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)

Outstanding—a breath of fresh air, just like Rocket herself.

ROCKET SAYS LOOK UP!

Rocket is on a mission…to get her angst-y teen brother to put down his cellphone and look up.

An aspiring astronaut, Rocket makes it a point to set up her telescope and gaze at the stars every night before bedtime. Inspired by Mae Jemison, Rocket, a supercute black girl with braids and a coiffed Afro, hopes to be “the greatest astronaut, star catcher, and space walker who has ever lived.” As the night of the Phoenix meteor shower approaches, Rocket makes fliers inviting everyone in her neighborhood to see the cosmic event at the park. Over the course of her preparations, she shares information about space-shuttle missions, what causes a meteor shower, and when is the best time to see one. Jamal, Rocket’s insufferable older brother, who sports a high-top fade and a hoodie, is completely engrossed in his phone, even as just about everybody in the neighborhood turns up. The bright, digital illustrations are an exuberant celebration of both space and black culture that will simultaneously inspire and ground readers. That the main characters are unapologetically black is made plain through myriad details. Rocket’s mother is depicted cornrowing her daughter’s hair with a wide-toothed comb and hair oil. Gap-toothed Rocket, meanwhile, makes her enthusiasm for space clear in the orange jumpsuit both she and her cat wear—and even Jamal’s excited by the end.

Outstanding—a breath of fresh air, just like Rocket herself. (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)
