So here we are in Baltimore to attend the 2016 March meeting of the American Physical Society (APS). We’re writing this at the window seats in a burrito bar on Pratt Street while staring at the hulk that is the Baltimore Convention Center, where nigh-on 10,000 physicists will be congregating all week.

We’ve been playing a game of “spot the APS attendee” while tucking into our burritos. Without wishing to stereotype physicists (okay, go on then, we will) they’re the ones with the backpacks stuffed with poster tubes, pulling little trolley suitcases, looking lost before veering towards the convention centre.

There are also some physicists inside Chipotle Mexican Grill – you can tell because they’re huddled around laptops looking at PowerPoint presentations showing graphs of Fermi surfaces and topological insultators. Probably not the usual subject of discussion in here.

Scientists battle celebrities, a quantum ‘unconference’ and space travel, past and future

 

By Tushna Commissariat

Its been a strange week for scientists and celebrities popping up together on the world stage – what with rapper B.o.B and Neil deGrasse Tyson’s very public face-off about the former’s conspiracy theory claims of the Earth being flat  – but it didn’t end there. In a celebrity trio that is even more surprising, physicist Stephen Hawking has come together with Hollywood actor Paul Rudd, (most recently starring in the film Ant-Man) in a video narrated by Keanu Reeves. Earlier this week, Caltech’s Institute for Quantum Information and Matter hosted the event One Entangled Evening: a Celebration of Richard Feynman’s Legacy. As a promo of sorts for the event – which had special appearances by Rudd, Reeves, Hawking, Bill Gates and even Yuri Milner, apart from actual quantum physicists such as John Preskill and Dave Wineland – they filmed the above video with Rudd and Hawking battling each other at a game of quantum chess. You will have to watch the video to see who wins.

Sparks of inspiration come from many sources, but for some of the 20th century’s most well known scientists, their four-legged pets played a key role. From Tesla’s cat “Macak” – his interest in electricity was lit as a child when he noticed sparks generated while he stroked Macak –  to Schrödinger’s (real live) dog “Burshie”, these intellectual giants sought the company of pets just as we do and over at the Perimeter Institute’s website, you can learn all about “Great physicists and the pets who inspired them”. My favourite “pet” is of course Tycho Brahe’s infamous elk (you can read about it in the image above). With all of these pets about, its a miracle that a paper wasn’t eaten by a naughty dog or cat!

So much has been said about Einstein and his general theory of relativity (GR) that one would assume there isn’t two entire days worth of talks and lectures that could shed new light on both the man and his work. But that is precisely what happened last weekend at Queen Mary University London’s “Einstein’s Legacy: Celebrating 100 years of General Relativity” conference, where a mix of scientists, writers and journalists talked about everything from the “physiology of GR” to light cones and black holes, to M-theory and even GR’s “sociological spin-offs”.

The opening talk, “Not so sudden genius”, was given by journalist and author of “Einstein: A hundred years of relativity“, Andrew Robinson. The talk was very fascinating and early on Robinson outlined that Einstein stood on the shoulders of many scientists and not just “giants” such as Newton and Mach. But he also acknowledged that the scientist was always a bit of a loner and he preferred it this way. Robinson rightly pointed out that until 1907, Einstein was “working in brilliant obscurity” and later, even once fame found him, rootlessness really suited Einstein’s personality – he described himself as “a vagabond and a wanderer”.

Tiny gifts for world leaders, Hubble’s birthday and more

3D Great Wall of China section

By Hamish Johnston and Tushna Commissariat

Last month, China’s president Xi Jinping’s was on a state visit in the UK and while here, he toured a few academic institutions, including the UK’s new National Graphene Institute (NGI) in Manchester and Imperial College London. As we reported in an earlier blog, Nobel-prize-winning Manchester physicist Kostya Novoselov presented President Xi “with a gift of traditional Chinese-style artwork, which Kostya himself had painted using graphene paint”. This week we found out that the Imperial scientists also presented him with a “tiny gift” in the form of a 50 µm scale version of a section of the Great Wall of China, imaged above, created with a Nanoscribe 3D printer. Prince Andrew, who was also on the visit, was given an image of a panda leaping over a bamboo cane, which was printed on the tip of a needle.

X-ray visions of the past, undead physics, stargazing cruises and more

 

By Tushna Commissariat

Peering into a small 17th century metallic box, without damaging its contents, is no mean feat. But thanks to the use of synchrotron radiation, scientists at the European Synchrotron Radiation Facility (ESRF) in Grenoble were able to “see” inside one, using a technique known as synchrotron X-ray phase contrast micro-tomography. They were also able to create a 3D reconstruction of clay medals concealed within the very fragile and badly oxidized box, which was discovered on the archaeological site of the Saint-Laurent church, and is now at the archaeological museum of Grenoble (MAG). Take a look at the video above to see what the box held. You can also learn more about the researcher’s tomography technique in an article of ours.

