Covers the advances in the field while providing a conceptual foundation for students to build on quantum field theory available. This title includes exercises, explanations, and examples, as well as detailed appendices, solutions to selected exercises, and suggestions for further reading.

"A beautiful exposition of the way modern field theorists think about quantum field theory, packed with insights and physical intuition. Zee's book should be required reading for every serious student of the subject."--Nima Arkani-Hamed, Institute for Advanced Study

"[This] is an excellent invitation to the wide area of modern quantum field theory, and even provides the mature field theoretician with interesting insights and connections. To the curious student, it is a near-perfect companion to spice up the world of quantum field theory, especially particle physics, beyond the standard presentations. . . . It is definitely highly recommendable to anyone who wants to have a book with a non-standard view on quantum field theory, or who just wants to have an entertaining and insightful reprise of the topic."---Axel Maas, Mathematical Reviews Clippings
