Physics World Weekly Podcast

According to a recent white paper from the UK’s National Association of Disabled Staff Networks, 22% of working-age people in the UK have a disability compared to less than 7% of people working in science. At the upper echelons of science, only 4% of senior academic positions are filled with people with disabilities and just 1% of research grant applications to UK Research and Innovation are from researchers who disclose being disabled. These disappointing statistics are reported in “Towards a fully inclusive environment for disabled people in STEMM” and this podcast features an interview with one of its authors – the physicist Francesca Doddato. Based at Lancaster University, Doddato tells Physics World’s Michael Banks about the challenges facing scientists with disabilities – and calls for decision makers to engage with the issues and to remove barriers.

This episode of the Physics World Weekly podcast features Hannah Earley, a mathematician and physicist who is chief technical officer and co-founder of Vaire Computing. The company is developing hardware for reversible computing, a paradigm with the potential to reduce significantly the energy required to do computations – which could be a boon for power-hungry applications like artificial intelligence. In a conversation with Physics World’s Margaret Harris, Earley talks about the physics, engineering and commercialization of reversible computing. They also chat about the prototype chips that Vaire is currently working on and the company’s plans for the future.

Tracy Northup, a Professor at the University of Innsbruck specializing in quantum interfaces, and Peter Zoller, an Emeritus professor and renowned expert in quantum information, reflect on a century of quantum physics. They discuss Werner Heisenberg's groundbreaking legacy and the significance of Helgoland in the evolution of quantum mechanics. The conversation explores the future of quantum technology, the interplay between AI and physics, and the necessity for in-person collaboration in scientific discourse, amidst emerging innovations and ethical considerations.

In this episode of the Physics World Weekly podcast we explore the career opportunities open to physicists and engineers looking to work within healthcare – as medical physicists or clinical engineers. Physics World’s Tami Freeman is in conversation with two early-career physicists working in the UK’s National Health Service (NHS). They are Rachel Allcock, a trainee clinical scientist at University Hospitals Coventry and Warwickshire NHS Trust, and George Bruce, a clinical scientist at NHS Greater Glasgow and Clyde. We also hear from Chris Watt, head of communications and public affairs at IPEM, about the new IPEM careers guide. This episode was created in collaboration with IPEM, the Institute of Physics and Engineering in Medicine. IPEM owns the journal Physics in Medicine & Biology. This episode is supported by Radformation, which is redefining automation in radiation oncology with a full suite of tools designed to streamline clinical workflows and boost efficiency. At the centre of it all is AutoContour, a powerful AI-driven autocontouring solution trusted by centres worldwide.

This episode of the Physics World Weekly podcast features George Efstathiou and Richard Bond, who share the 2025 Shaw Prize in Astronomy, “for their pioneering research in cosmology, in particular for their studies of fluctuations in the cosmic microwave background (CMB). Their predictions have been verified by an armada of ground-, balloon- and space-based instruments, leading to precise determinations of the age, geometry, and mass-energy content of the universe.” Bond and Efstathiou talk about how the CMB emerged when the universe was just 380,000 years old and explain how the CMB is observed today. They explain why studying fluctuations in today’s CMB provides a window into the nature of the universe as it existed long ago, and how future studies could help physicists understand the nature of dark matter – which is one of the greatest mysteries in physics. Efstathiou is emeritus professor of astrophysics at the University of Cambridge in the UK – and Richard Bond is a professor at the Canadian Institute for Theoretical Astrophysics (CITA) and university professor at the University of Toronto in Canada. Bond and Efstathiou share the 2025 Shaw Prize in Astronomy and its $1.2m prize money equally. This podcast is sponsored by The Shaw Prize Foundation. Shrinivas Kulkarni, the 2024 Shaw Prize in Astronomy winner, has also appeared on the podcast. You can listen to that interview here.

Bob Coecke, chief scientist at Quantinuum, shares his groundbreaking approach to teaching quantum physics through diagrams, making it accessible to everyone. Joining him is Arjan Dhawan, a mathematics student who participated in a summer course aimed at teenagers. They discuss the urgency of understanding quantum concepts as technology evolves, the surprising success of students mastering complex ideas, and the benefits of visual learning in grasping challenging topics, all designed to engage a broader audience in the quantum revolution.

In this episode of the Physics World Weekly podcast I look at what’s new in the world of physics with the help of my colleagues Margaret Harris and Matin Durrani. We begin on Mars, where NASA’s Perseverance Rover has made the first observation of an aurora from the surface of the Red Planet. Next, we look deep into the future of the universe and ponder the physics that will govern how the last stars will fade away. Then, we run time in reverse and go back to the German island of Helgoland, where in 1925 Werner Heisenberg laid the foundations of modern quantum mechanics. The island will soon host an event celebrating the centenary and Physics World will be there. Finally, we explore how neutrons are being used to differentiate between real and fake antique coins and chat about the Physics World Quantum Briefing 2025.

James Wootton, Chief Scientific Officer at Moth Quantum, shares his insights on merging quantum computing with creative fields. He discusses how artists, musicians, and game designers can leverage specialized quantum software to revolutionize their work. Wootton emphasizes the unique advantages of quantum systems in procedural generation for games, enhancing creativity through probabilities. He also highlights the vital role of storytelling and public engagement in making quantum concepts accessible, demonstrating the fusion of technology and artistry.

Nadya Mason, Dean of the Pritzker School of Molecular Engineering, dives into how molecular engineering is revolutionizing quantum computing, sustainability, and biomedical technologies. Jeffrey Spangenberger, leader of the Materials Recycling Group at Argonne National Laboratory, discusses the intricacies of battery recycling and the innovative methods being developed for a more sustainable future. Together, they explore the potential of cutting-edge science to create a circular economy and advance technologies that address global challenges.

This episode of the Physics World Weekly podcast features the Nobel laureate Ferenc Krausz. He is director of the Max-Planck Institute of Quantum Optics and a professor at LMU Munich, both in Germany, and CEO and scientific director of the Center for Molecular Fingerprinting in Budapest, Hungary. In a conversation with Physics World’s Tami Freeman Krausz talks about his research into using ultrashort-pulsed laser technology to develop a diagnostic tool for early disease detection. He also discusses his collaboration with Semmelweis University to establish the John von Neumann Institute for Data Science, and describes the Science4People initiative, a charity that he and his colleagues founded to provide education for children who have been displaced by the war in Ukraine. On 13–14 May, The Economist is hosting Commercialising Quantum Global 2025 in London. The event is supported by the Institute of Physics – which brings you Physics World.
