"It would be hard to imagine a clearer popular account of the topology and geometry of space." -- A. K. Dewdney, Professor of Computer Science, University of Western Ontario, London, Ontario, Canada

"This is a wonderful book, loaded with interesting puzzles and new information." -- Rudy Rucker, author of the Fourth Dimension and Infinity and the Mind

As a high school student, many of the books regarding topology and manifolds are not always easy to follow. Jeffrey Weeks implements several illustrations and a simple yet poetic writing style to effectively portray worldy concepts to readers of all levels (even high scool students). It is obvious that he has a passion about his subject and has definitely inspired me to open my mind to mathematical ideas that had never found me before. I recommend this book to all readers!
