About this listen

 Join mathematician Professor Hannah Fry and science creator Michael Stevens (Vsauce) as they dig into the weird scientific questions that often go unexplored. Welcome to The Rest Is Science, a show that sits in the fascinating space between what we think we know, and what we actually know. Why do we assume we understand things like time, randomness, or even gravity? Once you start questioning these familiar ideas, reality becomes astonishingly strange and completely fragile. Whether you're a lifelong science fan or just naturally curious, The Rest Is Science will change your perception of reality, and prove that the biggest questions are always the most fun.Goalhanger Mathematics Physics Science

    This Toothpick Contains Everything Ever Said
    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).

  • Why We Need Zip Lines On The Moon

    Why We Need Zip Lines On The Moon
    Apr 1 2026
    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)

    Two Infinities (And Beyond)
    Mar 30 2026
    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).

Hannah Fry is a fantastic presenter on radio and TV but barely gets a look in while Michael Stevens drones on. I tried several episodes that appealed but turned off before the end each time.

Interesting subjects, not enough Hannah
