I don't remember how I got to Los Alamos. I didn't have a car, I'm sure but I don't remember how I got there. I don't remember. Maybe I took the train.

And in 1957, Los Alamos… it was the Cold War, and Los Alamos was very tightly shut. I think security was greater in '57 than it was during the war. You couldn't get anywhere near the place without clearance.

So I lived in the bachelor dormitory and I'm sure it was the same dormitory that was during the war, the conditions were the same. And we worked in the Theory Division Building, which had another level of security, and I had nothing to do. You know, nobody asked me to work on any nuclear weapons and I didn't know anything about nuclear weapons. And nuclear weapons were being worked on, but not where I was. But a friend of mine from Harvard was there and I came with a problem, with an interesting question, and I didn't have enough mathematical power to solve it, but he did. So the two of us spent the summer working on this problem in elementary particle physics, a very pretty problem.

And I met a lot of very distinguished guys who were there consulting, became very good friends with Francis Low of MIT, Marv Goldberger. I think Gell-Mann may have come through a few times, Ken Watson. And they were consulting on stuff.
