Watch documentary "A Grain of Sand" by Dr Gary Greenberg
Every grain of sand in the world is unique and beautiful when viewed through the microscope. If each grain of sand is so beautiful and unique, imagine how beautiful and unique each person is? Artist, inventor, and scientist, Dr Gary Greenberg has devoted his life to revealing the secret beauty of nature. Beginning his career as photographer and filmmaker, he worked on the first Superman film where he transformed human pancreatic cancer cells into the planet Kyrpton. After earning a Ph.D. in biomedical research, he went on to invent the high-definition, three-dimensional light microscope, for which he was issued eighteen US patents.
