Here is the world viewed within a grain of sand, thanks to the stunning three-dimensional micro-photography of Dr. Gary Greenberg. To some, all sand looks alike--countless grains in a vast expanse of beach. Look closer--much closer--and your view of sand will never be the same. Employing the fantastic micro-photographic techniques that he personally developed, Greenberg invites you to discover the strange and wonderful world that each grain of sand contains. See, truly see, the sands of Hawaii and Tahiti, the Sahara and the Poles, a volcano, each exquisitely different, and each telling a fascinating geological story.
