Скачать или смотреть Richard Feynman on Why Time Can't Go Backwards

You think time moves forward because that's just how things work. But physics shows something far stranger - time's direction isn't built into the laws of nature. Richard Feynman walks us through the mystery of entropy and why the universe seems to remember its past but not its future.
Every physical law we know works perfectly in reverse. Drop a glass and it shatters - but the equations say those fragments could spontaneously reassemble into a whole glass. Mix cream into coffee and watch them separate back into distinct layers. Physics allows it all. So why doesn't it happen?
This is the story of the second law of thermodynamics - the only law in physics that gives time a direction. We can calculate exactly how entropy increases, but we cannot explain why the universe began in such an improbably ordered state that allows this increase to happen.
The mathematics is precise. The predictions are perfect. But the explanation reveals a cosmos far stranger than we imagined - one where time's arrow points toward chaos not because it must, but because it began impossibly organized for reasons we cannot fathom.
Watch till the end. The implications might change how you see every moment of your existence.
