in fact there were occasions where I had to go to another department and Bardeen was left in the lab and he was anxious to get the experiment done and I said, ‘Well, there it is, John, I’ll be back in about an hour.’ And I’d come back in about an hour and John would be gone and I’d ask the other people in the lab what happened and they’d say, ‘Oh, he worked for about five minutes and said, “Oh, damn!” and left.’”
