Horn Book Review
Bring up the math term fractals in a roomful of adults, and it's likely quite a few eyes will glaze over. Yet wife-and-husband team Sarah and Richard Campbell (Growing Patterns: Fibonacci Numbers in Nature, rev. 5/10) succeeds in making fractals accessible and engaging to -- get this -- the elementary-school crowd. Sarah Campbell's writing is clear, fluid, and concise, effortlessly so. She starts off with familiar examples of man-made shapes, such as spheres, cones, and cylinders, as well as items in nature that approximate these perfect shapes (spherical tomatoes, conical icicles, cylindrical cucumbers). She then moves on to nature's "rough, bristly, and bumpy" shapes -- complex shapes ignored by scientists until Benoit Mandelbrot arrived on the scene, coining the word fractals in 1975. Mandelbrot noticed that the shapes of trees, broccoli, and ferns all share a common pattern: each has "smaller parts that look like the whole shape." Take broccoli, for example: as parts of a head of broccoli are lopped off, the smaller pieces look like the original whole head. Glossy, well-designed pages feature crisp, up-close photographs, which pair perfectly with the text -- making this the go-to choice for introducing fractals to children (and grownups). Included are a brief glossary, a "Make Your Own Fractal" activity, and an afterword by a Mandelbrot colleague. tanya d. auger (c) Copyright 2014.

Kirkus Review
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, cylindersshapes 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)]] Copyright Kirkus Reviews, used with permission.
