Is 100 Better Than 101?
01 nov · 45 min
Is 100 really such a special number? Or have we spent thousands of years getting excited about something completely arbitrary?
To celebrate the 100th episode of The Rest Is Science, Professor Hannah Fry and Michael Stevens (Vsauce) go head-to-head in a mathematical showdown: which is the better number, 100 or 101?
It sounds like a simple question, but the answer takes them from the strange history of counting, to the psychology of numbers, the mathematics of primes and the possibility of communicating with alien species.
Why do we find round numbers so satisfying? Would 100 mean anything if we'd evolved with 9 fingers? And is there a single number that’s fundamentally special, regardless of the counting system we use?
Can Hannah and Michael settle the debate once and for all? Or is the most ‘important’ number of all one they haven't even considered yet?

What Are These Unsettling Sounds?
29 okt · 32 min
Some of the most creepy sounds ever recorded aren't from horror films. They're real.
From mysterious noises from the deepest parts of the ocean to the eerie voices of people who died more than a century ago, the world is full of sounds stranger than anything we could dream up.
But what on Earth is making them?
In this Halloween special of The Rest Is Science, Professor Hannah Fry and Michael Stevens (Vsauce) listen to some of the world's most mysterious and unsettling recordings, attempting to identify their origins and uncover the surprising science behind them.
They travel back to 1860 to hear a voice that was never intended to be heard again, investigate a bizarre underwater noise that baffled scientists for a decade, and encounter a sound so strange that Hannah suspects it might have come from outer space.
Turn up the volume, put on your headphones, and see how many you can identify…before Hannah does.

Earth’s Tilt Makes Time Slippery
25 okt · 53 min
A sundial can be almost 16 minutes fast in November and 14 minutes slow in February, yet there's nothing wrong with it. So why does the Sun, our oldest timekeeper, disagree with the clock on your wrist?
In this episode, Professor Hannah Fry and Michael Stevens (Vsauce) explore the equation of time - the strange relationship between Earth's tilt, its orbit around the Sun and the way we measure our days.
Why does a day last 24 hours? Has it always been that way? And how can a piece of ancient coral reveal that time itself has changed?
To find out, Hannah and Michael investigate an ingenious sundial that appears to correct its own mistakes, and discover the extraordinary places on Earth where shadows disappear completely.
Along the way, they explore why sailors relied on the stars, the Moon's remarkable journey across London's sky, and the curious fact that the Pacific Ocean is so enormous it meets itself on the other side of the world.

What Happened When We Stopped Squatting?
21 okt · 38 min
In many parts of the world, people rest in a deep squat every day. In others, most adults can barely get down there. So what’s going on? Hannah Fry and Michael Stevens dig into the history of squatting and why the ability to squat differs so much between cultures.Plus, your questions: What happens to the air pressure inside a car when it goes round a bend?

Mathematicians Are The Canary Down The AI Coal Mine
18 okt · 1 u 7 min
OpenAI claims a swarm of AI agents has solved the Navier-Stokes problem, one of the hardest unsolved questions in mathematics, with a $1 million prize attached. Then it released more than 700 more mathematical manuscripts, including claims touching the Riemann hypothesis, faster than anyone can check them. Mathematicians are not happy, and the reason goes far beyond the money.
In this episode of The Rest of Science, mathematician and fluid dynamicist Hannah Fry takes Michael Stevens through the equations that describe everything that flows, from the blood in your veins to a rocket leaving the atmosphere. Then she tells him why this story has turned the vocation of mathematics upside down.
Ten thousand AI agents. Millions of messages. One tiny term in the equation that nobody wanted to look at, until it unlocked the problem. But did AI really solve a million dollar problem? Why are some mathematicians accusing the models of stealing their work? And how might a proof that is completely correct be the least satisfying result in the history of maths?
Along the way, Hannah un-mixes a glass of dye with nothing but corn syrup and patience, and the pair ask what happens to curiosity when the answers arrive faster than the understanding.

