From the latest Google newsletter:

Folks who visit the Googleplex in Mountain View, California often compare it to a college campus - there are people engaged in group meetings, in solitary work, and when they can, they make time to eat, play or exercise. One of the most campus-like elements is a thriving program called "Tech Talks" - regularly scheduled presentations offered by Googlers or our guests on a wide variety of subjects. AnyGoogler can attend a talk on, say, "Collecting Meteorites in Antarctica" or "High End Computing and Scientific Visualization at NASA." Now you can also watch these talks, just by searching GoogleVideo for [techtalks]. We obtain clearance from all speakers so TechTalks can be posted publicly, and will continue to add them to GoogleVideo. We hope you enjoy these sometimes obscure, always informative, insights into current events, research and ideas as much as we do.
