The speakers at one of the plenary sessions at the APS April Meeting were all Nobel laureates. 2011 laureate Saul Perlmutter of UC Berkeley (right) spoke about the work of his collaboration, the Supernova Cosmology Project, in discovering the acceleration of the expansion of the universe. He was followed by Adam Riess of The Johns Hopkins University (left), also a 2011 laureate, who described the work of the High-z Supernova Search Team in their independent discovery of the acceleration. The third speaker was 2004 laureate Frank Wilczek of MIT (center), who talked about the current status of the Higgs particle and its relationship to supersymmetry.
