Einstein's general theory of relativity requires a curved space for the
description of the physical world. If one wishes to go beyond
superficial discussions of the physical relations involved, one needs to
set up precise equations for handling curved space. The well-established
mathematical technique that accomplishes this is clearly described in
this classic book by Nobel Laureate P.A.M. Dirac. Based on a series of
lectures given by Dirac at Florida State University, and intended for
the advanced undergraduate, General Theory of Relativity comprises
thirty-five compact chapters that take the reader point-by-point through
the necessary steps for understanding general relativity.
