A second test of Bell’s inequality, conducted by Holt and Francis Pipkin at Harvard, directly contradicted Clauser’s results—they found that Bell’s inequality held, suggesting that nature was local and quantum physics was wrong. Another experiment was needed to break the tie. At Berkeley, Clauser set up a modified version of Holt and Pipkin’s experiment, hoping again to find that quantum physics was wrong. Meanwhile, Ed Fry and Randall Thompson at Texas A&M University set up a similar experiment but used cutting-edge “tunable” lasers to dramatically cut down on the time needed to collect the
