Albert Einstein changed the way physicists view the universe - and transformed the way we all see the world. His Theory of Relativity stunned scientists, but it is integral to modern thought as the important scientific discovery of the twentieth century. This volume collects Einstein's own writings on the Theory of Relativity.
Stephen Hawking explains how such great men of science as Copernicus, Galileo, Kepler, Newton and Einstein built on the discoveries of those who came before them, and how these works changed the course of science, ushering astronomy and physics out of the Middle Ages and into the modern world.
