THE TELESCOPE: Its History, Technology, and Future GEOFF ANDERSEN

The first documented patent for a telescope was awarded to spectacle maker Hans Lippershey. Galileo simply perfected the design. His true claim to fame stems from the fact that he used the telescope to make the observations that helped establish the idea of a sun-centered universe. Andersen, a research physicist, recounts the telescope's history and describes how a telescope works. He also explains why building an observatory is such an expensive endeavor and profiles the Hubble Space Telescope. Finally, Andersen lists some of the major discoveries made with telescopes, including Pluto and Halley's Comet, and profiles plans for future telescopes. Appendixes cover such topics as the basics of space-related math as well as tips for purchasing or constructing your own telescope. Princeton, 2007, 248 p., b&w images and color plates, hardcover, $29.95.
