It's a Numberful World : How Math Is Hiding Everywhere

A 2021 Mathical Honor Book: "One of the best math teachers on the planet. His book is as buoyant, open-hearted, and energetic as he is." -Steven Strogatz, New York Times-bestselling author of Infinite Powers: How Calculus Reveals the Secrets of the Universe

Why aren't left-handers extinct? What makes a rainbow round? How is a pancreas like a pendulum? These may not look like math questions, but they are-because they all have to do with patterns. And mathematics, at heart, is the study of patterns.

That realization changed Eddie Woo's life-by turning the "dry" subject he dreaded in high school into a boundless quest for discovery. Now an award-winning math teacher and a YouTuber with nearly two million subscribers, Woo sees patterns everywhere: in the "branches" of blood vessels and lightning, in the growth of a savings account and a sunflower, even in his morning cup of tea! Here are twenty-six bite-size chapters on the hidden mathematical marvels that encrypt our email, enchant our senses, and even keep us alive-from the sine waves we hear as "music" to the mysterious golden ratio. This book will change your mind about what math can be. We are all born mathematicians-and it's a numberful world.

"Introduces mathematical vocabulary in a fun and approachable way. . . . A gentle but enthusiastic introduction to a wide variety of interesting mathematical topics." -Mathematical Association of America
