The Second Scientific American Book of Mathematical Puzzles and Diversions

Martin Gardner9780226282534, 0-226-28253-8

This delightful collection from the magician of math introduces readers to magic squares, the Generalized Ham Sandwich Theorem, origami, digital roots, an update of the Induction Game of Eleusis, Dudeney puzzles, the maze at Hampton Court palace, and many more mathematical puzzles and principles. “Gardner is often the clown prince of science. . . . His Mathematical Games column in Scientific American is one of the few bridges over C. P. Snow’s famous ‘gulf of mutual incomprehension’ that lies between the technical and literary cultures.”— Time
