Origami, Eleusis, and the Soma Cube

Martin Gardner continues to delight. He introduces readers to the Generalized Ham Sandwich Theorem, origami, digital roots, magic squares, the mathematics of cooling coffee, the induction game of Eleusis, Dudeney puzzles, the maze at Hampton Court Palace, and many more mathematical puzzles and principles. Origami, Eleusis, and the Soma Cube is the second volume in Martin Gardner's New Mathematical Library, based on his enormously popular Scientific American columns. Now the author, in consultation with experts, has added updates to all the chapters, including new game variations, mathematical proofs, and other developments and discoveries, to challenge and fascinate a new generation of readers.

'Martin Gardner's fifteen volumes about Mathematical Games are The Canon - timeless classics that are always worth reading and rereading.' Don Knuth

'Hexaflexagons, Probability Paradoxes, and the Tower of Hanoi and Origami, Eleusis, and the Soma Cube provide a taste of Gardner's prowess at devising quirky and fascinating mathematical conundrums. An excellent example is the 'generalised ham-sandwich theorem', which, among other things, explains how a doughnut can be sliced into 13 pieces by three simultaneous plane cuts.' Physics World

'I recommend you approach this book on a Sunday afternoon, with paper and pen, a few biscuits for brain-power and a good hour to spare for puzzling. It is worth it.' Charlotte Mulcare, Plus Magazine

'One of Gardner's real strengths as a writer of popular mathematics is his ability to choose topics that will appeal to the general public while also having some real mathematical content. ... Like the first volume, this one is in the 'must have' category.' MAA Reviews

'... presents plenty of well-known and some less well-known mathematical problems. ... The presentation of problems is completed with many illustrative pictures and photos in every chapter. It is possible to find traditional solutions of every problem and also some newer views, explanations and proofs of solved problems.' EMS Newsletter

'The ten chapters in this volume are a wonderful part of Martin Gardener's work, each updated with selections from the enormous correspondence he enjoyed with his readers. This collection of Gardener's writing should be a cornerstone of a personal library for mathematicians, teachers and students everywhere.' Mathematical Reviews

For 25 of his 90 years, Martin Gardner wrote 'Mathematical Games and Recreations', a monthly column for Scientific American magazine. These columns have inspired hundreds of thousands of readers to delve more deeply into the large world of mathematics. He has also made significant contributions to magic, philosophy, debunking pseudoscience, and children's literature. He has produced more than 60 books, including many best sellers, most of which are still in print. His Annotated Alice has sold more than a million copies. He continues to write a regular column for the Skeptical Inquirer magazine.
