Great minds – some of the delegates at the 50th anniversary meeting of the Brazil Physics Society.

There can’t be many physics experiments to have been visited by members of not one, but two different rock bands. But then there’s something fundamentally captivating about the work of the ALPHA collaboration at the CERN particle-physics lab near Geneva, which is studying the properties of antimatter.
Their technique involves firing a powerful laser pulse at a thin metal foil. This creates a plasma in which electrons are accelerated to high energies before bursting out of the foil. When they emerge, coherent terahertz radiation is given off.
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.
“90% of new products are targeted at the richest 10% of the world’s population” – that’s my take-home message from a fascinating presentation by Surya Raghu at the Fall Meeting of the Chinese Physical Society here in Beijing. An engineer by training, Raghu founded US-based Advanced Fluidics in 2001 after a career in academia.
Raghu was speaking to a group of Chinese students about how to embark on a career as an entrepreneur. Student-age is the best time to acquire the mindset of an entrepreneur, says Raghu and he emphasized the concept of “inclusive knowledge transfer”. This a way of ensuring that products developed at universities benefit even the most disadvantaged in the world.
Quantum star: Jian-Wei Pan before his television appearance.

A few weeks ago China launched the world’s first “quantum satellite” from the Jiuquan Satellite Launch Center, which about 1600 km from Beijing. This morning I met the lead scientist on the mission, Jian-Wei Pan of the University of Science and Technology of China, who is visiting Beijing on his way home to Hefei from Jiuquan.
I asked Pan how the mission (called QUESS) was going, and in particular if his team has managed to get the satellite to send entangled pairs of photons back to Earth. He said we would have to wait for the team to write a paper about the satellite’s initial performance – so let’s just say he was in a very good mood! Stay tuned for more information about this pioneering mission that could lead to quantum communications in space.
The cover story in the September 2016 issue of Physics World magazine – now live in the Physics World app for mobile and desktop – reveals the fascinating new field of “crowd breath research”, which can even shed light on how cinema audiences react during the changing scenes in a movie. You can read the article here on physicsworld.com too.
The September issue also shows how to do crystallography without crystals, explains how first data from the Gaia spacecraft could revolutionize astronomy (see the above video for more on that), and contains one physics teacher’s fascinating story about what she did to change her school’s gender balance.
Don’t miss either reader feedback on the potential impact of Britain leaving the EU on physics or Robert P Crease’s Critical Point column on why science denial is one of the most important issues in the US presidential campaign.
Cao has found a great way to combine his passion for mountains and neutrinos: the Cosmic Ray Tau Neutrino Telescope (CRTNT), which, if built, will use an entire mountain in western China as a cosmic neutrino detector.
It’s a lovely warm evening here in Beijing. I have just arrived for an action-packed visit in which I will have a chance to meet some of China’s top physicists and science policy makers.
Over the next few days I’m looking forward to meeting people at the Chinese Physical Society (CPS), the China Association for Science and Technology (CAST), the Ministry of Science and Technology of China (MOST), the National Natural Science Foundation of China (NSFC) and more.
