Her pleasant kind, together along with her husband’s fascinating illustrations, makes for an engaging and obtainable examine probably the most celebrated principles of all times.

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

“If you recognize high-school math, should not frightened of equations, and need to determine what Einstein quite acknowledged, learn Lillian Lieber’s booklet. she's going to lead you thru detailed and common relativity, assisting you at each step to appreciate the fundamental equations, together with tensors, with notable readability and conciseness. This uniquely fascinating booklet continues to be as vibrant as ever or even extra necessary, due to the superb new foreward and notes by means of David Derbes and Robert Jantzen.”—Peter Pesic, writer of *Abel’s facts: An Essay at the assets and that means of Mathematical Unsolvability* and *Sky in a Bottle*

“Does the character of time fascinate you? Does gravity look a mysterious topic? Are you curious about studying simply what it really is that Einstein truly did that made him so well-known? Then this excellent publication is simply the article. I learn the unique 1945 variation while i used to be a high-school pupil within the Fifties, and it had a massive influence on me. I are expecting an analogous event for you, or even a younger good friend, with this new, up-to-date edition.”—Paul J. Nahin, writer of *Time Machines*, *Oliver Heaviside*, and *Dr. Euler’s awesome Formula*
