--places you can visit only with a microscope. For more than twenty-five years, Dennis Kunkel has been exploring these worlds. Through the lenses of powerful microscopes, he has examined objects most people have never even thought about: a mosquito's foot, a crystal of sugar, a grain of pollen, the delicate hairs on a blade of grass. Hidden Worlds takes you behind the scenes of Dennis's work and explains how he captures his remarkable images of microscopic life and objects. You'll learn how Dennis became interested in microscopes as a boy, how he prepares specimens for study, and how different kinds of microscopes work. You'll also have the chance to follow Dennis as he collects in the field--from the ash-covered slopes of Mount St. Helens to the lava tubes, rainforests, and beaches of his home state of Hawaii.