Tomorrow is Halloween, so we hope you have your physics-themed pumpkins carved and out on your doorsteps. For some spooky reading this week, take a look at Davide Castelvecchi‘s “Zombie physics: 6 baffling results that just won’t die” story over on the Nature News website. In it, he lists six “undead” results – things that physicists just can’t seem to prove or disprove – including long-running disagreements over certain dark-matter results, hemispheric inconsistencies and spinning protons. Let us know what you think are some of the most undead physics results that should be laid to rest, in the comments below. And while you are at it, make sure to look at today’s creepy edition of Fermilab Today to read about the rise of the zombie accelerator and the “The cult of the Tev.”

Quantifying the success of public engagement

Dancers performing Constant Speed

By Matin Durrani

Here in the Physics World office our attention was caught last week by a story in the Times Higher Education. It reported on a lecture given by Simon Singh at the 2:AM conference in Amsterdam, in which the broadcaster, author and former particle physicist criticized some projects that are designed to boost the public’s interest in science, but which, he feels, are not value for money.

The story mentioned several projects facing Singh’s ire, one of which was the 2005 dance Constant Speed that was created to mark the centenary of Einstein’s annus mirabilis. It was commissioned by the Institute of Physics, which publishes Physics World, so naturally Singh’s comments piqued my interest.

US scientists praise nuclear deal with Iran

By Matin Durrani

Earlier this month my colleague Hamish Johnston published a blog post about the 70th anniversary of the bombing of Hiroshima, in which he reported on a piece by the science historian Alex Wellerstein about whether that first use of a nuclear weapon for non-testing purposes was justified.

It’s a hugely contentious issue – some say that the Hiroshima and Nagasaki bombings brought to an end a conflict that might otherwise have dragged on much longer, while others claim that a detonation well away from built-up areas would have been a better deterrent. Either way, the Hiroshima anniversary served as a pertinent reminder of the long and controversial role that physicists have played in designing and creating nuclear weapons, from the Manhattan Project onswards.

However, there have been plenty of physicists who have opposed the development of nuclear arms, including the Bulletin of the Atomic Scientists, which was founded in 1945 by Manhattan Project scientists who “could not remain aloof to the consequences of their work”. Another anti-nuclear group is the UK-based Scientists for Global Responsibility, whose executive director Stuart Parkinson is a physicist. Last week it published a report calling for the UK government not to replace its submarine-based Trident nuclear deterrent.

Now, a group of 29 leading US scientists and engineers, including six Nobel laureates, has written a two-page letter to US President Barack Obama backing the deal that the US – along with China, France, Germany, Russia and the UK – has struck with Iran to limit its development of nuclear weapons and permit inspections in return for a lifting of economic sanctions.

The August 2015 issue of Physics World is now out

 

By Matin Durrani

Mention the two words “science policy” and most physicists’ eyes will probably glaze over. Most of us dream of discovering a new planet or finding the Higgs boson – not poring over budget spreadsheets, championing science to politicians or commenting on legislation.

But science policy is vital in today’s world, which depends hugely on scientific research and in the cover feature of the August issue of Physics World, which is now out, Len Fisher and John Tesh offer 12 practical tips for scientists who want their ideas incorporated into science policy. You’ll be intrigued by what the two authors have to say.

Elsewhere in the issue, as my colleague Tushna Commissariat explains in the video above, there’s a great feature based on an interview with the French physicist Hélène Langevin-Joliot – the granddaughter of Marie Curie. In the article, Langevin-Joliot explains what’s known as the “Curie complex” and gives her own tips for scientific success. Langevin-Joliot didn’t suffer from the complex herself, but she acknowledges that it is a big problem for others and, these days, spends her time actively promoting careers for women in science

This week, India is mourning the loss of an esteemed leader – the country’s 11th president APJ Abdul Kalam, who died on Monday. Kalam was in office from 2002 to 2007 and enjoyed country-wide popularity, even post his presidency. Described by US president Barack Obama as a “scientist and a statesman” in his eulogy, Kalam was a physicist and an aeronautical engineer before he turned to politics, first acting as a science administrator and adviser for nearly four decades before his office run. Indeed, he was heavily involved in India’s nuclear tests and its military missile programme, earning him the moniker of “Missile Man”. In 2007 he was awarded the Royal Society’s King Charles II Medal, which is “awarded to foreign heads of state or government who have made an outstanding contribution to furthering scientific research in their country”.
