I am not a physicist but I am into quantum mechanics and statistical mechanics.
In my department, the quantum mechanics we do include only Schroedinger's equation and problems, some approximation methods like perturbation theory. I would like to learn more about Dirac, Feynman diagrams, quantum electrodynamics and chromodynamics -quantum field theory in general-.
I am searching for a book that is easy to follow and has the facts in chronological order in order to have a complete understanding about the problems that appeared in each theory that arose in that times. Without cutting off the mathematical background of all those.
Maybe all these are not in one book. In the books I have found, different theories appear here and there without any linkage between them.
