), with four primary bus configurations available servicing most of the city. Seoul has many large intercity/express bus terminals. These buses connect Seoul with cities throughout South Korea. The Seoul Express Bus Terminal, Central City Terminal and Seoul Nambu Terminal are located in the district of Seocho District. In addition, East Seoul Bus Terminal in Gwangjin District and Sangbong Terminal in Jungnang District operate in the east of the city.
SUBWAY
Seoul has a comprehensive urban railway network that interconnects every district of the city and the surrounding areas. With more than 8 million passengers per day, Seoul has one of the busiest subway systems in the world. The Seoul Metropolitan Subway has 19 total lines which serve Seoul, Incheon, Gyeonggi province, western Gangwon province, and northern Chungnam province. In addition, in order to cope with the various modes of transport, Seoul's metropolitan government employs several mathematicians to coordinate the subway, bus, and traffic schedules into one timetable. The various lines are run by Korail, Seoul Metro, Seoul Metropolitan Rapid Transit Corporation, NeoTrans Co. Ltd., AREX, and Seoul Metro Line 9 Corporation.
TRAIN
Seoul is connected to every major city in South Korea by rail. Seoul is also linked to most major South Korean cities by the KTX high-speed train, which has a normal operation speed of more than 300 km/h. Major railroad stations include:
Seoul Station, Yongsan District: Gyeongbu line (KTX/Saemaul/Mugunghwa-ho), Gyeongui line (Saemaul/Commuter)
Yongsan Station, Yongsan District: Honam line (KTX/Saemaul/Mugunghwa), Jeolla/Janghang lines (Saemaul/Mugunghwa)
Yeongdeungpo Station, Yeongdeungpo District: Gyeongbu/Honam/Janghang lines (Saemaul/Mugunghwa)
Cheongnyangni Station, Dongdaemun District: Gyeongchun/Jungang/Yeongdong/Taebaek lines (Mugunghwa)
In addition, Suseo Station,in Gangnam District, is scheduled to open in late 2016, and offer KTX service on the newly built Suseo High Speed Railway.
AIRPORTS
Two international airports serve Seoul. Gimpo International Airport, formerly in Gimpo but annexed to Seoul in 1963, was for many years (since its original construction during the Korean War) the only international airport serving Seoul. Other domestic airports were also built around the time of the war, including Yeouido.
When it opened in March 2001, Incheon International Airport on Yeongjong island in Incheon changed the role of Gimpo Airport significantly. Incheon is now responsible for almost all international flights and some domestic flights, while Gimpo serves only domestic flights with the exception of flights to Haneda Airport in Tokyo, Osaka Kansai International Airport, Taipei Songshan Airport in Taipei, Hongqiao Airport in Shanghai, and Beijing Capital International Airport in Beijing. This has led to a significant drop in flights from Gimpo Airport, though it remains one of South Korea's busiest airports.
Meanwhile, Incheon International Airport has become, along with Hong Kong, a major transportation center for East Asia.
Incheon and Gimpo are linked to Seoul by highways, and to each other by the Incheon International Airport Railroad, which is also linked to Incheon line #1. Gimpo is also linked by subway (line No. 5 and #9). The Incheon International Airport Railroad, connecting the airport directly to Seoul Station in central Seoul, was recently opened. Shuttle buses also transfer passengers between Incheon and Gimpo airports.
CYCLING
Cycling is becoming increasingly popular in Seoul and in the entire country. Both banks of the Han River have cycling paths that run all the way across the city along the river. In addition, Seoul introduced in 2015 a bicycle-sharing system named Ddareungi.
EDUCATION
UNICERSITIES
Seoul is home to the majority of South Korea's most prestigious universities, including Seoul National University, Yonsei University, Korea University, Sungkyunkwan University, Sogang University, Hanyang University, Chung-Ang University, Ewha Womans University, Hankuk University of Foreign Studies, Hongik University, Kyung Hee University, Soongsil University, Sookmyung Women's University, Korea Military Academy, and the University of Seoul.
SECONDARY EDUCATION
Education from grades 1–12 is compulsory. Students spend six years in elementary school, three years in middle school, and three years in high school. Secondary schools generally require that the students wear uniforms. There is an exit exam for graduating from high school and many students proceeding to the university level are required to take the College Scholastic Ability Test that is held every November. Although there is a test for non-high school graduates, called school qualification exam, most of Koreans take the test
Seoul is home to various specialized schools, including three science high schools (Hansung Science High School, Sejong Science High School and Seoul Science High School), and six foreign language High Schools (Daewon Foreign Language High School, Daeil Foreign Language High School, Ewha Girls' Foreign Language High School, Hanyoung Foreign Language High School, Myungduk Foreign Language High School and Seoul Foreign Language High School). Seoul Metropolitan Office of Education comprises 235 College-Preparatory High Schools, 80 Vocational Schools, 377 Middle Schools, and 33 Special Education Schools as of 2009.
INTERNATIONAL RELATIONS

WIKIPEDIA

Voronezh is a city and the administrative centre of Voronezh Oblast in southwestern Russia straddling the Voronezh River, located 12 kilometers (7.5 mi) from where it flows into the Don River. The city sits on the Southeastern Railway, which connects western Russia with the Urals and Siberia, the Caucasus and Ukraine, and the M4 highway (Moscow–Voronezh–Rostov-on-Don–Novorossiysk). In recent years the city has experienced rapid population growth, rising in 2021 to 1,057,681, up from 889,680 recorded in the 2010 Census, making it the 14th-most populous city in the country.
History
The first chronicle references to the word "Voronezh" are dated 1177, when the Ryazan prince Yaropolk, having lost the battle, fled "to Voronozh" and there was moving "from town to town". Modern data of archeology and history interpret Voronezh as a geographical region, which included the Voronezh river (tributary of the Don) and a number of settlements. In the lower reaches of the river, a unique Slavic town-planning complex of the 8th – early 11th century was discovered, which covered the territory of the present city of Voronezh and its environs (about 42 km long, about 13 forts and many unfortified villages). By the 12th – 13th centuries, most of the old towns were desolate, but new settlements appeared upstream, closer to Ryazan.
For many years, the hypothesis of the Soviet historian Vladimir Zagorovsky dominated: he produced the toponym "Voronezh" from the hypothetical Slavic personal name Voroneg. This man allegedly gave the name of a small town in the Chernigov Principality (now the village of Voronezh in Ukraine). Later, in the 11th or 12th century, the settlers were able to "transfer" this name to the Don region, where they named the second city Voronezh, and the river got its name from the city. However, now many researchers criticize the hypothesis, since in reality neither the name of Voroneg nor the second city was revealed, and usually the names of Russian cities repeated the names of the rivers, but not vice versa.
The linguistic comparative analysis of the name "Voronezh" was carried out by the Khovansky Foundation in 2009. There is an indication of the place names of many countries in Eurasia, which may partly be not only similar in sound, but also united by common Indo-European languages: Varanasi, Varna, Verona, Brno, etc.
A comprehensive scientific analysis was conducted in 2015–2016 by the historian Pavel Popov. His conclusion: "Voronezh" is a probable Slavic macrotoponym associated with outstanding signs of nature, has a root voron- (from the proto-Slavic vorn) in the meaning of "black, dark" and the suffix -ezh (-azh, -ozh). It was not “transferred” and in the 8th - 9th centuries it marked a vast territory covered with black forests (oak forests) - from the mouth of the Voronezh river to the Voronozhsky annalistic forests in the middle and upper reaches of the river, and in the west to the Don (many forests were cut down). The historian believes that the main "city" of the early town-planning complex could repeat the name of the region – Voronezh. Now the hillfort is located in the administrative part of the modern city, in the Voronezh upland oak forest. This is one of Europe's largest ancient Slavic hillforts, the area of which – more than 9 hectares – 13 times the area of the main settlement in Kyiv before the baptism of Rus.
In it is assumed that the word "Voronezh" means bluing - a technique to increase the corrosion resistance of iron products. This explanation fits well with the proximity to the ancient city of Voronezh of a large iron deposit and the city of Stary Oskol.
Folk etymology claims the name comes from combining the Russian words for raven (ворон) and hedgehog (еж) into Воронеж. According to this explanation two Slavic tribes named after the animals used this combination to name the river which later in turn provided the name for a settlement. There is not believed to be any scientific support for this explanation.
In the 16th century, the Middle Don basin, including the Voronezh river, was gradually conquered by Muscovy from the Nogai Horde (a successor state of the Golden Horde), and the current city of Voronezh was established in 1585 by Feodor I as a fort protecting the Muravsky Trail trade route against the slave raids of the Nogai and Crimean Tatars. The city was named after the river.
17th to 19th centuries
In the 17th century, Voronezh gradually evolved into a sizable town. Weronecz is shown on the Worona river in Resania in Joan Blaeu's map of 1645. Peter the Great built a dockyard in Voronezh where the Azov Flotilla was constructed for the Azov campaigns in 1695 and 1696. This fleet, the first ever built in Russia, included the first Russian ship of the line, Goto Predestinatsia. The Orthodox diocese of Voronezh was instituted in 1682 and its first bishop, Mitrofan of Voronezh, was later proclaimed the town's patron saint.
Owing to the Voronezh Admiralty Wharf, for a short time, Voronezh became the largest city of South Russia and the economic center of a large and fertile region. In 1711, it was made the seat of the Azov Governorate, which eventually morphed into the Voronezh Governorate.
In the 19th century, Voronezh was a center of the Central Black Earth Region. Manufacturing industry (mills, tallow-melting, butter-making, soap, leather, and other works) as well as bread, cattle, suet, and the hair trade developed in the town. A railway connected Voronezh with Moscow in 1868 and Rostov-on-Don in 1871.
20th century
World War II
During World War II, Voronezh was the scene of fierce fighting between Soviet and combined Axis troops. The Germans used it as a staging area for their attack on Stalingrad, and made it a key crossing point on the Don River. In June 1941, two BM-13 (Fighting machine #13 Katyusha) artillery installations were built at the Voronezh excavator factory. In July, the construction of Katyushas was rationalized so that their manufacture became easier and the time of volley repetition was shortened from five minutes to fifteen seconds. More than 300 BM-13 units manufactured in Voronezh were used in a counterattack near Moscow in December 1941. In October 22, 1941, the advance of the German troops prompted the establishment of a defense committee in the city. On November 7, 1941, there was a troop parade, devoted to the anniversary of the October Revolution. Only three such parades were organized that year: in Moscow, Kuybyshev, and Voronezh. In late June 1942, the city was attacked by German and Hungarian forces. In response, Soviet forces formed the Voronezh Front. By July 6, the German army occupied the western river-bank suburbs before being subjected to a fierce Soviet counter-attack. By July 24 the frontline had stabilised along the Voronezh River as the German forces continued southeast into the Great Bend of the Don. The attack on Voronezh represented the first phase of the German Army's 1942 campaign in the Soviet Union, codenamed Case Blue.
Until January 25, 1943, parts of the Second German Army and the Second Hungarian Army occupied the western part of Voronezh. During Operation Little Saturn, the Ostrogozhsk–Rossosh Offensive, and the Voronezhsko-Kastornenskoy Offensive, the Voronezh Front exacted heavy casualties on Axis forces. On January 25, 1943, Voronezh was liberated after ten days of combat. During the war the city was almost completely ruined, with 92% of all buildings destroyed.
Post-war
By 1950, Voronezh had been rebuilt. Most buildings and historical monuments were repaired. It was also the location of a prestigious Suvorov Military School, a boarding school for young boys who were considered to be prospective military officers, many of whom had been orphaned by war.
In 1950–1960, new factories were established: a tire factory, a machine-tool factory, a factory of heavy mechanical pressing, and others. In 1968, Serial production of the Tupolev Tu-144 supersonic plane was established at the Voronezh Aviation factory. In October 1977, the first Soviet domestic wide-body plane, Ilyushin Il-86, was built there.
In 1989, TASS published details of an alleged UFO landing in the city's park and purported encounters with extraterrestrial beings reported by a number of children. A Russian scientist that was cited in initial TASS reports later told the Associated Press that he was misquoted, cautioning, "Don't believe all you hear from TASS," and "We never gave them part of what they published", and a TASS correspondent admitted the possibility that some "make-believe" had been added to the TASS story, saying, "I think there is a certain portion of truth, but it is not excluded that there is also fantasizing".
21st century
From 10 to 17 September 2011, Voronezh celebrated its 425th anniversary. The anniversary of the city was given the status of a federal scale celebration that helped attract large investments from the federal and regional budgets for development.
On December 17, 2012, Voronezh became the fifteenth city in Russia with a population of over one million people.
Today Voronezh is the economic, industrial, cultural, and scientific center of the Central Black Earth Region. As part of the annual tradition in the Russian city of Voronezh, every winter the main city square is thematically drawn around a classic literature. In 2020, the city was decorated using the motifs from Pyotr Ilyich Tchaikovsky's The Nutcracker. In the year of 2021, the architects drew inspiration from Hans Christian Andersen's fairy tale The Snow Queen as well as the animation classic The Snow Queen from the Soviet Union. The fairy tale replica city will feature the houses of Kai and Gerda, the palace of the snow queen, an ice rink, and illumination.
In June 2023, during the Wagner Group rebellion, forces of the Wagner Group claimed to have taken control of military facilities in the city. Later they were confirmed to have taken the city itself.

