A complex man both in life and in his thinking, Nicolaus Copernicus gave the world one of its most important insights, one that would open up the heavens and earth for further scientific investigation: the theory that the earth and planets revolve around the sun. Copernicus' Secret deftly weaves together the scientific advances Copernicus made, the milieu in which he was working, and the details of his personal life in a wonderfully fascinating biography. 239 pages, softcover.
