The Quantum Theory of Fields v1

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.
