What was life like on a Russian North Pole Drifting Station? Some scientists and researchers were kind enough to lend us photographs, taken on various stations.
An IVO device for measuring the base height of cloud cover. IVO is the Russian abbreviation for this instrument.
Just prior to the start of World War II, the USSR set up a research camp on drifting ice near the North Pole in 1937. The drift continued for 274 days during which the station travelled more the 2,600 kilometers (1,600 miles), obtaining the first scientific observations from that high latitude. In 1950, USSR set up a second station. Between 1937 to 1991, 88 polar crews drifted on ice flows for a total of 29,726 days. This research program is unequalled in the 20th century by duration, variety of observational material, and importance of scientific discoveries. On average researchers spent nine months at each camp.

This is a photograph from the Rathfarnham 5KM Road Race and Fun Run which took place in Rathfarnham, Co. Dublin, Ireland on Sunday 29th September 2013 at 10:00.
This is one of the most popular runs in South County Dublin and is held in support of St. Luke's Cancer Hospital, Rathgar. This year's race attracted over 1,300 participants and the run is open to runners, joggers and walkers. The course is one of the fastest 5ks in the country with a downhill start and finish. This is an excellently organised race with marhsalling at every junction and Garda enforced road closures for the duration of the race.
This is a photograph which is part of a large set of photographs taken at the 1KM and 4KM mark on the course. The entire set of photographs can be found here on our Flickr profile at the following link: www.flickr.com/photos/peterm7/sets/72157635984917744/

Overall Race Summary
Participants: There was a record number of participants with over 1,300 people taking to the start line.
Weather: This race was held on a beautiful autumn morning. There was little or no breeze and there was mild temperatures of around 15C for the race.
Course: Overall this course is a flat and fast course. There is a net gain of 15M over the whole course with slightly downhill gradients at the start and towards the finish. The course is completely left-handed which makes for favourable conditions. All being equal the course provides an excellent opportunity for every from elite competitors to joggers to set a fast time for themselves.
The race starts at the easterly side of the N81 Tempelogue Road and Springfield Avenue. The start area is shown here on Google StreetView (goo.gl/maps/kg7FY). The race follows Springfield Avenue along the side of Bushy Park. The race overlaps the final kilometer and the finish as it proceeds to the Rathfarnham Road (Shown here Google Streetview goo.gl/maps/gRrI6). The route heads north on Rathfarnham road as there is a very gentle incline until the junction with the Temleogue Road is reached and runners make a sharp left turn onto the N81 (shown here Google StreetView goo.gl/maps/51S2t). The race then heads south along Templeogue Road where the runners can see the course unfold straight infront of them. The race turns left at Springfield Avenue again (start area) and the final Kilometer is as the first to the finish area (Google Streetview goo.gl/maps/1R08S) just before the Rathfarnham Road Junction.
Race Headquarters are situated in Terenure College (Google StreetView goo.gl/maps/e0ou9)

I ran in the race - but my photograph doesn't appear here in your Flickr set! What gives?
As mentioned above we take these photographs as a hobby and as a voluntary contribution to the running community in Ireland. Very often we have actually ran in the same race and then switched to photographer mode after we finished the race. Consequently, we feel that we have no obligations to capture a photograph of every participant in the race. However, we do try our very best to capture as many participants as possible. But this is sometimes not possible for a variety of reasons:
►You were hidden behind another participant as you passed our camera
►Weather or lighting conditions meant that we had some photographs with blurry content which we did not upload to our Flickr set
►There were too many people - some races attract thousands of participants and as amateur photographs we cannot hope to capture photographs of everyone
►We simply missed you - sorry about that - we did our best!
You can email us petermooney78 AT gmail DOT com to enquire if we have a photograph of you which didn't make the final Flickr selection for the race. But we cannot promise that there will be photograph there. As alternatives we advise you to contact the race organisers to enquire if there were (1) other photographs taking photographs at the race event or if (2) there were professional commercial sports photographers taking photographs which might have some photographs of you available for purchase. You might find some links for further information above.
Don't like your photograph here?
That's OK! We understand!
If, for any reason, you are not happy or comfortable with your picture appearing here in this photoset on Flickr then please email us at petermooney78 AT gmail DOT com and we will remove it as soon as possible. We give careful consideration to each photograph before uploading.
I want to tell people about these great photographs!
Great! Thank you! The best link to spread the word around is probably www.flickr.com/peterm7/sets

