Regular readers will know that Physics World‘s Hamish Johnston and Louise Mayor will be attending the “Convergence” conference at the Perimeter Institute in Canada from tomorrow onwards. While the conference will undoubtedly prove exciting – just look at this list of speakers – it looks like the institute already has convergence on its mind as this month’s Slice of PI contemplates the “converging streams” of art and science. The video above features Perimeter researcher and artist Alioscia Hamma, who finds solace and symmetry in both his art and physics. Watch the video and read more about his work on the Perimeter blog.

Giving out science careers advice is tricky. On the one hand, you want to be encouraging – not least because if you aren’t, there is a chance that your advisee will go on to win a Nobel prize, and you will then look extremely silly. But on the other hand, you also want to prepare the person, mentally, for the possibility of failure. Otherwise, when they do fall short, they may not know how to recover and try again.
The need for balance between encouraging big dreams and preparing for failure was one of the central insights to come out of Sunday’s panel on “Feminism, sexism and bringing up girls” at the Cheltenham Science Festival. After one of the panel members, psychologist Tanya Byron, noted that in clinical practice she sees many bright, successful girls whose fear of failure is “absolutely destroying them”, her fellow panellist Gabriel Weston put her finger on the heart of the problem. How, Weston asked, do we celebrate young women’s achievements and encourage their dreams without also pushing them to be “perfect little glass statues” who shatter under pressure?

“Restoration of sight to the blind” is a brave claim, one with an almost Biblical ring to it. For Daniel Palanker, though, it is beginning to look as if it is an achievable goal. A medical physicist at the University of Stanford, Palanker has developed a prosthetic vision system that replaces damaged photoreceptors in the retina with an array of tiny photodiodes. When infrared images are projected onto this array, the photodiodes convert the light pulses into electrical signals, which are then picked up by the neurons behind the retina and transmitted to the brain. The result is an artificially induced visual response that, while not as good as normal vision, could nevertheless provide “highly functional restoration of sight” to people with conditions such as retinitis pigmentosa or age-related macular degeneration (AMD).

The International Year of Light is a global celebration, but right now, it’s definitely got its heart in San Francisco. For the past five days, experts in optics, lasers and biomedical imaging have been converging on the “city by the bay” for the annual Photonics West conference, and I’ve joined them in order to learn more about the hot topics in optical science.

It’s pretty easy to see why the Royal Shakespeare Company (RSC) wanted to stage a play about J Robert Oppenheimer. There is definitely a bit of Macbeth in the way this ambitious, aloof theoretical physicist rose to become the scientific leader of the Manhattan Project during the Second World War. Equally, there’s a hint of Caesar or Lear in Oppenheimer’s eventual downfall, which came thanks to a toxic combination of political intrigue and his own arrogance.
The parallels between “Oppie” and Shakespeare’s tragic heroes were highlighted on Saturday, when a group of physicists and artists gathered on stage at the RSC’s Swan Theatre for a panel discussion on “Oppenheimer and the Bomb”. The discussion was part of a programme of events related to the RSC’s production of Oppenheimer, a new play written by Tom Morton-Smith and based on Oppenheimer’s life in the 1930s and 40s. During the discussion, one of the panel members, director Angus Jackson, called Oppenheimer “a play about leadership” as much as science, noting that the leadership conflicts that Oppenheimer experienced were “comparable” to those of the heroes in the RSC’s traditional repertoire.

