The free lecture Galileo’s Telescopes and Observations – The Great Inflection Point in the History of Science presented by San Francisco Amateur Astronomers is Tuesday, March 21, 2017 from 7:45 pm to 9:30 pm at the Presidio Officers’ Club. Galileo Galilei significantly improved the optical performance of the telescope and began a series of celestial observations.
“This talk will lay out the key developments in the history of science related to astronomy preceding Galileo, describe in detail what is known about the optics and construction of his telescopes, and then discuss his observations and how they radically changed the science of astronomy.”
