A Mathematical Gallery

Educator and artist Lisl Gaal presents a compendium of color illustrations to elucidate fundamental concepts in mathematics. Apparently compiled in the late 1970s (the Seven Circles Theorem from 1974 by Evelyn, Money-Coutts, and Tyrrell is described as “proved recently”), this collection should appeal to the many fans of the well-known “Proofs Without Words” that have appeared in the MAA's Mathematics Magazine since the same era: 1975.

The art is colorful and whimsical. Merry-go-rounds, fruit stands, dogs, and more are used to clarify the complex plane, Markov chains, generalized approaches to volume, and concepts up to basic calculus. Each chapter is an overview illustration supported by a few pages of text and additional figures. The material is ready for the reader seeking introduction to these ideas without rigor, or as classroom capsules to enliven presentation to high school and first-year college audiences.
