Physics World Stories Podcast

Here at Physics World, we love talking about popular-science books. Indeed, we enjoy it so much that we braved the cold, not to mention a sore throat and cracked ribs (you’ll have to listen to find out more!), to share our thoughts on a few of the year’s best popular-physics books in a special edition of our podcast. As is becoming a tradition, this chat was hosted by our regular podcast presenter and producer Andrew Glester, in his garden shed, where he can often be found musing about “science fiction, science fact and everything in-between” for his own podcast the Cosmic Shed. Despite the freezing December morning, we gathered in the shed with hot drinks, blankets and a pile of books, as we discussed some of the themes that link the year’s books, on what was a somewhat out-of-the-ordinary shortlist. Congratulations to all of the shortlisted authors on their fantastic books – tune in to the podcast to hear some words from our winner. We hope that everyone will find something to appreciate on this list, and hopefully we have given you a few ideas for some excellent holiday presents.

To say the past couple of years have been a whirlwind for scientists engaged in gravitational-wave research would something of a cosmic understatement. After detecting its first gravitational waves in 2015, the LIGO experiment in the US went on to announce three more detections, all of them from the merger of two black holes. One of these was also detected by the Virgo experiment in Italy. This October Rainer Weiss, Barry Barish and Kip Thorne shared the shared the Nobel Prize for Physics for their pioneering contributions to the field and to the LIGO detector itself. Less than two weeks after the Nobel announcement, astronomers gathered at the Royal Society for the announcement of arguably the most significant breakthrough of all. The merger of two neutron stars was observed by the LIGO–Virgo collaboration, while gamma rays from the same event were picked up by the Fermi Gamma-ray Space Telescope. This prompted the global astronomical community to point up to 70 different telescopes and detectors around the world, and in space, at the origin of the signals in a distant galaxy – building a detailed picture of the collision and its aftermath. Glester was at that latest announcement at the Royal Society to soak up the atmosphere and learn all about multimessenger astronomy. Among the people he met was the Astronomer Royal Martin Rees, whose CV also includes terms as president of the Royal Society and the Royal Astronomical Society. Rees hails the latest result as “sociologically very important” because it demonstrates international collaboration between teams of scientists and engineers to achieve measurements of phenomenal precision. “It illustrates how astronomy is a very broadly based international and multi-technique subject,” he says. As the editor of physicsworld.com, Hamish Johnston, pointed out shortly after the Nobel prize announcement, we should not forget that for millennia, humans could only see visible light from the cosmos. It is only during the last century that we have been able to view the universe across much more of the electromagnetic spectrum – as well as through the arrival of high-energy particles such as cosmic rays and neutrinos. Adding gravitational waves to the mix now brings a new way of seeing the heavens that could reveal astronomical events that had been beyond the view – and even beyond the imagination – of astrophysicists. For a more in-depth look at the significance of these latest discoveries, take a look at Multimessenger Astronomy by Imre Bartos of the University of Florida and Marek Kowalski of Humboldt University and DESY. Part of the Physics World Discovery series, this free-to-read ebook explores the scientific questions surrounding these new messengers and the detectors and observational techniques used to study them. It also provides an overview of current and future directions in the field. Neutron-star collision artwork courtesy of the University of Warwick and Mark Garlick

2017 marks a couple of important anniversaries for the astrophysics community at Jodrell Bank. First, it is the 60th anniversary of the first light of the Lovell Telescope, which was the largest steerable dish telescope in the world (it is still the third largest). Second, it is the 50th anniversary of the first detection of pulsars being made by Dame Jocelyn Bell Burnell who was then a PhD student at the University of Cambridge. The telescope takes its name from Sir Bernard Lovell who founded the Jodrell Bank Observatory in 1945. Over the decades, this astrophysics hub has been a valuable tool for studying various astrophysical objects and it even played a role in tracking events during the Space Race. Today it is the HQ of the Square Kilometre Array, a distributed telescope array that promises to usher in a new era in radio astronomy. In recent years, Jodrell Bank has also developed a significant science-outreach programme, including the Jodrell Bank Discovery Centre, which opened in 2011 and now attracts thousands of visitors every year. The Blue Dot Festival is an extension of this and has been graced by music acts including Elbow, Sigur Rós and the Flaming Lips. The festival also features the winning work of the COSMOS art–science project, a collaboration between Jodrell Bank, Blue Dot Festival and the arts organization Abandon Normal Devices. This year’s winning artist was Daito Manabe from Tokyo, an audiovisual artist whose specialisms include the visualization of data. Among his previous collaborators is the Icelandic popstar Björk. In this latest project, Manabe collaborated with astrophysicists at Jodrell Bank to transform pulsar data (live and archival) into sounds and images projected onto the Lovell dish. In this podcast, Glester experiences the event and discusses the project with Manabe. You can also hear what the rest of the festival-goers thought of this otherworldly experience.
