2021 Mathical Honor Book
Why aren’t left-handers extinct?
What makes a rainbow round?
How is a pancreas . . . like a pendulum?
Publisher's note: It's a Numberful World was published in Australia under the title Woo's Wonderful World of Maths.
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, 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.
Eddie Woo is the head mathematics teacher at Cherrybrook Technology High School in Sydney, Australia. He has been teaching mathematics for more than ten years. In 2012, Eddie started recording his lessons and uploading them to YouTube—creating “Wootube.” Since then, he has amassed a following of more than 600,000 subscribers, and his videos have been viewed more than 33 million times. In 2018, Eddie received Australia’s Local Hero Award and was named one of the top ten teachers in the world as a finalist for the Global Teacher Prize.