Geography
Urban layout
Information about the original urban layout of Voronezh is contained in the "Patrol Book" of 1615. At that time, the city fortress was logged and located on the banks of the Voronezh River. In plan, it was an irregular quadrangle with a perimeter of about 238 meter. inside it, due to lack of space, there was no housing or siege yards, and even the cathedral church was supposed to be taken out. However, at this small fortress there was a large garrison - 666 households of service people. These courtyards were reliably protected by the second line of fortifications by a standing prison on taras with 25 towers covered with earth; behind the prison was a moat, and beyond the moat there were stakes. Voronezh was a typical military settlement (ostrog). In the city prison there were only settlements of military men: Streletskaya, Kazachya, Belomestnaya atamanskaya, Zatinnaya and Pushkarskaya. The posad population received the territory between the ostrog and the river, where the Monastyrskaya settlements (at the Assumption Monastery) was formed. Subsequently, the Yamnaya Sloboda was added to them, and on the other side of the fort, on the Chizhovka Mountain, the Chizhovskaya Sloboda of archers and Cossacks appeared. As a result, the Voronezh settlements surrounded the fortress in a ring. The location of the parish churches emphasized this ring-like and even distribution of settlements: the Ilyinsky Church of the Streletskaya Sloboda, the Pyatnitskaya Cossack and Pokrovskaya Belomestnaya were brought out to the passage towers of the prison. The Nikolskaya Church of the Streletskaya Sloboda was located near the marketplace (and, accordingly, the front facade of the fortress), and the paired ensemble of the Rozhdestvenskaya and Georgievskaya churches of the Cossack Sloboda marked the main street of the city, going from the Cossack Gate to the fortress tower.
Climate
Voronezh experiences a humid continental climate (Köppen: Dfb) with long, cold winters and short, warm summers.

Voronezh also hosts the Voronezh Malshevo air force base in the southwest of the city, which, according to a Natural Resources Defense Council report, houses nuclear bombers.[citation needed]
Rail
Since 1868, there is a railway connection between Voronezh and Moscow. Rail services form a part of the South Eastern Railway of the Russian Railways. Destinations served direct from Voronezh include Moscow, Kyiv, Kursk, Novorossiysk, Sochi, and Tambov. The main train station is called Voronezh-1 railway station and is located in the center of the city.

Religion
Annunciation Orthodox Cathedral in Voronezh
Orthodox Christianity is the predominant religion in Voronezh.[citation needed] There is an Orthodox Jewish community in Voronezh, with a synagogue located on Stankevicha Street.
In 1682, the Voronezh diocese was formed to fight the schismatics. Its first head was Bishop Mitrofan (1623-1703) at the age of 58. Under him, the construction began on the new Annunciation Cathedral to replace the old one. In 1832, Mitrofan was canonized by the Russian Orthodox Church.
In the 1990s, many Orthodox churches were returned to the diocese. Their restoration was continued. In 2009, instead of the lost one, a new Annunciation Cathedral was built with a monument to St. Mitrofan erected next to it.

No Surrealist exhibition would be complete without something by Dutch mathematician Maurits Cornelis Escher! I'd like to think God gave Brother Martin a helping hand, don't you?
Using the UWA here was probably a little overzealous with the D90's high ISO capabilities, but I thought, 'what the heck', and went for it. It took a couple of tries, but after I timed this scene (the teacher completely freezes for a moment as the scene resets while he raises his arm), I nailed it as best as I could.
Pythagoras promoted the idea of a rational universe where number was the foundation for all existence
A sign marking where Mathematician George Boole lived and is said to have founded a School. At 3 Pottergate, in Lincoln, Lincolnshire.
Although he was recognised as a genius in his own lifetime, it was not until almost a century later that the far-reaching implications of Boole’s work would become apparent. An American electronics engineer named Claude Shannon realised Boole’s logic could be applied in producing electrical circuits: a discovery that started the digital revolution. Today even the most advanced computers and smart devices still depend on Boolean logic.
Boole, the son of John Boole Sr, a shoemaker and Mary Ann Joyce, was born on November 2nd 1815, at 34 Silver Street, Lincoln - his home no longer exists but was near the former The Constitution Club.
He was christened at St Swithins Church and attended the church in his early life; the minister there encouraged him in his mathematics, lending him a book on differential calculus. A plaque stands in Boole's memory on the site where the church stood when he attended, further along St Swithins Square than the current church building.
He had a primary school education, and received lessons from his father, but had little further formal and academic teaching. William Brooke, a bookseller in Lincoln, may have helped him with Latin, which he may also have learned at the school of Thomas Bainbridge. He was self-taught in modern languages.
Boole opened his own school in 1834 very close to St Swithins Church, on Free School Lane when he was just aged 19. Also nearby was Lincoln Mechanics Institute of which Boole's father was a founding member and where Boole lectured - in the old Grammar School, the Greyfriars.
Boole later founded a school on Pottergate near Lincoln Cathedral which is also where his home is said to have been. It was at this school that Boole conducted his last teaching in Lincoln and where he won the Gold Medal from the Royal Society, in 1844. A plaque is found at 3 Pottergate in Boole's memory.
Boole was keen to further his skills in higher mathematics and, with limited opportunities in Lincoln, took up a professorship at Queen's College Cork, Ireland, moving there in 1849. It was in Cork that he met his wife and started a family, eventually having five daughters. Boole ended his days here on December 8th 1864, dying prematurely aged only 49.
Friends of Boole still in Lincoln raised funds to create a memorial for the mathematician in Lincoln Cathedral: The Teaching Window. The stained glass window, found in the fourth window of the north wall of the cathedral, depicts the calling of Samuel, his favourite Bible passage, at the request of his widow.

