Gardner-Mathematics Magic and Mystery

Why do card tricks work? How can magicians do astonishing feats of mathematics mentally? Why do stage mind-reading tricks work? As a rule we simply accept these tricks and magic without recognizing that they are really demonstrations of strict laws based on probability sets number theory topology and other branches of mathematics.This is the first book-length study of this fascinating branch of recreational mathematics. Written by one of the foremost experts on mathematical magic it employs considerable historical data to summarize all previous work in this field. It is also a creative examination of laws and their exemplification with scores of new tricks insights and demonstrations. Dozens of topological tricks are explained and dozens of manipulation tricks are aligned with mathematical law.Nontechnical detailed and clear this volume contains 115 sections discussing tricks with cards dice coins etc.; topological tricks with handkerchiefs cards etc.; geometrical vanishing effects; demonstrations with pure numbers; and dozens of other topics. You will learn how a Moebius strip works and how a Curry square can prove that the whole is not equal to the sum of its parts.No skill at sleight of hand is needed to perform the more than 500 tricks described because mathematics guarantees their success. Detailed examination of laws and their application permits you to create your own problems and effects.
