Ebook: Hexaflexagons and other mathematical diversions: the first Scientific American book of puzzles & games

These clearly and cleverly presented mathematical recreations of paradoxes and paperfolding, Moebius variations and mnemonics both ancient and modern delight and perplex while demonstating principles of logic, probability, geometry, and other mathematical fields.

"A classic."--Andrew Rothery, Times Education Supplement

"Martin Gardner has turned a trick as neat as any in the book itself. He has selected a group of diversions which are not only entertaining but mathematically meaningful as well. The result is a work which is rewarding on almost every level of mathematical achievement."--Miriam Hecht, Iscripta Mathematica
