Description

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.

Why Do We Turn on Innocent People?
2026/10/04
Why do we turn on innocent people? A convincing story, a suspicious glance and suddenly everyone’s an armchair detective. But what happens when the crowd gets it completely wrong? Hannah Fry and Michael Stevens explore the psychology of false accusations, witch hunts and mob mentality, starting with Richard Jewell, the security guard hailed as a hero after the 1996 Atlanta Olympics bombing before becoming the target of a media storm. From the Salem witch trials and the Satanic Panic to internet detectives and social media pile-ons, they investigate how a hunch snowballs into certainty. Along the way: confirmation bias, beliefs that refuse to budge, and the famous Asch conformity experiments that show how easily we join the crowd, even when the crowd is obviously wrong. Plus, Michael tackles accusations that Vsauce’s Mind Field was faked, Hannah shares her own brush with conspiracy theories, and they ask why we’re so convinced we can spot a liar when the evidence suggests we’re barely better than a coin toss. It’s a journey through outrage, misinformation and our very human enthusiasm for pointing the finger. Because once people think you’re guilty, even defending yourself can look suspicious. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Hacking The Kendama With Physics
2026/09/30
Michael hands Hannah a kendama, the Japanese cup-and-ball toy, and asks her to land a single catch. Then he brings out one built for him by Adam Savage of MythBusters and explains why a heavier kendama is a completely different physics problem. A kendama looks like a children's toy. It is really a pendulum, a lesson in angular momentum and a catching problem borrowed from spacecraft docking. Michael and Hannah get into why the swing timing barely changes when the ball gets heavier, why the trick is to match the ball's velocity rather than grab at it, why bending your knees on the catch is doing real work, and why the paint finish on a kendama changes how it plays. Then Hannah and Michael take on your questions: what would actually happen if you flew into Jupiter and kept going, whether there is a mathematical way to swim faster, and which books they'd hand an adult who wants to get back into maths after school ruined it. ------------------- 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 Do We Like Staring Into Fire?
2026/09/27
What is fire, and why does watching it hold our attention in a different way from scrolling on your phone? Hannah Fry and Michael Stevens start with the science of a flame: why it glows, what its different colours reveal, and why fire is a series of chemical reactions rather than a single substance. Then they travel back to a time before wildfires could burn on Earth, and ask how early humans learned to use and make it. Could keeping a fire alive have helped our ancestors learn to plan and cooperate? And what happens when we replace the quiet pull of a hearth with the endless pull of a phone? From candle flames to early human history and the psychology of attention, this is the story of fire, the space it occupies in our history and lives. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

The Fluid Dynamics of Fountain Pens
2026/09/23
The wait is finally over: Hannah Fry introduces Michael Stevens to her beloved fountain pen collection and the beautiful physics behind how fountain pens work. From a £20 Lamy Safari to vintage Waterman and Montblanc pens, Hannah explains how capillary action, surface tension, air pressure and carefully engineered feeds control the flow of fountain pen ink. Michael tests the collection, chooses his favourite and discovers why the most expensive pen is not necessarily the nicest to write with. Then Hannah and Michael answer your questions: which words are terrible at their jobs, how do aeroplane wings actually generate lift, and which moment in history would they most like to witness? ------------------- 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).

Dying In Space, Trapped Water, and What's Hidden In Pi?
2026/09/20
Almost every human who has ever lived has one thing in common: they were born and died on Earth. Except for three people. Hannah Fry and Michael Stevens uncover the extraordinary story of Soyuz 11, the Soviet cosmonauts who became the only humans ever to die in outer space, and what their deaths meant for the future of human spaceflight.But that raises a bigger question: what exactly is trapped on Earth, and what can escape? Is the water left inside discarded plastic bottles being locked away forever? Is Earth itself slowly leaking water into space? Can you really trap a monkey simply because it refuses to let go of something shiny? And are your phone number, your name and every other possible sequence of numbers really hidden somewhere inside the digits of pi? From space exploration and the Soyuz 11 disaster to Earth's water, animal behaviour and one of mathematics' biggest unanswered questions, Hannah and Michael investigate what gets trapped, what escapes, and what might have been hiding in plain sight all 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).

How Codes Were Used To Hack The Telegram Business
2026/09/16
What if a single strange word could save you a fortune? In this episode Michael opens up a Victorian telegram code book and explores how users compressed long messages into brief coded words to outwit the per word charge of the telegraph system. Coded language turned everyday phrases about everyday events into something that looked like nonsense to outsiders, and why that secrecy was often a side effect of economy rather than espionage, and how operators learned to live inside this clipped new dialect of distance and delay. ------------------- 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 Your Body Needs Gravity
2026/09/13
Does space travel make astronauts younger? Professor Hannah Fry and Michael Stevens explore Einstein’s twin paradox, time dilation and NASA’s famous Twins Study with astronauts Scott and Mark Kelly. After Scott Kelly spent 340 days aboard the International Space Station, he returned milliseconds younger than his identical twin. But microgravity had also affected his eyesight, bones, blood, gut microbiome, body temperature, genes and telomeres. So what exactly happens to the human body in space, and which changes remain after astronauts return to Earth? In this episode, Hannah and Michael discover how deeply the human body depends on gravity. Along the way, they uncover why your head ages faster than your feet, what a 63 day cave experiment reveals about our sense of time, and whether future humans could ever truly adapt to life beyond Earth. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

