"What is the Quantum Theory of Fields?" is a 1997 review of QFT by the author of the 3-volume, 1,600 page book entitled "Quantum Theory of Fields" (QFT). (The latter is an authoritative `complete' mathematical and physical treatment of the Quantum Theory of Fields including Quantum Supergravity Theory in vol. 3. The first volume introduces the foundations of quantum field theory, the second volume examines modern applications, and the third volume presents supersymmetry. From contents : Volume I: 1. Historical introduction, 2. Relativistic quantum mechanics, 3. Scattering theory, 4. The cluster decomposition principle, 5. Quantum fields and antiparticles, 6. The Feynman rules, 7. The canonical formalism, 8. Massless particles: electrodynamics.) In this review, Nobel Laureate Steven Weinberg combines his exceptional physical insight with his gift for clear exposition to provide a self-contained, comprehensive, and up-to-date introduction to quantum field theory: "In fact, it was quite soon after the Born--Heisenberg--Jordan paper of 1926 that the idea came along that in fact one could use quantum field theory for everything, not just for electromagnetism. This was the work of many theorists during the period 1928--1934, including Jordan, Wigner, Heisenberg, Pauli, Weisskopf, Furry, and Oppenheimer." http://xxx.lanl.gov/pdf/hep-th/9702027v1
