“See the world in a grain of sand,” wrote the poet William Blake. The photographs taken by Dr. Gary Greenberg make that amazingly easy to do.

Using microscopes that he designed and invented, Greenberg has magnified and photographed. His images reveal that what we may think of as trillions of identical “grains” are really a colorful array of tiny fossils, bits of minerals, and pieces of coral and shells.

You can see more of his photographs at http://www.sandgrains.com. He has even photographed sand from the Moon!
