“In Mysterious Patterns: Finding Fractals in Nature, Sarah C. Campbell, aided by photographs she and her husband, Richard P. Campbell took, explains what does (lightning) and doesn’t (a swallowtail caterpillar’s markings) constitute a fractal. She delivers a tidy education, gives a nod to the use of fractals in the built world, and offers the hope that readers will invent new uses.”
