QED - The Most Precise Theory Ever Created

This video is inspired by Richard Feynman's development of Quantum Electrodynamics (QED) and presented from his perspective. Twelve decimal places. That's not approximately correct. That's not close enough. That's nature telling you: yes, you got it right. It's 1946. I'm at Cornell. Depressed. My wife just died. The war just ended. I worked on the atomic bomb. And now quantum physics is broken. The equations give infinite answers. Nonsense. Garbage. Physicists are giving up. Some think quantum field theory is fundamentally wrong. That we need new physics. New principles. That the infinities are telling us something is missing. But I can't give up. The theory is too beautiful. Too elegant. It has to be right. We're just not doing it correctly. So I start drawing pictures. Little diagrams. Lines for electrons. Wiggly lines for photons. Points where they meet. Simple visual representations of what's happening. And something amazing happens. The calculations become manageable. The infinities become controllable. We develop renormalization. We make predictions. And those predictions match experiment. Not approximately. Exactly. To twelve decimal places. In this video: → Why quantum physics was broken in the 1940s → The Shelter Island Conference and Willis Lamb's discovery → How Feynman invented his diagrams and renormalization → The Pocono Conference showdown with Niels Bohr → How QED achieved 12 decimal place precision → Why this is the most accurate theory in all of science → How every computer chip depends on QED The magnetic moment of the electron. Predicted to 1.001159652181. Measured to 1.001159652180. That's like measuring LA to NY and getting it right within a hair's width. That's not luck. That's understanding.
