Theory of Fundamental Processes

Feynman treats the concept of amplitude in special detail, discusses relativity, and then moves on to quantum electrodynamics, which takes up most of this volume..

In these classic lectures, Richard Feynman first considers the basic ideas of quantum mechanics, treating the concept of amplitude in special detail and emphasizing that other things, such as the combination laws of angular momenta, are largely consequences of this concept.

Feynman also discusses relativity and the idea of anti-particles, finally returning to a discussion of quantum electrodynamics, which takes up most of this volume.
