Spacetime Physics Spacetime Physics
by Edwin F. Taylor and John Archibald Wheeler

312 pages
Level: Introductory college

Special Relativity as a form of Geometry with a brief introduction to General Relativity also

"Spacetime Physics" is the perfect example of what a scientific text book should be: clear, interesting, bursting with idea and loaded with solved exercises.

In a few pages Taylor and Wheeler have managed to explain the basics of the Special Theory of relativity, as a GEOMETRIC theory. The authors accomplish this by an ingenious comparison of three dimensional Euclidean geometry with four dimensional Lorentz geometry. The illustrations are helpful and the text friendly.

What makes "Spacetime Physics" so helpful is its use of exercises. Most relativity texts include exercises accompanied by a warning that unless the student actually solves them, he or she will not truly understand the material. This is fine for the very talented student who is able to solve all the exercises or at least has access to a teacher for guidance. But what about the reader who is using the book for self study? Not only does "Spacetime Physics" have a good number of exercises, but they are ALL solved in a enough detail, that even a reader who is left on his own will be able to get through and learn from them.

The only prerequisites are a basic knowledge of algebra and geometry (especially Pythogrean's Theorem).

The first chapter deal with space and time, while the second chapter expands on this to add energy and momentum. The third and final chapter, introduces General Relativity but without any accompanying mathematics.

While the "Spacetime Physics" is aimed at the college undergraduate, a bright high school student will also get a great deal out of it.
