So I found myself in Caltech. It was a very interesting time. It was also a time for beginnings and in many ways I didn't like Caltech; in many ways Caltech wasn't good for me, but in many ways it was a dream place. Because the war was finished, the students were simply extraordinary; I mean my classmates. In aeronautics several students had been war heroes; they were colonels in the Air force and wanted to become generals so they would come to get degrees at Caltech to help themselves. There were very few people without experience; people had been touched by the war, in one form or another, very deeply. Then many works that had been done over the years during the war, and not published or not publicised, were becoming known. And it was like spring. It was something where, wherever you look, some flowers are coming from the fields. It was in '48 that Wiener's Cybernetics appeared and it had an extraordinary influence in my life. Wiener was a friend of my uncle, so I knew Wiener, at least I had at least met Wiener. It was also then - and that was more important perhaps - that Max Delbruck came to Caltech and started molecular biology. And so I spent two years there. The first year I was a fairly regular student; the second year I had decided it was a mistake and I was not going to stay, therefore I did the course of study, but opened up my horizons in many ways.
