The only numbers in this book are the page numbers. An illustrated tour of the structures and patterns we call "mathematics".

This book is an original, lively, interactive guide to the three main branches of theoretical mathematics – topology, analysis, and algebra – which turn out to be astonishingly understandable. It overturns the conventional approach to mathematics by encouraging everyone to think creatively about shape and dimension, infinity and infinitesimal, symmetries, proofs, and how all these concepts are intertwined.

Readers are offered a free stroll among the inimitable pleasures and unresolved mysteries of this tremendously important field of knowledge.
