It's a Numberful World

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 UniverseWhy 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'Lighthearted and delightful . . . the ideal guide to math's multi-patterned treasures.' -Foreword ReviewsPublisher's note: It's a Numberful World was published in Australia under the title Woo's Wonderful World of Maths.
