The Quantum Theory of Fields: Volume 1, Foundations

Available for the first time in paperback, The Quantum Theory of Fields is a self-contained, comprehensive, and up-to-date introduction to quantum field theory from Nobel Laureate Steven Weinberg.Volume I introduces the foundations of quantum field theory.The development is fresh and logical throughout, with each step carefully motivated by what has gone before.After a brief historical outline, the book begins with the principles of relativity and quantum mechanics, and the properties of particles that follow.Quantum field theory emerges from this as a natural consequence.The classic calculations of quantum electrodynamics are presented in a thoroughly modern way, showing the use of path integrals and dimensional regularization.It contains much original material, and is peppered with examples and insights drawn from the author's experience as a leader of elementary particle research.Exercises are included at the end of each chapter.
