What Happens Inside Earth's Forbidden Zones?

Why Is It A Colour Wheel & Not A Line?

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

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. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ [https://⁠⁠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 Inside Earth's Forbidden Zones?

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.

It Wasn't A Hoax After All

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. ------------------- 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 [https://www.cancerresearchuk.org/our-research/rest-is-science].

Hack Dog Vision To Keep Your Bones Safe

Can you hide your skeleton from a dog? Would you want to know the day you’ll die? Has evolution ever come close to producing a real fire breather? Michael and Hannah test a T-shirt with a secret only humans can see, leading them into the strange world of colour vision, from colourblindness and tetrachromacy, to the remarkable eyes of the mantis shrimp. They also ask whether DNA could become the ultimate hard drive, visit a data storage mountain in Pittsburgh and discover just how little space all of humanity’s writing might take up.
