Die katholische Kirche St. Nicolai in Kalkar bei Kleve am Niederrhein ist unter anderem bekannt für ihre neun geschnitzten Retabel, ihre Kirchenfenster, ihr Chorgestühl, die historische Seifert-Orgel und ihren Marienleuchter.
Die Nicolaikirche ist eine dreischiffige Halle mit zwei parallelen Chören und einem eingebauten Westturm.
Wahrscheinlich wurde der Bau schon 1230 begonnen.
1409 kam es zu einem Brand, nach dem in verschiedenen Bauabschnitten die heute bestehende dreischiffige Halle errichtet wurde.
Die schweren Kriegsschäden sind behoben worden.
Was St. Nicolai jedoch endgültig einzigartig macht, ist die Verbindung dieser mittelalterlichen Kunstwerke mit den neuzeitlichen Kirchenfenstern. Um das Jahr 2000 gestaltete der Wiesbadener Biologe, Physiker und Glasmaler Karl-Martin Hartmann eine Reihe der vormals zerstörten und bis dahin schmucklos gehaltenen Kirchenfenster neu. Als Motive verwendete er u. a. Feynmandiagramme, Abbildungen von Drei-Jet-Ereignissen, Spektroheliogramme (inkl. einer Darstellung des Kometen Hale-Bopp), eine fotografische Aufnahme des Galaxienhaufens Abell 2218, bei dem der von Albert Einstein vorhergesagte Gravitationslinseneffekt beobachtet werden konnte.
The Catholic Church of St. Nicolai in Kalkar in Kleve on the Lower Rhine is known among other things for its nine carved altarpiece, its stained glass windows, its choir stalls, the historical Seifert organ and its Marie chandelier.
The Nicolai Church is a three-aisled hall with two parallel choirs and a built west tower.
Probably the construction was started already in 1230.
1409 there was a fire, according to the existing today with three naves was built in various stages.
The heavy war damage have been rectified.
What makes St. Nicolai however definitively unique is the combination of these medieval art with modern stained glass windows. Around 2000, designed the Wiesbaden biologist, physicist and glass painter Karl-Martin Hartmann a number of formerly destroyed and until then held unadorned church window again. As motives he used, inter alia, Feynman diagrams, pictures of three-jet events, spectroheliograms (incl. A representation of the comet Hale-Bopp), a photograph of the galaxy cluster Abell 2218, in which the predicted by Albert Einstein gravitational lensing effect was observed.
Salzburg is an Austrian city on the border of Germany, with views of the Eastern Alps. The city is divided by the Salzach River, with medieval and baroque buildings of the pedestrian Altstadt (Old City) on its left bank, facing the 19th-century Neustadt (New City) on its right. The Altstadt birthplace of famed composer Mozart, and also Christian Andreas Doppler Austrian mathematician and physicist!

You can view this photo from several angles. You can view it as a photography fan, as an engineer, as a physicist and of course as a mystic. All combined lead me to the perfect art of a creator whose laws in nature are never violated.
An vardir, saniyeden kucuk... Belki milisaniye, belki mikrosaniye ile olculur. Ama o anin degeri hic bir seyle olculemez. O ani yakaladiniz yakaladiniz; yoksa bir daha geri gelmez. O anin kiymetini bilelim. Eger 0.1 san gec kalsaydim bu fotograf olmayacakti. Hayat da oyle degil mi? Kacirilan firsatler, heba edilen saatler, yillar? Ama Rabbimiz ne kadar rahmet sahibi ki, o donmeyecek anlarin yerine bedel olarak "tevbe"yi kabul eder. Ne mutlu "an"i kacirmayanlara... Ne mutlu ani kacirip tevbe edenlere.

