Do any content differences exist between these editions of 'The Theory of Photons and Electrons' by J. M. Jauch and F. Rohrlich?
I have the first edition and the third edition.
According to my research, there are some content differences between the first and third editions. The third edition includes new discussions on quantum electrodynamics and field quantization, while the first edition does not cover these topics.
