Fancy a bit of particle-physics electronica?
Then make sure you download the latest album from Isle of Wight electronic duo Cosmic Mind Warp.
In a “unique crossover” between the worlds of cosmology, quantum physics and electronic music, Alister Staniland and David Holmberg have just released a new concept album dubbed Subatomic Particles.
The 15-track album, which features songs such as “Large Hadron Collider”, “Quantum Tunnelling” and “Down Quark”, is described by the duo as a “hallucinogenic head-trip through the microscopic world of subatomic particles and the strangeness of quantum physics”.

Regular readers of Physics World will know that I am currently visiting the CERN particle physics lab in Geneva, ahead of the restart of the Large Hadron Collider (LHC) in the coming weeks. My first stop yesterday afternoon was a press conference in which CERN’s director-general Rolf Heuer and other leading physicists briefed us about “Run 2” and what researchers are hoping to discover. You can read about what they had to say here: “Large Hadron Collider fires up in a bid to overturn the Standard Model“.
I managed to squeeze in a quick last-minute visit to the Compact Muon Solenoid (CMS) detector before it is sealed up tight for the next three years. My host was CMS communications officer Achintya Rao, who took me and a few others deep underground into the bowels of the CMS – and what a sight it was!

Loyal sports fans often need a reason for losing beyond “their team was better than ours”, and the latest blame-game in American football comes with a twist of physics to it. The run-up to this year’s Superbowl is no exception. Some disgruntled Indianapolis Colts fans claim that the New England Patriots had taken advantage of deflated footballs to make their decisive 45-7 victory on 18 January, which sends them to the championship game.

Who discovered the Higgs boson? Was it Peter Higgs and a combination of other great minds? The experimentalists at CERN who analysed reams of data? The magnificent machinery of the Large Hadron Collider (LHC) itself? By the time that the next great breakthrough in particle physics comes along, the debate about who makes the discovery could become even more complex. That’s because a new citizen-science project is encouraging anyone with an Internet connection to search for new curiosities in the Higgs data.
“Higgs Hunters” launched this week and invites the public to sift through collision images from the LHC’s ATLAS detector. The task at hand is to look for the paths of charged particles that seem to appear out of thin air in what are known as off-centre vertices. As explained on the Higgs Hunters website, “some scientists think the Higgs could break apart into exotic particles entirely new to science”. On the Higgs Hunters website, citizen scientists help to count the number of particle tracks and can notify the science team if they spot anything out of the ordinary.

CERN has been celebrating its 60th anniversary all this month, but it was in fact six decades ago today – on Wednesday 29 September 1954 – that the lab’s convention was ratified by its first 12 member states: Belgium, Denmark, France, Germany, Greece, Italy, the Netherlands, Norway, Sweden, Switzerland, the UK and Yugoslavia.
Physics World has played its own small part in marking the anniversary, including a careers feature on what skills you need as CERN director-general, a day-in-the-life blog written by current CERN boss Rolf-Dieter Heuer, and an appearance at the lab’s TEDx event last week by our columnist Robert P Crease.
This blog entry rounds off our coverage of CERN at 60 with a few links to classic material from our archives.

“TED”, which stands for Technology, Entertainment, Design, is a non-profit organization that promotes talks on what it calls “ideas worth spreading”; the “x” denotes an independent event organized in that spirit. This is the second TEDxCERN – the first took place last year – and it’s hosted by Brian Cox. More than 1000 people will watch 14 speakers, three performances and three animations; tens of thousands more viewers are expected online.
James Gillies, CERN’s head of communication, invited me to be a speaker. The subject this year, he said, was how science could better engage with major social challenges. He said that my May Physics World column “Why don’t they listen?” – on why scientists have difficulty getting politicians’ ears – had “hit the nail on the head”, and asked if I’d be interested in discussing the idea.
A week at CERN? A great excuse to implore colleagues take over my classes? Sure! All I had to do, I thought, was talk my way through some extended version of the column.
A scientific pyramid scheme, symmetry through the ages, why physics students are “standing a little taller” and more
By Hamish Johnston
Just this week six people were convicted in Bristol of crimes related to running a pyramid scheme. This involves taking money from lots of new investors and giving it to a smaller number of investors who signed up earlier – until the pyramid collapses. Is the current model for training scientists a pyramid scheme of sorts? That is the claim in a piece on the US’s National Public Radio (NPR) website written by Richard Harris.

There is no such thing as a typical day in the life of a CERN director-general (DG), certainly not this one in any case. In my experience, each incumbent has carved out a slightly different role for themself, shaped by the laboratory’s priorities and activities at the time of their mandate. For me, every day goes beyond science, management and administration, and I am particularly fortunate to have been DG through a remarkable period that has seen not only the successful launch of the Large Hadron Collider (LHC) and confirmation of the Brout–Englert–Higgs mechanism, but also an opening of CERN to the world – an area that I have pursued with particular vigour.
As I regularly joke, we have changed the “E” of CERN from “Europe” to “Everywhere”, and that has meant a lot of travel for the CERN DG, as we hold discussions with prospective new members of the CERN family. And when the CERN Council opened up membership to countries from beyond the European region in 2010, it seemed to me that we should also be extending our contacts in other directions as well.

We’re always up for trying new formats and approaches to journalism here at Physics World. You’ve probably seen our documentary-type films, podcasts and 100 Second Science video series, but the latest addition to our repertoire is a short monthly video in which one of our editorial team highlights something in the upcoming or current issue as a kind of taster.
So this month, I decided to take the plunge and get in front of the camera myself to present the third edition of what we have started jokingly referring to in the office as our “fireside chats”. (Here are the July and August versions.)

This week, South Korea’s one and only astronaut, 36-year-old Yi So-yeon, has quit her job, thereby signalling the end of the country’s manned space programme for the time being. In 2008 Yi became the first Korean to go into space, when for 11 days she travelled on board a Russian Soyuz spacecraft to the International Space Station, after being chosen through the government-run Korean Astronaut Program. Yi cited personal reasons for quitting, but has been studying for an MBA in the US since 2012. You can read more about her work and reasons for leaving in articles from Australia Network News and abc News.
