This month’s episode of Physics World Stories features an interview with composer Amanda Lee Falkenberg with music from The Moons Symphony. Her creation takes listeners on an epic journey through the science and stories of the moons of our solar system.
The seven-movement symphony dramatises the geophysical features of Io, Europa, Titan, Enceladus, Miranda, Ganymede, before turning to our own Moon for two-part finale. In creating the work, Australian born Amanda Lee Falkenberg immersed herself in the scientific research and consulted many scientists and astronauts.
The Moons Symphony performed ..read more

Coke or Pepsi? Messi or Ronaldo? Taylor Swift or…well, without wanting to set the Swifties against Physics World, let’s just say there’s often a tribal element to who we support or the choices we make.
In the world of cosmology, one heated divide is whether you’re for dark matter or modified Newtonian dynamics (MOND). Both theories attempt to explain the discrepancies between the predicted gravitational effects in the universe and some of the actual observed motions of stars and galaxies.
In the latest episode of Physics World Stories, Andrew Glester speaks to two cosmologists on opposing side ..read more

In the latest Physics World Stories podcast, astrophysicist Emma Chapman is in conversation with host Andrew Glester about the history of radio astronomy. It’s a field that has always maintained a do-it-yourself ethic, with valuable contributions from people outside the established academic community.
Chapman, an astrophysicist at the University of Nottingham in the UK is the author of the popular-science book First Light: Switching on Stars at the Dawn of Time. Alongside her research, Chapman regularly visits amateur radio astronomy clubs and admires the technical expertise she encounter ..read more

Over the past half century, laser cooling has revolutionized atomic, molecular and optical physics. Laser cooling of atoms and ions has enabled dramatic leaps in the precision of atomic clocks, allowing new tests of fundamental physics and potential improvements in clock-based navigation via the Global Positioning System. Now it is also laying the foundations for quantum computing with atoms and ions.
In this episode of Physics World Stories, you can enjoy a vibrant tour through the history of laser cooling with Chad Orzel, a popular-science author and researcher at Union College in the US, wh ..read more

This episode of the Physics World Stories podcast features an interview with Kai Bird, co-author of the book that inspired the recent blockbuster film Oppenheimer, directed by Christopher Nolan. Winner of the 2006 Pulitzer Prize in Biography, American Prometheus: the Triumph and Tragedy of J. Robert Oppenheimer is an exploration of the brilliant and enigmatic physicist who led the project to develop the world’s first atomic weapons.
Oppenheimer is a fascinating but complicated character for a biographer to tackle. Despite excelling in his leadership of the Manhattan Project, Oppenheimer’s cons ..read more

Energy accounts for more than three-quarters of our greenhouse gas emissions globally each year. That’s not surprising, given the role of energy in almost every aspect of modern life. To stand any chance of hitting net zero climate targets, we need to accelerate the transition to greener forms of energy generation.
In this episode of the Physics World Stories podcast, Andrew Glester explores two novel forms of renewable energy generation, both with the potential to scale and not suffer from issues of intermittency.
First up, Nicol Kaplin speaks about SOLARIS, an ambitious ESA project investiga ..read more

In recent weeks the astrophysics community has been buzzing following the discovery that the universe appears to be filled with a background hum of gravitational waves. Using radio telescopes in the Africa, Asia, Australia, Europe and the US, several teams have noted the same thing: that gravitational waves leave a faint fingerprint in the signals received from pulsars within our galaxy. The discovery is another exciting breakthrough within multimessenger astronomy.
In this episode of the Physics World Stories podcast, Andrew Glester explores the implications of the new gravitational wave disc ..read more

Gordon Moore, the co-founder of Intel who died earlier this year, is famous for forecasting a continuous rise in the density of transistors that we can pack onto semiconductor chips. His eponymous “Moore’s law” still holds true after almost six decades, but further progress is becoming harder and eye-wateringly expensive to sustain. In this episode of the Physics World Stories podcast we look at the practicalities of keeping Moore’s law alive, why it matters, and why physicists have a critical role to play.
Right now, one of the key questions is whether computer hardware can keep up with the d ..read more

When discussing the capabilities of the latest AI chatbots, a physicist may argue: “Ok, they’re impressive at regurgitating texts that sound increasingly human. But we physicists don’t have much to worry about. It will be ages before the bots learn to grapple with physical concepts and the creativity required to do real physics!”
Such a view is almost certainly misguided. In a recent paper uploaded to arXiv, Colin West from the University of Colorado Boulder reported that the latest version of ChatGPT (built on GPT-4) scored 28 out of 30 on a test designed to assess students’ grasp of basic Ne ..read more

If you were awarded $3m prize money for your scientific excellence and hard graft, would you give it all away to strangers? That’s what the Northern Irish astrophysicist Dame Jocelyn Bell Burnell did in 2018 after winning the Special Breakthrough Prize in Fundamental Physics for her 1967 discovery of pulsars and her inspiring scientific leadership. She used the cash – topped up with more personal money from a separate prize – to launch the Bell Burnell Graduate Scholarship Fund, which supports PhD students in the UK and Ireland from groups under-represented in physics.
In this episode of the P ..read more
