"A delightful book."— New York Times "I have studied with pleasure [this] new book…Beautiful examples…Illuminating. I am convinced that [Lieber's] original enterprise will get the recognition it so richly deserves."—Albert Einstein "The Liebers have written an ingenious, entertaining, and illuminating book."— Saturday Review of Literature "The book should be 'required reading' especially for non-mathematicians." —E.T. Bell, author of The Development of Mathematics First published in 1942, this whimsical exploration of how to think in a mathematical mood continues to delight math-lovers of all ages. Do you know that two times two is not always four; that the sum of the angles in a triangle does not always equal 180°; that sometimes it is possible to draw two parallel lines through the same point? In The Education of T. C. MITS , Lillian Lieber opens the door to the wonder of mathematical thinking and its application to everyday life. Lieber uses simple language and fanciful illustrations drawn by her husband, Hugh, to present fundamental mathematical concepts with a deft touch. The new foreword by Harvard University mathematics professor Barry Mazur is a tribute to the Liebers' influence on generations of mathematicians.

"The interpolations tying mathematics into human life and thought are brilliantly clear."— Booklist "Her presentation…is conversational and humorous, and should help to simplify some complex concepts."— Kirkus Infinity. It sounds simple…but is it? This elegant, accessible, and playful book artfully illuminates one of the most intriguing ideas in mathematics. Lillian Lieber presents an entertaining, yet thorough, explanation of the concept and cleverly connects mathematical reasoning to larger issues in society. Infinity includes a new foreword by Harvard professor Barry Mazur. "Another excellent book for the lay reader of mathematics…In explaining [infinity], the author introduces the reader to a good many other mathematical terms and concepts that seem unintelligible in a formal text but are much less formidable when presented in the author's individual and very readable style."— Library Journal "Mrs. Lieber, in this text illustrated by her husband, Hugh Gray Lieber, has tackled the formidable task of explaining infinity in simple terms, in short line, short sentence technique popularized by her in The Education of T.C. MITS ."— Chicago Sunday Tribune
