The Boy Who Loved Math: The Improbable Life of Paul Erdos

Gr 3-6--Erdos (1913-1996), the Hungarian-born son of two math teachers, displayed his fascination with numbers early on. Before entering school he could calculate the number of seconds a person had lived just by asking the time and date of their birth. Unable to sit still and follow rules in school, he was homeschooled by his mother. High school was a better fit, and he made friends with students who shared his love of math. His skills became famous, but Erdos didn't know how to do laundry, cook, or even butter his own bread. He "didn't fit into the world in a regular way." So, he created a life that fit him instead. For years he flew around the world, his modest belongings in two suitcases, working with other noted mathematicians. They worked on number and set theory as well as new ideas like combinatorics and the probabilistic method. Some of their efforts led to the better computers and search engines that we use today. The well-researched text and painstakingly accurate illustrations (in terms of setting and mathematics) provide a fascinating introduction to the man. The oversize eyes of the characters give many of them, especially Erdos, a rather maniacal look that is off-putting. The extensive endnotes provide much information and would be useful in a classroom setting. That may be the most likely scenario for exposing children to this picture-book biography. Only the most mathematically devoted would pick it up on their own.--Sara-Jo Lupo Sites, George F. Johnson Memorial Library, Endicott, NY

As a boy in Budapest, Paul Erdos (1913-1996) had problems to solve, but they didn't involve math. Rules were a problem, and school was another: "Paul told Mama he didn't want to go to school anymore. Not for 1 more day, for 0 days. He wished he could take days away--negative school days!" Heiligman and Pham cleverly incorporate mathematical references through this story, which follows Erdos from a numbers-obsessed boy to a numbers-obsessed man who flouted societal norms and couch-surfed the globe--other mathematicians were honored to have him as a guest for the chance to talk math with him. Erdos's unconventional brilliance shines through on every page, and extensive author and illustrator notes (including Pham's explanations of the mathematical concepts she works into each illustration) will delight readers with even a fraction of Erdos's interest in math. Ages 3-8. (June)
