Provides the means to master gauge field theory prior to the advanced study of quantum mechanics. This book begins with the basic concepts on which gauge field theory is built. It introduces gauge-invariant Lagrangians and describes the spectra of linear perturbations, including perturbations above nontrivial ground states.
