Once You Learn About This Theorem, You Can't See The World The Same Way

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/1Nm0Qc8... In the summer of 1918, a 23-page paper was read aloud to a Royal Academy in Germany by a man who did not write it, because the woman who wrote it was not allowed in the room. Albert Einstein called her a genius. Her proof answered a question that had stumped physics for two centuries: why can energy never be created or destroyed? Once you understand what Emmy Noether actually found hiding inside every spinning skater and every orbiting planet, can you ever look at a doorway holding its shape the same way again? Over these 2 hours and 19 minutes, the story moves from a locked lecture hall in Göttingen, where Emmy Noether was forbidden to teach under her own name, through two centuries of energy conservation, from Émilie du Châtelet's falling brass balls to James Joule's honeymoon waterfalls, and into the principle of least action that Richard Feynman said he never recovered from learning. It follows the theorem outward into a figure skater's spin, a pulsar turning 716 times a second, Wolfgang Pauli's desperate bet on an invisible particle, and the night Chien-Shiung Wu discovered the universe is not ambidextrous. By the end, you will understand why an ordinary current in a wire, or a cup of coffee cooling on your nightstand, never looks quite the same again. Get cozy and let this slow walk through Emmy Noether's theorem and the hidden symmetry behind every law of physics keep you company tonight.
