       | It's funny to see this on the front page of HN. I knew Chinmay
       | (one of the authors of the paper) back when he was an undergrad
       | at Caltech. Super cool dude - I knew he'd go on to do great
       | stuff! Very happy for the team that obtained this result.

       | virtually impossible to calculate. "It tells us that the thing
       | that seemed unlikely to be true is true," said Isaac Kim of the
       | University of California, Davis. "Albeit in some very weird
       | system.""
