The boy who loved math [Book review]

Cory Doctorow has a review in Boing Boing of a book that he's read thrice already to his five year old daughter. The book is about mathematician Paulo Erdos, written by Deborah Heiligman, & illustrated by LeUyen Pham.

....with lively, fun illustrations of a young Erdős learning about negative numbers, becoming obsessed with prime numbers and leading his high-school chums on a mathematical tour of Budapest. They also go to great lengths to capture the upside and downside of Erdős's legendary eccentricity -- his inability to fend for himself and his helplessness when it came to everyday tasks like cooking and doing laundry; his amazing generosity and brilliance and empathy in his working and personal life.
