  • The Reasoning Test Psychologists Still Can't Explain

    The Reasoning Test Psychologists Still Can't Explain
    2026/04/20
    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

    The Elegant Laminar Flow Of Moroccan Tea
    2026/04/15
    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
    2026/04/13
    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?

    Are There More Raindrops In Clouds Or Data In THE Cloud?
    2026/04/08
    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

    This Toothpick Contains Everything Ever Said
    2026/04/06
    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).

  • Why We Need Zip Lines On The Moon

    Why We Need Zip Lines On The Moon
    2026/04/01
    Why would a zip line be the best form of transport on the Moon? Why exactly can your feet still feel other textures right through your socks? Hannah and Michael tackle the spectacular physics of extreme commutes and everyday biomechanics. They unpick the orbital chaos and terrifying vacuum of space, proving why a lunar theme park ride is essentially a brilliant, fiery death trap. Back down on Earth, they dive into the hypersensitive neurology of touch, revealing how your brain decodes microscopic vibrations through layers of cotton to perfectly map the floor beneath you. To top it all off, Hannah shares her very old school, steam punk esq, mechanical calculator. ------------------- 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).

  • Two Infinities... And Beyond (Infinity Part 2)

    Two Infinities... And Beyond (Infinity Part 2)
    2026/03/30
    Why were the ancient Greeks absolutely terrified of the infinite? How did a boundless mathematical concept start bitter historical feuds? And what happens to reality when you realise that some infinities are actually bigger than others? Professor Hannah Fry and Michael Stevens (VSauce) plunge back into the mind-bending history of infinity, tracking the spectacular panic it caused across the centuries. From individuals trying to mathematically contain it, to others wrestling with its endless quantities, they explore how the greatest thinkers clashed over the universe's most impossible idea. The chaos truly peaks with Georg Cantor, the man who completely broke maths by proving that infinity comes in different sizes. Building on part one, where Hannah and Michael desperately tried to figure out if this strange beast is an actual number or just a brilliant hallucination, this second episode looks at the human cost of counting forever. ------------------- 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).
