Finding Moonshine by Marcus du Sautoy

A Mathematician's Journey Through Symmetry

A personal, accessible journey through the idea of symmetry that traces how patterns in art, nature and numbers led to one of the most surprising discoveries in modern mathematics: mysterious links between a giant algebraic object (the so‑called “Monster” symmetry) and certain modular functions, a phenomenon dubbed “moonshine.” Blending history, biography and clear explanations of group theory, modular forms and the personalities behind the work, the book follows the narrator’s conversations with mathematicians and visits to key places to show how abstract algebraic structures unexpectedly connect to analysis and even ideas in physics, revealing both the beauty of symmetry and the human stories that drive mathematical discovery.
