We formed a team. We formed a not-for-profit academy called The Teachers Academy in Chicago, and we were trying to set up a model for changing all the cities in the United States. I mean, my own research is in particle physics, which involves huge accelerators, and we learned from that, that you might as well do it right by doing the whole system. So here we are in the third largest school system in the nation, Chicago, trying to re-train all the teachers. Not a teacher in one school here, or two schools, or ten schools, or fifty schools, but 600 schools, all the teachers in Chicago. Re-train them in ways of teaching math and science that are delightful because it’s a wonderful way to start a kid in being interested in learning.
