The German-born physicist Albert Einstein (1879–1955) explained the Michelson-Morley experiment. In 1905—sometimes called Einstein’s “year of miracles”—he published a series of scientific discoveries that forever changed the entire scientific view of the universe. He explained a biological phenomenon called Brownian motion, the electromagnetic phenomenon called the photoelectric effect, and the results of the Michelson-Morley experiment. For this he devised a new “special theory” of relativity, showing that matter and energy were related by the equation E = mc2.
