How Copernicus Revolutionised the Cosmos
9781408818008   Product Code: 23937
In 1510, Copernicus had begun to formulate the theory that placed the Sun rather than the Earth at the centre of our universe. The theory was potentially heretical and not until 1539, when a young German mathematician named Rheticus sought him out, was Copernicus persuaded to publish On the Revolutions of the Celestial Spheres. Dava Sobel tells the story of the great astronomer, and where the evidence runs out, she imagines the meeting between Rheticus and the older scientist.
