THE BOY WHO LOVED MATH

THE IMPROBABLE LIFE OF PAUL ERDOS

Social learners and budding math lovers alike will find something awesome about this exceptional man.

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)

ADA TWIST AND THE PERILOUS PANTS

From the Questioneers series , Vol. 2

Adventure, humor, and smart, likable characters make for a winning chapter book.

Ada Twist’s incessant stream of questions leads to answers that help solve a neighborhood crisis.

Ada conducts experiments at home to answer questions such as, why does Mom’s coffee smell stronger than Dad’s coffee? Each answer leads to another question, another hypothesis, and another experiment, which is how she goes from collecting data on backyard birds for a citizen-science project to helping Rosie Revere figure out how to get her uncle Ned down from the sky, where his helium-filled “perilous pants” are keeping him afloat. The Questioneers—Rosie the engineer, Iggy Peck the architect, and Ada the scientist—work together, asking questions like scientists. Armed with knowledge (of molecules and air pressure, force and temperature) but more importantly, with curiosity, Ada works out a solution. Ada is a recognizable, three-dimensional girl in this delightfully silly chapter book: tirelessly curious and determined yet easily excited and still learning to express herself. If science concepts aren’t completely clear in this romp, relationships and emotions certainly are. In playful full- and half-page illustrations that break up the text, Ada is black with Afro-textured hair; Rosie and Iggy are white. A closing section on citizen science may inspire readers to get involved in science too; on the other hand, the “Ode to a Gas!” may just puzzle them. Other backmatter topics include the importance of bird study and the threat palm-oil use poses to rainforests.

Adventure, humor, and smart, likable characters make for a winning chapter book. (Fiction. 6-9)

IZZY GIZMO AND THE INVENTION CONVENTION

From the Izzy Gizmo series

A disappointing follow-up.

Inventor Izzy Gizmo is back in this sequel to her eponymous debut (2017).

While busily inventing one day, Izzy receives an invitation from the Genius Guild to their annual convention. Though Izzy’s “inventions…don’t always work,” Grandpa (apparently her sole caregiver) encourages her to go. The next day they undertake a long journey “over fields, hills, and waves” and “mile after mile” to isolated Technoff Isle. There, Izzy finds she must compete against four other kids to create the most impressive machine. The colorful, detail-rich illustrations chronicle how poor Izzy is thwarted at every turn by Abi von Lavish, a Veruca Salt–esque character who takes all the supplies for herself. But when Abi abandons her project, Izzy salvages the pieces and decides to take Grandpa’s advice to create a machine that “can really be put to good use.” A frustrated Izzy’s impatience with a friend almost foils her chance at the prize, but all’s well that ends well. There’s much to like: Brown-skinned inventor girl Izzy is an appealing character, it’s great to see a nurturing brown-skinned male caregiver, the idea of an “Invention Convention” is fun, and a sustainable-energy invention is laudable. However, these elements don’t make up for rhymes that often feel forced and a lackluster story.

A disappointing follow-up. (Picture book. 3-6)