Dal 1988, quando per la prima volta fu indetto dal fisico Larry Shaw, il 14 Marzo è il Pi Greco Day.
Il Pi greco è una costante matematica, indicata con la lettera greca, scelta in quanto iniziale di περιφέρεια, circonferenza in greco. Nella geometria piana viene definito come il rapporto tra la lunghezza della circonferenza e quella del suo diametro,
Il Pi Greco Day si celebra il 14 Marzo di ogni anno perché nel sistema anglosassone la data si scrive 3,14 proprio come il numero associato. E poi oggi, a proposito di menti geniali, è anche il compleanno di Albert Einstein.
L’Unione Matematica Internazionale ha intanto proposto che dall’anno prossimo il 14 Marzo diventi Giornata Internazionale della Matematica.
-----------------------------------------------
Since 1988, when for the first time it was announced by the physicist Larry Shaw, March 14 is the Pi Greco Day.
The Greek Pi is a mathematical constant, indicated by the Greek letter, chosen as the initial of περιφέρεια, circumference in Greek. In plane geometry it is defined as the ratio between the length of the circumference and that of its diameter,
Pi Greco Day is celebrated on March 14 of each year because in the Anglo-Saxon system the date is written 3,14 just like the number associated. And then today, with regard to brilliant minds, it is also the birthday of Albert Einstein.
Meanwhile, the International Mathematical Union has proposed that next year, March 14th will become International Mathematics Day.
Look deep into nature, and then you will understand everything better.

The kaleidoscope is an optical toy, where the user sees many beautiful, colourful patterns. It was invented in 1817 by Scottish physicist Sir David Brewster (December 11, 1781 – February 10, 1868). He also invented the binocular camera, the polyzonal lens and the lighthouse illuminator, as well as coming up with an improved version of the stereoscope applied to photography, which was the first portable, 3D viewing device.
The word "kaleidoscope" is derived from the Ancient Greek kalos, "beautiful, beauty", eidos, "that which is seen: form, shape" and skope, "to look to, to examine."

Isaac Newton, born December 25, 1642, Woolsthorpe, Lincolnshire, England, died March 20, 1727, London. English physicist and mathematician, who was the culminating figure of the Scientific Revolution of the 17th century.
Born in the Woolsthorpe, Newton was the son of a local farmer (500 acres). A weak premature baby, Newton was not expected to survive his first day of life, much less 84 years. Deprived of a father before birth, he soon lost his mother who married a second time and his grandmother brought him up.
Shot at f4. By desaturating the image bit by bit, I found out that my camera produces the colour of this clematis flower by mixing blue and magenta. The flower is almost entirely backlit (daylight), and the resulting colour is vastly different when the flower is exposed frontally to the same kind of light (then, it would be a deep dark blue with the slightest hint of magenta). I am not a physicist, but it seems an educated guess that it is the surface of the petals that reacts differently depending on whether the light comes from the back or the front.
...the sun, moon, planets and stars appear to move slowly across the sky. Over the 30 minutes which elapsed above, the stars and planets traveled around 7.5 degrees. The trails reveal their movement across the night sky, from lower left to upper right.

Love After Life: Nobel-Winning Physicist Richard Feynman’s Extraordinary Letter to His Departed Wife
www.brainpickings.org/2017/10/17/richard-feynman-arline-l...
The visitor centers in the American southwest desert parks offer a little introductory movie, and they all begin with "millions of years ago there was a vast inland sea...", which was home to any number of marine life forms. Then the landmasses collided and with other geologic events, the ocean floor was uplifted and the water receded.
Or so they thought.
One day when out walking in Az, I saw this on the sidewalk.
The head of the whale had just breached the crust of the pavement, the little fish was already merrily flitting over the foamy briny.
I had my iPhone with me and the good fortune to document this ground breaking event which will force science to reexamine what it has long believed about the earth.
The sea is still here under our city streets and sidewalks!!
As the Nobel prize winning physicist Max Planck once indicated, science advances one funeral at a time.
I'm hearing a funeral dirge.
I'll let you know if I win the Nobel Prize.
~ Albert Einstein (German born American Physicist who developed the special and general theories of relativity. Nobel Prize for Physics in 1921. 1879-1955)

