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).

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).

Ever wanted to squish a puppy just because it’s impossibly cute? Or felt absolutely certain you’ve lived this exact moment before? Hannah and Michael explore the bizarre, everyday glitches of the human mind, unpacking why our brains occasionally seem to short-circuit. They dive into the weird neurology of "cute aggression", or urges like thinking of throwing your phone off a bridge, to the jarring time-bending sensation of déjà vu to reveal how our grey matter manages overwhelming feelings and sudden memory misfires. ------------------- 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).

Have you stubbed your toe and shouted an unrepeatable word? Isaac Newton and Robert Boyle were two of the greatest minds in humanity. Did their egos and competition with one another hold them back or drive them onto huge breakthroughs? Professor Hannah Fry and Michael Stevens explore the bizarre neurology of vocalised pain, revealing how a good yelp actually acts as a biological off-switch for suffering and unearth if Newton was the biggest crybaby in science. Plus, Hannah gives us a behind-the-scenes look at her brand-new series exploring the cutting edge of Artificial Intelligence. ------------------- 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).

Botanically speaking, there is no such thing as a vegetable, so what exactly is sitting on your dinner plate? And if our culinary world is built on biological lies, which plant is actually the most vegetable like? Professor Hannah Fry and Michael Stevens tackle a chaotic intersection of linguistics, plant taxonomy, and nutrition, dismantling the arbitrary categories we use to organise our food, revealing that our supermarket aisles are a scientifically lawless wasteland. It is a strangely profound look at how human language struggles to categorise the natural world, proving that the things we eat every day are far weirder than we think with biological definitions that turn cucumbers and eggplants into fruits, and the nutritional benchmarks we use to invent the concept of a "vegetable" from scratch. ------------------- 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).
