Starred Review ALA Booklist (Sat Jun 01 00:00:00 CDT 2013)

Starred Review Though eccentric mathematician Paul Erdos might seem an unusual subject for a picture book, his story makes for a memorable biography. Growing up in Hungary during WWI, Erdos tried school but chafed at the rules and convinced his mother that he should study at home. He was fascinated by numbers from an early age, and by the time he was 20, he was known as The Magician from Budapest. Unable to do common tasks such as cooking, laundry, or driving, he spent his adult life flying around the world, staying with other mathematicians, and working collaboratively on challenging math problems. Math is woven into the lively writing (Mama loved Paul to infinity. Paul loved Mama to 8, too!). The wonderfully vivid artwork, where ideas from the text are clarified, also uses decorative elements to support the idea that Erdos saw the world differently merically. Heiligman appends a lengthy note about writing the book, while Pham offers a more extensive note on creating the illustrations, in which she comments on the mathematical ideas and mathematicians depicted in the art. This excellent picture-book biography celebrates a man little known outside his field, but one well worth knowing.

Heiligman presents the nomadic mathematician Paul Erdős as an appealing eccentric: for instance, Paul referred to children as "epsilons" ("a very small amount in math"). Each of Pham's illustrations is a puzzle for the reader to solve, with complex numerical concepts integrated into the pictures. While the overall layout is high in appeal, the font size is too small for the target audience.

Gr 3-6 Erd&6;s (19131996), 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 Erd&6;s 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 Erd&6;s, 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

An exuberant and admiring portrait introduces the odd, marvelously nerdy, way cool Hungarian-born itinerant mathematical genius. Heiligman's joyful, warm account invites young listeners and readers to imagine a much-loved boy completely charmed by numbers. Paul Erdos was sweetly generous throughout his life with the central occupation of his great brain: solving mathematical problems. Unmoored from the usual ties of home and family once grown, he spent most of his career traveling the world to work with colleagues. Erdos was known for his ineptness at practical matters even as he was treasured, housed and fed by those with whom he collaborated in math. The polished, disarming text offers Pham free rein for lively illustration that captures Erdos' childlike spirit. She uses a slightly retro palette and line to infuse Erdos' boyhood surroundings with numbers and diagrams, conveying the idea that young Paul lived and breathed math. She populates his adulthood with his affectionate colleagues, even including a graph with Erdos at the center of several dozen of the great mathematical minds of the 20th century to illustrate the whimsical "Erdos number" concept. An extensive author's note includes a bit more biographical information about Erdos and points to George Csicsery's 1993 film N is a Number as well as to Heiligman's website for links for further exploration. Pham's illustrator's note invites young readers to go page by page to learn about the kinds of numbers that captivated Erdos and to meet him among his cherished mathematicians. Social learners and budding math lovers alike will find something awesome about this exceptional man. (Picture book/biography. 3-9)
