It was now May 1953, and June–in fact June and July 1953–the time when I went down to Urbana to work with Francis on what some people called the renormalization group. What happened was that Sam Allison's secretary had forgotten to send in a renewal of the notification to my draft board that I was working in a scientific laboratory and my… and that I should continue to receive a draft deferment. So, when I came back to Chicago I received a draft notice, and I thought I was going to be drafted and sent over to Korea and so on. I wasn't so terribly concerned about that in itself, but I was worried that I wouldn't be able to do any more work on physics for a long time, and… but in the mean time I tried to correct the error and get myself undrafted, but I decided I’d better write up some ideas before leaving for the army. And so I put together a written version of this idea and sent it in to the Physical Review Letters–well Physical Review. It was a letter to the Physical Review, at that time there wasn’t a separate 

[Q] There wasn't a separate journal?

There wasn't a separate journal; it was a letter to the Physical Review. I worked on it in Val Telegdi's lab, which was air-conditioned for the sake of equipment. There was no air-conditioning, as I said before, for the sake of people. I thought of getting a wax pencil;  it would be a very important part of my equipment, and it would melt when the temperature was over ninety, so that I could get air-conditioning for my equipment, but that didn't work. Anyway I worked in Val's lab–he later put up a plaque over the desk where I wrote up this stuff.