Presented here is a color-enhanced infrared photograph featuring the "Temple" dedicated to Alessandro Volta, the Tempio Voltiano, which was inaugurated on July 15, 1928. It was built to mark the first centenary of Alessandro Volta's death (1745-1827). Francesco Somaini (1855-1939), owner of a cotton mill in Como and a Member of Parliament, conceived the idea of building a place devoted to the memory of the great physicist and to preserve his scientific tools and documents. He had painfully witnessed the devastating fire that destroyed the pavilions of the Great Exhibition, which was organized in Como for the first centenary of the invention of the electric battery in the summer of 1799. Somaini provided all the necessary financial resources. The architect Federico Frigerio (1873-1959) was put in charge of the project. He believed that “to honour a man who was among the brightest glories of the Napoleonic Era,” the most appropriate style would be the Neoclassical style.
The building was featured on the 10,000 Lira bill.
“One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development.
The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up.
All of this is evidence that human exploitation of the planet is reaching a critical limit.
But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land.
There isn’t any more available.”

Physicists joke that "black holes have no hair", but they mean gravitational singularities.
I just love symmetry, and I'm attracted to it whereever it crosses my way - maybe because I'm a physicist ;-)
This beautiful ceiling I found in Igreja Santa Engrácia, a church that was converted into the National Pantheon, in which important Portuguese personalities are buried (eg numerous presidents, and the famous footballer Eusebio).
Having successfully kept Rebel Rooster under his protective care, Jasper stood tall and proud. It was a rousing chase around the family room.
I use the term "under protective care" loosely. On Rebel Rooster's first day with Jasper, he lost an eyeball to Jasper's teeth. But luckily, in between being a fighter jet pilot and being a nuclear physicist, I spent some time as an eye surgeon so I was able to reattach Rebel's eyeball and he's fully stereoscopic again.
The alpha and the omega. Physicists have been working to develop the "holy grail" therory that mathematically explains the behavior of the universe from the very small - quantum level particles, to the massively large - galaxies, black holes and dark matter. String theory has moved the thinking beyond just the newtonian (large) and quantum (small) prior successes but there are still large gaps in their understanding and mathematical underpinnings have been elusive. Submittal for the October 19, 2020 Macro Monday’s theme of “String”.
This is an early morning shot at Lake McDonald, Apgar Village in Glacier National Park. For those not afflicted with the photography bug, this is a high dynamic range image (HDR) of the sun cresting the mountains on the other side of the lake. What causes a starburst. I don’t know, ask a physicist. All I know is that smaller apertures produce larger sun stars, and the light source typically has to be partially blocked, in this case by the mountain. Different lenses produce different effects, I believe generated by the blades that control the aperture which differ from one lens to another. HDR is simply recording a scene at various brightness levels to expand the capacity of a camera to see more detail in in the darks and the lights. New cameras have greatly expanded dynamic range but still can’t match our eyes. HDR was all the rage for a while until most of the world got tired of the unreality and overly saturated colors normally produced. Although I’m in that crowd, occasionally I slip back and push things a little too far. How about his one? Too far in your opinion? It looks good to me today but there’s no telling if I’ll still like it in a week. For the geeks among us, Sony a1, 24-105 at 33mm, f/22, ISO 100 and six shots with shutter speeds from 1/10 to 1/160th of a second, one stop apart, combined in Lightroom.
This is an example of a photograph exposed for effect. It highlights the idea that a "correct exposure" is indeed a subjective one. It's the outcome that matters. Philosophically, the way we see the world depends entirely on how we want to see it.
Cosmologists are now seriously considering the idea that the universe is actually a "simulation". Even the renowned physicist Michio Kaku and Elon Musk have taken this position. Essentially (and that's a loaded word philosophically), the material nature of the universe is being called into serious question. Could we in fact be living inside an "imagined world"? And who is doing the imagining? The mind boggles.
SIMULATION THEORY (Documentary) - Is Reality Simulated?
Life Electric (also known as The Life Electric) is a contemporary sculpture, dedicated to the physicist Alessandro Volta (1745–1827). Completed in 2015 it is located in Como, Italy. Life Electric was designed by Daniel Libeskind, and was a gift to Como.
Life Electric takes inspiration from the electric tension existing between the two poles of a battery. It creates an idealistic third pole. The sculpture is designed to suggest connections among three of the five natural elements: light, wind and water. Libeskind's artwork aims to create geometries that connects the sky, lake and mountains, elements that typify the Lake Como landscape.

