A clear explanation of the mathematics that underlies Rubik's Cube, and how the cube can be used to grasp the fundamentals of group theory.In thirty years, Rubik's cube, invented by Erno Rubik, has established itself as a neverending source of delight, frustration and intellectual stimulation to children and adults alike. There is a large literature on the subject, but one of the few books to have established themselves as offering a serious contribution to the subject is Alexander H. Frey's and David Singmaster's Handbook of Cubik Math, first published in 1982.Frey and Singmaster were the first to offer an elegant mathematical solution to the cube, doing it in a form that enables readers to understand the processes that have been undertaken. As a result the book has proved readily accessible to generations of high-school maths students and more advanced college students of algebra.The solution is intuitive, and does not require memorisation of formulae. The authors demonstrate how movements of the cube exemplify the fascinating but abstract field of mathematics known as group theory. Using the cube as a model they make comprehensible and concrete the hard-to-understand ideas of group theory. Their hypothesis that the maximum number of moves required for 'God's Algorithm' was in the low twenties was proved correct in 2008 by Tomas Rokicki, who showed that it was twenty-two.In addition to showing how to solve Rubik's cube, the authors explain the theory involved, and its application to similar puzzles. They also show how the cube provides a physical example for many mathematical concepts where such examples are scarce, and the book therefore provides a useful teaching aid.

Just in time to satisfy the kids of all ages who received Rubik's Cubes as holiday gifts, here is the book to ensure that the gift won?t go unused (or unsolved). Puzzle Masters Jerry Slocum, David Singmaster, Dieter Gebhardt, Wei-Hwa Huang, and Geert Hellings, share their expertise on the greatest puzzle ever created. Not only does The Cube provide dozens of strategies for competitive cubing?including speedcubing?it also shows you how to solve every kind of cube that exists: the 'Mini Cube' 2x2x2; the 'Classic' 3x3x3; the 'Rubik's Revenge' 4x4x4; the 'Professor's Cube' 5x5x5; and the largest cubes available, the 'V-Cube 6' 6x6x6 and the 'V-Cube 7' 7x7x7. The book even includes modular instructions for cubes of any potential size! All solutions are fully illustrated with all-new, easy-to-follow instructions created specially for this book. This unique book also includes a fascinating history of the Rubik's Cube?from its invention in 1974 by Ern? Rubik to the '80s craze to its resurgence today, including dozens of rare photographs of vintage cubes, ephemera, and more! Packed with color photos from Jerry Slocum's extensive and unique collection of mechanical puzzles, The Cube is a must-have companion to the ultimate brainteaser.

David Singmaster believes in the presentation and teaching of mathematics as recreation. When the Rubik's Cube took off in 1978, based on thinly disguised mathematics, he became seriously interested in mathematical puzzles which would provide mental stimulation for students and professional mathematicians. He has not only published the standard mathematical solution for the Rubik's cube still in use today, but he has also become the de facto scribe and noted chronicler of the recreational mathematics puzzles themselves.Dr Singmaster is also an ongoing lecturer of recreational mathematics around the globe, a noted mechanical puzzle collector, owner of thousands of books related to recreational mathematical puzzles and the "go to" source for the history of individual mathematical puzzles.This set of two books provides readers with an adventure into previously unknown origins of ancient puzzles, which could be traced back to their Medieval, Chinese, Arabic and Indian sources. The puzzles are fully described, many with illustrations, adding interest to their history and relevance to contemporary mathematical concepts. These are musings of a respected historian of recreational mathematics.

"The collection contains many delightful and enjoyable problems that are either original or taken from old books, which are no longer easily accessible. I especially like the detailed solutions, which make it clear that the author has carefully re-examined all the old problems and often discovered that the previously published solutions were incomplete. Some problems are best solved with the help of a computer, and can serve as original exercises in computer programming. The book provides an enjoyable read, and should not be missing in the library of any metagrobologist."zbMATHDefinition of metagrobolize: puzzle, mystify; puzzle out. Hence, metagrobology is the study of puzzles and metagrobologist an expert in such study. David Singmaster is possibly the world's best known metagrobologist. He gained prominence in the 1980s with a booklet on how to solve the Rubik's Cube.This book is a collection of over 200 problems that David Singmaster has composed since 1987. Some of the math problems have appeared in his various puzzle columns for BBC Radio and TV, Canadian Broadcasting, Focus (the UK popular science magazine), Games and Puzzles, the Los Angeles Times, Micromath, the Puzzle a Day memo pad and the Weekend Telegraph. While some of these are already classics, many of the puzzles have not been published elsewhere previously.Puzzle enthusiasts of all ages will find here arithmetic problems, properties of digits; monetary problems; alpha-metics; Diophantine problems; magic figures; sequence problems; logical problems; geometric problems; physics problems; combinatorial problems; geographic problems; calendar problems; clock problems; dissection problems and verbal problems.Can you solve it? Are you smarter than a metagrobologist? Check out Alex Bellos's Monday Puzzle on The Guardian as he features two sequence puzzles from the book.
