The Einstein Theory of Relativity: A Trip to the Fourth Dimension

“Oh, what a delightful book! This is the clearest explanation of relativity available—and the most fun. It’s great to have it available again. Whether or not you’re a scientist, you will relish this book.”—Walter Isaacson, author of Einstein: His Life and Universe

Using “just enough mathematics to help and not to hinder the lay reader,” Lillian R. Lieber provides a thorough explanation of Albert Einstein’s theory of relativity. Her delightful style, in combination with her husband’s charming illustrations, makes for an interesting and accessible read about one of the most celebrated ideas of all times.

Lillian R. Lieber was a professor and head of the Department of Mathematics at Long Island University. She wrote a series of lighthearted (and well-respected) math books, many of them illustrated by her husband, Hugh Gray Lieber.