Tuesday, 29th December...the day before Storm Frank is due to hit the UK. Flood-hit areas in the UK are still reeling from severe flooding and bracing themselves for more rain and gale-force winds from a new weather system officially named as Storm Frank.
A lull in the weather, a beautiful day and a chance to visit the castle, quite a few people doing the same thing. Pretty windy already up at the top today, the next two days will be dreadful with torrential rain and gale force winds forecasted for most of the UK.
Mow Cop Castle is situated above the village of Mow Cop, a village that straddles the Staffordshire/Cheshire border. The castle itself was built as a summerhouse in 1754 for Randle Wilbraham I of Rode Hall.
I'm standing in Staffordshire looking out over the Cheshire Plain and the large radio telescope of Jodrell Bank Observatory is clearly visible today.
Happy Birthday Jodrell Bank!
Sir Alfred Charles Bernard Lovell, OBE, FRS (31 August 1913 – 6 August 2012) was an English physicist and radio astronomer.
Jodrell Bank Observatory celebrates its 70th birthday this month. Seventy years ago Bernard Lovell, a physicist at the University of Manchester, switched on some army surplus radar equipment in a muddy field in Cheshire, part of the University’s Botany Department. With permission to stay for just two weeks, he never left. And now Jodrell Bank Observatory is a world-renowned centre of radio astronomy research.
Since 1957, the Lovell Telescope has led the world in exploring the invisible universe using radiowaves. It also holds the distinction of being both the third largest steerable radio telescope in the world and a Grade 1 listed structure.

Georg Christoph Lichtenberg (1742-1799) was a German physicist. As a scientist, he was the first to hold a professorship explicitly dedicated to experimental physics in Germany. He also was a satirist and Anglophile.
The photographs over the next few days are all Infra Red and taken with my converted compact camera. Since Infra Red applies to a limited band in the electromagnetic spectrum (720nms to 1mm), and invisible to the naked eye, these photographs provide us with a glimpse into a parallel world to the one we can see. Here the IR makes the forest structure look like the living organism that it is. It's very reminiscent of the structure of blood vessels for instance.
Unlike the cyanotype method which goes back 180 years to the dawn of photography, Infra Red photography specifically dates from the publication of American physicist Robert Wood's IR photographs in the February 1910 edition of "The Century Magazine" and in the October 1910 edition of the "Royal Photographic Society Journal". Wood took an otherwise scientific process of spectrography and adapted it to capture landscapes. en.wikipedia.org/wiki/Robert_W._Wood
found in Castlemaine, Central Victoria, Australia
At 120 km driving distance from Melbourne. Castlemaine is the main town, officially a city, of The Shire of Mount Alexander, in central Victoria. Population these days about 9000.
Castlemaine began as the centre of the Mount Alexander gold fields in 1850. It was briefly larger than Melbourne, as that city's population moved to Castlemaine to seek it's fortune. Population these days about 8000.
It was the richest alluvial gold field in world history and that title has not yet been surpassed.
At it's height one of the weekly convoys alone, shipped 3 tons of gold to Melbourne.
However, the rich alluvial diggings were worked out within 15-20 years.
Castlemaine was where the "little fellows" became rich, with nearly all the gold being found within 4m of the surface.
Thus small groups of men could band together and work a stake together in the hope of winning the lottery.