Benjamin Jonson (c. 11 June 1572 – 6 August 1637) was an English Renaissance dramatist, poet and actor. A contemporary of William Shakespeare, he is best known for his satirical plays, particularly Volpone, The Alchemist, and Bartholomew Fair, which are considered his best, and his lyric poems. A man of vast reading and a seemingly insatiable appetite for controversy, Jonson had an unparalleled breadth of influence on Jacobean and Caroline playwrights and poets.
Although he was born in Westminster, London, Jonson claimed his family was of Scottish Border country descent, and this claim may have been supported by the fact that his coat of arms bears three spindles or rhombi, a device shared by a Borders family, the Johnstones of Annandale. His father died a month before Ben's birth, and his mother remarried two years later, to a master bricklayer. Jonson attended school in St. Martin's Lane, and was later sent to Westminster School, where one of his teachers was William Camden. Jonson remained friendly with Camden, whose broad scholarship evidently influenced his own style, until the latter's death in 1623. On leaving, Jonson was once thought to have gone on to the University of Cambridge; Jonson himself said that he did not go to university, but was put to a trade immediately: a legend recorded by Fuller indicates that he worked on a garden wall in Lincoln's Inn. He soon had enough of the trade, probably bricklaying, and spent some time in the Low Countries as a volunteer with the regiments of Francis Vere. In conversations with the poet William Drummond, subsequently published as the Hawthornden Manuscripts, Jonson reports that while in the Netherlands he killed an opponent in single combat and stripped him of his weapons.[1]
Ben Jonson married, some time before 1594, a woman he described to Drummond as "a shrew, yet honest." His wife has not been definitively identified, but she is sometimes identified as the Ann Lewis who married a Benjamin Jonson at St Magnus-the-Martyr, near London Bridge. The registers of St. Martin's Church state that his eldest daughter Mary died in November, 1593, when she was only six months old. His eldest son Benjamin died of the plague ten years later (Jonson's epitaph to him On My First Sonne was written shortly after), and a second Benjamin died in 1635. For five years somewhere in this period, Jonson lived separately from his wife, enjoying instead the hospitality of Lord Aubigny.
By the summer of 1597, Jonson had a fixed engagement in the Admiral's Men, then performing under Philip Henslowe's management at The Rose. John Aubrey reports, on uncertain authority, that Jonson was not successful as an actor; whatever his skills as an actor, he was evidently more valuable to the company as a writer.
By this time, Jonson had begun to write original plays for the Lord Admiral's Men; in 1598, he was mentioned by Francis Meres in his Palladis Tamia as one of "the best for tragedy." None of his early tragedies survive, however. An undated comedy, The Case is Altered, may be his earliest surviving play.
In 1597, a play co-written with Thomas Nashe entitled The Isle of Dogs was suppressed after causing great offence. Arrest warrants for Jonson and Nashe were subsequently issued by Elizabeth's so-called interrogator, Richard Topcliffe. Jonson was jailed in Marshalsea Prison and famously charged with "Leude and mutynous behavior", while Nashe managed to escape to Great Yarmouth. A year later, Jonson was again briefly imprisoned, this time in Newgate Prison, for killing another man, an actor Gabriel Spenser, in a duel on 22 September 1598 in Hogsden Fields,[1] (today part of Hoxton). Tried on a charge of manslaughter, Jonson pleaded guilty but was subsequently released by benefit of clergy, a legal ploy through which he gained leniency by reciting a brief bible verse in Latin, forfeiting his 'goods and chattels' and being branded on his left thumb.[2]
In 1598, Jonson produced his first great success, Every Man in his Humour, capitalising on the vogue for humour plays that had been begun by George Chapman with An Humorous Day's Mirth. William Shakespeare was among the first cast. This play was followed the next year by Every Man Out of His Humour, a pedantic attempt to imitate Aristophanes. It is not known whether this was a success on stage, but when published, it proved popular and went through several editions.
Jonson's other work for the theater in the last years of Elizabeth I's reign was unsurprisingly marked by fighting and controversy. Cynthia's Revels was produced by the Children of the Chapel Royal at Blackfriars Theatre in 1600. It satirized both John Marston, who Jonson believed had accused him of lustfulness, probably in Histrio-Mastix, and Thomas Dekker, against whom Jonson's animus is not known. Jonson attacked the same two poets again in 1601's Poetaster. Dekker responded with Satiromastix, subtitled "the untrussing of the humorous poet". The final scene of this play, whilst certainly not to be taken at face value as a portrait of Jonson, offers a caricature that is recognisable from Drummond's report - boasting about himself and condemning other poets, criticising performances of his plays, and calling attention to himself in any available way.
This "War of the Theatres" appears to have been concluded with reconciliation on all sides. Jonson collaborated with Dekker on a pageant welcoming James I to England in 1603 although Drummond reports that Jonson called Dekker a rogue. Marston dedicated The Malcontent to Jonson and the two collaborated with Chapman on Eastward Ho, a 1605 play whose anti-Scottish sentiment landed both authors in jail for a brief time.
At the beginning of the reign of James I of England in 1603 Jonson joined other poets and playwrights in welcoming the reign of the new king. Jonson quickly adapted himself to the additional demand for masques and entertainments introduced with the new reign and fostered by both the king and his consort Anne of Denmark.
