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”.

Today I was planning to write a cheerful blog celebrating the first circulating proton beams in the Large Hadron Collider (LHC), but sadly the particle gods are not smiling down on CERN this week. Accelerator physicists in Geneva have identified an electrical fault in one of the collider’s magnet circuits and plans to restart the giant machine this week have been put on hold – possibly for several weeks.

The south-west of England is not exactly known for its sunny skies at this time of year, so many of us in Bristol – home to Physics World HQ – had steeled ourselves to miss out on today’s solar eclipse, which coincidently is on the first day of spring. So, we were rather overjoyed when the Sun shone through the sparse cloud cover for nearly an hour of the celestial treat. While today’s eclipse was technically visible to anyone in North Africa and Europe, totality was only visible to those lucky few who happened to be on the Faroe Islands (where it was actually cloudy for most of the time) and in Svalbard in northern Norway. Here in Bristol, the eclipse peaked at about 9.30 a.m., when 87% of the Sun’s light was blocked by the Moon.

On Friday, our old friend the Moon will swing by to remind us that she’s not just there to reflect the Sun’s light; she can sometimes block it out too. A total solar eclipse will be visible to those lucky few people living in the Faroe Islands or the Norwegian archipelago of Svalbard. Many others across Europe, North Africa and Russia will be treated to the (almost as good) spectacle of a partial solar eclipse.

While visiting CERN, the world’s biggest particle-physics laboratory, it’s easy to get swept up by the excitement of the Large Hadron Collider and its detectors, especially in the run up to it being switched back on in the coming weeks. But CERN is also host to a variety of other equally exciting experiments that probe some of the biggest unanswered questions in science, such as the experiments that probe the unwieldy world of antimatter. Indeed, CERN’s antimatter programme has received considerable attention in the past, especially thanks to the now-famous book (and later, film) Angels and Demons, where some antimatter was supposedly stolen from the laboratory and used to build a bomb! Suffice to say, antimatter is of interest to physicists and the public alike and so I caught up with physicist Jeffrey Hangst, who is spokesperson of the Antihydrogen Laser Physics Apparatus (ALPHA) experiment, which I also had the chance to visit.

Like all good publications, Prospect has a strapline about itself – “the leading magazine of ideas”. Physics World is also about ideas, although sadly our magazine, great though it is, doesn’t have adverts for Cartier watches, Embraer executive jets or the Taj Exotica Resort & Spa in the Maldives as Prospect does. Clearly, some people with ideas have more money to spend than others.
I was kindly invited last week by the deputy editor of Prospect, Jay Elwes, to an event he hosted at the magazine’s headquarters in central London. The event featured the University of Oxford physicist Frank Close, who has just published a new book on the life and times of Bruno Pontecorvo. Close was on hand to discuss the key themes of the book, which is entitled Half Life: the Divided Life of Bruno Pontecorvo. Elwes described the attendees as a “small, high-powered group”, including as it did Pauline Neville Jones, the former chair of the UK’s Joint Intelligence Committee and Jonathan Evans, the former director-general of the British security service MI5.

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!

This Sunday, as the world celebrates International Women’s Day, I’ll be thinking of some amazing women who had a huge impact on the world of physics, helping shape the field as we know it today. Indeed, yesterday I was at the Institute of Physics in London, attending a day-long conference on “The lives and times of pioneering women in physics” hosted by the Institute’s Women in Physics group along with its History of Physics group. While there were a host of interesting speakers at the event, undoubtedly the star of the day was French nuclear physicist Hélène Langevin-Joliot, granddaughter of one of the 20th-century’s most famous female physicists – Marie Curie.

Last month on a rainy grey morning in north-east England I headed to the Daresbury Laboratory as the SuperSTEM lab there celebrated the installation of its latest world-class microscope. Industrial and academic microscopists from around the world gathered for the inauguration, which was described as a “wedding for microscopists” because so many people from the tightly knit microscopy community were there. You can hear the excitement in the audio piece below, where SuperSTEM lab director Quentin Ramasse and other researchers at the event tell me their plans for the new instrument.

The March 2015 issue of Physics World magazine, a special issue about light in our lives that is now out in print, online and via our apps, contains a fascinating feature about an astonishing – and largely unknown – superpower that you perhaps don’t realize you have. It might sound bizarre, but using your naked eyes – and with no additional gadgets whatsoever – you can detect whether or not light is “polarized”. And in the video above, Louise Mayor, features editor of Physics World, tells you how.
