Welcome to Caltech's Streaming Theater page.

This site houses streaming video of many of the programs that were available to the Caltech community from 1999 to the present. Most of these events took place on campus in Beckman Auditorium, and feature Caltech faculty, students, or distinguished visiting speakers.

For browsing ease, the offerings have been sorted into three general categories.

• Science and Technology includes (among many other topics) the popular Watson Lecture Series and the Everhart graduate student lectures, as well as the informative "Earthquakes 101."
• Campus Life showcases campus events such as Caltech's annual commencement ceremonies and Mechanical Engineering 72 competitions.
• Society and Culture encompasses varied topics including documentary filmmaking, voting technology, national defense, and diversity in science education.

To view webcasts offered by the Jet Propulsion Laboratory (JPL), please see their Events site. To view webcasts offered by the Spitzer Space Telescope and NASA TV, please see the News Room site.

To view these streams you will need to download Real Player. For help deciding which version of Real Player is best for your system, please see our help page.

Many Watson Lectures are available for purchase on DVD. To request a copy, fill out the DVD Order Form (PDF).

	Anneila Sargent: CARMA: Raising Our Sites 4/16/2008 [56k modem] [cable/DSL] [broadband] 53 minutes In a Watson Lecture on April 16, Anneila Sargent discussed how Caltech radio astronomers have connected OVRO millimeter-wave telescopes with others from the Berkeley-Illinois-Maryland array to create an instrument that will provide new views of the universe. Sargent is director of the Owens Valley Radio Observatory, as well as Caltech's vice president for student affairs and the Rosen Professor of Astronomy.
	Ari Stern: Symmetry and Simulation: How Geometry Affects Scientific Computing from the Solar System to your Microwave Oven 4/2/2008 [56k modem] [cable/DSL] [high resolution] 61 minutes Ari Stern, a Caltech graduate student in applied and computational mathematics, discussed how scientists model change in physical systems. He explained how solving differential equations allows researchers to make predictions about the future, or even the past. However, since it is impossible or impractical to obtain exact solutions in most complex systems in science and engineering, we must rely on numerical simulation to compute approximate answers.
	Yu-Chong Tai: The Next-Generation Neural Implant: Let's Start with Retinal Implant 3/12/2008 [56k modem] [cable/DSL] [broadband] 42 minutes In a Watson Lecture on March 12, Yu-Chong Tai discussed the technology of retinal implants and recent progress in their development. More Americans than ever are facing the threat of blindness from age-related eye diseases including macular disease and retinitis pigmentosa, and retinal implants could provide a solution to this problem. Tai is a professor of electrical engineering and mechanical engineering and executive officer for electrical engineering at Caltech.
