“A profusely illustrated, bemusingly unorthodox introduction to math.”—BooklistA book for the eternally curious, Coincidences fuses a professor’s understanding of the hidden mathematical skeleton of the universe with the sensibility of a stand-up comedian, making life’s big questions accessible and compelling. Each chapter opens with a surprising insight—not a mathematic formula, but a common observation. From there, the authors leapfrog over math and anecdote toward profound ideas about nature, art, and music. Coincidences is a book for lovers of puzzles and posers of outlandish questions, lapsed math aficionados and the formula-phobic alike.
