This book helps readers learn relativity at the speed of light! 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: master theoretical physics at your own pace; learn the formulas and principles of special and general relativity from hundreds of worked examples; use practical mathematical tools for solving relativity problems; receive layperson's explanations for Schwarzhild spacetimes, black holes, gravitational radiation, and actual current research; perform better in one of the scariest courses of all; and, take a final exam and grade it yourself!Simple enough for beginners but challenging enough for those who already know something about relativity, Relativity Demystified is the best self-teaching tool or brush-up you can find!
