The Rest Is Science – Détails, épisodes et analyse

What is gravity, really? Why do objects pull towards each other at all? And if Einstein 'fixed' Newton’s theory, why does gravity remain one of science’s biggest unsolved mysteries? A clumsy trip into a lamppost leads Michael and Hannah into a whirlwind tour of our changing understanding of gravity, from falling apples and making wormholes for ants, to the puzzles we still can’t crack. Why does time tick faster on a mountaintop than by the sea? Why are galaxies spinning in ways our equations can’t explain? And could an invisible particle finally reveal what gravity is made of? Join Professor Hannah Fry and YouTube educator Michael Stevens as they uncover the strange, unfinished story of the force that holds the universe together. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠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).

Is lava water, and could we have a delicious hot cup of it? Is ice really a rock, and not water? And, the age old question, is water wet? From the minerals that shape the taste of our favourite drinks, to the tiny isotopes that reveal where a person, or whale, has travelled, Professor Hannah Fry and Michael Stevens reveal the hidden life of H₂O. Along the way, they uncover why pure water can be deadly, how yesterday’s sewage might be fuelling the future, and discover that the water in your glass might be older than the Sun. Prepare to rethink the world’s most familiar liquid - it’s far stranger, rarer, and more extraordinary than you ever imagined. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit 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 humans the only creatures that shed emotional tears? If we are, what purpose do these tears really serve? If crying is so natural, why do we so often try to hide it? A single sob sends Hannah and Michael into an unexpected journey through the science and mystery of emotional crying, from the first tearful moments of infancy to the complex social signals behind adult weeping. Why do babies cry before they can speak? How do tears strengthen - or strain - our relationships? And what is the hormonal cocktail that makes “a good cry” feel so strangely comforting? Join Professor Hannah Fry and YouTube educator Michael Stevens as they uncover the strange, revealing story of the human tear: why we cry, what our tears communicate, and how this uniquely human response shapes the way we connect. ------------------- 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).

What happens when humanity dares to shout a cosmic “hello”? Could it help alien civilisations decode human mathematics, our DNA, the blueprints of who we are? And why did we blast the 3-trillion-watt message into the stars in the first place…only to never try anything like it again? This is the story of the Arecibo message. Welcome to The Rest Is Science: Field Notes. Every Thursday, Hannah and Michael rummage through their personal troves of scientific treasure and source discoveries that explain our understanding the universe, oddities that scramble our brains, objects that hint at forces we’ll never see...and a few things that are essentially just plain cool.

How did pages of mysterious “gibberish” sent from Madras find their way to one of Cambridge University’s most respected mathematicians? Were the strange formulas the work of a deluded mind - or breakthrough insights of an unknown genius?The author of that letter was Srinivasa Ramanujan.

What makes a simple brain-teaser about two identical swords one of the most deceptively tricky logic puzzles of the last century? And why has this seemingly innocent riddle fascinated mathematicians, programmers and puzzle-solvers for decades? First shared in recreational maths circles before spreading across classrooms and online forums, the “swords of truth” puzzle asks a disarmingly straightforward question — yet its solution reveals deep ideas about reasoning, information, and the limits of what we can deduce from what we’re told. Is the puzzle just a clever bit of misdirection, or a gateway into the foundations of logic itself? And why does a question about two swords feel so strangely relevant in an age of misinformation? Welcome to The Rest Is Science: Field Notes. Every Thursday, Hannah and Michael rummage through their personal troves of scientific treasure and source discoveries that explain our understanding the universe, oddities that scramble our brains, objects that hint at forces we’ll never see...and a few things that are essentially just plain cool.
