Quantum mechanics is full of surprises. But somehow, the theory is captured almost entirely in a single equation. Today we explore the Schrödinger equation: how it works, what it says about nature, and why it revolutionized physics.

In the years leading up to the Large Hadron Collider turning on, the physics community was buzzing with curiosity and excitement about what they were about to discover. These moments were captured in the documentary Particle Fever, created by the particle physicist David Kaplan. On today's episode, he recounts these historic years from the perspective of both physicist and filmmaker.
