Games and Mathematics: Subtle Connections

Description

The appeal of games and puzzles is timeless and universal. In this unique book, David Wells explores the fascinating connections between games and mathematics, proving that mathematics is not just about tedious calculation but imagination, insight and intuition. The first part of the book introduces games, puzzles and mathematical recreations, including knight tours on a chessboard. The second part explains how thinking about playing games can mirror the thinking of a mathematician, using scientific investigation, tactics and strategy, and sharp observation. Finally the author considers game-like features found in a wide range of human behaviours, illuminating the role of mathematics and helping to explain why it exists at all. This thought-provoking book is perfect for anyone with a thirst for mathematics and its hidden beauty; a good high school grounding in mathematics is all the background that is required, and the puzzles and games will suit pupils from 14 years.

David Wells is the author of more than a dozen books on popular mathematics, puzzles and recreations. He has written many articles on mathematics teaching and a secondary mathematics course based on problem-solving. A former British under-21 chess champion, he has also worked as a game inventor and puzzle editor.

'One of the wellsprings out of which the discipline of mathematics has developed is human delight in intellectual play, manifest in the ubiquity of abstract games across millennia and cultures. The author of this fascinating book is expert in both domains, and in the art of clearly explaining significant aspects of mathematics in ways both accessible to non-experts and illuminating to experts. Through a delightfully rich variety of historical and multicultural examples, he unveils the intimate relationship between abstract games and mathematics as the study of structures, and, in so doing, illuminates much more about mathematical behaviour and cognition. At a time when too much of mathematics education in school seems designed to squeeze out every last drop of playfulness, we are reminded that mathematics can, and should, be an intellectual playground.' Brian Greer, Portland State University 'This is a very approachable yet erudite book. Wells' game is to turn Plato's theory of forms on its head: instead of starting with physical examples and imagining their ideal forms, we should take our cue from the abstract laws and intuitions of games. Chess pieces are defined by their powers rather than their physical forms, and so are many situations in mathematics ... The book illustrates this thesis with fascinating context: from Ulam's 'lucky' numbers ... to the symmetry of the theorem discovered by Emperor Napoleon and the mathematics which arises in Go, Hex and chess ... Games and Mathematics makes an important advance in communicating the nature of mathematics. It contains a profound message for philosophers of mathematics, but all mathematically-inclined readers will find [it] as compelling as Wells' excellent 'Curious and Interesting' books.' Paul Brown, author of Proof: Interesting Activities in Conjecture and Mathematical Proof 'This is no ordinary compilation of recreational problems in mathematics ... the text reads well and is something of a page-turner ... this is not a mere compilation of problems, but a guided tour, and one would hope that it would reach a wider audience, so the authors' expressed intention, of showing that mathematics is not merely computation, but actually foremost an imaginative play, should become effective ... All in all this could be a delightful volume in every aspect and I find myself recommending the work ... with warmth and enthusiasm and with no qualms.' Ulf Persson, Chalmers University of Technology, Gothenburg 'Complete with a consistent argument and a wealth of supportive references, this is a fun work for both game players and mathematicians to explore. Highly recommended.' J. Johnson, Choice
