Stargazer: The Life and Times of the Telescope

It's perhaps surprising that an instrument as seemingly simple as the telescope has had a large impact on human history, from changes in warfare to helping us understand our place in the cosmos. Watson, the astronomer in charge of Australia's largest optical telescope and a science writer, provides a fine overview of the 400-year history of this invention. He's strongest when discussing the people most responsible for moving the field of astronomy forward, controversies surrounding their inventions and the complexities of their lives. From Tycho Brahe, the brilliant early Danish astronomer, to locomotive builder Andrew Barclay, whose telescopes were so flawed that he was convinced Saturn looked "like a half-eaten apple," Watson relates intriguing stories while providing them with a rich cultural context. While still interesting, the work is less compelling when Watson provides specifics about the physics and optics of telescopes. And with so much ground to cover, he rarely delves deeply and provides little if any new information. Yet gathering all of this material in one place and presenting it in such an engaging style is a considerable accomplishment. B&w illus. (Aug. 1)
