The Geometry of Special Relativity (2nd Edition)

This short book treats the geometry of hyperbolas as the key to understanding
special relativity. This approach can be summarized succinctly as the
replacement of the ubiquitous gamma symbol of most standard treatments with
the appropriate hyperbolic trigonometric functions. In most cases, this not
only simplifies the appearance of the formulas, but emphasizes their geometric
content in such a way as to make them almost obvious. Furthermore, many
important relations, including but not limited to the famous relativistic
addition formula for velocities, follow directly from the appropriate
trigonometric addition formulas.

The core of the book remains unchanged from the first edition. In response to
reader feedback, the treatment of Minkowski space and spacetime diagrams has
been expanded slightly, with minor changes in notation. In addition, several
new topics have been added, numerous small typos have been corrected, and more
homework problems have been added. The new material includes a geometric
derivation of Lorentz transformations, a discussion of three-dimensional
spacetime diagrams, and a brief geometric description of ``area'' and how it
can be used to measure time and distance.
