Video Clips at Lawrence Berkeley National Laboratory press conference regarding Prof. Saul Perlmutter's Nobel Prize. UC Berkeley Chancellor Robert Birgeneau introduces Perlmutter, 52, a professor of physics at the University of California, Berkeley, and a faculty senior scientist at Lawrence Berkeley National Laboratory (LBNL), led one of two teams that simultaneously discovered the accelerating expansion of the universe. Perlmutter led the Supernova Cosmology Project that, in 1998, discovered that galaxies are receding from one another faster now than they were billions of years ago. He shares the Nobel Prize with Adam G. Riess, 41, of The Johns Hopkins University and Brian Schmidt, 44, of Australian National University's Mount Stromlo and Siding Spring Observatories, two members of the competing High-Z Supernova Search team. When the discovery was made, Riess was a postdoctoral fellow at UC Berkeley working with astronomer Alex Filippenko, who at different times was a member of both teams.
