Bound To Stay Bound

School Library Journal - 08/01/2022 Gr 4–6—An attempt to teach a complex concept to elementary age children in lay terms with photographic assistance to aid understanding. While Campbell breaks down infinity as a measure of endlessness in relation to mathematics and science with numerous examples, a lot of jargon prevents it from becoming accessible. She explains that infinity is not a single moment, but an idea. This philosophical understanding of infinity may be unfamiliar to some. The example of counting may help children process the concept partially, but they may not be able to differentiate between the two capacities of "big" and "endless." Although there is a wealth of paratextual elements that provide more details on infinity, specifically the author's note and a word problem, rather than comprehending the concept of infinity, children may be left more confused. This also raises a loaded question for young developing minds: can infinity simply be "figured out"? VERDICT A picture book that may serve as an introduction to infinity for upper elementary children, but its simple structure will limit its usefulness for middle graders.—Paige Pagan - Copyright 2022 Publishers Weekly, Library Journal and/or School Library Journal used with permission.

Booklist - 07/01/2022 *Starred Review* This picture book about the mathematical concept of infinity comes from the same team that previously tackled fractals (Mysterious Patterns, 2014) and Fibonacci numbers (Growing Patterns, 2010). As with those offerings, the authors take a complex abstraction and make it accessible to young readers through non-technical descriptions, relatable examples, and full-color, original photos that effectively reinforce the text. Even though the very idea of infinity seems overwhelming and even thinking about computing with infinity seems confounding, readers are encouraged to use their brains and stretch their imaginations. Applications include thinking of the biggest, highest number ever imagined—and adding one. Or taking an orange slice and cutting it in half, and then in half again and again, forever. These simple exercises serve as appealing introductions to basic calculus operations, and adult readers will find end notes providing a brief overview of infinity theory plus an accessible explanation of string theory. Additional back matter includes a glossary and further reading suggestions. Like the authors' previous titles, this current work offers solid math along with reassuring encouragement. This attractive offering will enhance STEAM collections and spark curiosity and conversation among young readers. - Copyright 2022 Booklist.