When he was 15 years old, he obtained a copy of George Shoobridge Carr’s Synopsis of Elementary Results in Pure and Applied Mathematics, 2 vol. (1880–86). This collection of thousands of theorems, many presented with only the briefest of proofs and with no material newer than 1860, aroused his genius. Having verified the results in Carr’s book, Ramanujan went beyond it, developing his own theorems and ideas. In 1903 he secured a scholarship to the University of Madras but lost it the following year because he neglected all other studies in pursuit of mathematics.
Ramanujan continued his work, without employment and living in the poorest circumstances. After marrying in 1909 he began a search for permanent employment that culminated in an interview with a government official, Ramachandra Rao. Impressed by Ramanujan’s mathematical prowess, Rao supported his research for a time, but Ramanujan, unwilling to exist on charity, obtained a clerical post with the Madras Port Trust.
In 1911 Ramanujan published the first of his papers in the Journal of the Indian Mathematical Society. His genius slowly gained recognition, and in 1913 he began a correspondence with the British mathematician Godfrey H. Hardy that led to a special scholarship from the University of Madras and a grant from Trinity College, Cambridge. Overcoming his religious objections, Ramanujan traveled to England in 1914, where Hardy tutored him and collaborated with him in some research.
Ramanujan’s knowledge of mathematics (most of which he had worked out for himself) was startling. Although he was almost completely unaware of modern developments in mathematics, his mastery of continued fractions was unequaled by any living mathematician. He worked out the Riemann series, the elliptic integrals, hypergeometric series, the functional equations of the zeta function, and his own theory of divergent series, in which he found a value for the sum of such series using a technique he invented that came to be called Ramanujan summation. On the other hand, he knew nothing of doubly periodic functions, the classical theory of quadratic forms, or Cauchy’s theorem, and he had only the most nebulous idea of what constitutes a mathematical proof. Though brilliant, many of his theorems on the theory of prime numbers were wrong.
In England Ramanujan made further advances, especially in the partition of numbers (the number of ways that a positive integer can be expressed as the sum of positive integers; e.g., 4 can be expressed as 4, 3 + 1, 2 + 2, 2 + 1 + 1, and 1 + 1 + 1 + 1).
His papers were published in English and European journals, and in 1918 he was elected to the Royal Society of London. In 1917 Ramanujan had contracted tuberculosis, but his condition improved sufficiently for him to return to India in 1919. He died the following year, generally unknown to the world at large but recognized by mathematicians as a phenomenal genius, without peer since Leonhard Euler (1707–83) and Carl Jacobi (1804–51).
Ramanujan left behind three notebooks and a sheaf of pages (also called the “lost notebook”) containing many unpublished results that mathematicians continued to verify long after his death.

Manchester saw officers and staff from 17 police forces and policing organisations walking as Police with Pride in the Manchester Pride Parade on Saturday 25th August.
Officers and staff from across the country lead the parade as Greater Manchester Police (GMP) celebrated its 10th anniversary of taking part in the parade.
GMP mascots Constable Cub and Pippa the Panda were also there to join in the celebrations.
The parade entry was organised by Police with Pride, which consists of Lesbian, Gay, Bisexual and Transgender (LGBT) representatives from forces across the North West who organise and promote the event nationally.
Darrelle Lynch, coordinator of GMP's Lesbian and Gay Staff Affiliation (LAGSA), said: "This year has seen another fantastic response, with an increase in the numbers taking part and the number of police forces represented. It shows that confidence is increasing among our LGBT staff, who walked through the streets of Manchester proudly.
"Taking part in Pride will hopefully send out a strong message to LGBT communities that you can be gay or trans and work for the police. It should also give them confidence to talk to the police and report crimes in the knowledge that they will be taken seriously. We are committed to erasing hate crime in our communities, and anyone who has been targeted because of their sexual orientation or gender identity should always tell us, as we will take action."
Chief Constable Sir Peter Fahy said: "This year's parade is dedicated to the code-breaking mathematician and computer scientist Alan Turing, whose work during the Second World War was vital, and whose sexuality resulted in a criminal prosecution in 1952. It's worth remembering how far we have come, and that it is totally unacceptable for people to be treated in this way. Manchester Pride is a very important event for GMP and I am especially proud that our officers and staff, myself included, lead the parade this year."
The GMP float for this year's parade displayed banners encouraging people to report hate crime, and explaining that the offence covers five main areas - disability, gender-identity, race, religion or faith and sexual orientation.

You should call 101, the new national non-emergency number, to report crime and other concerns that do not require an emergency response.
Always call 999 in an emergency, such as when a crime is in progress, violence is being used or threatened or where there is danger to life.
You can also call anonymously with information about crime to Crimestoppers on 0800 555 111. Crimestoppers is an independent charity who will not want your name, just your information. Your call will not be traced or recorded and you do not have to go to court or give a statement.

Ansel Adams used the golden ratio in his photography too:

The Fibonacci Numbers are closely related to the golden ratio, and thus they also play a prominent role in exalted natural and artistic compositions!
I'm working on a far deeper book titled The Golden Ratio Number for Photographers. :)
The famous mathematician Jacob Bernoulli wrote:
The (golden spiral) may be used as a symbol, either of fortitude and constancy in adversity, or of the human body, which after all its changes, even after death, will be restored to its exact and perfect self.
Engraved upon Jacob’s tombstone is a spiral alongside the words, "Eadem Mutata Resurgo," meaning "Though changed, I shall rise again." And so it is that within the Golden Ratio Principle, the golden harmonies rise yet again.
The golden ratio is oft known as the divine cut, the golden cut, the divine proportion, the golden number, and PHI for the name of the architect of the Parthenon Phidias. It has exalted classical art on down through the millennia and it can exalt your art too!
Ask me anything about the golden ratio! :) I will do my best to answer!!

Dr. Elliot McGucken's Golden Ratio Principle: The Golden Number Ratio Principle: Dr. E’s Golden Ratio Principle: The golden ratio exalts beauty because the number is a characteristic of the mathematically and physically most efficient manners of growth and distribution, on both evolutionary and purely physical levels. The golden ratio ensures that the proportions and structure of that which came before provide the proportions and structure of that which comes after. Robust, ordered growth is naturally associated with health and beauty, and thus we evolved to perceive the golden ratio harmonies as inherently beautiful, as we saw and felt their presence in all vital growth and life—in the salient features and proportions of humans and nature alike, from the distribution of our facial features and bones to the arrangements of petals, leaves, and sunflowers seeds. As ratios between Fibonacci Numbers offer the closest whole-number approximations to the golden ratio, and as seeds, cells, leaves, bones, and other physical entities appear in whole numbers, the Fibonacci Numbers oft appear in nature’s elements as “growth’s numbers.” From the dawn of time, humanity sought to salute their gods in art and temples exalting the same proportion by which all their vital sustenance and they themselves had been created—the golden ratio. the golden number, rectangle, and spiral!
The combination of increasingly complex high-risk financial instruments (unknown, under-acknowledged, under-estimated and/or misunderstood by public and private policy sector workers at all levels of governance) and a thriving culture of testosterone-driven traders with their hands firmly on the throttle of oil-dependent muscle vehicles, flooring-it on shared virtual highways with silently condoned (albeit) unwritten permission and even enthusiastic encouragement to exceed safe speed limits, the exponential growth in wealth of the upper quintile of the upper quintile accompanied by the exponential increase in poverty of the lower quintile of the lower quintile, the global expansion and implementation of the belief-system based on unfettered, self-regulated market political economies (loosely called market liberalism although best-served by political conservatism) promulgated around the planet through mass media content packaged to sell imagery of the invisible hand of the market as the right hand of the new secular god surrounded by soldiers of the user-pay, private-is-better, blame-the-poor, monetize-everything, blame-the-ill, social-justice-vs-economic-efficiency, base-minumum-wage-on-pin-money-workers, minimum-government, trickle-down-affect, legal-but-not-ethical, group-think-culture led by the Triad of Mises-Friedman-Hayek has led to market chaos that is not theoretical but Really Real.
According to Dan Mitchell's article Trading on Testosterone" in the New York Times, "Movements in financial markets are correlated to the levels of hormones in the bodies of male traders, according to a study by two researchers from the University of Cambridge."
The Adobe Photoshop image was created by adding the Suit to the bull and layering my own mortgage meltdown digitage with the article's illustration by Alex Eben Meyer in the New York Times. I saved this as a transparent .png file. (I am unsure of the licensing for the NYT image.) [1]
This is twisted curve in the winding road of ancient arguments that prohibited participation of hormone-driven women (emotional versus logical, intuitive versus deductive, feelings versus reason) in pivotal positions of decision-making.
Does this mean the invisible hand of the market should be wearing a glove? Should the use of Viagra be monitored on the trading floor?

I notice a lot of people bypass this and simply thank oceanflynn or Maureen Flynn-Burhoe which is fine for me because Google makes the link. It wouldn't if your name was not as easily identified by Google. And this method is not really Flickr-friendly.
However, Flickr has its own set of rules which requires that the live link to the Flickr-hosted image. This also accesses the accompanying explanatory text which describes how I added my own original mashups as well as remixing and reusing some of the work of other artists.
If you follow my links to the NYT's article you can see where the bull and bear originate. I put the bull in a Wall Street suit and tie and added my own original Adobe Photoshop image which was quite timely and involved. When you crop to include only the bear and bull, it is possible that it borrows too heavily from the original NYT's article illustration.

