## Resource

A detailed look into the physics and mathematics of quantum electrodynamics, the theory of how light and matter interact. We discuss the generalisation of the Schrodinger equation to the Klein-Gordon and Dirac equations, and howw these describe the propogation of light and fermions respectively. We then consider the process of computing transition probabilities between quantum states, including the S matrix and perturbation theory, and Wick's theorem. Recommended pre-listening is Episode 85: Introduction to Quantum Field Theory.
