"For if each Star is little more a mathematical Point,
located upon the Hemisphere of Heaven by Right Ascension and Declination,
then all the Stars, taken together, tho' innumerable,
must like any other set of points,
in turn represent some single gigantick Equation,
to the mind of God as straightforward as, say, the Equation of a Sphere,---
to us unreadable, incalculable.
A lonely, uncompensated, perhaps even impossible Task,---
yet some of us must ever be seeking, I suppose."
-- Thomas Pynchon, Mason & Dixon

About the Book

In 1996 I taught a one-semester graduate course graduate course in general relativity at MIT. Along the way I typed up a detailed set of lecture notes. The book Spacetime and Geometry is a significantly revised and expanded version of these notes; about half of the finished book is completely new. The lecture notes will continue to be available for free online.

The philosophy of the book is to provide an accessible, useful, and pedagogical introduction to general relativity. In particular, no effort has been made to write a comprehensive reference book. More on the approach taken can be found in the preface.

You can order the book online from Amazon.com or from Addison Wesley.
