E-Book Overview
The author of The Joy of Mathematics explores the mathematics of nature, literature and art. This fascinating look at the surprising ways mathematics influences the everyday world takes an abstract universe and anchors it to the "real" worlds of science, history and the arts in an intriguing way. Photos and line drawings.

This book is a collection of ideas - ideas with an underlying mathematical theme. It is not a textbook. Do not expect to become proficient in a topic or find an idea exhausted. The Magic of Mathematics delves into the world of ideas, explores the spell mathematics casts on our lives, and helps you discover mathematics where you least expect it. Many think of mathematics as a rigid fixed curriculum. Nothing could be further from the truth. The human mind continually creates mathematical ideas and fascinating new worlds independent of our world - and presto these ideas connect to our world almost as if a magic wand had been waved. The way in which objects from one dimension can disappear into another, a new point can always be found between any two points, numbers operate, equations are solved, graphs produce pictures, infinity solves problems, formulas are generated - all seem to possess a magical quality. Mathematical ideas are figments of the imagination. Its ideas exist in alien worlds and its objects are produced by sheer logic and creativity. A perfect square or circle exists in a mathematical world, while our world has only representations of things mathematical. The topics and concepts which are mentioned in each chapter are by no means confined to that section. On the contrary, examples can easily cross over the arbitrary boundaries of chapters. Even if it were possible, it would be undesirable to restrict a mathematical idea to a specific area. Each topic is essentially self-contained, and can be enjoyed independently. I hope this book will be a stepping stone into mathematical worlds. -t rw \"' Print Gallery
