In January 1963 I started a half academic year in Cambridge, Massachusetts at MIT, and I was being offered a position at… either at MIT or at Harvard or at a mixture of the two. And I was very seriously considering taking it. Murph Goldberger was there on leave also, and Francis Low was there because he was a professor at MIT. And the three of us worked together on some very laborious calculations, which were however interesting - and we drew in a couple of other people. We drew in Fred Zachariasen and a couple of post-docs from Caltech, and so on, into some of the detailed calculations. But the idea had to do with… again with some of Geoffrey Chew's principles–dog… dogmata, whatever you want to call them! He had the idea that the particles in quantum field theory were fixed angular momentum poles, and that the particles in hadron bootstrap theory would be moveable poles on Regge trajectories, accompanied poles accompanied by cuts of course in the angular… complex angular momentum plane. And I didn't see any particular reason for this dogma to hold, and what we noticed was that in quantum field theory, with vector bosons--a form of quantum electrodynamics for example with massive photons, something of that kind–the fixed pole in the angular momentum plane for the electron, say, actually moved when you included higher order radiative corrections.
