The Meaning of Einstein's Equation
This is a brief introduction to general relativity, designed for both
students and teachers of the subject. While there are many excellent
expositions of general relativity, few adequately explain the geometrical

a simple formulation of this equation in terms of the motion of freely falling
test particles. We also sketch some of its consequences, and explain how the
formulation given here is equivalent to the usual one in terms of tensors.
Finally, we include an annotated bibliography of books, articles and websites
suitable for the student of relativity.Comment: 23 pages LaTeX, 8 encapsulated Postscript figures; unlike the
published version this includes a derivation of the inverse-square force la