Inside Parma Cathedral day 4 of our Cosmos tour, October 3, 2012. After a nights stay in Montecatini we are now heading to the Venica area. We arrived in Montecatini in the dark and left in the dark so got no shots there.
Parma Cathedral (Duomo) is a cathedral church in Parma, Emilia-Romagna (Italy). It is an important Italian Romanesque cathedral: the dome, in particular, is decorated by a highly influential illusionistic fresco by Renaissance painter Antonio da Correggio.
The construction was begun in 1059 by bishop Cadalo, later antipope with the name of Honorius II, and was consecrated by Paschal II in 1106. A basilica existed probably in the 6th century, but was later abandoned; another church had been consecrated in the rear part of the preceding one in the 9th century by the count-bishop Guibodo. The new church was heavily damaged by an earthquake in 1117 and had to be restored. Of the original building, remains can be seen in the presbytery, the transept, the choir and the apses, and in some sculpture fragments. The wide façade was completed in 1178: it has three loggia floors and three portals, whose doors were sculpted by Luchino Bianchino in 1494. Between the central and the right doors is the tomb of the mathematician Biagio Pelacani, who died in 1416.
The Gothic belfry was added later, in 1284-1294: a twin construction on the left side had been conceived, but it was never begun. Beside the Cathedral lies the octagonal Baptistry of Parma.

One of the most popular and unusual sculptures in Krakow old town, is that of two gesticulating men seated on the wooden bench. These are the Polish mathematicians Stefan Banach and Otto M. Nikodym, who in 1916 were joined by mathematician Hugo Steinhaus, in a discussion of complex mathematical problems.
My wife and I were in a co-op we belong to, researching some cycling gear for an upcoming trip. She had a bit more research to do but I was finished and said I would wait outside. I saw this man sitting on a ledge across the street behind a streetcar stop and crossed the street, hoping to meet him. His abundant hair was the first thing I noticed about him but as I got closer I saw he had a very attractive and friendly face too. He was sitting with a dark panel behind him and just as I was trying to figure out how I would photograph him without “losing” his hair against the background, he got up and walked my way.
I introduced myself and he seemed happy that I spoke. I told him of my project and he said “Of course. It sounds great. What do you want me to do?” Wow. He was the second stranger in a row today who didn’t seem to hesitate for a moment when invited to the project. We shook hands. Meet Amar.
I noticed a smooth stone wall just a couple of steps away, almost but not quite behind the streetcar stop and thought it would be neutral and contrasting behind his hair. I pointed to it and then explained I wanted him not quite against the wall but a couple of steps into the sidewalk and explained I would stand near the curb and wait for breaks in the pedestrian traffic to make the photos. We proceeded and after three or four photos I was satisfied and we looked at them together. Amar said “Are you sure you got what you need?” I thanked him and said I had what I needed.
Amar is 27 and came to Canada 10 years ago from the island kingdom of Bahrain in the Persian Gulf. He is a mathematician. I asked if he was working and he explained he had worked for several years as an actuary but found it had become boring so he quit and was considering his next move. I joked “So, you got tired of calculating when people are going to die?” He laughed and said “Pretty much.” “What is your dream job as a mathematician?” I asked. “Gosh” he said, “I wish I knew. I’ll tell you when I figure it out.”
Amar was on his way to the market when we met and said “So, you can just say you caught me in transit today.” When I asked if he had any thoughts to share with the group he thought for a moment and said “Just something about how impermanent life is.” He went on to say “That may seem a strange thought when you have just captured a photo which is permanent.” I said “Well, it’s permanent, but it’s a tiny moment of passing time.” We agreed.
I told Amar how much I appreciated his joining my project and he commented on what a great project it is. “It’s obviously about a lot more than photography, isn’t it? It’s got a humanitarian aspect and is about connections.” I was impressed by his deeper understanding of the project's meaning. “Exactly” I said. “It’s also about trust. It takes a lot of trust to agree to a stranger walking up and starting a conversation and wanting to photograph you.” Amar said “Yes… and we need a lot more trust in the world. It’s something that was in particularly short supply where I come from.”
I found Amar to be a very open and thoughtful man and felt lucky to have met him today. We exchanged contact information and wished each other well as we went our separate ways.
Thank you Amar for participating in 100 Strangers. You are Stranger #544 in Round 6 of my project. It is a particular pleasure to meet someone like you – someone who quickly grasps the deeper level of this great project.

So that is taken during a math class ;) Me and Irinka :)
Isn't it obvious how much she "loves" maths and how much I am "not" crazy about it? xaxaxa :D
so here you can see how would your notebook look like if you are a mathematician and you are absent-minded!!! :D xaxa
Artistic chaos :p
Well... gotta say I have an exam in math tomorrow ;) hehe wish me luck! ;) Though I am good at it ;) I still need little drops of luck! ;)
Spaceflight (or space flight) is ballistic flight into or through outer space. Spaceflight can occur with spacecraft with or without humans on board. Yuri Gagarin of the Soviet Union was the first human to conduct a spaceflight. Examples of human spaceflight include the U.S. Apollo Moon landing and Space Shuttle programs and the Russian Soyuz program, as well as the ongoing International Space Station. Examples of unmanned spaceflight include space probes that leave Earth orbit, as well as satellites in orbit around Earth, such as communications satellites. These operate either by telerobotic control or are fully autonomous.
Spaceflight is used in space exploration, and also in commercial activities like space tourism and satellite telecommunications. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other Earth observation satellites.
A spaceflight typically begins with a rocket launch, which provides the initial thrust to overcome the force of gravity and propels the spacecraft from the surface of the Earth. Once in space, the motion of a spacecraft – both when unpropelled and when under propulsion – is covered by the area of study called astrodynamics. Some spacecraft remain in space indefinitely, some disintegrate during atmospheric reentry, and others reach a planetary or lunar surface for landing or impact.
History
Main articles: History of spaceflight and Timeline of spaceflight
Tsiolkovsky, early space theorist
The first theoretical proposal of space travel using rockets was published by Scottish astronomer and mathematician William Leitch, in an 1861 essay "A Journey Through Space".[1] More well-known (though not widely outside Russia) is Konstantin Tsiolkovsky's work, "Исследование мировых пространств реактивными приборами" (The Exploration of Cosmic Space by Means of Reaction Devices), published in 1903.
Spaceflight became an engineering possibility with the work of Robert H. Goddard's publication in 1919 of his paper A Method of Reaching Extreme Altitudes. His application of the de Laval nozzle to liquid fuel rockets improved efficiency enough for interplanetary travel to become possible. He also proved in the laboratory that rockets would work in the vacuum of space;[specify] nonetheless, his work was not taken seriously by the public. His attempt to secure an Army contract for a rocket-propelled weapon in the first World War was defeated by the November 11, 1918 armistice with Germany. Working with private financial support, he was the first to launch a liquid-fueled rocket in 1926. Goddard's paper was highly influential on Hermann Oberth, who in turn influenced Wernher von Braun. Von Braun became the first to produce modern rockets as guided weapons, employed by Adolf Hitler. Von Braun's V-2 was the first rocket to reach space, at an altitude of 189 kilometers (102 nautical miles) on a June 1944 test flight.[2]
Tsiolkovsky's rocketry work was not fully appreciated in his lifetime, but he influenced Sergey Korolev, who became the Soviet Union's chief rocket designer under Joseph Stalin, to develop intercontinental ballistic missiles to carry nuclear weapons as a counter measure to United States bomber planes. Derivatives of Korolev's R-7 Semyorka missiles were used to launch the world's first artificial Earth satellite, Sputnik 1, on October 4, 1957, and later the first human to orbit the Earth, Yuri Gagarin in Vostok 1, on April 12, 1961.[3]
At the end of World War II, von Braun and most of his rocket team surrendered to the United States, and were expatriated to work on American missiles at what became the Army Ballistic Missile Agency. This work on missiles such as Juno I and Atlas enabled launch of the first US satellite Explorer 1 on February 1, 1958, and the first American in orbit, John Glenn in Friendship 7 on February 20, 1962. As director of the Marshall Space Flight Center, Von Braun oversaw development of a larger class of rocket called Saturn, which allowed the US to send the first two humans, Neil Armstrong and Buzz Aldrin, to the Moon and back on Apollo 11 in July 1969. Over the same period, the Soviet Union secretly tried but failed to develop the N1 rocket to give them the capability to land one person on the Moon.
Phases
Launch
Main article: Rocket launch
See also: List of space launch system designs
Rockets are the only means currently capable of reaching orbit or beyond. Other non-rocket spacelaunch technologies have yet to be built, or remain short of orbital speeds. A rocket launch for a spaceflight usually starts from a spaceport (cosmodrome), which may be equipped with launch complexes and launch pads for vertical rocket launches, and runways for takeoff and landing of carrier airplanes and winged spacecraft. Spaceports are situated well away from human habitation for noise and safety reasons. ICBMs have various special launching facilities.
A launch is often restricted to certain launch windows. These windows depend upon the position of celestial bodies and orbits relative to the launch site. The biggest influence is often the rotation of the Earth itself. Once launched, orbits are normally located within relatively constant flat planes at a fixed angle to the axis of the Earth, and the Earth rotates within this orbit.
A launch pad is a fixed structure designed to dispatch airborne vehicles. It generally consists of a launch tower and flame trench. It is surrounded by equipment used to erect, fuel, and maintain launch vehicles. Before launch, the rocket can weigh many hundreds of tonnes. The Space Shuttle Columbia, on STS-1, weighed 2,030 tonnes (4,480,000 lb) at take off.
Reaching space
The most commonly used definition of outer space is everything beyond the Kármán line, which is 100 kilometers (62 mi) above the Earth's surface. The United States sometimes defines outer space as everything beyond 50 miles (80 km) in altitude.
Rockets are the only currently practical means of reaching space. Conventional airplane engines cannot reach space due to the lack of oxygen. Rocket engines expel propellant to provide forward thrust that generates enough delta-v (change in velocity) to reach orbit.
For manned launch systems launch escape systems are frequently fitted to allow astronauts to escape in the case of emergency.
Alternatives
Main article: Non-rocket spacelaunch
Many ways to reach space other than rockets have been proposed. Ideas such as the space elevator, and momentum exchange tethers like rotovators or skyhooks require new materials much stronger than any currently known. Electromagnetic launchers such as launch loops might be feasible with current technology. Other ideas include rocket assisted aircraft/spaceplanes such as Reaction Engines Skylon (currently in early stage development), scramjet powered spaceplanes, and RBCC powered spaceplanes. Gun launch has been proposed for cargo.

