I played a lot of tennis with Francis. We played in a tournament, actually, Francis, in a doubles tournament, and were beaten by Rusty Ball and his son. Rusty Ball was a tennis player from.... somewhere in New Mexico, and they beat us pretty bad.

And toward the end of the summer, Francis said, 'Well, I can’t play with you next week.' I said, 'Oh, that’s too bad.' He said, 'Yes, I’m going to Nevada to watch nuclear weapons test.' I said, 'I didn’t know you were working on nuclear weapons.' He said, 'No I’m not, but I was interested and I asked Carson Mark and Carson Mark asked me if I’d like to go, and I said yes, I was curious.' I said, 'Geez, could I go?' He said, 'Well, you have to ask Carson.'

So I went and asked Carson, and Carson liked what I’d done in the summer, that I’d worked on this pure physics problem, which I was going to publish, the two of us were going to publish from Los Alamos. He thought it was good, because Los Alamos had the reputation as a bomb factory and here are these guys working on this nice physics problem. So he said, 'Yes, you can come, but the only thing is you have to pay your own way, and the airfare.' I said, 'That’s fine, I’ll do that.'
