MYSTERIOUS PATTERNS

FINDING FRACTALS IN NATURE

Through examples of what fractals are and what they aren’t, this photo essay introduces a complex mathematical idea in a simple, inviting way.

Using a straightforward text and eye-catching photographs, the Campbells start with the familiar: spheres, cones, cylinders—shapes readers can find and readily name in their environments. But then they move on to the more elaborate forms: a head of broccoli, the flower of a Queen Anne’s lace, a tree. In 1975, Benoit Mandelbrot gave a name to natural shapes with smaller parts that look like the whole shape. He called them fractals. Photographs of whole and divided flower and broccoli heads, set on plain backgrounds, demonstrate how smaller parts repeat the shape of the whole. A double-page spread of forked lightning shows another example. Even mountain ranges are made of smaller mountains. Further, smaller images remind readers that the shapes can be called fractals only if the repeating parts diminish in size. In conclusion, the author of Growing Patterns (2010) provides instructions for drawing the interesting fractal pattern that surrounds each page number. An afterword by mathematician Michael Frame offers more information about Mandelbrot and introduces the possibility of a real-world application of this abstract idea: invisibility cloaks!

For visual learners, this is a particularly accessible demonstration of an intriguing concept. (Informational picture book. 5-9)

Informative, empowering, and fun.

ROX'S SECRET CODE

Girl power abounds in this book about coding that introduces young readers to the world of programming while offering them hands-on activities via a companion app.

In this title that was first introduced as a customizable, personalized print-on-demand product, Rox has a superpower. Using code, she programs toy robots that can do things like make broccoli disappear—or mischief. When Dad tells Rox to clean her room, she quickly thinks up a bot that will do it for her, writing code that instructs her bot to use artificial intelligence to sort objects by color and type. Though Rox knows that there’s a high potential for her creation to rebel, the perks outweigh any potential adverse effects. Rox’s robot has her room neat and tidy in no time—and then the entire home. Chorebot’s AI allows it to keep learning, and it seems Chorebot can do no wrong until the robot decides to rearrange the entire city (both buildings and people) by type, style, and gender. Chorebot goes “out of his artificial mind!” Rox must now stop her creation…without the assistance of the internet. The artwork, styled in the tradition of popular superhero series, is peppy and colorful, and it depicts Rox as an adorable black girl donning a black bomber jacket and a pink tutu. A companion app (not available for review) allows readers to create a bot of their own.

Informative, empowering, and fun. (Picture book. 5-8)

A retro-futuristic romp, literally and figuratively screwy.

ROBOBABY

Robo-parents Diode and Lugnut present daughter Cathode with a new little brother—who requires, unfortunately, some assembly.

Arriving in pieces from some mechanistic version of Ikea, little Flange turns out to be a cute but complicated tyke who immediately falls apart…and then rockets uncontrollably about the room after an overconfident uncle tinkers with his basic design. As a squad of helpline techies and bevies of neighbors bearing sludge cake and like treats roll in, the cluttered and increasingly crowded scene deteriorates into madcap chaos—until at last Cath, with help from Roomba-like robodog Sprocket, stages an intervention by whisking the hapless new arrival off to a backyard workshop for a proper assembly and software update. “You’re such a good big sister!” warbles her frazzled mom. Wiesner’s robots display his characteristic clean lines and even hues but endearingly look like vaguely anthropomorphic piles of random jet-engine parts and old vacuum cleaners loosely connected by joints of armored cable. They roll hither and thither through neatly squared-off panels and pages in infectiously comical dismay. Even the end’s domestic tranquility lasts only until Cathode spots the little box buried in the bigger one’s packing material: “TWINS!” (This book was reviewed digitally with 9-by-22-inch double-page spreads viewed at 52% of actual size.)

A retro-futuristic romp, literally and figuratively screwy. (Picture book. 5-7)