Main articles: Escape velocity and Parking orbit
Launched in 1959, Luna 1 was the first known man-made object to achieve escape velocity from the Earth.[4] (replica pictured)
Achieving a closed orbit is not essential to lunar and interplanetary voyages. Early Russian space vehicles successfully achieved very high altitudes without going into orbit. NASA considered launching Apollo missions directly into lunar trajectories but adopted the strategy of first entering a temporary parking orbit and then performing a separate burn several orbits later onto a lunar trajectory. This costs additional propellant because the parking orbit perigee must be high enough to prevent reentry while direct injection can have an arbitrarily low perigee because it will never be reached.
However, the parking orbit approach greatly simplified Apollo mission planning in several important ways. It substantially widened the allowable launch windows, increasing the chance of a successful launch despite minor technical problems during the countdown. The parking orbit was a stable "mission plateau" that gave the crew and controllers several hours to thoroughly check out the spacecraft after the stresses of launch before committing it to a long lunar flight; the crew could quickly return to Earth, if necessary, or an alternate Earth-orbital mission could be conducted. The parking orbit also enabled translunar trajectories that avoided the densest parts of the Van Allen radiation belts.
Apollo missions minimized the performance penalty of the parking orbit by keeping its altitude as low as possible. For example, Apollo 15 used an unusually low parking orbit (even for Apollo) of 92.5 nmi by 91.5 nmi (171 km by 169 km) where there was significant atmospheric drag. But it was partially overcome by continuous venting of hydrogen from the third stage of the Saturn V, and was in any event tolerable for the short stay.
Robotic missions do not require an abort capability or radiation minimization, and because modern launchers routinely meet "instantaneous" launch windows, space probes to the Moon and other planets generally use direct injection to maximize performance. Although some might coast briefly during the launch sequence, they do not complete one or more full parking orbits before the burn that injects them onto an Earth escape trajectory.
Note that the escape velocity from a celestial body decreases with altitude above that body. However, it is more fuel-efficient for a craft to burn its fuel as close to the ground as possible; see Oberth effect and reference.[5] This is another way to explain the performance penalty associated with establishing the safe perigee of a parking orbit.
Plans for future crewed interplanetary spaceflight missions often include final vehicle assembly in Earth orbit, such as NASA's Project Orion and Russia's Kliper/Parom tandem.
Astrodynamics
Main article: Orbital mechanics
Astrodynamics is the study of spacecraft trajectories, particularly as they relate to gravitational and propulsion effects. Astrodynamics allows for a spacecraft to arrive at its destination at the correct time without excessive propellant use. An orbital maneuvering system may be needed to maintain or change orbits.
Non-rocket orbital propulsion methods include solar sails, magnetic sails, plasma-bubble magnetic systems, and using gravitational slingshot effects.

Transfer energy
The term "transfer energy" means the total amount of energy imparted by a rocket stage to its payload. This can be the energy imparted by a first stage of a launch vehicle to an upper stage plus payload, or by an upper stage or spacecraft kick motor to a spacecraft.[6][7]
Reentry
Main article: Atmospheric reentry
Vehicles in orbit have large amounts of kinetic energy. This energy must be discarded if the vehicle is to land safely without vaporizing in the atmosphere. Typically this process requires special methods to protect against aerodynamic heating. The theory behind reentry was developed by Harry Julian Allen. Based on this theory, reentry vehicles present blunt shapes to the atmosphere for reentry. Blunt shapes mean that less than 1% of the kinetic energy ends up as heat that reaches the vehicle, and the remainder heats up the atmosphere.
Landing
The Mercury, Gemini, and Apollo capsules all splashed down in the sea. These capsules were designed to land at relatively low speeds with the help of a parachute. Russian capsules for Soyuz make use of a big parachute and braking rockets to touch down on land. The Space Shuttle glided to a touchdown like a plane.
Recovery
After a successful landing the spacecraft, its occupants and cargo can be recovered. In some cases, recovery has occurred before landing: while a spacecraft is still descending on its parachute, it can be snagged by a specially designed aircraft. This mid-air retrieval technique was used to recover the film canisters from the Corona spy satellites.
Types
Uncrewed
See also: Uncrewed spacecraft and robotic spacecraft

The MESSENGER spacecraft at Mercury (artist's interpretation)
Uncrewed spaceflight (or unmanned) is all spaceflight activity without a necessary human presence in space. This includes all space probes, satellites and robotic spacecraft and missions. Uncrewed spaceflight is the opposite of manned spaceflight, which is usually called human spaceflight. Subcategories of uncrewed spaceflight are "robotic spacecraft" (objects) and "robotic space missions" (activities). A robotic spacecraft is an uncrewed spacecraft with no humans on board, that is usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe.
Uncrewed space missions use remote-controlled spacecraft. The first uncrewed space mission was Sputnik I, launched October 4, 1957 to orbit the Earth. Space missions where other animals but no humans are on-board are considered uncrewed missions.
Benefits
Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. Telerobotics also allows exploration of regions that are vulnerable to contamination by Earth micro-organisms since spacecraft can be sterilized. Humans can not be sterilized in the same way as a spaceship, as they coexist with numerous micro-organisms, and these micro-organisms are also hard to contain within a spaceship or spacesuit.
Telepresence
Telerobotics becomes telepresence when the time delay is short enough to permit control of the spacecraft in close to real time by humans. Even the two seconds light speed delay for the Moon is too far away for telepresence exploration from Earth. The L1 and L2 positions permit 400-millisecond round trip delays, which is just close enough for telepresence operation. Telepresence has also been suggested as a way to repair satellites in Earth orbit from Earth. The Exploration Telerobotics Symposium in 2012 explored this and other topics.[8]
Human
Main article: Human spaceflight
ISS crew member stores samples
The first human spaceflight was Vostok 1 on April 12, 1961, on which cosmonaut Yuri Gagarin of the USSR made one orbit around the Earth. In official Soviet documents, there is no mention of the fact that Gagarin parachuted the final seven miles.[9] Currently, the only spacecraft regularly used for human spaceflight are the Russian Soyuz spacecraft and the Chinese Shenzhou spacecraft. The U.S. Space Shuttle fleet operated from April 1981 until July 2011. SpaceShipOne has conducted two human suborbital spaceflights.
Sub-orbital
Main article: Sub-orbital spaceflight
The International Space Station in Earth orbit after a visit from the crew of STS-119
On a sub-orbital spaceflight the spacecraft reaches space and then returns to the atmosphere after following a (primarily) ballistic trajectory. This is usually because of insufficient specific orbital energy, in which case a suborbital flight will last only a few minutes, but it is also possible for an object with enough energy for an orbit to have a trajectory that intersects the Earth's atmosphere, sometimes after many hours. Pioneer 1 was NASA's first space probe intended to reach the Moon. A partial failure caused it to instead follow a suborbital trajectory to an altitude of 113,854 kilometers (70,746 mi) before reentering the Earth's atmosphere 43 hours after launch.
The most generally recognized boundary of space is the Kármán line 100 km above sea level. (NASA alternatively defines an astronaut as someone who has flown more than 50 miles (80 km) above sea level.) It is not generally recognized by the public that the increase in potential energy required to pass the Kármán line is only about 3% of the orbital energy (potential plus kinetic energy) required by the lowest possible Earth orbit (a circular orbit just above the Kármán line.) In other words, it is far easier to reach space than to stay there. On May 17, 2004, Civilian Space eXploration Team launched the GoFast Rocket on a suborbital flight, the first amateur spaceflight. On June 21, 2004, SpaceShipOne was used for the first privately funded human spaceflight.
Point-to-point
Point-to-point is a category of sub-orbital spaceflight in which a spacecraft provides rapid transport between two terrestrial locations. Consider a conventional airline route between London and Sydney, a flight that normally lasts over twenty hours. With point-to-point suborbital travel the same route could be traversed in less than one hour.[10] While no company offers this type of transportation today, SpaceX has revealed plans to do so as early as the 2020s using its BFR vehicle.[11] Suborbital spaceflight over an intercontinental distance requires a vehicle velocity that is only a little lower than the velocity required to reach low Earth orbit.[12] If rockets are used, the size of the rocket relative to the payload is similar to an Intercontinental Ballistic Missile (ICBM). Any intercontinental spaceflight has to surmount problems of heating during atmosphere re-entry that are nearly as large as those faced by orbital spaceflight.
Orbital
Main article: Orbital spaceflight
Apollo 6 heads into orbit
A minimal orbital spaceflight requires much higher velocities than a minimal sub-orbital flight, and so it is technologically much more challenging to achieve. To achieve orbital spaceflight, the tangential velocity around the Earth is as important as altitude. In order to perform a stable and lasting flight in space, the spacecraft must reach the minimal orbital speed required for a closed orbit.
Interplanetary
Main article: Interplanetary spaceflight
Interplanetary travel is travel between planets within a single planetary system. In practice, the use of the term is confined to travel between the planets of our Solar System.
Interstellar
Main article: Interstellar travel
Five spacecraft are currently leaving the Solar System on escape trajectories, Voyager 1, Voyager 2, Pioneer 10, Pioneer 11, and New Horizons. The one farthest from the Sun is Voyager 1, which is more than 100 AU distant and is moving at 3.6 AU per year.[13] In comparison, Proxima Centauri, the closest star other than the Sun, is 267,000 AU distant. It will take Voyager 1 over 74,000 years to reach this distance. Vehicle designs using other techniques, such as nuclear pulse propulsion are likely to be able to reach the nearest star significantly faster. Another possibility that could allow for human interstellar spaceflight is to make use of time dilation, as this would make it possible for passengers in a fast-moving vehicle to travel further into the future while aging very little, in that their great speed slows down the rate of passage of on-board time. However, attaining such high speeds would still require the use of some new, advanced method of propulsion.
Intergalactic
Main article: Intergalactic travel
Intergalactic travel involves spaceflight between galaxies, and is considered much more technologically demanding than even interstellar travel and, by current engineering terms, is considered science fiction.
Spacecraft
Main article: Spacecraft
An Apollo Lunar Module on the lunar surface
Spacecraft are vehicles capable of controlling their trajectory through space.
The first 'true spacecraft' is sometimes said to be Apollo Lunar Module,[14] since this was the only manned vehicle to have been designed for, and operated only in space; and is notable for its non aerodynamic shape.
Propulsion
Main article: Spacecraft propulsion
Spacecraft today predominantly use rockets for propulsion, but other propulsion techniques such as ion drives are becoming more common, particularly for unmanned vehicles, and this can significantly reduce the vehicle's mass and increase its delta-v.
Launch systems

