Cosmic Discoveries: The Wonders of Astronomy Book

This is one of a series of books on science written by non-scientists. The series includes David Foster Wallace writing on infinity, amongst others. Vollmann has got Copernicus and seminal work "The Revolutions of the Heavenly Speres". One of the works which began to place the sun at the centre of the universe, rather than the earth.
The subject is not a straightforward one and you really have to be a fan of astronomy to be captivated by it, but Vollmann throws himself into it with gusto and a good deal of vigour. He examines the links between Copernicus and the classical writers who tackled the same subject, especially Ptolemy. He also examines the role of the Church and the scriptures in all this. Vollmann is quite self-deprecating at times and throws in a few good one-liners, mixing exegesis of the text with the technical stuff. Some of the technical stuff was beyond my mathematical and astronomical competence:
"Now, if we uncenter ourselves in obedience to the compelling circles and angles of 'Revolutions,' we'll come to see that the eccentric radius of any planet equals its relative mean distance from the Sun, while the epicyclic radius corresponds to Earth's relative mean distance from the same point. Never mind the fact that Ptolemy's eccentric radii for all four planets (and the Sun) equal 60 units while the epicyclic radii vary; this is simply an artifact of observations taken from a moving Earth rather than a relatively motionless Sun. The important fact is the ratio itself. For Mars, then, the ratio is 60 divided by 39*, or 1.518, a number which differs by less than 1 percent from the currently calculated mean Martian distance from the Sun of 1.524 astronomical units."
The exegesis is more interesting and typically Vollmann. Who else would check Calvin's collected works to see if he mentions Copernicus? The discussion is the most interesting part of the work, if you're interested in the subject. There is some interesting historical analysis too.
