"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 . . . For visual learners, this is a particularly accessible demonstration of an intriguing concept." --"Kirkus Reviews"
