The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.

Richard Feynman, an American theoretical physicist, received his Ph.D. from Princeton University in 1942 and worked at Los Alamos, New Mexico, on the atomic bomb during World War II. From 1945 to 1950, he taught at Cornell University and became professor of theoretical physics at the California Institute of Technology in 1950. Feynman made important contributions to quantum electrodynamics (QED) and electromagnetic interactions, such as interactions among electrons. In Feynman's approach, interactions are considered exchanges of virtual particles. For example, Feynman explained the interaction of two electrons as an exchange of virtual photons. Feynman's theory has proved to be accurate in its predictions. In 1965 the Nobel Prize for physics was awarded to three pioneers in quantum electrodynamics: Feynman, Julian Schwinger, and Sin-Itiro Tomonaga. Feynman was an outspoken critic of NASA for its failure to notice flaws in the design of the Challenger space shuttle, which resulted in its tragic explosion.
