The Symmetries of Things was — is — a magical book; it even has a Magic Theorem! This extended as well as abridged new version (a magical combination in itself) is a welcome (and more affordable!) introduction into the joys of seeing, understanding and constructing symmetries.

The Magic Theorem is a joyful exploration of symmetry and the elegant geometry of orbifolds. Conway, Burgiel, and Goodman-Strauss have created something rare: a book that distills deep mathematics into a playful, visually stunning experience. Whether you’re encountering these ideas for the first time or rediscovering them with fresh eyes, this is a guided tour filled with clarity, wonder, and charm.

Leaving behind the graduate-level math, Burgiel and Goodman-Strauss have extracted the simplest, most widely appealing part of their earlier book The Symmetry of Things (co-authored with the late John Conway) and expanded it out to a more accessible exposition for a broader audience. With clear explanations and a warm, friendly tone, the text sounds more like the way the authors might explain their ideas to some friends over a beer than what you’d find in a typical math book. And of course the illustrations are every bit as gorgeous as in the authors’ earlier book. More demanding on the reader’s time and energy than a pure popularization, but far less demanding than a typical math book, The Magic Theorem seems ideal for mathematically inclined non-specialists looking for a deeper understanding of symmetry.

Can you handle looking straight into the most fundamental core of the beauty of existence? If you are ready, then this book is where to start.

Have you ever admired the wallpaper in your aunt’s bathroom? Read this book, and you will learn how to identify for her which of the 17 possible wallpaper patterns she displays. Richly illustrated with objects from everyday life, The Symmetries of Things leads you on a journey from everyday patterns seen in architecture and on the soccer pitch to the esoteric world of hyperbolic surfaces and orbifolds. Ample exercises allow one to practice the craft of wallpaper, frieze and game ball pattern identification until it becomes second nature. Not sure you will impress your aunt with your dinner banter, but your D&D friends will be awed when you can categorize the polyhedral dice you are playing with. And if you are not careful, you may develop a desire to learn about higher dimensional patterns underlying crystals, knots and more!