The Right Way To Open A Shaken Soda Can
14 okt · 38 min
A can of fizzy drink has been violently shaken. The pressure is building, the bubbles are ready to erupt, and Michael Stevens is about to open it. But Hannah Fry has a trick up her sleeve. Can a few taps really prevent an explosion?This week on The Rest Is Science, Hannah and Michael begin with the surprisingly complicated physics of carbonation before tackling a much bigger question: can we really trust science?From the replication crisis and scientific studies that fail to stand up to scrutiny, to the strange incentives that shape what gets published, they explore why even respected scientific discoveries can turn out to be wrong...and why that might not be such a bad thing.Along the way, they investigate whether Archimedes really could have moved the Earth with a long enough lever, why aircraft are designed to withstand enormous pressure changes, and what happens when we lose our curiosity.Plus, an unexpected discussion about nuns, the dangers of absolute certainty, and why asking questions might be one of the most important things we can do.-------------------"For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://cancerresearchuk.org/restisscienceCancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Something Weird Is Going On With Placebos
11 okt · 50 min
For the past few decades, something strange has been happening in clinical trials. Painkillers aren't getting worse, but the placebos they're tested against appear to be getting better.
In one landmark study, the advantage of pain medication over placebo shrank from 27.3% in 1996 to just 8.9% in 2013.
Even stranger? This trend was found almost entirely in American trials.In this episode of The Rest Is Science, Professor Hannah Fry and Michael Stevens (Vsauce) investigate the extraordinary science of the placebo effect;
how our expectations influence pain, why belief can change the way our bodies respond, and what this means for the future of medicine.
Why does the way a treatment is presented matter so much? And how can simply expecting something to hurt actually make it hurt?
But the placebo effect doesn't stop at medicine. From pedestrian crossing buttons that do nothing to the surprising psychology of road safety, Hannah and Michael explore just how easily our expectations can shape our experience of the world.

Why Do We Turn on Innocent People?
04 okt · 51 min
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.

Hacking The Kendama With Physics
30 sep · 41 min
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.

Why Do We Like Staring Into Fire?
27 sep · 59 min
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.

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.

The Fluid Dynamics of Fountain Pens
23 sep · 1 u 5 min
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?

Dying In Space, Trapped Water, and What's Hidden In Pi?
20 sep · 49 min
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.

How Codes Were Used To Hack The Telegram Business
16 sep · 57 min
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.

Why Your Body Needs Gravity
13 sep · 43 min
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.

The Threshold of Human Sensation
06 sep · 55 min
What is the smallest thing you can possibly feel?
Michael Stevens and Professor Hannah Fry journey through varying levels of perception, from the faintest touch on skin to the faintest trace of flavour and odour, and on to the remarkable question of whether the eye can register a single particle of light.
This is an exploration of human senses at their most sensitive, blending physics and neuroscience with everyday experience to reveal where our biology draws the line between nothing and something, and what about emotion... how do we feel those?

The Scale of the Universe
02 sep · 49 min
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.

Why Loud Chewing Makes You Angry
30 aug · 50 min
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.

How Does Language Change What You Smell?
26 aug · 46 min
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.

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.

Space Elevators, Skyhooks, and Space Fountains
23 aug · 1 u 6 min
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!

Bizarre Watches and How They Work
19 aug · 54 min
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?

Why Your Brain Thinks You're Full (Even When You're Not)
16 aug · 47 min
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. What might this reveal about the biology of wanting itself, and how much control do any of us really have over what we crave?-------------------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-scienceCancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

The Lake At The North Pole That Stops Europe From Freezing
12 aug · 47 min
When you picture the North Pole, you probably imagine a vast, frozen expanse of floating sea ice. But hidden deep beneath the surface of the Arctic lies something incredible: a massive, churning reservoir of nearly freshwater, suspended right in the middle of a saltwater ocean.
In this episode of The Rest Is Science, Professor Hannah Fry and Michael Stevens (VSauce) explore the hidden hydrodynamics of the Arctic. Fresh off a real-world scientific expedition to the sprawling ice sheets of Greenland, Hannah shares firsthand accounts of the colossal forces currently reshaping our polar regions. Together, they unpack the bizarre physics that allow a gigantic freshwater lake to form beneath the Arctic ice.

