Hundreds of scientists and science supporters gathered in Copley Square in Boston earlier today in a rally to underline the importance of science. The “Stand up for Science” event was organized to coincide with the annual meeting of the American Association for the Advancement of Science, which is taking place a few blocks away.
To find out more about the aims and purpose of the rally, I hooked up with Geoffrey Supran (picutred below), who helped to organize the event. Having originally studied physics at the University of Cambridgein the UK, Supran obtained a PhD in materials science at the Massachussetts Institute of Technology and is now doing a postdoc in the history of science with Naomi Oreskes at nearby Harvard University.

Rush Holt is that rarity: a physicist who’s also been a politician, having spent 16 years as Democratic Congressman for New Jersey’s 12th congressional district from 1999 to 2015. Those two attributes make him well placed in his current role as president of the American Association for the Advancement of Science (AAAS), which is holding its annual meeting here in Boston.
So when I sat down with Holt yesterday, our conversation naturally focused on the impact on science of Donald Trump’s election as US president. The bouffant-haired, former businessman and reality-TV star may have so far said little about the subject, but Holt believes that “tough and uncertain times” lie ahead for scientific funding. “I think we will be on a very austere budget for all non-defence discretionary activity,” he warns.

How would you like to explore a giant neutrino detector in 3D from the comfort of your mobile phone? VENu is a new smartphone app that allows you explore the physics underlying the MicroBooNE neutrino detector at Fermilab. Developed by Alistair McLean of New Mexico State University and an international team of physicists, the app is used in conjunction with the Google Cardboard headset to provide users with a virtual-reality experience of MicroBooNE. VENu includes games that offer “brain teasing challenges” including working out how to spot a neutrino event in a busy background of cosmic-ray events. The app can be downloaded free of charge from the Apple Store and the Google Android Marketplace.

I bet you can’t resist clicking on “Great wagers in physics history” – which has been compiled by Colin Hunter at the Perimeter Institute for Theoretical Physics in Canada. A surprising number involve Stephen Hawking, whose record on winning is quite abysmal according to Hunter. Hawking’s fellow Cantabrigian Isaac Newton also enjoyed a flutter and accepted Christopher Wren’s offer of 40 shillings to anyone who could – in two months – derive a force law that explained Keplers laws of planetary motion. Newton succeeded, but ran overtime so he didn’t collect the cash. In the image above you can read about another wager involving a “flat-Earth theorist”.

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.”

Like many people, I’m fearful of the imminent Donald Trump presidency, given the many sexist, racist and otherwise unpleasant remarks he made during the US election campaign. However, his slogan – “Make America great again” – proved powerfully effective for many voters. Who, after all, could disagree with renewed domestic glory? Sadly, Trump’s plans for achieving that goal – what little we know of them – are based on such ill-informed and ignorant views that he could damage America’s long-standing leadership in many areas, including science.

The smartphone app Pokémon GO has been all the rage since its recent launch. The augmented-reality game is based on the Nintendo franchise and features players exploring their surroundings while trying to catch as many of the virtual creatures as possible, According to Science, Pokémon have been spotted at a number of science centres including NASA’s Jet Propulsion Laboratory while Symmetry Magazine reports that the game has also infiltrated particle-physics labs such as Fermilab, with scientists seen walking around the lab peering into their phone as they hunt down Pokémon.

It’s my second day here at the 66th Lindau Nobel Laureate Meeting, and it has been a busy one so far.
I have just been chatting with Carlo Rubbia, who shared the 1984 Nobel Prize for Physics for the discovery of the W and Z particles.
Rubbia gave a fantastic talk yesterday about future sources of energy and he was eager to expand on this topic. In particular, he told me about a new technology he has been working on to produce energy from natural gas without releasing any carbon dioxide – a technique called “methane cracking“. While this sounds like a fantastic solution to climate change, at least in the short term, he admits there are lots of technical challenges to overcome.

As we face up to the realities of global warming and see the effects of climate change become apparent, it’s more important than ever that people the world over truly grasp its impact. With this in mind, University of Reading climate scientist Ed Hawkins has created the above animated spiral, which shows how the global temperature has changed over the past 166 years. Using data from the Met Office’s Hadley Centre observations datasets, Hawkins’ animation presents data in a a clear and artistic way. “The pace of change is immediately obvious, especially over the past few decades. The relationship between current global temperatures and the internationally discussed target limits are also clear without much complex interpretation needed,” says Hawkins, who is based at the university’s National Centre for Atmospheric Science. Take a look at his webpage to learn more about the project and for a list of specific weather events that are noticeable in the data.

In case you have ever wondered why so many theoretical physicists study climate change, physicist Tim Palmer from the University of Oxford in the UK has a simple answer: “because climate change is a problem in theoretical physics”. Indeed, Palmer, who won the Institute of Physics’ 2014 Dirac medal, studies the predictability and dynamics of weather and climate, in the hopes of developing accurate predictions of long-term climate change. The answer, according to Palmer, lies at the intersection between chaos theory and inexact computing – which requires us to stop thinking of computers as deterministic calculating machines and to instead “embrace inexactness” in computing. Palmer talked about all this and more in the latest public lecture from the Perimeter Institute in Canada – you can watch his full talk above.
When someone says the word “physicist”, what image or persona comes to mind? That is the question the Institute of Physics (which publishes Physics World) was hoping to answer with its recent member survey based on diversity, titled “What Does a Physicist Look Like?” The Institute’s main aim with this diversity survey, which about 13% of its members responded to, was “to understand the profile of our members and gain some insights into who they are – diverse people with different ages, ethnicities, beliefs and much more”.
