***********************************************************************************

Now anyone can grasp Einstein's great theory of relativity -- without formal training, unlimited time, or a genius IQ. In Relativity Demystified, theoretical physicists (and student-savvy authors) David McMahon and Paul Ansing provide an effective, illuminating, and entertaining way to learn the essentials and formulas of Einstein's theories.
With Relativity Demystified, you master the subject one step at a time—at your own speed. This unique self-teaching guide offers problems at the end of each chapter and part to pinpoint weaknesses, and a 100-question final exam to reinforce the entire book.
This fast and entertaining self-teaching course makes it much easier to:
