Galileo's Telescope by Massimo Bucciantini

A very well-documented book about Galileo and the astronomical revolution caused by his telescope and his observations. While he did not invent the telescope, his improvements and observations were new. He also was famous and published quickly. Though there was resistance and skepticism, the discoveries actually moved across the world with amazing rapidity. The book is heavy on personalities and somewhat light on the technical but a good book overall.
