Moving heaven and earth : Copernicus and the solar system

When Nicolaus Copernicus claimed that the Earth was not stationary at the centre of the universe but circled the Sun, he brought about a total revolution in the sciences and consternation in the Church.Copernicus' theory demanded a new physics to explain motion and force, a new theory of space, and a completely new conception of the nature of our universe. He also showed for the first time that a common-sense view of things isn't necessarily correct, and that mathematics can and does reveal the true nature of the material world. As John Henry reveals, from his idea of a swiftly moving Earth Copernicus sowed the seed from which science has grown to be a dominant aspect of modern culture, fundamental in shaping our understanding of the workings of the cosmos.
