Colloquium and Sigma Series Lectures The Colloquium and Sigma Series Lectures provide monthly presentations related to science and technology.
	Purpose The Colloquium Lectures at NASA Langley provide monthly lectures and demonstrations related to science and technology. These lectures stimulate the creative processes of Langley employees, and enhance the quality of life at Langley by providing more opportunities for learning. These lectures are open to NASA employees, NASA contractors, and other invited guests. The Researcher News Online has a recent article about the history of the Colloquium and Sigma Series Lectures: November 17, 2006 The Sigma Series Lectures, presented at the Virginia Air and Space Center in downtown Hampton, provide to the general public this same opportunity for exposure to interesting technical topics. These lectures, however, are usually at a somewhat less detailed level, because the audience may consist of people with non-technical backgrounds in addition to local high school and college students. The guests and topics for both the Colloquium and Sigma Series Lectures are selected by a committee of NASA Langley employees representing the different technical organizations at the Center. If you have a suggestion for a future lecture topic, please send your suggestion to Susan Palmer (s.o.palmer@larc.nasa.gov).

	Viewing Past Lectures DVD recordings are currently made of all Colloquium Lectures, and many of the past lectures were also recorded (VHS, Beta, or audio cassette). These recordings can be borrowed, by employees and contractors of NASA Langley Research Center only, from Langley's Technical Library (x42389). A list of past colloquium lectures is available to help you select which lectures you'd like to catch up on.
