The October 2015 issue of Physics World is out now

 

By  Matin Durrani

It’s amazing the lengths physicists will go to get things done – from building telescopes on the tops of mountains to lowering neutrino detectors to the bottom of the sea and from firing satellites into space to colliding particles in tunnels. We’ve covered all those efforts in
Physics World many times, but there’s one extreme activity that’s been off our radar – until now.

That is the new but little-known field of “speleophysics” – or “the physics of caves” – which we tackle in the cover feature of the October 2015 issue of Physics World magazine. For the small band of researchers who brave the journey underground, being a speleophysicist is almost the perfect job. Armed with helmets, ropes, torches and boots, they’re able to combine their love of physics with a fascination for the nether world – and experience the thrill (and danger) of caving, too.

The September 2015 issue of Physics World is now out

By Matin Durrani

How and where do new ideas in physics emerge? We often think they arise serendipitously, which is why we love stories like Newton discovering gravity after seeing an apple fall. The reality, though, is often very different.

Writing in the September 2015 issue of Physics World magazine, which is now out, theoretical physicist Vitor Cardoso from the University of Lisbon explains his efforts to find out how breakthroughs – both big and small – really emerge. As he discovered through his project The Birth of an Idea, it turns out that how new thoughts arise is often much more of a communal activity than we might think.

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

The July 2015 issue of Physics World is now out

By Matin Durrani

Sometimes, nature does something unexpected – something so rare, transient or remote that only a lucky few of us get to see it in our lifetimes. In the July issue of Physics World, we reveal the physics behind our pick of the weirdest natural phenomena on our planet, from dramatic rogue waves up to 30 m tall, to volcanic lightning that can be heard “whistling” from the other side of the world, and even giant stones that move while no-one is watching. We also tackle tidal bores on rivers and the odd “green flash” that is sometimes seen at sunset.

Plus, we’ve got six fabulous full-page images of a range of weird phenomena, including salt-flat mirrors, firenadoes, “ice towers”, beautifully coloured nacreous clouds, mysterious ice bubbles of gas trapped in columns, as well as my favourite – the delicately wonderful “frost flowers” seen very occasionally on plants.

The June 2015 issue of Physics World is now out

By Matin Durrani

For nearly three decades, physicists have been unable to answer a seemingly simple question: where does proton spin come from? Adding up the spins of the three quarks that make up the proton seems, in principle, straightforward, but physicists have been struggling with a strange problem: the sum of the spins of its three quarks is much less than the spin of the proton itself.

Cover of Physics World June 2015

Known as the “spin crisis”, the topic appears as the cover story of the June 2015 issue of Physics World, which is out now in print and digital formats. In the feature article, science writer Edwin Cartlidge examines the origins of the problem – and whether new experiments could mean we are about to solve it at last.

If you’re a member of the Institute of Physics (IOP), you can get immediate access to the feature with the digital edition of the magazine on your desktop via MyIOP.org or on any iOS or Android smartphone or tablet via the Physics World app, available from the App Store and Google Play. If you’re not yet in the IOP, you can join as an IOPimember for just £15, €20 or $25 a year to get full digital access to Physics World.

The issue also includes a great Lateral Thoughts article by Felix Flicker that’ll have you twisting and bending your arms as you try to follow what he’s on about.

Inside Mexico’s giant centre of learning

 

By Matin Durrani in Mexico City

It’s one of the biggest universities in the world with several hundred thousand students, but the Universidad Nacional Autonóma de México (UNAM) is certainly not the oldest. In fact, the first person to get a degree and PhD in physics at UNAM – Fernando Alba – is still alive. Aged 95, he studied at UNAM’s Institute of Physics shortly after it opened its doors in 1939.

Physics World visit to Mexico kicks off

By Matin Durrani in Mexico City

I don’t know about you, but my trick whenever flying halfway across the world is to shoehorn myself as fast as possible into the new time zone I’m in. Having travelled from the UK to Mexico City with my colleague James Dacey yesterday, that tactic seems to have worked…so far. After staying up till midnight following a mini-feast of fabulous spicy tacos at a nearby restaurant while a thunderstorm broke, I woke up on cue at 7 a.m. as dawn broke in one of the biggest urban areas in the world.

We’re both here to gather material for a Physics World special report on physics in Mexico, which is due out in September. Following fast on the heels of recent reports on India, Brazil, Korea, India (again), Japan and China, the report will shine a light on some of the exciting physics research going on in the country and highlight some of the challenges and opportunities the country’s physicists face, too.

The May 2015 issue of Physics World is now out

By Matin Durrani

A couple of years back, I had the pleasure of travelling 1100 metres below ground to visit a dark-matter laboratory at the bottom of the Boulby Mine on the north-east coast of England. The journey was certainly memorable – it involved plunging down in a rattling lift cage for several minutes with a group of miners setting off on their morning shift. Once in the lab – housed inside a souped-up set of trailers – I interviewed physicist Sean Paling about the experimental projects going on there.

Setting up an underground lab, like that at Boulby, certainly doesn’t come cheap and in recent years, many have started to diversify into new areas. In the May issue of Physics World, which is now out in print and digital formats, Paling and his colleague Stephen Sadler – who is director at DURRIDGE UK Radon Instrumentation – describe the renaissance in the science taking place far beneath our feet. Studies in underground labs now range from Mars rovers to muon tomography and from radioactive dating to astrobiology.

Five amazing physics demonstrations

By Matin Durrani

Even if you’re a hardcore theoretical physicist, I’m sure you’ll agree that experiments are the lifeblood of physics. After all, theory and experiment go hand in hand – and there’s nothing to beat getting your hands dirty to get a proper understanding of the subject.

But how can pupils and students get excited about experiments? Making practical work a key part of exam syllabuses is surely important – yet the danger then is experimental work becomes a chore not a charm.

If you need inspiration, check out the April issue of Physics World magazine, which is now out in print and digital formats. It contains a great feature by Neil Downie – head of sensors at Air Products, Basingstoke, Hampshire, UK and a Royal Academy of Engineering visiting professor at the University of Surrey.

Your secret superpower

By Matin Durrani

The March 2015 issue of Physics World magazine, a special issue about light in our lives that is now out in print, online and via our apps, contains a fascinating feature about an astonishing – and largely unknown – superpower that you perhaps don’t realize you have. It might sound bizarre, but using your naked eyes – and with no additional gadgets whatsoever – you can detect whether or not light is “polarized”. And in the video above, Louise Mayor, features editor of Physics World, tells you how.
