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.

Or what kind of insect has ears on its knees? Busy Builders features eight insects, one spider, and an inside look at the unique structures they each build. Roxie Munro's striking art, drawn in India ink and colored ink, brings these remarkable feats of engineering into full focus. A glossary and resources to learn more are included. If you were a bug, what kind of home would you build?
