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.

It’s not often that classical physics and Post-Impressionist painters collide, but when they do the results can be enchanting and intriguing. In one of the latest TEDEd videos, Natalya St Clair has created a short lesson that looks at “The unexpected math behind Van Gogh’s Starry Night.” The video above looks at the enduring mystery that is the turbulence we see in any kind of flows in the natural world and how the human brain can recognize and actually make some kind of sense of the chaotic random patterns turbulence describes.
As pointed out in the video, famous physicists such as Richard Feynman and Werner Heisenberg have noted the complexity of turbulence, with Feynman describing it as “the most important unsolved problem of classical physics” and Heisenberg saying that “when I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first”. But is it possible that the undoubted genius and troubled painter that was Van Gogh perceived something more about turbulence in nature and is this most clearly represented in his most famous masterpiece – the evocative painting known as Starry Night? Watch the video to find out.

“The past is a foreign country: they do things differently there,” is probably the only famous sentence written by the English novelist L P Hartley. It also sums up nicely a collection of photographs of CERN in the 1960s and early 1970s showing among other things a jolly worker wearing a beret, scientists wearing white lab coats and ties, and a strange religious-like procession. There are also lots of photos of vintage kit, including one of those huge vacuum-valve-powered oscilloscopes (probably from Tektronix) that would be familiar to physicists of a certain age. My favourite photo is shown above. It was taken in 1965, when 3D data visualization was actually done in 3D! I believe that the collection was put together by CERN’s Alex Brown and you can enjoy looking at all 55 images in the collection here.

This year has been a special one for the CERN particle-physics lab near Geneva as it turns 60 years old. It was back in 1954 when the CERN convention was ratified by its first 12 member states and the European Organization for Nuclear Research was officially established.
The past few months have seen CERN celebrate in style with a whole host of symposia, meetings, plays, films, concerts and other events being held at the lab and at member states across Europe.
Indeed, researchers at CERN have had a lot to celebrate recently, following the discovery of the Higgs boson at the lab in 2012, and they will be hoping for yet more success when the Large Hadron Collider (LHC) switches on next year following a two-year upgrade and maintenance programme.
In the latest Physics World focus issue on “big science” we look at what has been going on at CERN during the shutdown as the lab gears up to hunt new particles beyond the Higgs boson. Once back online, the LHC will be generating even more data than in its previous run and this focus issue also investigates how researchers are going to deal with the huge volumes of information that will be generated at many upcoming facilities, as well the need to train the next generation of researchers to use them.

I’m fascinated by the interactions between science and culture, which is what led me to the Brooklyn Academy of Music (BAM), which was hosting the US première of a dance piece called Quantum that had previously debuted where it had been created, at CERN. The event was staged in a simple, black-box space, with the audience seated around a square floor in three rows with no proscenium. But it was an upscale black box, with elegant seating upholstered in a blue-and-gold metallic sheen. Four industrial lights were suspended from the ceiling by long cables.

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.

It’s great to go first.
Then you can actually listen to the other performances without fretting about your own. Somewhere near the middle of my TEDxCERN talk yesterday (Wednesday 24 September) I stopped being aware of the timer at my feet, began to have fun and left the stage at the end without even noticing whether I had exceeded my time limit. I made a brief stop backstage to lose my “Madonna” – a microphone that’s not on a neck clip or attached to a headset but extends out from an ear brace – then retook my seat in the front row.

On Tuesday morning I addressed 1300 empty chairs.
I was the first of several presenters yesterday at a dress rehearsal for the TEDxCERN event, which takes place this afternoon, Wednesday 24 September. The rehearsal was held in a huge tent specially constructed for this event, and for CERN’s 60th-anniversary celebrations next week. The programme will be broadcast live today starting at 1.30 p.m. CEST (GMT+2).
It isn’t easy, I discovered, to grab the attention of empty chairs. I stumbled over sentences and forgot to click my slides. Occasionally I felt on automatic pilot, and had the eerie experience of hearing myself speak with a half-second delay, as if I were listening to myself from the back of my head. I went a minute over time and also discovered a typo in a slide that I had viewed approximately a zillion times before. I was relieved to find I wasn’t the only one; some of those who followed, too, tripped over delivery or had trouble with slides.

All this week the people at CERN and in its member states will be celebrating 60 years of particle physics at the world-famous lab in Geneva. There is something for everyone to enjoy and here are a few highlights that we have picked out

“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.
