Quantum Field Theory of Point Particles and Strings (Written by Brian Hatfield)

The purpose of this book is to introduce string theory without assuming any background in quantum field theory. Part 1 of the book follows the development of quantum field theory for point particles, while Part II introduces strings. All of the tools needed to quantize strings are developed from point particles. The emphasis of this book is calculational and most computations are presented in step-by-step detail. This book is unique in that it develops all three representations of quantum field theory (Operator, Schrodigner and path integral) for point particles and strings. In many cases identical results are worked out to emphasize the representation-independent nature of quantum field theory.

Feynman Lectures on Gravitation (Edited by Brian Hatfield)

The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics thet Richard Feynman taught at Caltech during the 1962-1963 acedemic year. Characteristically, Feynman took the non-traditional, non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. This approach also demonstrates the intimate and fundamental conneciton between gauge invariance and the principle of equivalence. The late Dr. Feynman shared the 1965 Nobel prize in physics for his work on Quantum Electrodynamics (QED).
