What better way to celebrate Stephen Hawking’s 75th birthday than a limited edition commemorative book?

To mark the occasion, the Isle of Man Post Office has released Albert Einstein to Stephen Hawking: 100 Years of General Relativity – a 32-page glossy tome that features quotes from the two famous physicists.

Live space station upgrade, more zombie physics, T-shirts for LIGO

NASA is live streaming a video of a spacewalk on its Facebook page, and you just might be able to catch it live from the International Space Station – or watch it again. The video shows astronauts Shane Kimbrough and Peggy Whitson upgrading the space station’s power system – and it looks like hard work to me.

Physics in Beijing – a photo tour

By James Dacey

Late last year, I visited the fast-growing physics powerhouse of Beijing, China. Along the way I took snapshots of the people, events and labs I visited – a selection of which I’ve put together here to share my highlights.

During a break from the serious business of science journalism, I visited Beihei Park, a 1000-year-old former imperial park close to the Forbidden City in central Beijing. While looking up at this ornate pavilion ceiling, I couldn’t help being reminded of the ATLAS detector at CERN.

Happy New Year! The January 2017 issue of Physics World is now out

 pwjan17cover-500By Matin Durrani

Happy New Year from all the team at Physics World!

To get things off to a cracking start, check out the January issue of Physics World magazine, which has a wonderful feature by Patrick Hayden and Robert Myers about how the study of “qubits” – quantum bits of information – could be key to uniting quantum theory and general relativity. The issue is now live in the Physics World app for mobile and desktop, and you can also read the article on physicsworld.com from tomorrow.

Elsewhere in the new issue, you can discover how physicists have waded into the debate over whether magnetic fields can control neurons and enjoy a great feature on why some birds don’t kick out intruder cuckoo eggs.

You can also find out just why so many physicists are worried about Donald Trump’s imminent inauguration as US president.

The 10 quirkiest physics stories of 2016

By Michael Banks

From a physicist playing at this year’s Masters golf tournament to an animal halting CERN’s Large Hadron Collider (LHC), physics has had its fair share of bizarre stories this year. Here is our pick of the 10 best, not in any particular order.

Dinner that’s out of this world

Before setting off to the International Space station (ISS) for six months late last year, UK astronaut Tim Peake revealed that one of the meals he would miss most was the classic British roast dinner. So what better way to celebrate his safe return to Earth in June than to create a portrait of him made from his favourite nosh? Designed by UK “food artist” Prudence Staite for the Hungry Horse pub chain, the culinary concoction took 20 hours to make and contained 5 kg of roast potatoes, 3 kg of cauliflower, 2.5 kg of meat, 0.5 kg of carrots, 0.4 kg of garden peas, a whopping 46 Yorkshire puddings and one litre of gravy. The finished portrait weighed in at 12 kg and says “Welcome Home Tim”. Hungry Horse has even offered Tim and his family free roast dinners for life.

Hungry reindeer could mitigate climate change, talking about quantum computing and our breakthroughs of the year

It’s that time of year when everyone is looking for stories with a Christmassy angle. My colleagues here at IOP Publishing are no exception and they have just put out a press release about some reindeer-related physics. Apparently, hungry reindeer in northern Norway are increasing the albedo of their feeding grounds by eating lots of plants. Albedo is a measure of how much sunlight is reflected back from the surface of the Earth – rather than being absorbed and dissipated as heat – and plays an important role in climate. A worry in the far north is that global warming will lead to greater plant cover – which will reduce albedo and lead to even more warming. Now, it looks like reindeer could help break this cycle. “The effect reindeer grazing can have on albedo and energy balances is potentially large enough to be regionally important,” says Mariska te Beest, from Umeå University in Sweden. “It also points towards herbivore management being a possible tool to combat future warming. Most of the arctic tundra is grazed by either domesticated or wild reindeer, so this is an important finding.”

The Science of Heaven

 

By Richard de Grijs in Beijing

Good things come to those who wait. Indeed, it has been almost six years since we initially thought about making an astronomy documentary set in China – and we finally showed it in public last month. The Science of Heaven premiered on 30 November 2016 at my institution, the Kavli Institute for Astronomy and Astrophysics at Peking University. By all accounts, it was very well received. While we are ironing out some final issues before releasing it publicly in early 2017, you can watch the trailer (above).

Waking up to a gravitational wave


By Hamish Johnston

Yesterday we announced the winner of the Physics World 2016 Breakthrough of the Year, which went to the LIGO Scientific Collaboration for its revolutionary, first ever direct observations of gravitational waves. I caught up with six LIGO scientists in the above video Hangout and asked them what it was like when they first realized that they had detected gravitational waves emanating from two coalescing black holes 1.3 billion light-years away.

Freeman Dyson on the physics dream team, Tycho Brahe’s heavy metal, Tintin bags an astronomical sum

By Hamish Johnston

What would it be like to have known Hans Bethe, Wolfgang Pauli, Robert Oppenheimer and Richard Feynman? One person who can tell is the theoretical physicist Freeman Dyson, who recounts his extraordinary life in an interview in Nautilus entitled “My life with the physics dream team”. Born in the UK, he got a degree in mathematics at the University of Cambridge before embarking on a PhD with Bethe at Cornell. Remarkably, Dyson did not complete his doctorate – something he seems rather pleased with: “I was so lucky. I slipped through the cracks.”
