***.... Stone, a PhD mathematician from Stanford, acknowledged that his star staff member (John Pike) attended Vanderbilt but never got a degree. "I view him as the Edwin Land of our community - Land never graduated from Harvard. He was a great genius, and he didn't have time for college," Stone said. "John didn't have time for anything that didn't interest him. As opposed to working on lost causes, John works on things that are ripe for media attention - and he's been far more successful at managing the media than any scientist at FAS."

Not knowing who the heck John Pike is, I'm going to go way out on a limb and say that he has clearly never worked under contract to NASA.
