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

Solarquest, Pluto and the importance of New Horizons

A photo of the board game Solarquest, which contains images of all nine planets, several of their moons, and a path between them

The Solarquest board, complete with planets, moons and artificial satellites.

By Margaret Harris

Last night, in honour of the New Horizons mission to Pluto, I pulled out my copy of Solarquest. This classic board game was a childhood favourite of mine, and it’s basically Monopoly in space: instead of buying properties named after streets in Atlantic City, New Jersey (or London, if you’re British), you buy planets, moons and artificial satellites. Then, when your fellow players land on an object you own, you charge them rent.

Such nostalgia is all well and good, I hear you say, but what’s it got to do with New Horizons or Pluto? Well, Solarquest’s inventors clearly took their science seriously. By board game standards, there’s quite a lot of physics in it. For example, you can’t leave a planet unless you roll a number high enough to overcome its gravitational pull, and its Monopoly-like property deed cards include facts about each planet and moon as well as their prices.

ILC Science Club, science fiction versus science fact and siblings in physics


By Hamish Johnston

At the end of next week millions of children in England and Wales will start their summer holidays and many parents will now be scrambling to find activities to keep their little dears occupied. Physics World can recommend a virtual trip to ILC Science Kids Club courtesy of the Tokyo Cable Network and Japan’s Advanced Accelerator Association. ILC stands for International Linear Collider, which is one of several proposed to take over when the Large Hadron Collider is eventually retired. In the first video of the series, a boy called Haru learns why scientists are keen on building accelerators from his Uncle Tomo. The video is in Japanese with English subtitles, so as well as learning about particle physics, your little tykes might even pick up a little Japanese.

Getting into the mind of Maxwell

Malcolm Longair on the beauty of Maxwell's equations
Published 150 years ago, Maxwell's paper on electricity and magnetism remains hugely profound
This text will be replaced

By Matin Durrani

In case you’ve forgotten – and shame on you if you have – 2015 has been designated the International Year of Light and Light-based Technologies (IYL 2015).  There’s been loads going on all over the globe, which you can follow on the excellent IYL 2015 blog, and we at Physics World have been in on the act too don’t forget. Our March 2015 issue was devoted to light and we also produced a digital-only collection of our 10 best features on light, which you can read free here.

Atomic time was born 60 years ago today


By Hamish Johnston

“The death of the astronomical second and the birth of atomic time” is how the British physicist Louis Essen described 3 June 1955, when the world’s first practical atomic clock ticked for the first time.

The place was Teddington on the outskirts of London, which is home to the National Physical Laboratory (NPL). Essen’s clock was based on a beam of caesium atoms and was monitored by microwave technology inspired by his wartime work on radar. The clock was more than a metre long and nicknamed the “Flying Bedstead” by engineers at the BBC, who used it as an input for their radio time signal. The clock made atomic time available worldwide for the first time 60 years ago. Then, in 1967, the second was redefined as an SI unit based on an atomic transition in caesium, thereby ending the ancient practice of defining time though astronomical observations.

Was Bruno Pontecorvo a spy?

Frank Close (centre) speaking at Prospect magazine HQ on 12 March 2015

Reflecting on – Frank Close (centre) discusses the life of the Italian physicist Bruno Pontecorvo, who defected to the Soviet Union in 1950.

By Matin Durrani

Like all good publications, Prospect has a strapline about itself – “the leading magazine of ideas”. Physics World is also about ideas, although sadly our magazine, great though it is, doesn’t have adverts for Cartier watches, Embraer executive jets or the Taj Exotica Resort & Spa in the Maldives as Prospect does. Clearly, some people with ideas have more money to spend than others.

I was kindly invited last week by the deputy editor of Prospect, Jay Elwes, to an event he hosted at the magazine’s headquarters in central London. The event featured the University of Oxford physicist Frank Close, who has just published a new book on the life and times of Bruno Pontecorvo. Close was on hand to discuss the key themes of the book, which is entitled Half Life: the Divided Life of Bruno Pontecorvo. Elwes described the attendees as a “small, high-powered group”, including as it did Pauline Neville Jones, the former chair of the UK’s Joint Intelligence Committee and Jonathan Evans, the former director-general of the British security service MI5.

Rediscovering Marie Curie and the pioneering women of science

By Tushna Commissariat

This Sunday, as the world celebrates International Women’s Day, I’ll be thinking of some amazing women who had a huge impact on the world of physics, helping shape the field as we know it today. Indeed, yesterday I was at the Institute of Physics in London, attending a day-long conference on “The lives and times of pioneering women in physics” hosted by the Institute’s Women in Physics group along with its History of Physics group. While there were a host of interesting speakers at the event, undoubtedly the star of the day was French nuclear physicist Hélène Langevin-Joliot, granddaughter of one of the 20th-century’s most famous female physicists – Marie Curie.

Oscar-nominated physics, putting the jump into popping corn and more


By Tushna Commissariat

There is nothing quite like a bowl of hot, buttery popcorn – and it seems as if even physicists are enthralled by it as they dig into the pops and jumps of this tasty snack. A recent article in the New York Times caught our attention this week, as it talked about how a French research duo used high-speed video cameras and a hot plate to see just why a kernel of corn not only pops, but also leaps up as it puffs. The team found that as the kernel’s hull is breached, we hear the popping sound and this is swiftly followed by the jump that happens when a puffy bit of the inside pushes out and makes the corn jump, a bit like a muscle twitch. Take a look at the lovely slow-motion video above of individual kernels leaping about like perfect puffy ballet dancers.

Paris ushers in the International Year of Light

By Matin Durrani in Paris

It was a grey and dank morning yesterday in the French capital, with even the top of the Eiffel Tower shrouded in clouds – perhaps not the most auspicious weather for the official opening ceremony of the International Year of Light and Light-based Technologies (IYL 2015) here at the headquarters of the UN Educational, Scientific and Cultural Organization (UNESCO).

Inside the conference hall, however, all was brightly lit. The stage was bathed in beams of light in all the colours of the rainbow as the 1500 or so delegates first watched an official IYL 2015 video and then listened as a series of dignitaries voiced their backing for the initiative.

These included a message of support from UN director-general Ban Ki-moon read out by an official and a video recording from Irina Bokova, UNESCO director-general. There were also speakers from Ghana, Mexico, New Zealand, Russia and Saudi Arabia – the five nations that took a key role in getting IYL 2015 approved by the UN in late 2013.
