If we would only stop and smell the roses once in a blue moon, we'd discover some amazing things on this planet. Why are wildflowers so brightly colored? To attract the attention of honeybees, of course. Why are flamingos pink? Because of the pigments in the crustaceans they eat. Perhaps only a physics professor would know that you can tell the age of a desert by the color of its sand--perhaps only a physics professor would care--but it doesn't take a rocket scientist to appreciate the photographic skills Neill employs in illustrating the authors' concepts.
