    The Barf Bag Episode
    Apr 29 2026
    What can a humble airplane sick bag teach us about physics, engineering, and the limits of the human stomach; And why are there people out there collecting thousands of them? Professor Hannah Fry and VSauce’s Michael Stevens turn an unlikely holiday prompt into a surprisingly rich exploration of flight. From the biology of motion sickness to the physics of turbulence, and from exploding crisp packets to next-generation aircraft design, they unpack how flying messes with your body and how science has made it (mostly) better. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    Alan Turing’s Final Theory Was About Leopards
    Apr 27 2026
    How does a perfectly symmetrical ball of cells become an animal, with a head, a tail, and complex zebra or leopard like patterns? In this episode, we dive into the mind bending science of how order emerges from chaos, guided by an unexpected genius: Alan Turing. From leopard spots and human embryos to crime hotbeds, Hannah and Michael discover the hidden mathematical rules shaping life itself…and the ethical dilemmas that come with them. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  • The Reasoning Test Psychologists Still Can't Explain

    The Reasoning Test Psychologists Still Can't Explain
    Apr 20 2026
    Why do almost all of us struggle with a simple reasoning test, yet get it right the moment it’s about a pint in a pub? This week, Professor Hannah Fry and Michael Stevens take on the Wason Selection Task, one of the most intensely studied problems in the history of psychology. They unpack why a rule involving letters and numbers can feel strangely difficult, while the exact same logic becomes immediate and instinctive when it’s about people, rules, and catching someone out. From counterexamples and conditional statements to confirmation bias and the limits of human reasoning, they reveal why we rarely look for what proves us wrong. Along the way, they tackle a bigger question: did reasoning evolve to uncover truth, or simply to help us get along? ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    The Elegant Laminar Flow Of Moroccan Tea
    Apr 15 2026
    Does a teapot secretly hold the laws of physics? And what do soap, sugar and mint have to do with the perfect cup of tea? Whilst in Morocco, Professor Hannah Fry takes Michael Stevens (VSauce) into the surprising science of mint tea, from foamy bubbles that trap desert sand to the elegant S-shaped spout that appears to solve some of the hardest problems in fluid dynamics. Plus, your questions, including whether rising sea levels could change how your eggs boil, and just how much of Earth humans have actually touched. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  • Science Is (Literally) Cool

    Science Is (Literally) Cool
    Apr 13 2026
    Is the kitchen home to some of the most extraordinary technology humans have ever invented? Professor Hannah Fry and Michael Stevens explore the science of everyday appliances, from the strange physics of coldness to the wartime origins of the microwave. They explore how humanity learned to trap 'coolth', beam heat into leftovers, and turn the most ordinary room in the house into a high performance laboratory! From ice merchants and exploding eggs to magnetrons and magnetic fridges, this is the surprising story of the science hiding in plain sight. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

    Are There More Raindrops In Clouds Or Data In THE Cloud?
    Apr 8 2026
    Does "the cloud" hold more data than a clouds hold raindrops? Can a new organ literally rewrite your personality? Professor Hannah Fry and Michael Stevens, VSauce, weigh our massive digital servers against a standard downpour, before unpicking the biology of transplant patients suddenly waking up with entirely new cravings. Michael also has a new Curiosity Box coming featuring an altertative periodic table disguised as a snail pin badge to showoff to Hannah. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

  • This Toothpick Contains Everything Ever Said (Infinity Part 3)

    This Toothpick Contains Everything Ever Said (Infinity Part 3)
    Apr 6 2026
    What happens when you finally reach the end of forever? And what exactly is the difference between Omega and Aleph-null? Professor Hannah Fry and Michael Stevens (VSauce) return for the final (possibly not) chapter of our infinity series, unpicking the frankly absurd mechanics of multiple infinities. They reveal how mathematicians don't just measure the endless void, but actively organise it, exploring the bizarre gap between the sheer size of a boundless set of numbers and its actual order. Following Georg Cantor's mathematical meltdown, this episode tackles the mind bending rules of the infinite, why Aleph-null is just the baby of the infinite family, and how jumping to Omega requires a complete rewiring of human logic. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).