The story of Nuuk began in the early 18th century when a French naval officer landed on a barren, ice-covered island and noted its coordinates in his logbook. The island, he reported, was volcanic in nature, but little else was known about it; indeed, later visitors to its supposed location found no sign of land. Rediscovered in the 20th century, Nuuk was soon visited by a series of scientific expeditions, one of which noted that the island’s surface area was shrinking. An observation station was set up on a prominent headland, but in 2012, it abruptly ceased transmitting; satellite images later revealed that Nuuk had vanished entirely beneath the ocean surface. Coincidentally, the final signal from Nuuk arrived just as the 34th International Geological Congress was meeting in Australia to discuss the emergence of a new, human-influenced geological age: the Anthropocene.
Nuuk and the various forces that contributed to its demise are the subject of a fascinating exhibition currently on show (until 29 November) at the GV Art gallery in London. Lost in Fathoms is a collaboration between an artist, Anaïs Tondeur, and a physicist, Jean-Marc Chomaz, who specializes in fluid dynamics. To develop her ideas about Nuuk, Tondeur spent a year in residence at Chomaz’s Laboratoire d’Hydrodynamique at the Ecole Polytechnique in France, while other parts of the exhibition grew out of a summer school in Cambridge, UK, that focused on fluid dynamics, sustainability and the environment.

Some people fear public speaking more than illness or death. I’m not one of them, but I’ll admit to some qualms on Monday morning, when I travelled to the University of Westminster to speak about science to a group of journalism students.
As I rode the Metropolitan Line train up to Westminster’s Harrow campus, I wondered what sort of speaker the students were expecting. I was giving the talk as part of a Royal Statistical Society (RSS) programme to train journalists in basic statistical principles and how science works; however, unlike most of the people involved in the programme, I am neither a professional scientist nor a statistician. Moreover, the official RSS curriculum places a strong emphasis on statistics and scientific practices in medical science, which isn’t exactly my strong suit either. So while I knew the programme was aimed at helping non-specialists understand basic concepts like risk, the scientific method and the role uncertainty plays in science – all topics that I’m fairly comfortable with – I couldn’t help feeling like a bit of an imposter.

Materials scientist and first-time popular-science author Mark Miodownik was all smiles last night as his book Stuff Matters scooped one of the UK’s top non-fiction awards, the Royal Society Winton Prize for Science Books. The book, an engaging and often highly personal look at some of the everyday materials that make modern civilization possible, was the unanimous choice of the five-member judging panel, coming top in a strong shortlist that also included a history of general relativity, a memoir about cancer and an analysis of the role played by physicists in Nazi Germany.
Miodownik picked up his award – a rectangular prism that looked like glass but was, he informed us, actually made of acrylic – at the end of a ceremony in which he and four of the other shortlisted authors appeared on stage at the Royal Society’s London headquarters to read passages from their books. Earlier in the evening, there had been an audible buzz in the room as Miodownik read from the introduction of Stuff Matters, in which he describes how, as a teenager, he was slashed with a razor blade during an attempted mugging, and how he became obsessed with materials and their properties afterwards. (He is now a materials engineer at University College London.)

“There is nothing like this in Germany,” states Klaus Kern, a director of the Max Planck Institute (MPI) for Solid State Research in Stuttgart, Germany, as we walk around the institute’s Precision Laboratory, which opened in 2012 at a cost of €25m.
Kern took me on a guided tour of the the centre, which he has been involved with since its conception in 2008, during a break from attending a symposium celebrating the life of Manuel Cardona, a former institute director who passed away earlier this year.
The building is unique, not only in Germany but worldwide, as it offers researchers a space in which to do experiments that are seismically, acoustically and electrically isolated from the environment.

When particle physicist Jon Butterworth and cosmologist Pedro Ferreira took the stage last night at the Bristol Festival of Ideas, they did so as representatives of the two pillars of modern physics. Butterworth, a leading member of the ATLAS collaboration at CERN’s Large Hadron Collider, spoke about the discovery of the Higgs boson and the effort to understand the nature of matter on the quantum level. Ferreira, a theorist at the University of Oxford, focused on Einstein’s general theory of relativity, which describes the behaviour of colossal objects such as galaxies and black holes.
The equations of quantum mechanics and general relativity are famously incompatible, but far from starting a Harry Hill-style confrontation (“FIIIIGHT!”), the advocates of the two theories shared the stage amiably, fielding questions from audience members and talking about their respective new books (Smashing Physics for Butterworth, The Perfect Theory for Ferreira). You can hear Ferreira and Butterworth’s responses to some common (and not-so-common) questions in the clips below.
