[en] Howard Gordon, a physicist from the U.S. Department of Energy's Brookhaven National Laboratory, and local educators will separate the science facts from the science fiction of 'Angels and Demons,' a major motion picture based on Dan Brown's best-selling novel. The film, which opens nationally in theaters today, focuses on a plot to destroy the Vatican using antimatter stolen from the Large Hadron Collider (LHC) at the European particle physics laboratory CERN. Speakers will explain the real science of the LHC, including antimatter - oppositely charged cousins of ordinary matter with intriguing properties.