The first reusable spacecraft, the X-15, was air-launched on a suborbital trajectory on July 19, 1963. The first partially reusable orbital spacecraft, the Space Shuttle, was launched by the USA on the 20th anniversary of Yuri Gagarin's flight, on April 12, 1981. During the Shuttle era, six orbiters were built, all of which have flown in the atmosphere and five of which have flown in space. The Enterprise was used only for approach and landing tests, launching from the back of a Boeing 747 and gliding to deadstick landings at Edwards AFB, California. The first Space Shuttle to fly into space was the Columbia, followed by the Challenger, Discovery, Atlantis, and Endeavour. The Endeavour was built to replace the Challenger, which was lost in January 1986. The Columbia broke up during reentry in February 2003.

The first automatic partially reusable spacecraft was the Buran (Snowstorm), launched by the USSR on November 15, 1988, although it made only one flight. This spaceplane was designed for a crew and strongly resembled the US Space Shuttle, although its drop-off boosters used liquid propellants and its main engines were located at the base of what would be the external tank in the American Shuttle. Lack of funding, complicated by the dissolution of the USSR, prevented any further flights of Buran.
Per the Vision for Space Exploration, the Space Shuttle was retired in 2011 due mainly to its old age and high cost of the program reaching over a billion dollars per flight. The Shuttle's human transport role is to be replaced by the partially reusable Crew Exploration Vehicle (CEV) no later than 2021. The Shuttle's heavy cargo transport role is to be replaced by expendable rockets such as the Evolved Expendable Launch Vehicle (EELV) or a Shuttle Derived Launch Vehicle.
Scaled Composites SpaceShipOne was a reusable suborbital spaceplane that carried pilots Mike Melvill and Brian Binnie on consecutive flights in 2004 to win the Ansari X Prize. The Spaceship Company has built its successor SpaceShipTwo. A fleet of SpaceShipTwos operated by Virgin Galactic planned to begin reusable private spaceflight carrying paying passengers (space tourists) in 2008, but this was delayed due to an accident in the propulsion development.[15]
Challenges
Main article: Effect of spaceflight on the human body
Space disasters
Main article: Space accidents and incidents
All launch vehicles contain a huge amount of energy that is needed for some part of it to reach orbit. There is therefore some risk that this energy can be released prematurely and suddenly, with significant effects. When a Delta II rocket exploded 13 seconds after launch on January 17, 1997, there were reports of store windows 10 miles (16 km) away being broken by the blast.[16]
Space is a fairly predictable environment, but there are still risks of accidental depressurization and the potential failure of equipment, some of which may be very newly developed.
In 2004 the International Association for the Advancement of Space Safety was established in the Netherlands to further international cooperation and scientific advancement in space systems safety.[17]
Weightlessness
Main article: Weightlessness
Astronauts on the ISS in weightless conditions. Michael Foale can be seen exercising in the foreground.
In a microgravity environment such as that provided by a spacecraft in orbit around the Earth, humans experience a sense of "weightlessness." Short-term exposure to microgravity causes space adaptation syndrome, a self-limiting nausea caused by derangement of the vestibular system. Long-term exposure causes multiple health issues. The most significant is bone loss, some of which is permanent, but microgravity also leads to significant deconditioning of muscular and cardiovascular tissues.
Radiation
Once above the atmosphere, radiation due to the Van Allen belts, solar radiation and cosmic radiation issues occur and increase. Further away from the Earth, solar flares can give a fatal radiation dose in minutes, and the health threat from cosmic radiation significantly increases the chances of cancer over a decade exposure or more.[18]
Life support
Main article: Life support system
In human spaceflight, the life support system is a group of devices that allow a human being to survive in outer space. NASA often uses the phrase Environmental Control and Life Support System or the acronym ECLSS when describing these systems for its human spaceflight missions.[19] The life support system may supply: air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences such as radiation and micro-meteorites may also be necessary. Components of the life support system are life-critical, and are designed and constructed using safety engineering techniques.
Space weather
Main article: Space weather
Aurora australis and Discovery, May 1991.
Space weather is the concept of changing environmental conditions in outer space. It is distinct from the concept of weather within a planetary atmosphere, and deals with phenomena involving ambient plasma, magnetic fields, radiation and other matter in space (generally close to Earth but also in interplanetary, and occasionally interstellar medium). "Space weather describes the conditions in space that affect Earth and its technological systems. Our space weather is a consequence of the behavior of the Sun, the nature of Earth's magnetic field, and our location in the Solar System."[20]
Space weather exerts a profound influence in several areas related to space exploration and development. Changing geomagnetic conditions can induce changes in atmospheric density causing the rapid degradation of spacecraft altitude in Low Earth orbit. Geomagnetic storms due to increased solar activity can potentially blind sensors aboard spacecraft, or interfere with on-board electronics. An understanding of space environmental conditions is also important in designing shielding and life support systems for manned spacecraft.
Environmental considerations
Rockets as a class are not inherently grossly polluting. However, some rockets use toxic propellants, and most vehicles use propellants that are not carbon neutral. Many solid rockets have chlorine in the form of perchlorate or other chemicals, and this can cause temporary local holes in the ozone layer. Re-entering spacecraft generate nitrates which also can temporarily impact the ozone layer. Most rockets are made of metals that can have an environmental impact during their construction.
In addition to the atmospheric effects there are effects on the near-Earth space environment. There is the possibility that orbit could become inaccessible for generations due to exponentially increasing space debris caused by spalling of satellites and vehicles (Kessler syndrome). Many launched vehicles today are therefore designed to be re-entered after use.
Before his inauguration on March 4, 1801, President Thomas Jefferson asked Meriwether Lewis, a 29-year-old career officer in the U.S. Army, to join him in the White House as his personal secretary. Jefferson knew Lewis and Lewis's family, as they were neighbors of his Monticello, Virginia, estate. Lewis, a staunch Jeffersonian Democrat, tested the loyalty of top Army officers to the President and reported back to Jefferson. Lewis was sent with sensitive messages to the ministers of foreign powers, and generally assisted the President. But most of all Lewis listened. Lewis absorbed Jefferson's ideas on geography, science, politics, American Indians, and diplomacy. It seems that Lewis was being groomed to lead Jefferson's expedition into the West.
On January 18, 1803, President Jefferson sent a special message to Congress about the proposed expedition. He noted with concern the fact that the British were carrying on a lucrative fur trade with American Indians along the northern border of the United States and into the West. He approached Congress with the idea that "an intelligent officer with 10 or 12 chosen men, fit for the enterprise and willing to undertake it, taken from our posts, where they may be spared without inconvenience, might explore the whole line, even to the Western ocean ..." (Jackson 10-13). In this message, Jefferson portrayed the major goal of the projected expedition as a diplomatic one, in which the explorers "could have conferences with the natives" about commerce, and gain admission for American traders among the various Indian tribes. The other major goal of the expedition, barely stated by Jefferson on January 18, was a scientific one--to not only explore but map and chronicle everything of interest, as he put it, along "the only line of easy communication across the continent." Jefferson took great care to describe the project as a cheap one which would not cost the taxpayers much money. "Their arms & accouterments, some instruments of observation, & light & cheap presents for the Indians would be all the apparatus they could carry, and with an expectation of a soldier's portion of land on their return would constitute the whole expense." Jefferson knew that diplomacy, especially with the goal of increased commerce, could be sold to Congress; scientific discovery and description could not. One seemed practical, the other less so. Thus Jefferson asked for $2,500 to fund the expedition (based on Lewis's initial estimates). (Jackson 8-9 and 13)
On about March 15, 1803, Lewis arrived in Harpers Ferry, Virginia (today's West Virginia), to obtain rifles and other equipment for the expedition, including an iron boat frame. The construction of the boat detained him longer than he had expected, and he stayed in Harpers Ferry for about a month. The boat was made in two sections, each weighing 22 pounds, which could be fitted together to form the skeleton of a boat of 40 feet in length, and would be covered with animal hides and sealed together with pitch. This special boat could be used high in the mountains if they were unable to make dugout canoes.
Besides procuring equipment, Lewis was also expected to take crash courses in several disciplines to round out his training as leader of the expedition. With only the precedent of the voyages of James Cook, Lewis was instructed to compile scientific data on every aspect of the terrain through which he would pass. He was prepared for this by Jefferson during the period he served as the President's personal secretary, and during the Spring of 1803 by astronomer Andrew Ellicott, botanist Dr. Benjamin Smith Barton, surveyor and mathematician Robert Patterson, physician Dr. Benjamin Rush, and anatomist Dr. Caspar Wistar (Rush and Wistar were both members of the American Philosophical Society). Lewis also spent his time in Philadelphia procuring supplies, such items as "portable soup," medicine, special uniforms made of drab cloth, tents, tools, kettles, tobacco, corn mills, wine, gunpowder in lead canisters, medical and surgical supplies, and presents. In addition to all of these activities, Lewis most certainly visited the famous museum of Charles Willson Peale, then located on the second floor of Independence Hall.
