A bright light in Mexico City’s historic centre

Museo de la LuzBy James Dacey in Mexico City

When you visit an unfamiliar city, you can often discover some hidden gems by just wandering the streets with your eyes wide open. This is what happened to Physics World editor Matin Durrani and me yesterday here in Mexico City when we stumbled across the Museo de la Luz (Museum of Light) in the backstreets of the historic city centre.

Located in an old Jesuit college with a beautiful courtyard, the exhibits are spread over three floors covering a wide spectrum of themes, from human vision to the history of the theories of light. What I loved about the place is that it really did offer something for everyone. Too often I find that museums can be great for kids or great for the type of serious adult who loves to leaf through tea-stained archives. El Museo de la Luz manages to hit a sweet spot, being informative and interactive but not too whizz-bang – that is certainly not what I needed yesterday with this jetlag!

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.

All hail the Standard Model, once again

 

By Hamish Johnston

I am a condensed-matter physicist by training and sometimes I struggle to get excited by the latest breakthrough in particle physics – usually because most don’t seem much like breakthroughs to me. The latest hot paper from physicists working on the Large Hadron Collider (LHC) at CERN is a perfect example of what I am talking about.

Writing in Nature this week, physicists working on the CMS and LHCb experiments at CERN announced the discovery of a rare decay of the strange B-meson, as well as further information regarding an even rarer decay of the B0-meson. In both cases the decays produce two oppositely charged muons. An animation of how the strange B-meson decay is detected by the CMS appears in the video above.

Space-station toilet tour, the Louvre’s particle accelerator and more

 

By Tushna Commissariat

I’m sure that many of us, while watching videos of astronauts on board the International Space Station (ISS), floating around with their halo-like hair, have given much thought to how they shower, wash their hair, brush their teeth and, indeed, poop and pee! Well, you can stop stretching your imagination and take a look for yourself – we spotted this story on the Slate website, where you can see the latest videos from the European Space agency, where Italian astronaut Samantha Cristoforetti, who is currently on the ISS, gives us a tour of both the toilet (above) and the “shower” area (below). She even demonstrates exactly how to wash your hair in space – it looks rather fuss-free if you ask me!

A guided tour inside D-Wave’s iconic black box

By Hamish Johnston

Has D-Wave Systems built the world’s first commercial quantum computer? The Canada-based company says it has but some physicists in the quantum-information community beg to differ. Putting aside heady questions like “Does it work?”, I think everyone agrees that the Tardis-sized black boxes that house D-Wave’s processors look great. But what exactly is inside?

Peter Woit is lauded by some for having the courage to speak the truth to the physics establishment, while others see him as an enemy of science. Woit writes the Not Even Wrong blog, which has the same title as a controversial book he once wrote about the merits of string theory. In an article in the latest issue of Nautilus, Bob Henderson profiles Woit and his three decades of doubt over various incarnations of the theory that culminated about 10 years ago in the “string wars”. Henderson’s article is called “The Admiral of the String Theory Wars” and provides a fascinating insight into how the rise of string theory caused Woit to switch from physics to mathematics and his relationships with string theorists – some of whom work in the same building as Woit at Columbia University.

A telescope for the Year of Light

The Galileoscope

The Galileoscope – yours for only $25.

By Michael Banks

Avid readers of physicsworld.com may remember the Galileoscope – a low-cost educational telescope kit that was released for the International Year of Astronomy in 2009.

The telescope marked the 400th anniversary of Galileo’s first telescope, which he presented to policy-makers from the Venetian Republic on 25 August 1609.

Bright lights, big city: a lighting revolution comes to New York

By Robert P Crease in New York

“One well-lit place” is the best way to describe the exhibition hall at Javits Center in New York when it opened on Tuesday morning. I fully expected to be bedazzled at every turn because the venue is hosting LIGHTFAIR, the world’s largest lighting technology trade fair, and so the hall is packed with more than 600 booths designed to highlight, so to speak, the world’s lighting revolution.

Light lunch with a Nobel prize winner

Lunchtime chat: Shuji Nakamura (right) in conversation with Scott Rosenfeld.

 

By Robert P Crease in New York

I seldom go to the Javits Center, New York City’s big, ugly convention space where the food, drinks and parking are way overpriced. Its shows on fashion, furniture and food don’t interest me and it’s a 20-minute walk from the nearest subway station. I once heard comedian Seth Meyer quip that it’s “smack-dab in the middle of New York’s stabbing district”.

On Sunday I went for the first time in years to attend the inaugural lunch of LIGHTFAIR, the world’s largest lighting trade show that draws architects, engineers and designers from all over the world. The featured speaker was Shuji Nakamura, the Japanese-born American materials scientist who shared last year’s Nobel in physics for developing the blue LED. Nakamura described his research path – when he started virtually everyone was working on selenium and he said he chose gallium only because he thought it would make it easier to publish – and was joined on stage by Scott Rosenfeld of the Smithsonian American Art Museum.

Hawking on 1D, Chernobyl fires, psychedelic science and more

 

By Tushna Commissariat

It’s not often that physics, or indeed a physicist, has much in common with pop music or exceedingly popular boy bands. But earlier this week, at an event at the Sydney Opera House titled “An Evening with Stephen Hawking, with Lucy Hawking and Paul Davies”, an audience member asked Hawking (who appeared in holographic form) “What do you think is the cosmological effect of Zayn Malik leaving One Direction?” Watch the video above to see what Hawking said to comfort the distraught fan and how theoretical physics truly may have all the answers.