Deutsche Röntgen Museum
In der traditionsreichen Tuchmacherstadt Lennep wurde Wilhelm Conrad Röntgen am 27. März 1845 geboren. Der Spross einer Tuchmacherfamilie verbrachte hier seine ersten Lebensjahre. 1895 entdeckte er an der Universität Würzburg die Strahlen, die heute die ganze Welt als Röntgenstrahlen kennt. Röntgens Arbeit revolutionierte nicht nur die gesamte medizinische Diagnostik und Therapie, sie bereitete auch den Weg für neue naturwissenschaftliche Erkenntnisse und viele hochtechnologische Anwendungen. Der geniale Physiker, Entdecker und Forscher wurde 1901 mit dem ersten Nobelpreis für Physik ausgezeichnet.
Lennep Wilhelm Conrad Röntgen was born on March 27, 1845 in the traditional cloth-making town. The offspring of a cloth-making family spent the first years of his life here. In 1895, at the University of Würzburg, he discovered the rays that are now known throughout the world as X-rays. Roentgen's work not only revolutionized the entire field of medical diagnostics and therapy, it also paved the way for new scientific discoveries and many high-tech applications. The brilliant physicist, discoverer and researcher was awarded the first Nobel Prize in Physics in 1901.
Desde fuera, Santa Sofía no intenta seducir. Es un bloque imponente, reforzado por contrafuertes, que parece más preocupado por resistir que por impresionar. Pero basta con cruzar sus puertas para que el tiempo se diluya y el asombro se imponga. Su grandeza no está en las proporciones externas, sino en el espacio que contiene: un interior que desafía, incluso hoy, la lógica de lo posible.
Inaugurada en el año 537, esta es la tercera versión del templo. Las dos anteriores sucumbieron a las revueltas populares, pero la versión 3.0 no solo resistió, sino que cambió la historia de la arquitectura. Para concebir semejante prodigio hicieron falta un físico y un matemático: Isidoro de Mileto y Antemio de Tralles. No se limitaron a diseñar un edificio; imaginaron lo inconcebible para su época.
Los innumerables terremotos que ha sufrido Estambul han intentado derribarla, pero ahí sigue. Y su cúpula sigue siendo el prodigio más evidente: 31,87 metros de diámetro, suspendida a 56,6 metros de altura, flotando como por arte de magia sobre un anillo de ventanas. Durante casi mil años, Santa Sofía fue el edificio religioso más grande del mundo. Lo más asombroso es que, pese a sus dimensiones, no abruma. Todo en ella —la luz, las proporciones, la acústica— está pensado para elevar, no para aplastar.
Para su construcción se emplearon algunos de los materiales más preciosos del mundo antiguo, y todavía se percibe. Columnas de mármol traídas de Éfeso, pórfido de Egipto, piedra verde de Tesalia, ónice de Frigia... Un catálogo de imperios antiguos al servicio de la nueva Roma. Todo fue elegido para deslumbrar.
Y si algo detiene el paso, son los mosaicos. Dorados, delicados, suspendidos en el tiempo, sobreviven como fragmentos de una gloria que fue bizantina, que fue cristiana, que fue imperial. Algunos permanecen cubiertos; otros asoman tímidamente entre yesos y restauraciones. Todos hablan un idioma que mezcla fe, arte y poder. Es imposible no quedarse en silencio ante el Cristo Pantocrátor o la emperatriz Zoe ofreciendo sus dones celestiales.
Hoy, tras su reconversión en mezquita, ya no se puede visitar libremente la planta baja. Y eso significa que uno de los rincones más curiosos ha quedado fuera del alcance de los visitantes: la famosa “columna que llora”, siempre húmeda, envuelta en leyendas. Se dice que si introduces el dedo en su orificio y este sale mojado, tus deseos serán cumplidos. Otros creen que sus aguas tienen poderes curativos. Según la tradición, la columna llora de pena por el sultán Vedud y fue creada, nada menos, con la saliva del profeta Mahoma.

