Test your brains with the Physics World blackboard quiz

A blackboard at the Perimeter Institute for Theoretical Physics in Waterlook, Canada

BLACKBOARD 1

By Matin Durrani

Can you tell what branch of physics is being described on the blackboard above? It’s one of six photographs taken by the communications folks at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, where blackboards are an integral feature of the building’s design, appearing everywhere from the lifts to coffee areas.

In this quiz, your task is to study six blackboards and match them up with the physics topics they represent. There’s no prize, other than the satisfaction of having at least some inkling of what those clever theorists at the Perimeter are up to.

So here are the six topics:

• Accretion physics and general relativity

• Cosmology

• Neural networks and condensed matter

• Particle physics 1

• Particle physics 2

• Strings

And here are the six blackboards (you can click on each to see it in more detail).

Fermilab at 50: the June 2017 issue of Physics World is now out

PWJun17cover-200By Matin Durrani

With America’s iconic Fermi National Accelerator Laboratory (Fermilab) celebrating its 50th anniversary this month, check out the June 2017 issue of Physics World magazine, which is now live in the Physics World app for mobile and desktop.

Fermilab mades its name with the Tevatron proton–antiproton collider but neutrinos hold the key to the lab’s future, as Ben Still from Queen Mary University of London makes clear in a feature on the physics of these elusive particles.

You can also enjoy a cracking review of Tommaso Dorigo’s new warts-and-all account of life in the CDF collaboration at Fermilab, while Seyda Ipek from the lab pops up in Philip Ball’s homage to the blackboard – which you can also read on physicsworld.com.

Plus don’t miss this month’s Lateral Thoughts, which reveals how one physicist working in a Scottish call centre ended up chatting to Enrico Fermi’s daughter-in-law about her TV.

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

A spotlight on accelerators in industry – sort of

Normally, you’d expect a particle-accelerator conference to focus on research – either the fundamental research done at accelerator facilities around the world, or the applied research required to get such facilities up and running in the first place. And for the most part, that has been absolutely true of the 8th International Particle Accelerator Conference (IPAC), which is taking place this week on the outskirts of Copenhagen, Denmark.

On Tuesday, however, the conference organizers dedicated a session to the ways that accelerator science engages with industry. In a two-hour series of talks, audience members heard from speakers as varied as Bjerne Clausen, CEO of the Danish chemical technologies firm Haldor Topsoe; Bob Kephart, director of the Fermilab-affiliated Illinois Accelerator Research Center (IARC); and Giovanni Anelli, who leads the Knowledge Transfer group at CERN.

Sculpture inspired by neutrino lab unveiled

By Michael Banks

A sculpture inspired by the geometry of the neutrino detector at the Sudbury Neutrino Observatory (SNO) has been unveiled at Queen’s University in Kingston, Canada.

SNO, which operated from 1999 to 2006, was located 2.1 km underground in Sudbury, Ontario, and designed to detect neutrinos from the Sun through their interactions with a large tank of heavy water.

Visiting the most powerful laser in the world

 

By James Dacey

You might find this surprising, but Romania is one of the main reasons I became a journalist. Back in 2006, having recently graduated with a degree in natural sciences, I spent the summer in the Transylvanian city of Brasov, teaching English to school kids. While there, I was talked into writing a few articles about my experiences for the local tourism magazine, Brasov Visitor. To cut a rambling story short, I had a memorable summer and caught the writing bug. Eventually, I landed a job at Physics World, which enabled me to combine my journalistic leanings with my scientific background.

How will Brexit affect science in the rest of the EU?

Brexit panel: left to right are Rolf Tarrach, Ole Petersen, Mark Ferguson and Gail Cardew.

By Hamish Johnston

Here in the UK it’s easy to forget that our exit from the EU could have significant unintended consequences for scientists in the remaining 27 member nations.

Yesterday, I was at a public forum called “Brexit: the scientific impact”, which was held at the Royal Institution in London. While there was much discussion about domestic challenges, the second session – “Brexit: the scientific impact on the EU-27” – provided a fascinating insight into the challenges facing the UK’s neighbours.

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.

Eye-catching signs from March for Science Bristol

By James Dacey

On Saturday, there were almost 600 sister events across the globe in support of the March for Science gathering in Washington, DC. One such event occurred in Bristol, UK, where Physics World magazine is produced, which featured a march and speeches from science communicators. I popped along to the event with my camera and here are some of the most eye-catching signs from the day.

Following the ups and downs of nuclear energy

PWFocus-Nuclear17-cover-200By Margaret Harris

If you’re finding the pace of geopolitical news a bit too rapid at the moment, spare a thought for physicists and engineers working in the nuclear energy sector.

Towards the end of last month, the venerable energy firm Westinghouse Electric issued a press release in which it proudly announced that its AP1000 reactor – a relatively new “passively safe” design in which the reactor core is kept cool without the need for powered pumps or other “active” equipment – had passed a major UK regulatory review. Ordinarily, this would be cause for celebration. The so-called “Generic Design Assessment” process takes years, and completing it helps pave the way for building AP1000s within the UK. An international partnership called NuGen has long hoped to do just that, on a site near Sellafield in north-west England, so in normal times, you might expect it to be celebrating, too.

The STAR of the show

Tokamak design from Applied Fusion Systems

By Michael Banks

You may remember in 2014 when we reported that entrepreneur Richard Dinan – a former star of the UK reality-TV programme Made in Chelsea – was venturing into fusion energy.

He founded the firm Applied Fusion Systems with the aim of building a prototype fusion reactor. The 30 year old, who doesn’t have a university degree, claims to have taught himself tokamak design and employs a small team of scientists who are working on a design.

Well, the firm has now released its first blueprint for a spherical fusion tokamak and is seeking £200m in investment to build not one, but two of the machines.