Lewis left Philadelphia on June 1 and traveled to Washington, D.C. to meet with President Jefferson and make final arrangements for his journey to the Pacific. These included writing a long letter on June 19 to an old friend, William Clark, asking him to be a co-leader of the expedition and to recruit men in his area. Lewis told Clark the real destination of their mission (the Pacific Coast), but told him to use a cover story that the mission was to go up the Mississippi River to its source for his recruitment. Lewis also hinted at secret news just received by President Jefferson: the French had offered the entire territory of Louisiana to the United States for $15 million. On July 3, 1803, official news arrived in the nation's capital--Robert Livingston and James Monroe had purchased the Louisiana Territory from Napoleon's France.
Lewis left Washington on July 5 for Harpers Ferry, where he picked up the more than 3,500 pounds of supplies and equipment he had amassed to take overland to the Pittsburgh area. The Harpers Ferry-made items probably included 15 rifles, 24 pipe tomahawks, 36 tomahawks for American Indian presents, 24 large knives, 15 powder horns and pouches, 15 pairs of bullet molds, 15 wipers or gun worms, 15 ball screws, 15 gun slings, extra parts of locks and tools for replacing arms, 40 fish giggs such as the Indians use with a single barb point, 1 small grindstone and the collapsible iron frame for a canoe. Lewis left Harpers Ferry for the West on July 8. He hired a man named William Linnard with a Conestoga Wagon to haul the supplies to Pittsburgh. The items were so heavy that Linnard had to obtain another wagon. At Elizabeth, Pennsylvania (south of Pittsburgh on the Monongehela River), Lewis was held up for more than a month waiting for his 55-foot keelboat to be built. During this time, Lewis received word from William Clark that he would join the expedition.
On August 31, the keelboat was completed and Lewis began his journey down the Ohio. It is believed that Lewis also purchased what later became known as the "Red Pirogue" at this time, a single-masted boat rowed with seven oars. Lewis investigated ancient Indian mounds on his way down the river at what is now Creek Mounds State Historic Site near Kent, West Virginia. The next day Lewis first mentioned his Newfoundland dog, Seaman, in the journals. The water in the Ohio was low, causing long portages at various points. Lewis reached Cincinnati, Ohio, on September 28, 1803, where he talked with Dr. William Goforth, a local physician who was excavating the fossil remains of a mastodon at the Big Bone Lick in Kentucky. Lewis traveled to Big Bone Lick himself by October 4, and sent a box of specimens back to President Jefferson, along with an extremely detailed letter describing the finds of Goforth--the lengthiest surviving letter written by Lewis.
On October 14, the keelboat arrived at Clarksville, Indiana, where Lewis finally joined William Clark, his slave York, and the "young men from Kentucky" including Joseph and Reubin Field, recruited by Clark on August 1, and Charles Floyd and George Gibson. John Colter officially enlisted on October 15, George Shannon and John Shields on the 19th, Nathaniel Hale Pryor and William Bratton on the 20th. These so-called "nine young men from Kentucky" formed the backbone of the expedition's crew. Whatever inexperience they may have suffered from in October 1803 was rectified quickly at Camp Wood and along the trail in 1804-06. We don't know if these men met Lewis's initial criteria, but they certainly grew into the role as time went on, and hindsight shows that Clark could not have chosen better.
The expedition got under way once more on October 27, moving down the Ohio to Fort Massac, Illinois, by November 11. Today a replica of the American fort as it looked when Lewis and Clark visited in 1803 stands on the site. Lewis hired interpreter George Drouillard and gained volunteers from the U.S. military at Fort Massac: John Newman and Joseph Whitehouse of Daniel Bissell's 1st Infantry Regiment. These were the first active-duty military personnel added to the Corps of Discovery. The most important addition at Massac was Drouillard, or "Drewyer" as his name is most often spelled in the journals. Born north of present-day Detroit, Michigan, Drouillard was half French and half Shawnee Indian. Drouillard possessed skils that members of the expedition lacked to this point--he was a real frontiersman in the mold of Daniel Boone or Simon Kenton, by far the best hunter and woodsman of the entire expedition.
On November 13 the Corps left Fort Massac, arriving in the vicinity of modern Cairo, Illinois, on the 14th. Here Lewis and Clark worked jointly on their first scientific research and description; to study the geography at the junction of the Mississippi and Ohio rivers. On November 16, they began the diplomatic phase of their journey when they visited the Wilson City area of Mississippi County, Missouri, and met with Delaware and Shawnee Indian chiefs. They ended their surveys at Cairo on November 19, and proceeded up the Mississippi River, now working against the current.
Lewis and Clark stopped to describe and climb Tower Rock on November 25, and arrived at Fort Kaskaskia, Illinois, on the 29th. In 1803, Kaskaskia was the U.S. Army post furthest north and furthest west. Kaskaskia was a town of 467 people when Lewis and Clark visited in 1803. Six soldiers enlisted at Kaskaskia from Russell Bissell's Company, 1st U.S. Infantry Regiment: Sgt. John Ordway and privates Peter M. Weiser, Richard Windsor, Patrick Gass, John Boley, and John Collins. In addition, John Dame, John Robertson, Ebeneezer Tuttle, Issac White, and Alexander Hamilton Willard of Capt. Amos Stoddard's company, U.S. Corps of Artillery, also enlisted for the journey. This was a very important crop of men who added immeasurably to the success of the expedition. Francois Labiche, another half-Indian half-Frenchman, enlisted with the expedition on November 30. Another boat, the "White Pirogue," may have been acquired at Kaskaskia. Clark and the men of the Corps departed Kaskaskia on December 3, and camped just below Ste. Genevieve. Lewis remained at Kaskaskia, probably meeting with locals and taking care of the military and paperwork sides of the expedition. On December 4, Clark and the men moved further up the river, passing Ste. Genevieve on the left side, a very prosperous town of about 1,000 residents--equal in size to St. Louis in 1803. Clark and the men next viewed the remains of Fort De Chartres, abandoned for over 30 years, on the right side. On December 6, Lewis left Kaskaskia and traveled to Cahokia along the Illinois roads. Both Lewis and Clark arrived in Cahokia on December 7.

Edward Norton Lorenz
né le 23 mai 1917 à West Hartford, Connecticut, † le 16 avril 2008 à Cambridge
Lorenz découvre le principe fondateur de la théorie du chaos
Né en 1917 à West-Hartford (Connecticut), Edward Lorenz racontait que, enfant, il s'était « toujours intéressé aux nombres » et qu'il était « fasciné par les changements du temps ». Après des études de mathématiques au Dartmouth College (New Hampshire) et à l'Université d'Harvard (Massachusetts), il obtient, en 1948, un doctorat de météorologie au MIT. Une discipline à laquelle il avait décidé de se consacrer lorsqu'il était, durant la seconde guerre mondiale, météorologiste pour l'armée de l'air américaine. Nommé professeur au département de météorologie du MIT, il en sera responsable de 1977 à 1981, avant de prendre sa retraite en 1987.
Au début des années 1960, c'est en faisant tourner un modèle informatique de prévision du temps qu'il observe que des modifications infimes dans les paramètres initiaux peuvent aboutir, au final, à des résultats radicalement différents. Il en tire la conclusion, dans un article publié en 1963, qu'il est impossible de réaliser une prévision météorologique à long terme - au-delà de deux ou trois semaines - avec un degré de précision acceptable, étant donné d'une part les incertitudes inévitables dans les données fournies aux modèles, d'autre part la multiplicité des paramètres (vent, température, humidité...) à prendre en compte.
Il formalise ce constat l'année suivante en décrivant comment, en jouant sur quelques variables seulement, un comportement chaotique peut apparaître dans un système formellement très simple. La théorie du chaos est née. Elle devra sa notoriété à la fameuse question qu'il pose en 1972, lors d'une réunion de l'American Association for the Advancement of Science : « Le battement d'ailes d'un papillon au Brésil déclenche-t-il une tornade au Texas ? »
La formule fera florès. Mais elle sera souvent été interprétée, à tort, comme l'affirmation d'un principe de causalité, une petite cause pouvant avoir de grands effets. En réalité, elle souligne la sensibilité d'un système dynamique - atmosphérique ou autre - aux conditions initiales. Lorenz ajoute d'ailleurs : « Si le battement d'ailes d'un papillon peut déclencher une tornade, il peut aussi l'empêcher. »
Développements féconds
Pour certains historiens des sciences, Edward Lorenz a redécouvert plutôt que véritablement découvert la théorie du chaos. Dès la fin du XIXe siècle, le mathématicien français Henri Poincaré, qui travaillait sur le mouvement des planètes, avait pressenti que les systèmes déterministes n'avaient pas forcément un comportement prédictible, une erreur, même minime, dans la connaissance de l'état initial étant rapidement amplifiée. L'intuition de Poincaré ne fut pas reconnue à sa juste valeur par ses contemporains.
Lorenz, lui, bénéficia de l'émergence de l'informatique et des ordinateurs, dont la puissance de calcul donnait les moyens d'étudier des systèmes gouvernés par un très grand nombre de variables ou des opérations réitérées à l'infini. Ses travaux mirent toutefois plusieurs années à être assimilés par de multiples disciplines scientifiques, à commencer par les mathématiques, pour lesquelles ils ont eu des développements extrêmement féconds.
Membre de l'Académie des sciences américaine, colauréat du prix Crafoord 1983, Edward Lorenz avait reçu, en 1991, le prix Kyoto pour les sciences de la Terre et de la planète, couronnant « une découverte qui a entraîné l'un des changements les plus radicaux dans la conception humaine de la nature depuis Isaac Newton ».
Décrit par ses proches comme « un parfait gentleman et un modèle d'intelligence, d'intégrité et de modestie », cet amateur de ski de fond continuait, quelques semaines avant sa mort, à pratiquer la randonnée, tout en mettant la dernière main à un ultime article scientifique.

