Nuclear Diner: The Santa Fe Institute recently brought together physicists, historians, and social scientists to discuss the long-term legacies of the Manhattan Project. Among the participants at the 12â13 May conference were Harold Agnew, former director of Los Alamos National Laboratory and scientific observer on a plane that escorted the Enola Gay; Murray Gell-Mann, recipient of the 1969 Nobel Prize in Physics; Stan Norris, a historian and author of Racing for the Bomb; Gregg Herken, author of Brotherhood of the Bomb; and Gino Segrè, a nuclear physicist and author of several books on the history of science, including Faust in Copenhagen. Alex Wellerstein, a historian at the American Institute of Physics (which publishes Physics Today), writes about the event on his blog Restricted Data.
An ultracold atomic gas can sync into a single quantum state. Researchers uncovered a speed limit for the process that has implications for quantum computing and the evolution of the early universe.
