Actor Alan Alda (shown center) came to SLAC on Friday, September 26, to film an episode of the awarding-winning PBS science series Scientific American Frontiers. Alda, who hosts the program, interviewed Persis Drell (shown right), Director of Research at SLAC, and Roger Blandford (shown left), Director of the Kavli Institute for Particle Astrophysics and Cosmology, for a program on the ‘Dark Side of the Universe’. The program will air in 2004. After taping an interview at the SLD Detector, Alda visited the two-mile long Klystron Gallery, where he drove an electric cart, remarking that the ride was the most fun he’d had in years.