Jonson flourished as a dramatist during the first decade or so of James's reign; by 1616, he had produced all the plays on which his reputation as a dramatist depends. These include the tragedy of Catiline (acted and printed 1611), which achieved only limited success, and the comedies Volpone, (acted 1605 and printed in 1607), Epicoene, or the Silent Woman (1609), The Alchemist (1610), Bartholomew Fair (1614) and The Devil is an Ass (1616). The Alchemist and Volpone appear to have been successful at once. Of Epicoene, Jonson told Drummond of a satirical verse which reported that the play's subtitle was appropriate, since its audience had refused to applaud the play (i.e., remained silent). Yet Epicoene, along with Bartholomew Fair and (to a lesser extent) The Devil is an Ass have in modern times achieved a certain degree of recognition. While his life during this period was apparently more settled than it had been in the 1590s, his financial security was still not assured. In 1603, Overbury reported that Jonson was living on Aurelian Townsend and "scorning the world."
His trouble with English authorities continued. In 1603, he was questioned by the Privy Council about Sejanus, a politically-themed play about corruption in the Roman Empire. He was again in trouble for topical allusions in a play, now lost, in which he took part. After the discovery of the Gunpowder Plot, he appears to have been asked by the Privy Council to attempt to prevail on a certain priest to cooperate with the government; the priest he found was Father Thomas Wright, who heard Fawkes's confession(Teague, 249).
At the same time, Jonson pursued a more prestigious career as a writer of masques for James' court. The Satyr (1603) and The Masque of Blackness (1605) are but two of the some two dozen masques Jonson wrote for James or for Queen Anne; the latter was praised by Swinburne as the consummate example of this now-extinct genre, which mingled speech, dancing, and spectacle. On many of these projects he collaborated, not always peacefully, with designer Inigo Jones. Perhaps partly as a result of this new career, Jonson gave up writing plays for the public theaters for a decade. Jonson later told Drummond that he had made less than two hundred pounds on all his plays together.
1616 saw a pension of 100 marks (about £60) a year conferred upon him, leading some to identify him as England's first Poet Laureate. This sign of royal favour may have encouraged him to publish the first volume of the folio collected edition of his works that year. Other volumes followed in 1640–41 and 1692. [See: Ben Jonson folios.]
In 1618, Ben Jonson set out for his ancestral Scotland on foot. He spent over a year there, and the best-remembered hospitality which he enjoyed was that of the Scottish poet, Drummond of Hawthornden. Drummond undertook to record as much of Jonson's conversation as he could in his diary, and thus recorded aspects of Jonson's personality that would otherwise have been less clearly seen. Jonson delivers his opinions, in Drummond's terse reporting, in an expansive and even magisterial mood. In the postscript added by Drummond, he is described as "a great lover and praiser of himself, a contemner and scorner of others".
While in Scotland, he was made an honorary citizen of Edinburgh. On returning to England, he was awarded an honorary Master of Arts degree from Oxford University.
The period between 1605 and 1620 may be viewed as Jonson's heyday. In addition to his popularity on the public stage and in the royal hall, he enjoyed the patronage of aristocrats such as Elizabeth Sidney (daughter of Sir Philip Sidney) and Lady Mary Wroth. This connection with the Sidney family provided the impetus for one of Jonson's most famous lyrics, the country house poem To Penshurst.
The 1620s began a lengthy and slow decline for Jonson. He was still well-known; from this time dates the prominence of the Sons of Ben or the "Tribe of Ben", those younger poets such as Robert Herrick, Richard Lovelace, and Sir John Suckling who took their bearing in verse from Jonson. However, a series of setbacks drained his strength and damaged his reputation.
Jonson returned to writing regular plays in the 1620s, but these are not considered among his best. They are of significant interest for the study of the culture of Charles I's England. The Staple of News, for example, offers a remarkable look at the earliest stage of English journalism. The lukewarm reception given that play was, however, nothing compared to the dismal failure of The New Inn; the cold reception given this play prompted Jonson to write a poem condemning his audience (the Ode to Myself), which in turn prompted Thomas Carew, one of the "Tribe of Ben," to respond in a poem that asks Jonson to recognize his own decline.[3]
The principal factor in Jonson's partial eclipse was, however, the death of James and the accession of King Charles I in 1625. Justly or not, Jonson felt neglected by the new court. A decisive quarrel with Jones harmed his career as a writer of court masques, although he continued to entertain the court on an irregular basis. For his part, Charles displayed a certain degree of care for the great poet of his father's day: he increased Jonson's annual pension to £100 and included a tierce of wine.
Despite the strokes that he suffered in the 1620s, Jonson continued to write. At his death in 1637 he seems to have been working on another play, The Sad Shepherd. Though only two acts are extant, this represents a remarkable new direction for Jonson: a move into pastoral drama. During the early 1630s he also conducted a correspondence with James Howell, who warned him about disfavour at court in the wake of his dispute with Jones.
Jonson is buried in Westminster Abbey, with the inscription "O Rare Ben Johnson" (sic) set in the slab over his grave. It has been suggested that this could be read "Orare Ben Jonson" (pray for Ben Jonson), which would indicate a deathbed return to Catholicism, but the carving shows a distinct space between "O" and "rare".[4] Researchers suggest that the tribute came from William D’Avenant, Jonson’s successor as Poet Laureate, as the same phrase appears on his gravestone nearby.[4][clarification needed] The fact that he was buried in an upright grave could be an indication of his reduced circumstances at the time of his death,[5] although it has also been written that Jonson asked for a grave exactly 18 inches square from the monarch and received an upright grave to fit in the requested space.[6] The same source claims that the epitaph came from the remark of a passerby to the grave.

