In 1539 a young German mathematician, Georg Joachim Rheticus, travelled to Frombork to meet Copernicus; months later he departed with the manuscript for the book that would change the way we understand our place in the universe. Rheticus arranged for the publication of De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres) - legend has it Copernicus received a copy on his deathbed. This book would forever change the way we thought about our place in the universe. In her compelling style, Dava Sobel chronicles the history of the Copernican Revolution, relating the story of astronomy from Aristotle to the Middle Ages.
