Episode notes
The 'Fox and the Grapes' of Quantum Physics
- Quantum mechanics, though successful, has a problem: physicists don't know what's really happening.
- Sean Carroll argues this stems from prioritizing predictions over deep understanding, like the fox and the grapes.
The Unstable Atom
- The classical model of the atom, with electrons orbiting the nucleus, predicts matter should be unstable.
- This contradicts reality, showing a need for a new theory.
Wave-Particle Duality
- Electrons behave like waves when unobserved, explaining atomic stability.
- However, observations like cloud chamber experiments show them as particles, creating a contradiction.