From the outside, Hagia Sophia doesn’t try to seduce. It’s an imposing mass, reinforced with buttresses, more concerned with endurance than with display. But step through its doors, and time dissolves. Awe takes over. Its greatness doesn’t lie in its outer proportions, but in the space it holds within—a space that, even today, defies the logic of what should be possible.
Inaugurated in 537, this is the third version of the building. The two previous ones fell victim to popular uprisings, but version 3.0 not only survived—it changed the course of architectural history. It took a physicist and a mathematician to conceive such a marvel: Isidore of Miletus and Anthemius of Tralles. They didn’t just design a building; they imagined the unimaginable.
The many earthquakes that have shaken Istanbul tried to bring it down, but Hagia Sophia still stands. And its dome remains its most extraordinary feature: 31.87 meters in diameter, suspended 56.6 meters above the ground, seemingly floating on a ring of windows. For nearly a thousand years, it was the largest religious building in the world. What’s most astonishing is that, despite its scale, it doesn’t overwhelm. Everything—its light, proportions, and acoustics—seems designed to uplift rather than oppress.
The materials used in its construction were among the most precious of the ancient world, and that richness is still felt. Marble columns from Ephesus, porphyry from Egypt, green stone from Thessaly, onyx from Phrygia... a catalogue of ancient empires placed at the service of the new Rome. Every detail was chosen to dazzle.
And if anything stops you in your tracks, it’s the mosaics. Golden, delicate, suspended in time—they survive as fragments of a glory that was Byzantine, Christian, imperial. Some remain covered, others peek out timidly from beneath plaster and restorations. They speak a language of faith, art, and power. It’s impossible not to fall silent before the image of Christ Pantocrator, or Empress Zoe offering her celestial gifts to the Redeemer.
Today, since its reconversion into a mosque, the ground floor is no longer freely accessible. That means one of the building’s most curious features is now out of reach: the famous “weeping column,” always moist, wrapped in legend. It’s said that if you insert your finger into the hole and it comes out wet, your wishes will come true. Others believe its waters have healing powers. According to tradition, the column weeps in sorrow for Sultan Vedud, and was created using the saliva of the Prophet Muhammad.
Another picture from my beach series, this time taken again with the drone. It is fascinating how the wave structure of the surf is different every time. And physicists have recently been trying to make us believe that everything is predetermined. The new edition of determinism seems to be in vogue right now. The photo contradicts this.
Soulis: "Μη Mου τους Kύκλους Tάραττε" = "Do Not Disturb My Circles". These were the last words of Archimedes of Syracuse (Αρχιμήδης in Greek) - one of the greatest mathematical minds of all time.

A very belated Birthday Image for my good friend and co-founder of "PANO-Vision", Paul Ewing.
I've blended my usual big city architectural pano-sabotage imagery with a few subtle nods to Paul and his work here. I've noted, frequently, the deep blue of his Arizona skies and he fantastic light that the State seems to have. And off to the right is a shot of my own lengthy shadow, a motif which occurs a lot in Paul's magnificent work. There's something very Joseph Beuys about that shadow, particularly in Paul's work because of his wearing a hat, which is one of Beuys' signature markers.
Included in the image is a quote form Quantum Physicist, David Bohm, from his book, "Wholeness and the Implicate Order". Paul and I have had many a lengthy discussion of how Pano-Sabotage seems to reflect several quantum concepts which question the singular, dictatorial authority of Classical Mechanical Theory and the resultant dangerous mess that such has wrought on the world.
Two Pano-Sabotage pieces next to each other and 4 SOOC shots layered in, looping lines for unification and a text enhancement.