The Scale of the Universe
2026/09/02
The scale of the universe stretches from the Planck length, the smallest scale physics can describe, to the observable universe, the largest thing we can see. Travel inward from one and outward from the other by powers of ten and they meet at something astonishingly familiar: the size of a human egg cell. Michael Stevens (VSauce) takes Professor Hannah Fry on a journey through powers of ten, from quarks and protons and DNA to bananas and pyramids and on to planets and galaxies, to explore where we sit in the scale of the universe. Along the way they ask whether the Planck length could be the universe's smallest pixel, whether reality might be a computer simulation and just how empty space really is. Plus, your questions: why our best ideas arrive in the shower, Wikipedia's strangest rabbit holes and Hannah corrects the record on whether Saint Augustine and Thomas Aquinas believed curiosity was a sin. ------------------- You can find the Reddit thread for scale of the universe here: https://www.reddit.com/r/TheRestIsScience/comments/1uycf3l/i_visualized_michael_scale_comparison_from_the And The Power Of 10 documentary here: https://www.youtube.com/watch?v=0fKBhvDjuy0 See some of Hannah & Michael's favourite Wikipedia pages here: - Osama Bin Laden The Elephant - https://en.wikipedia.org/wiki/Osama_bin_Laden_(elephant) - Death From Laughter - https://en.wikipedia.org/wiki/Death_from_laughter - Order Of Magnitude - https://en.wikipedia.org/wiki/Order_of_magnitude - Amedeo Avogadro - https://en.wikipedia.org/wiki/Amedeo_Avogadro - Guy Standing (Economist) - https://en.wikipedia.org/wiki/Guy_Standing_(economist) -Guy Standing (Actor) - https://en.wikipedia.org/wiki/Guy_Standing_(actor) ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Why Loud Chewing Makes You Angry
2026/08/30
The mukbang phenomenon is comfort viewing for millions, yet for others the sound of chewing, slurping and everyday mouth noises is enough to trigger instant anger, disgust and distress. Why do the sounds soothe one person and enrage another? In this episode, Professor Hannah Fry and Michael Stevens (Vsauce) explore misophonia, the misunderstood sound sensitivity that can turn everyday mouth sounds into powerful emotional triggers. 1 in 5 people in a UK study have reported a hatred of mouth sounds, but where does the problem lie, and can you train your brain to stop hating a sound, or is the person chewing next to you simply beyond forgiveness? Are the sounds themselves the trigger? Or is the structure of the human ear to blame? Perhaps, instead, the answer lies in a surprising connection between our brains and our jaws. To find out, Hannah and Michael trial a surprising trick that could offer genuine relief, and discover how changing what you see can completely transform your response to what you hear. Along the way, they investigate nails on blackboards, the frequencies used in acoustic weapons, the device designed to drive teenagers out of public spaces and the curious connection between misophonia, ASMR and the mukbang world itself. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

How Does Language Change What You Smell?
2026/08/26
In this episode of Field Notes, Professor Hannah Fry and Michael Stevens (Vsauce) begin with a Persian word for a smell Hannah cannot detect on a freshly washed plate. From the Sapir-Whorf hypothesis and Russian words for blue to emotions and identity, Hannah and Michael investigate how language may shape our experience of the world. Then, your questions. How fast would you need to throw a rock for it to escape Earth? What is the planet's escape velocity? Could it survive the atmosphere, or would it take something the size of the Chicxulub asteroid to make it out? How does soap kill germs? Why does bleach feel slippery on your hands? And can a scientific theory be completely wrong but still appear to work? Join them, as they explore linguistics, psychology, colour perception, space travel, bacteria, viruses and, of course, the scientific method. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Space Elevators, Skyhooks, and Space Fountains
2026/08/23
What is the fastest, cheapest and possibly worst way to get into space? Could a nuclear explosion launch a manhole cover beyond the Earth’s atmosphere? And could space elevators, skyhooks or launch loops one day replace rockets? In this episode, Professor Hannah Fry and Michael Stevens (VSauce) explore where space really begins, why orbit means falling forever, and how Newton’s cannon explains the motion of the International Space Station. They also interrogate the physics of the Kármán line, orbital velocity and geostationary orbit, before asking whether humans could ever climb a staircase to space, or catch a rotating skyhook into orbit. Plus, the far future fate of Earth, firing a bullet around the Moon, the true value of the Apollo Moon landing, the ethics of colonising Mars and whether the future of space exploration should belong to private companies or the public! ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Bizarre Watches and How They Work
2026/08/19
Michael Stevens keeps a small museum of unusual timepieces on his desk: a clock that runs backwards, a watch built to be read in complete darkness, and one whose entire face simply says "now." Each is a miniature experiment in the psychology of time, and each reveals something surprising about how our perception of time shapes the way we understand uncertainty and the world around us. The conversation then turns to logic and reasoning: how we make judgements, why we get things wrong, and whether thinking more carefully can help us make better sense of reality. It ends with your questions, including why so many of us are convinced we're simply "not maths people”. Is that belief itself, rather than any innate ability, the real source of our mathematical failure? ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Why Your Brain Thinks You're Full (Even When You're Not)

How did the Gila monster, a desert lizard that eats just five times a year, help unlock the science behind Ozempic, Wegovy and Mounjaro?In this episode of The Rest Is Science, Professor Hannah Fry and Michael Stevens (Vsauce) trace the strange journey from a molecule found in lizard venom to medicines reshaping diabetes and weight-loss treatment, exploring how GLP-1 helps regulate blood sugar, appetite and the hum of ‘food noise’.Early evidence suggests their effects may extend far beyond food, quieting cravings for alcohol and cigarettes, and even the urge to gamble.
