A TEDx train wreck?

Calm before the storm – the view of CERN from Robert P Crease’s bedroom window as he tries desperately to shave a final two minutes off his TEDx talk.

By Robert P Crease in CERN, Geneva

On Sunday morning I arrived at CERN to find workers putting finishing touches on a huge tent where the lab will host its TEDx event on Wednesday, and its 60th anniversary festivities next week.

“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

Pyramid power: this lovely pyramid has nothing to do with postdocs. It is model of a much larger  Sierpinski tree that can be found on London’s South Bank.

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.

A day in the life of CERN’s director-general

All in a day’s work. (Courtesy: CERN)

By Rolf-Dieter Heuer, Geneva

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.

Is desperation for new physics clouding our vision for new colliders?

By Hamish Johnston

This month marks the 60th anniversary of CERN and to kick-off our coverage here at physicsworld.com, I’m highlighting an essay on the future of collider physics that has just been written by Nobel laureate Burton Richter called “High energy colliding beams; what is their future?“.

Richter shared his 1976 Nobel prize with Samuel Ting for their independent discoveries of the J/ψ meson. He knows his particle colliders, having helped to design and build the world’s first collider in the late 1950s at Stanford University and later directing the Stanford Linear Accelerator Center for 15 years.

Richter believes that the international community is not facing up to tough decisions that must be made about what to do when the Large Hadron Collider (LHC) is retired sometime in the early 2030s. He thinks that “the perspective of one of the old guys might be useful”.

Planning the next huge collider involves the co-operation of three main groups of physicists: those who design and build the accelerators; those who design and build the experiments; and the theoretical physicists who work out what the experiments are looking for. Richter thinks that this is not going well at the moment.

By Hamish Johnston

Bad Boy of Science” Sam Gregson and colleagues are organizing an evening of physics-related comedy at CERN in Geneva on Friday 13 June. “LHComedy: No Cause for ConCERN” will kick off in the CERN Globe at 19:30 and is billed as “a fantastic and innovative new way of presenting the work going on at CERN and engaging with the public”. The line-up from CERN includes Canadian PhD student Nazim “License to Thrill” Hussain, quantum diarist Aidan “The Mole” Randle-Conde and Cat “Schrödinger” Demetriades. You can watch last year’s comedy extravaganza from CERN here. Others involved in the project are Clara Nellis, Alex Brown, Hugo Day, Claire Lee and Rob Knoops.

Seven lessons from Sean Carroll

Sean Carroll in full flow at the 2014 Cheltenham Science Festival.

By Matin Durrani in Cheltenham

I made the short journey yesterday from Bristol to the regency spa town of Cheltenham, which this week is hosting its annual science festival. One of the largest such events in the UK, it’s been running since 2002 and has a packed programme of A-list speakers and topics ranging from genetics to geology, from cocktails to cake, and from the human brain to the Higgs boson.

My main reason for attending the festival, though, was to meet Caltech physicist Sean Carroll, whose book about the search for the Higgs boson (called The Particle at the End of the Universe ) was picked by Physics World last year as one of our top 10 books of 2013. Carroll was in the Gloucestershire town to give a one-hour talk about the Higgs, although the festival organizers were clearly working him hard as he also spoke in separate lectures on dark matter and dark energy, and on his role as a science adviser to Hollywood. (Carroll’s worked on films including Thor, Avengers Assemble and TRON: Legacy and even played a tiny role on TV’s The Big Bang Theory – stay tuned for more on that in our upcoming audio interview with him.)

CERN gets set for LHC restart

Taking it lying down: an engineer working on the CMS detector at CERN.

By Michael Bishop in CERN, Geneva

As CERN ramps up its preparations for “Run 2″ of the Large Hadron Collider (LHC) at the start of 2015, many are wondering where the next big discovery will come from and whether it will emulate the success, and popularity, of the discovery of the Higgs boson in 2012.

There appears to be no hangover from that landmark event and a genuine excitement among the scientists at CERN, which I witnessed first-hand earlier this week during a two-day tour of CERN’s facilities organized by the UK’s Science and Technology Facilities Council (STFC).

Many of the UK-based scientists that I spoke to during the tour showed a remarkable enthusiasm for the experiments they were working on and confessed to expecting similar, if not bigger, discoveries when the particle collider starts smashing protons together at higher energies.

Intelligent life on a doughnut, how cats and skiers spin, a marriage made at CERN and more

By Hamish Johnston

There’s definitely an educational vibe to this week’s picks from the Red Folder, which begins with Tanner Higgin’s selection of “Five apps that test your physics skills“. Writing on Mind/Shift, a website based in California and dedicated to learning, Higgin highlights Crayon Physics Deluxe, which allows users to draw physical objects and then let gravity and other physical effects take over. Also featured is Amazing Alex, which allows users to combine more than 30 different household objects to create fantastical Heath Robinson/Rube Goldberg contraptions.

Join CERN’s scavenger hunt

Can you spot all 20 or so LEGO figurines in the CERN computing centre?

By Michael Banks

You may remember that late last year CERN teamed up with Google Street View to allow users to go on a virtual tour of the lab, including 12 km of the 27 km Large Hadron Collider (LHC) tunnel plus the caverns that house the ATLAS, CMS, LHCb and ALICE experiments.

This involved Google‘s Zurich team spending two weeks at CERN in 2011 photographing the LHC using a “Street View Trike” – a specially created camera-mounted bike.

Well, what we didn’t known then was that Stefan Lüders, CERN’s computer security officer, had decided to stash about 20 LEGO figurines around the CERN computing centre before the cameras rolled.
