## Mathematical Puzzle TalesMartin Gardner is widely known for his writing on recreational mathematics, not least for the myriad problems he has devised over some 25 years for Scientific American. In this book are collected 36 of his best brainteasers. These are not simply cunning puzzles, but serve to illustrate the art of the mathematician as problem solver, and their solution draws on ideas from topology, probability, number theory, logic and beyond. Fully worked answers are given, which in turn lead to additional problems for the reader. For anybody who likes to solve mathematical problems this book will be both entertaining and a challenge. |
