In The Quantum Theory of Fields Nobel Laureate Steven Weinberg com-
bines his exceptional physical insight with his gift for clear exposition to
provide a self-coniained, comprehensive, and up-to-date introduction to
quantum field theory.
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, and emphasi?ing the reasons why
such a theory should describe nature. After a brief historical outline, the
book begins anew with the principles about which we arc most certain,
relativity and quantum mechanics, and the properties of particles that
follow from these principles. Quantum field theory then emerges from this
as a natural consequence.
The classic calculations of quantum electrodynamics arc presented in a
thoroughly modern way, showing the use of path integrals and dimensional
regularization. The account of renormalization theory reflects the changes
in our view of quantum field theory since the advent of effective field
theories.
The book's scope extends beyond quantum electrodynamics to ele-
mentary particle physics and nuclear physics, 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. Problems
are included at the end of each chapter.
A second volume will describe the modern applications of quantum
field theory in today's standard model of elementary particles, and in
some areas of condensed matter physics.
This will be an invaluable reference work for all physicists and mathe-
maticians who use quantum field theory, as well as a textbook appropriate
to graduate courses.
