Einstein's special theory of relativity? Didn't so much change the world as it did what we can know about the universe. Mar 17 05, 8:24 AM

As Arppy has said, Scientists call 1905 Albert Einstein's annus mirabilis -- his year of miracles. Within a few months, Einstein wrote a series of papers that would transform the way we see the universe. They included his theory of special relativity and the famous equation E=mc². As Einstein wrote in the introduction to his March paper, "According to the assumption to be contemplated here, when a light ray is spreading from a point, the energy is not distributed continuously over ever-increasing spaces, but consists of a finite number of energy quanta that are localized in points in space, move without dividing, and can be absorbed or generated only as a whole."
