Special Relativity and Motions Faster than Light

Moses Fayngold

This is a book about Special Relativity. The potential reader may ask why yet another book needs to be written on this subject when so many have already covered this ground, including some classical early popularizations. There are four answers to this question.

First, this book is intended to supplement the ordinary physics texts on Special Rela-tivity. The author’s goal was to write a book that would satisfy the demands of differ-ent categories of reader, such as college students on the one hand and college profes-sors teaching physics on the other. To this end, many sections are written on two le-vels. The lower level uses an intuitive approach that will help undergraduates to grasp qualitatively, fundamental aspects of relativity theory. The higher level contains a rigorous analytical treatment of the same problems, providing graduate students and professional physicists with a good deal of novel material analyzed in depth. The readers may benefit from this approach.
