Pythagoras and his cousins want to win a music contest, but first they must figure out how to play their instruments in tune, something that’s never been done before.
While trying to fix the problem, Pythagoras makes an important discovery–notes that sound pleasant together have a certain mathematical relationship. When Pythagoras applies this ratio to his cousins’ pipes and lyres, the result is music to the ears.

The Boy Who Loved Math: The Improbable Life of Paul Erdos
Author: Deborah Heiligman
Illustrator: LeUyen Pham
Synopsis by the author/publisher
Most people think of mathematicians as solitary, working away in isolation. And, it’s true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn’t learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made “Uncle Paul” a great man.
