The physics of bread, the quest for metallic hydrogen and adventures in LIGO land

PWOct17cover-200By Matin Durrani

If you’re a student wondering whether to go into research or bag a job in industry, don’t miss our latest Graduate Careers special, which you can read in the October issue of Physics World.

Philip Judge from the US National Center for Atmospheric Research and his colleagues Isabel Lipartito and Robert Casini first describe how budding researchers should pick a PhD to work on. It’s vital as that first project can determine the tra­jectory of your future career.

But if your eyes are set on a job outside academia, careers guru Crystal Bailey from the American Physical Society runs through your options and calls on academics to learn more about what’s on offer so they can advise their students better.

If you’d rather just stick your head in the sand about your career options, however, then why not enjoy the cover feature of the October issue, in which former Microsoft chief tech officer and Intellectual Ventures boss  Nathan Myhrvold discusses his massive new five-volume treatise Modernist Bread.

Mixing history and science – as well as the results of more than 1600 of his own experiments – the book is sure to be the last word on this foodstuff that humans have been baking for millennia.

Don’t miss either Jon Cartwright’s feature on the quest for metallic hydrogen.

Remember that if you’re a member of the Institute of Physics, you can read the whole of Physics World magazine every month via our digital apps for iOS, Android and Web browsers.

The September 2017 issue of Physics World magazine is now out

PWSep17cover-200By Matin Durrani

Some of the daily challenges facing women in physics are tackled in the latest issue of Physics World magazine, which is now out.

As well as a round-up from the recent International Conference on Women in Physics, which took place in Birmingham, UK, there’s a fascinating feature about the life of Jocelyn Bell Burnell. She discovered pulsars 50 years ago next month and became the first female president of the Institute of Physics, which publishes Physics World.

As Bell Burnell points out, “Fix the women!” is often seen as the solution to why women progress more slowly in physics than men. In fact, she argues, larger problems – notably institutional bias and poor policies – are to blame.

Don’t miss either our cover feature on the stunning images Cassini has been beaming back over the last few months before it plunges into Saturn on 15 September. We’ve also got a great Lateral Thoughts article by Daniel Whiteson, illustrated by PHD Comics artist Jorge Cham. Plus, find out how groups of cells move, communicate and organize themselves in networks.

Our hazardous planet: when the world is out to get you

PWJul17cover-200By Matin Durrani

For people afflicted by last month’s devastating fire at Grenfell Tower in London or for those caught up in recent terrorist atrocities, it can seem that many problems in this world are entirely of our own making.

Yes the modern world has benefited from our collective wisdom and creativity – especially through science and engineering – but often it feels as if irrational human behaviour lies at the root of many of our troubles.

Nevertheless, we should remember that our planet itself holds many natural hazards too, as the latest special issue of Physics World reminds us.

The May 2017 issue of Physics World is now out

PWMay17cover-200By Matin Durrani

Einstein’s equations of general relativity might fit on a physicist’s coffee mug, but solving them is no mean feat. Now, however, the equations have been solved in a cosmological setting for the first time, as Tom Giblin, James Mertens and Glenn Starkman explain in the May 2017 issue of Physics World magazine, which is now live in the Physics World app for mobile and desktop

Elsewhere in the issue, you can enjoy an interview with John Holdren, who spent eight years as Barack Obama’s presidential science adviser. Find out too about the good and bad of nanoparticles and explore the potential that skyrmions – magnetic quasiparticles – could hold as a new form of memory storage.

Don’t miss either this month’s Lateral Thoughts, in which physicist Roger Todd describes how his invention of a system for automatically watering his house plants almost led to a commercial device.

So you want to know about the dark universe?

Big thinker – Catherine Heymans is an observational cosmologist at the University of Edinburgh and author of the new Physics World Discovery ebook The Dark Universe.

By Matin Durrani

It never ceases to amaze me that we know almost nothing about 95% of the universe. Sure, the consensus is that 25% is dark matter and the rest is something dubbed “dark energy”, but beyond that our knowledge is wafer thin.

The flip side, though, is that there’s plenty for physicists to get stuck into. And if you want to get up to speed with the field and find out more about some of its challenges, do check out a new free-to-read Physics World Discovery ebook by Catherine Heymans from the Royal Observatory, University of Edinburgh, UK.

Available in ePub, Kindle and PDF formats, The Dark Universe explains the dark enigma and examines “the cosmologist’s toolkit of observations and techniques that allow us to confront different theories on the dark universe”. And to get you in the mood for all things dark, I asked Heymans some questions about her life as a research scientist. Here’s what she had to say.

We all love a good disaster movie, but when it comes to real life it’s all too easy to downplay a dangerous but distant threat. Many people choose to live on active volcanoes, the citizens of San Francisco know that “the Big One” could strike at any moment, and yet they believe that the benefits of living in those locations outweigh the risk of a severe event happening in their lifetime.

The same dilemma faces the community of scientists, engineers and policy-makers who are working to understand the impacts of space weather – changes in the Earth’s environment that are largely are driven by physical processes originating from the Sun. Space weather has the potential to disrupt or even damage critical infrastructures on Earth, such as the power grids, aviation routes and communication systems that modern societies depend on, but the last notable event dates back to 2003.

That’s why Mike Hapgood, who heads up the Space Weather Group at RAL Space, part of the UK’s Rutherford Appleton Laboratory, has written a new, free-to-read Physics World Discovery ebook called Space Weather. “I thought it would be a great opportunity to highlight what space weather is really about, and to show how we are linking our scientific knowledge to a better understanding of the impacts on society,” he comments.

From blue fogs to Brexit – the April 2017 issue of Physics World is now out

PWApr17cover-500-ruleBy Matin Durrani

“The secret of the blue fog” might sound like a Tintin book, but it’s all about a strange form of liquid crystal that’s the cover story in the April 2017 issue of Physics World magazine, which is now live in the Physics World app for mobile and desktop.

First observed in the late 1800s, only recently have we finally uncovered the structure of these materials, which turn blue when cooled. As Oliver Henrich and Davide Marenduzzo explain, blue liquid crystals could be used for new kinds of display devices.

Elsewhere in the issue, mathematical physicist Jason Lotay explains his work in seven extra dimensions, while science writer Benjamin Skuse examines the challenge for respected physicists with theories outside the mainstream.

Don’t miss either our latest look at Donald Trump’s scientific shenanigans, including an interview with Rush Holt – the physicist-turned-politician who’s now head of the American Association for the Advancement of Science.