Des friction lights de John Walker aux lucifers de Samuel Jones
Le pharmacien John Walker est celui qui a inventé, en 1827, la première allumette qui s’allume par friction, comme on la connaît aujourd’hui. S’inspirant des travaux d’un physicien et chimiste irlandais, Robert Boyle, il imagine un mélange qui, par friction sur une surface rugueuse, peut s’enflammer. En bon scientifique qu’il était, et ne voulant pas faire connaître le procédé de sa découverte, il refuse de la breveter, se contentant de commercialiser lui-même son produit, et de vaquer à ses occupations de pharmacien, botaniste et minéralogiste. Ce procédé de fabrication des allumettes finit par être breveté sous le nom de lucifers par un certain Samuel Jones. Les lucifers présentaient néanmoins de nombreux problèmes : flamme instable et violente, odeur désagréable. On dit que malgré tous ces désagréments, le nombre de fumeurs augmenta en raison de cette invention. Ils pouvaient enfin déambuler dans la nature, avec leurs cigarettes, cigares et pipes, en toute indépendance.
From John Walker's Friction Lights to Samuel Jones' Lucifers
In 1827, the pharmacist John Walker invented the first friction-lighting match, as we know it today. Inspired by the work of an Irish physicist and chemist, Robert Boyle, he imagined a mixture that could ignite by friction on a rough surface. As a good scientist, and not wanting to make the process of his discovery known, he refused to patent it, contenting himself with marketing his product himself, and going about his business as a pharmacist, botanist and mineralogist. This process for manufacturing matches ended up being patented under the name of Lucifers by a certain Samuel Jones. However, Lucifers presented many problems: unstable and violent flame, unpleasant odor. It is said that despite all these inconveniences, the number of smokers increased because of this invention. They could finally wander around in nature, with their cigarettes, cigars and pipes, in complete independence.

All their energy, every vibration, every BTU of heat, every wave of every particle that was your loved one remains with you in this world. Know that amid energies of the cosmos, they gave as good as they got.
All the photons that have ever bounced off their face, all the particles whose paths were interrupted by their happiness, by the touch of their hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by the one you love. And as you grieve, know that the photons that bounced from them were gathered in the particle detectors that are your eyes, that those photons created within their constellations of electromagnetically charged neurons whose energy will go on forever.
According to the Law of the Conservation of Energy, not a bit of them is gone; they're just less orderly.

It's funny how such creatures, simplistic in so many ways, can inhabit personalities more complex and deep by comparison to the shallow, murky waters of the WalMart kiddie pools that some human beings are made of. He was my shadow, my sentinel, my buddy, my pal. Little did I know that this Valentine's Day gift from an ex would lead to a lasting companionship who's absence is felt, even to this day.
Some people would scoff and say "Oh, it's just a cat." As heartless as those people are, he was so much more than the sum of himself. He probably would've followed me through the Gates of Hell and back, if I'd let him... and give them a piece of his mind in the process, since he was a chatterbox.
Where people would often fail, he would succeed.
Rest in peace, buddy.
Imagine yourself riding a bubble in the wind. The quiet peaceful serenity of floating gently in the breeze, brushing the pecan orchards or drifting silently above the Rio Grande River. The silence is interrupted briefly, as Pilot Bill Lee burns, adding heat to the bubble that keeps us aloft. Then, back to the silence, as we climb, up above the treetops, where we overlook El Paso’s upper valley. Even birds fly by beneath us, seemingly unaware of our presence. This is the joy that is Hot Air Ballooning.
Hot air balloons are the oldest successful human carrying flight technology, dating back to the Montgolfier brothers’ invention in France in 1783. The first hot air balloons were basically cloth bags, sometimes lined with paper, with a smoky fire built on a grill attached to the bottom. They had a tendency to catch fire and be destroyed upon landing. On September 19, 1783 a sheep, a duck and a rooster become the first passengers in a hot air balloon launched by Joseph and Etienne Montgolfier. For manned flights King Louis XVI had originally decreed that condemned criminals would be the first pilots but a young physicist named Pilâtre de Rozier and the Marquis Francois d’Arlandes successfully petitioned for the honour. They took off at 2 p.m. on November 21, 1783 from Château de la Muette in Paris watched by King Louis XVI. They traveled about five and a half miles for 20 minutes - the first free flight made by man.

