This classic physics text attests to the importance of Richard Feynman's graphs and rules of calculation, and it advises physicists to incorporate Feynman's calculations into their problem-solving methods for canonical quantum field theory. Written by a pair of prominent theoretical physicists, it is geared toward advanced undergraduate and graduate physics majors.

Starting with an examination of general formalism, the treatment explores the Klein-Gordon field, second quantization of the Dirac field, quantization of the electromagnetic field, interacting fields, and vacuum expectation values and the scattering matrix. Additional subjects include perturbation theory, dispersion relations, and renormalization. Three appendixes supplement the text.