Public School Foundation Theresianische Academy
Founded in 1746
831 students status: 2013
Teachers about 130
The Theresianum called state facility with buildings dating back several centuries in Vienna, 4th district, Favoritenstrasse 15, serves as the seat of the public high school of the Foundation Theresianische Academy, as the building for short Theresianum, and the Diplomatic Academy of Vienna. Both institutions have a tradition spanning centuries. Since 2011, the Foundation also offers a kindergarten and an elementary school.

(National Political Institutes of Education (German: Nationalpolitische Erziehungsanstalten; officially abbreviated NPEA, commonly abbreviated Napola for Nationalpolitische Lehranstalt meaning National Political Institution of Teaching) were secondary boarding schools in Nazi Germany. They were founded as "community education sites" after the National Socialist seizure of power in 1933.), Wikipedia
History
1288 an estate was detectable in this area. 1614 the estate with fields, meadows and vineyards was acquired by the Habsburg monarchy, was first described as a Favoritenhof 1623 and served as the widow's home for the Empresses Anna of Austria-Tyrol, Eleonora Gonzaga and Eleonora Magdalena Gonzaga of Mantua-Nevers. For this, the estate was remodeled in 1642 according to plans of Giovanni Battista Carlone to pleasure palace with pleasure garden called Favorita.
The emperors Leopold I, Joseph I and Charles VI. served the Favorita as a preferred summer residence. During this time, extensions were built, the in the second Turkish siege in 1683 originated ravages repaired and sold some of the fields.
Charles' VI. daughter, Maria Theresa, heiress to the throne in the Austrian dominions, in the Kingdom of Bohemia and the Kingdom of Hungary and since 1745, when her husband became Emperor of the Holy Roman Empire, as Empress was dubbed, preferred as summer residence the Schönbrunn Palace and had it expanded. To this decision may have contributed that the Favorita, concerning location and architecture, with Belvedere Castle could not compete, which the for Habsburg victorious commander Eugene of Savoy, of Charles VI. richly endowed, had built about 800 meters to the east form here using a prominent hillside.
The baroque Favorita (it was by now called New Favorita, the Old Favorita had been in the Augarten) in the suburb of Wieden handed Maria Theresia to the Jesuits - with the condition in it to establish an educational institution, a knight's academy for the benefit of the universal essence, but especially the noble youth. Main task should be the raising of educated and loyal government officials and diplomats. In the 18th and 19th Century followed various extensions and increases in the building.
1783 dissolved the reformer Joseph II in the Austrian hereditary lands all knights academies, as well as the Theresianum. In 1797 Emperor Franz II as sovereign approved the reopening under the management of the Piarists. The facade was rebuilt in the classical style. After the revolution of 1848, Emperor Franz Joseph I. disposed the admission of sons of the middle class as students.
The Oriental Academy, founded by Maria Theresa in 1754, was since the 19th Century in the Theresianum. In 1900 renamed, moved the Consular Academy in 1904 in its newly constructed own building (9, Boltzmanngasse 16, since 1947 Embassy of the United States). It was in 1938 by the Nazi regime canceled. Its role was in 1964 by the Diplomatic Academy of Vienna (see below) resumed.
After the "Anschluss" of Austria by Nazi Germany in 1938, the Nazis dissolved the Theresianische Academy and established on 13 March 1939, exactly one year after the "Anschluss", in the buildings a National Political Education Institute (Napola). 1944/1945, the plant was badly damaged by bombs and grenades. 1945, the buildings in the occupied postwar Austria were by the Soviet occupying power monopolised, in the four-sector city of Vienna the 4th district controlling. It handed the Theresianum over to the USIA, the administration of Soviet Property in Austria.
After the State Treaty of 1955, the Austrian State resp. the Foundation Theresianum got the property on 20 September 1955 refunded, and in September 1957, the school system of the private school with public status could be resumed. The re-establishment of the in the war damaged buildings was carried out by the State from 1956 to 1964. In 1964 in a part of the buildings the by the Ministry of Foreign Affairs established Diplomatic Academy of Vienna started operations, with which the Viennese educational establishement for this topic after 60 years returned into the Theresianum .
Since 1989, in the high school female students are accepted, too.
The gymnasium in the presence
In addition to general education, the focus of the school is placed on language education - the compulsory subjects include other than German, English, French, Latin, Russian and mathematics - and in the education to internationality. Special emphasis is placed on politeness and good appearance. An additional service is available in the areas of sport, art, creativity, information and communication technology and music, and economic projects. The school is run as half-and full boarding.
The school campus is 50,000 square meters and includes a soccer field, and a fun court, two other soccer fields, a swimming pool, a tennis court, a running track, two beach volleyball courts, a basketball court, a large, divisible gymnasium and a smaller, older hall, in both of the are climbing walls as well as other sporting items available.
Currently nearly 800 students attend the Theresianische Academy. Many come from more distant states or from abroad and have the opportunity to live in a boarding school in this case.
The selection of professors is made by the respective school management in cooperation with the Vienna Board of Education. The boarding school, as well as some activities are shared with the Lycée Français de Vienne.

Percival Lowell (1855-1916) was an American businessman, author, mathematician, and astronomer who fueled speculation that there were canals on Mars. In 1894, he chose Flagstaff, Arizona as the home of his new observatory, the now famous Lowell Observatory. For the next fifteen years, he studied Mars extensively, and made intricate drawings of the surface markings as he perceived them. He was particularly interested in the canals of Mars, as drawn by Italian astronomer Giovanni Schiaparelli, who was director of the Milan Observatory. Lowell published his views in three books: “Mars” (1895), “Mars and Its Canals” (1906), and “Mars As the Abode of Life” (1908).
Lowell’s works include a full account of the “canals,” single and double, the “oases,” as he termed the dark spots at their intersections, and the varying visibility of both, depending partly on the Martian seasons. He theorized that an advanced but desperate culture had built the canals to tap Mars’ polar ice caps, the last source of water on an inexorably drying planet.
While this idea excited the public, the astronomical community was skeptical. Many astronomers could not see these markings, and few believed that they were as extensive as Lowell claimed. In 1909 the sixty-inch Mount Wilson Observatory telescope in Southern California allowed closer observation of the structures Lowell had interpreted as canals, and revealed irregular geological features, probably the result of natural erosion. The existence of canal-like features was definitely disproved in the 1960s by NASA’s Mariner missions. Today, the surface markings taken to be canals are regarded as an optical illusion.
Lowell's greatest contribution to planetary studies came during the last decade of his life, which he devoted to the search for Planet X, a hypothetical planet beyond Neptune. In 1930 Clyde Tombaugh, working at the Lowell Observatory, discovered Pluto near the location expected for Planet X. Partly in recognition of Lowell's efforts, a stylized P-L monogram – the first two letters of the new planet's name and also Lowell's initials – was chosen as Pluto's astronomical symbol.
Although Lowell's theories of the Martian canals are now discredited, his building of an observatory at the position where it would best function has been adopted as a principle for all observatories. He also established the program and an environment which made the discovery of Pluto by Clyde Tombaugh possible. Craters on the Moon and on Mars have been named after Percival Lowell. He has been described by other planetary scientists as "the most influential popularizer of planetary science in America before Carl Sagan". Lowell is buried on Mars Hill near his observatory.

Saint Hubertus or Hubert (born circa 656 to 658, probably in Toulouse; died May 30, 727 or 728 in Tervuren near Brussels, Belgium), called the "Apostle of the Ardennes" was the first Bishop of Liège. Hubertus is a Christian saint, the patron saint of hunters, mathematicians, opticians and metalworkers, and used to be invoked to cure rabies. Saint Hubert was widely venerated in the Middle Ages.
