Physics reveals the mysteries behind art

Artists' secrets: Charles Falco describes how artists used lenses (Courtesy: Tushna Commissariat)

By Sarah Tesh in New Orleans, Louisiana, US

As a physicist who likes to sketch and paint, I love it when art and physics come together. I was therefore excited to see that the APS March Meeting had a variety of talks on the subject. Charles Falco from the University of Arizona in the US told us about his work with the famous artist David Hockney. On a trip to see the 15th century painting The Arnolfini Marriage by Jan van Eyck, Hockney decided that the chandelier was too detailed to have been done freehand. So Falco and Hockney began looking at the intricate parts of paintings by artists through the ages and found that they essentially cheated.

Through focal length and depth-of-field calculations, Falco showed that artists had used optical lenses to project the complicated parts onto the canvas before painting them. They suggest that this has been happening since the 1400s and is a technique used by artists such as Hans Holbein (who painted the iconic portraits of Henry VIII) and Johannes Vermeer (whose work includes Girl with a Pearl Earring). Obviously, they still possessed huge amounts of skill, but it definitely makes me feel a bit better about my own skill level.

Using pottery to communicate science

You might not think theoretical physics and pottery have much in common. But they do now, thanks to a new exhibition being staged at the Knight Webb Gallery in Brixton, south-east London, which opens today.

Entitled Quantum Ceramics, the exhibition is the first solo display of ceramic works by theoretical physicist Nadav Drukker. Based at King’s College London, Drukker makes traditional studio pottery as a new way to communicate his scientific research.

Drukker, who is a string theorist, has six different projects – entitled “Circle”, “Cusp”, “Index”, “Polygons”, “Cut” and “Defect” – with each inspired by one of his research papers. His works are all traditional glazed stoneware and porcelain vessels, but decorated with mathematical symbols.

A laser-bubble mermaid, ode to seven exoplanets, metallic hydrogen is lost

A popular way of melding science and art is to create an image of a mythical being in your lab. Yoshio Hayasaki and colleagues at Utsunomiya University in Japan have made a pretty good likeness of a mermaid using a laser that forms tiny bubbles inside a liquid. “In our display, the microbubble voxels are three-dimensionally generated in a liquid using focused femtosecond laser pulses,” explains team member Kota Kumagai.

She’s the greatest dancer, how to name an element, soccer ball finally orbits Earth

 

By Hamish Johnston

The award for most bizarre title for a scientific paper goes to psychologist Nick Neave and colleagues at the UK’s Northumbria University and University of Lincoln for “Optimal asymmetry and other motion parameters that characterise high-quality female dance”. The team says it used “a data-driven approach to pinpoint the movements that discriminate female dance quality”. Why, you might ask? “The form and significance of attractive dance, however, has been less well studied, and this limits our understanding of its role in human courtship and partner selection.” The above video is from a previous study by the team about what constitutes a good male dancer.

Marie Curie battles downloading robots, happy 50th birthday ILL, a dodgy portrayal of astronomers

By Sarah Tesh

Avid readers of the Physical Review series of journals will be used to clicking on a photograph of Albert Einstein before downloading papers. This is a security feature designed to stop robots from the mass downloading of papers. Now, the American Physical Society – which publishes the journals – has added a photograph of Marie Curie to the anti-robot system. The addition of a famous female physicist was the idea of Anna Watts, who is an astrophysicist at the University of Amsterdam. She has since Tweeted “This makes me incredibly happy.”

Freeman Dyson on the physics dream team, Tycho Brahe’s heavy metal, Tintin bags an astronomical sum

What would it be like to have known Hans Bethe, Wolfgang Pauli, Robert Oppenheimer and Richard Feynman? One person who can tell is the theoretical physicist Freeman Dyson, who recounts his extraordinary life in an interview in Nautilus entitled “My life with the physics dream team”. Born in the UK, he got a degree in mathematics at the University of Cambridge before embarking on a PhD with Bethe at Cornell. Remarkably, Dyson did not complete his doctorate – something he seems rather pleased with: “I was so lucky. I slipped through the cracks.”

The beauty of gravitational waves

Painting by Penelope Cowley depicting gravitational waves is being unveiled at Cardiff University's school of physics and astronomy on 25 November 2016

Science meets art – this painting by Penelope Cowley will be unveiled at Cardiff University’s school of physics and astronomy on 25 November.

By Matin Durrani

A new painting by Welsh artist Penelope Cowley is the latest attempt to bring art and science together. Set to be unveiled on Friday 25 November at Cardiff University’s school of physics and astronomy, the 1.2 × 1.5 m picture was inspired by the recent detection of gravitational waves by the LIGO collaboration.

According to the university, the oil painting “combines a visualization of data taken from the equipment used to detect the first gravitational waves…with an imagination of some of the celestial bodies that are responsible for creating these waves, such as binary black holes and neutron stars”.

The physics of Luke Cage’s skin, meet the ‘mathekniticians’, lessons from the only girl in a physics class

By Hamish Johnston

Marvel’s Luke Cage is a superhero television series that has just debuted on Netflix. Cage’s superpower is that his skin is impervious to bullets and other projectiles fired at him by villains. But could it be possible to create a skin-like layer that would allow someone to emerge unscathed from machine gun fire? The Nerdist’s Kyle Hill has the answer in the above video.

Its officially that time of the year again when we can marvel at this year’s winners of the Insight Astronomy Photographer of the Year 2016. The awards ceremony, held at the Royal Greenwich Observatory, has unveiled some truly spectacular and ethereal shots of our universe. The overall winner this year is a truly amazing composite image of the 2016 total solar eclipse that shows the ‘Baily’s Beads’ phenomenon and was taken by photographer Yu Jun in Luwuk, Indonesia. In the video above, the judges explain why this particular image was the main winner for the year.

Primal colours across the spectrum, impossible space engines

 

By Tushna Commissariat 

Physicists and artists have long been intrigued and drawn in by the various mysteries that light and its many colours offer. In the latest installation to be unveiled at the Natural History Museum in London, artist Liz West has unveiled her stunning new work dubbed Our Spectral Vision. The exhibit aims to delve into the long and complex history of the development of colour and vision “through the eyes of nature”. Our regular readers will recall the many physics papers that look into the same, from the structural colour of butterflies to the nanostructures in avian eggshells to the mantis shrimp’s visual superpowers. West’s exhibit deals with many of these topics and more including some fantastic “350 rarely seen specimens, from beautiful birds to fossils of the first organisms with eyes”. If you are based in the UK, do visit the exhibit and otherwise, take a look at the video above to see through West’s eyes.