The title is a pun. There is a theory that space does not expand continuously or constantly but that it fluctuates. "UBC researchers Qingdi Wang and Bill Unruh tackle the question in a new study that tries to resolve a major incompatibility between quantum mechanics and Einstein’s theory of general relativity.
Wang’s calculations provide a completely new physical picture of the universe, one in which the space we live in is fluctuating wildly. At each point, it oscillates between expansion and contraction. As it swings back and forth, the two almost cancel each other but a very small net effect drives the universe to expand slowly at an accelerating rate. This is a new idea in a field where there hasn’t been a lot of new ideas.
“Space-time is not as static as it appears," This has been labelled Accordion theory.

For this photo I found a picture of space in the New Scientist June 2020 and quartered it and then made a concertina of the paper. 2.5" square.
River Kelvin photographed from Kelvinbridge, Glasgow
The River Kelvin... is a tributary of the River Clyde in northern and northeastern Glasgow, Scotland.... The famous physicist William Thomson, 1st Baron Kelvin was named Baron Kelvin in honour of his achievements, named after the river that flowed past his university. Quoted from Wikipedia
Well this photo is definitely a bitter sweet one for me. As I was editing this photo I got the call my uncle Sid, who got me my first camera as a teenager had just passed away in New Jersey. I got to visit him in December and tell him how much I loved him. He was a gentleman and a physicist. He was Sid Medley, and this photo is for him as he will forever be shining over our family. Thanks for having a look. Kris...
When peacocks are ready to mate, they fan out their iridescent tail feathers (known as trains), before rushing at females, shaking those feathers to catch their attention.
But when researchers discovered low-frequency sounds—which are inaudible to humans—coming from this “train rattle” several years back, no one knew how they worked. All they knew was that peahens perked up and paid attention to recordings of these “infrasounds,” even though they couldn’t see the males.
To find out what was going on, Suzanne Kane, a biological physicist at Haverford College in Pennsylvania, and her colleagues decided to look at the feathered crest on top of the peafowls’ heads. During her previous research, she was struck by the resemblance between the short crest feathers—which form a sort of minifan—and the large peacock tail feathers.
Kane and her colleagues gathered the intact head crests of 15 Indian peafowls (Pavo cristatus) and played recordings of the low-frequency sounds produced by the train rattle displays, along with white noise. Using high-speed cameras, they found that the train rattling infrasounds caused the head crests of both males and females to vibrate at their resonance frequency—the point at which they vibrate the strongest—whereas other sounds resulted in little to no movement.
Peacocks also perform a wing-shaking display that Kane says isn’t particularly visually impressive—at least to humans—as it doesn't involve the beautiful tail feathers. However, when the researchers used a mechanical arm to flap a peacock wing in a similar way near three head crests from female peafowl, they found that it caused measurable movements.
“Every time there was a flap the crest vibrated,” Kane explains. This suggests the air flow generated by wing shaking could vibrate the feathers of nearby females, perhaps attracting their attention, the researchers report today in PLOS ONE.
The team cautions that even with the new results, it still hasn’t looked at how female birds respond to these vibrations. Angela Freeman, a biologist at Cornell University who first discovered the low-frequency sounds, says her experiments showed recordings of these infrasounds cause both males and females to become alert and start walking and running, “presumably to locate the signal.”
What scientists need to do next, she says, is figure out how the vibrations are coordinated with other parts of the mating display—and whether the sounds from the shaking tail feathers really do attract the females.
