The Boulder Astronomy & Space Society is dedicated to the interests of the observers and space enthusiasts of all types in Boulder, Colorado. It is our goal to provide common ground for Boulder's amateur, professional, and academic communities to share their enthusiasm about the universe around us. Our meetings are generously hosted on the University of Colorado campus at Fiske Planetarium and Sommers - Bausch Observatory and are open to students and the public alike. See the Events page for more details.

Discussion Topic: "Special and General Relativity Foundations ". We all know the terms, but how many of us understand the foundation that Einstein used to develop these theories. We'll discuss the logic and a little of the mathematics that Einstein used to formulate his famous theories and hopefully gain some appreciation for why they stand on such strong footing today for large scale, and why they brake down on quantum scales.
Note that we have moved Forum Astronomique to the second Tuesday of the month for 2009.
