Space Telescope Public Lecture Series Webcast - January 9, 2007
Hubble Space Telescope Public Lecture Series
at the Space Telescope Science Institute Speaker: Frank Summers, Space Telescope Science Institute Topic: Galileo's Dilemma: Ptolemy, Copernicus, and the Transformation of the Heavens Date: January 9, 2007 Time: 8 PM Eastern Place: Space Telescope Science Institute (STScI) Auditorium Price: Free admission and free parking Phone: 410-338-4700 Internet: http://hubblesite.org/about_us/public-talks.shtml In 1633, Galileo was tried under vehement suspicion of heresy for having promoted the Sun-centered view of the universe. His book was banned, he was forced to sign a recantation, and he lived under house arrest for the rest of his life. While the church is commonly portrayed as the antagonist, Galileo faced a much larger foe based entirely in science. During his life, the Earth-centered model of Ptolemy and the Sun-centered model of Copernicus were not readily distinguishable. In fact, Galileo's own work on transformation of reference frames provides the physical underpinnings of his astronomical dilemma. Lectures on a diverse selection of cosmic topics are held the first Tuesday of every month at 8 PM in the STScI Auditorium, located at 3700 San Martin Drive on the Homewood campus of Johns Hopkins University. Admission is free and free parking is available in the lot across the street. This lecture will be webcast live. The recorded webcast will also be available for viewing online the following day. To view the webcast, you may need to download and install software. See the web site listed below in advance for details. Further information and directions are available by calling 410-338-4700 or on the internet at: http://hubblesite.org/about_us/public-talks.shtml NEXT MONTH: February 6, 2007 Chris Burke, Space Telescope Science Institute Recent Results of Transiting Extrasolar Planets |
