Noted mathematician T. H. O'Beirne leads readers through a delightful maze of problems and solutions that are as artfully formed as any great poem or melody. Most require little mathematical knowledge, just careful logic and a playful imagination. Each chapter presents a series of thematically related brainteasers: difficult journeys featuring unlikely passengers and inadequate transport; geometric paradoxes; pouring liquid puzzles; cube and color arrangement puzzles; and calendar paradoxes, including the mathematics and astronomy involved in the varying date of Easter. O'Beirne's emphasis on explanations prepares readers for puzzles of even greater complexity, and solutions are discussed along with the problems. In addition, an illuminating postscript contains extensive historical background and other information to enrich the understanding and appreciation of these stimulating games for the mind.