I liked the look of all of the head stabilizers behind the wire chairs.
No, these are not actually torturous. These are here because it's impossible to sit still long enough for the amount of time necessary to get a proper exposure. If you don't use a brace, then the picture will be blurry. I once heard a museum volunteer tell visitors that women were forced to "endure" these. Nope. No enduring, and not just for women.

This device measures the thickness of the cornea by using ultrasound waves. A probe is placed against a numbed cornea and the device returns the thickness in micrometers (µm). A typical cornea has a thickness of about 540 µm. In keratonus patients it can be dramatically lower, I remember one of my eyes measuring 350 µm and being uneligible for corneal crosslinking.

As computational devices evolve, more tools and interfaces are built between the user and the machine. This allows us to complete increasingly complex tasks without having to focus on understanding the nuances of the machine. While this movement is overall positive, one of the drawbacks is that people no longer learn the fundamental processes which allow the tool to work. In addition, by neglecting history, we forget the alternatives to the technologies that we use today – forgotten alternatives that may once have been the status quo. Understanding them would give us a broader view of what we have now, how they superseded their ancestors and what their pitfalls are – important knowledge for those who design possible futures.

CRITICAL ASSEMBLY
THE SECRETS OF LOS ALAMOS 1944:
INSTALLATION BY AMERICAN SCULPTOR JIM SANBORN
------------------------------
In Critical Assembly (1998-2003), Jim Sanborn has re-created the moment in 1945 when human beings first fashioned a practical device powered by nuclear fission. It was called the "gadget" We know it today as the Trinity bomb. When it exploded on July 16 in the New Mexico desert, it permanently changed the human condition.
The place Sanborn takes us to is Los Alamos, in the 1940s a secret town known to the outside world only by its mailing address, Post Office Box 1663, Santa Fe, New Mexico. The scene is a small building in an isolated canyon, far enough from other buildings to contain the radiation. On the tables are "criticality experiments," their purpose to determine how much plutonium 239 can be packed into a bomb for maximum yield without making the bomb unsafe to handle.
Electronic instruments, hardware, furniture, tools and materials used by the Los Alamos Scientific Laboratory during the 1940's and 1950's were acquired by the artist during a six year period from a variety of sources including Lab employees (some of whom had originally made or designed them) These employees had bought these objects many years later as surplus materials at public sales carried out by the Laboratory. Any materials the artist was unable to collect in Los Alamos he machined and fabricated himself.
Plutonium and highly enriched uranium are very unstable metals. If the scientists placed too much of either material in one place it would spontaneously fission or "go critical" causing a tremendous burst of radioactivity that would kill everyone in the immediate area. Conversely if too little material was used to make a bomb it would not detonate at all. This is not to say that sub-critical masses were non-hazardous, in fact they were extremely dangerous. At any given time several of the experimenters tables held a highly radioactive sub-critical mass and a hemispherical reflector (the tables were kept far enough away from each other to reduce the chance of a fission event). The sub-critical masses on the tables were so close to criticality that the reflective properties of the human hand could cause a dramatic rise in radioactivity and the scientists frequently played tunes on the ever present sound of the Geiger counters.
In the late 1940's the scientists at the Lab referred to these experiments as "tickling the tail of the dragon" and the table top work was done with very little personal radioactivity shielding. After 1950 these criticality experiments were done using robotic arms controlled from shielded rooms.
The "Physics Package" as it was called of the "Fat Man" bomb (the one dropped on Nagasaki Japan and tested earlier in Southern New Mexico) is depicted on two metal tables in this installation.
Evocative of both the brilliance of the collective human mind and the potentially devastating power of knowledge, this installation is about the allure of pure science and the ethical dilemmas scientific researchers have faced for decades.
