In her graceful, compelling style, Dava Sobel chronicles the history of the Copernican Revolution, relating the story of astronomy from Aristotle to the Middle Ages. In its midst will be her play, And the Sun Stood Still, imagining the dialogue that would have transpired between Rheticus and Copernicus in their months together. As she achieved with her best sellers Longitude and Galileo's Daughter, Sobel expands the bounds of science writing, giving us an unforgettable portrait of scientific achievement.