The Science of Putting Sunglasses on The Sun
09 aug · 1 u
Why does the cartoon Sun always wear sunglasses? And how big would a real pair need to be?
Hannah Fry and Michael Stevens investigate space mirrors, Reflect Orbital and solar eclipses to find out.
Starting with a pencil held at arm’s length, they use the Sun’s angular diameter to calculate how big a pair of solar sunglasses would need to be for one eye, two eyes, everyone in London and eventually the entire planet.
Their hypothetical answer is a strange structure more than a million kilometres wide, positioned deep in space. Entirely practical. They compare its extraordinary scale with NASA’s Parker Solar Probe, the real spacecraft flying closer to the Sun than anything ever built, before using Lagrange points to work out where their creation could possibly go.
But could putting something between Earth and the Sun ever be useful?
Real proposals for space sunshades and climate geo-engineering suggest that blocking a small fraction of sunlight could help cool the planet. Moving from shade to reflection, they revisit Soviet attempts to reflect sunlight onto Earth at night and explore how Reflect Orbital’s Earendil 1 space mirror experiment might one day extend solar energy beyond daylight hours.
That leads them to the strange physics of light itself. Photons can push solar sails despite having no rest mass, revealing why E=mc² is only part of the full energy momentum equation from special relativity.
Finally, there is the optical phenomenon known as the Arago spot to contend with. It helps explain why NASA’s starshade concepts, future technology designed for hunting exoplanets, look like enormous sunflowers.

Why Is It A Colour Wheel & Not A Line?
05 aug · 47 min
Colour wheel or colour line? Light itself runs in a straight line from red to violet, yet every colour theory chart bends that spectrum into a circle and the reason has nothing to do with physics.
Professor Hannah Fry and Michael Stevens (VSauce) dig into why human vision refuses to see colour the way light actually behaves, tracing the visible light spectrum from one end to the other and asking where all the "missing" colours, like magenta and purple, actually come from if they don't exist on that spectrum at all.
It turns out the colour wheel is less a description of light and more a diagram of a workaround your brain performs constantly.

Why Lithium Batteries SUCK
02 aug · 54 min
Can Hannah convince Michael that the lithium-ion battery is one of our most overrated inventions to ever happen?
Hannah makes her case using a surprising energy source hidden in your fridge, a bell in Oxford that's been ringing since 1840, and a metal that is useful… but prone to bursting into flame from the inside out.
Tracing the battery's strange history, from a twitching dead frog to the executed man who helped inspire Frankenstein.
But the real point runs deeper: we don't have an energy problem, we have a storage issue, and until we crack it, the clean energy future stays just out of reach.

What Happens Inside Earth's Forbidden Zones?
29 jul · 46 min
What grows in the spaces humans are forced to abandon?Hannah brings Michael an actual piece of barbed wire from the Korean Demilitarised Zone, one of the most heavily fortified and forbidden borders on Earth, and it sends them somewhere unexpected.
From deserted no man's land and radioactive exclusion zones to remote islands that most of humankind has quietly agreed to leave well alone, they explore the surprising ways life adapts to the damage we leave behind.Plus your questions: the scientific fact that scared Michael most, where tectonic plates actually go when they collide, and a very good would you rather.

Did the world really end in 2012?
Not with fire, meteors or an ancient Mayan prophecy, but Professor Hannah Fry and Michael Stevens ask whether something just as profound took place instead.
Together they unravel how one of the biggest myths in history took hold and why the Maya were unable to accurately predict the apocalypse. But they also delve into why, according to Michael, 2012 was the year an old world was discarded and a new one began to emerge.
It was, afterall, the year a novel technology became unavoidable and we began to abandon a shared culture for millions of fragmented realities.
Along the way they also explore the science of confirmation bias, why humans are fascinated by the end of the world, and whether technology has made us less connected...or reconnected us in a different way.
