Never have those words been so true. And walking in the sand will never be the same after seeing these photographs.
Professor Gary Greenberg painstakingly sorts through grains of sand to find the most remarkable ones to photograph. He has also developed a complicated technique for photographing each grain from dozens of angles and combining the images with special software.
The grains are magnified 250 times to reveal fragments of crystals, spiral fragments of shells and crumbs of volcanic rock.
The images are available in Greenbergs book A Grain of Sand and on his website sandgrains.com.
