The Magic Theorem: a Greatly-Expanded, Much-Abridged Edition of The Symmetries of Things presents a wonder- fully unique re-imagining of the classic book, The Symmetries of Things. Begun as a standard second edition by the original author team, it changed in scope following the passing of John Conway. This version of the book fulfills the original vision for the project: an elementary introduction to the orbifold signature notation and the theory behind it.

The Magic Theorem features all the material contained in Part I of The Symmetries of Things, now redesigned and even more lavishly illustrated, along with new and engaging material suitable for a novice audience. This new book includes hands-on symmetry activities for the home or classroom and an online repository of teaching materials avaialble at themagictheorem.com

Biographical note

John H. Conway was the John von Neumann Chair of Mathematics at Princeton University. He obtained his BA and his PhD from the University of Cambridge (England). He was a prolific mathematician active in the theory of finite groups, knot theory, number theory, combinatorial game theory, and coding theory. He also contributed to many branches of recreational mathematics, notably the invention of the Game of Life.

Heidi Burgiel holds a Ph.D. in Geometry from the University of Washington and a Master’s degree from the Harvard Graduate School of Education. Her professional activities range from mathematical fiber arts through computer systems administration. Over the past 30 years she has worked at the University of Washington, the University of Minnesota, the University of Illinois at Chicago, the Boston Museum of Science, Boston University, Bridgewater State University, the Massachusetts Institute of Technology, Harvard University, the University of Massachusetts at Lowell, and Lasell University.

Chaim Goodman-Strauss is Outreach Mathematician at the National Museum of Mathematics (MoMath). Born and raised in Austin, Tex., he earned his Ph.D. in Knot Theory at UT Austin in 1994 and served through 2022 on the mathematics faculty at the University of Arkansas. He has held visiting positions at the Geometry Center at the University of Minnesota, Princeton University, and the Universidad Nacional Autónoma de México.
