The first edition of this work appeared in 1930, and its originality won it immediate recognition as a classic of modern physical theory. The fourth edition has been bought out to meet a continued demand. Some improvements have been made, the main one being the complete rewriting of the chapter on quantum electrodymanics, to bring in electron-pair creation. This makes it suitable as an introduction to recent works on quantum field theories.

User Review  - Joecolelife - Goodreads

First, a disclosure: this was my first QM text. That's right. I picked it up as a sophomore in electrical engineering. This could easily have nipped any hope for a career in research. Rather, I was ... Read full review
