“Oh, what a pleasant booklet! this can be the clearest clarification of relativity available—and the main enjoyable. It’s nice to have it on hand back. even if you’re a scientist, you'll enjoy this book.”—Walter Isaacson, writer of *Einstein: His existence and Universe*

Using “just adequate arithmetic to assist and never to prevent the lay reader,” Lillian R. Lieber presents an intensive rationalization of Albert Einstein’s idea of relativity. Her pleasant kind, together together with her husband’s captivating illustrations, makes for an engaging and available examine essentially the most celebrated principles of all times.

“A transparent and bright exposition of the basic rules and strategies of the speculation of relativity…can be warmly steered particularly to people who can't spend an excessive amount of time at the subject.”—Albert Einstein

“If you recognize high-school math, will not be terrified of equations, and need to determine what Einstein fairly stated, learn Lillian Lieber’s booklet. she is going to lead you thru exact and common relativity, supporting you at each step to appreciate the fundamental equations, together with tensors, with remarkable readability and conciseness. This uniquely fascinating booklet is still as bright as ever or even extra worthwhile, due to the superb new foreward and notes by means of David Derbes and Robert Jantzen.”—Peter Pesic, writer of *Abel’s evidence: An Essay at the assets and which means of Mathematical Unsolvability* and *Sky in a Bottle*

“Does the character of time fascinate you? Does gravity look a mysterious topic? Are you interested by studying simply what it's that Einstein truly did that made him so recognized? Then this glorious booklet is simply the article. I learn the unique 1945 variation whilst i used to be a high-school scholar within the Nineteen Fifties, and it had an incredible impression on me. I are expecting a similar event for you, or even a younger buddy, with this new, up to date edition.”—Paul J. Nahin, writer of *Time Machines*, *Oliver Heaviside*, and *Dr. Euler’s awesome Formula*
