A working knowledge of Einstein's theory of general relativity is an
essential tool for every physicist today. This self-contained book is an
introductory text on the subject aimed at first-year graduate students,
or advanced undergraduates, in physics that assumes only a basic
understanding of classical Lagrangian mechanics. The mechanics problem
of a point mass constrained to move without friction on a
two-dimensional surface of arbitrary shape serves as a paradigm for the
development of the mathematics and physics of general relativity. After
reviewing special relativity, the basic principles of general relativity
are presented, and the most important applications are discussed. The
final special topics section guides the reader through a few important
areas of current research.This book will allow the reader to approach
the more advanced texts and monographs, as well as the continual influx
of fascinating new experimental results, with a deeper understanding and
sense of appreciation.
