I want today to talk about the industrial revolution from a variety of, of aspects. I put everything on the board, I put on our website, so don't worry about copying it down. And it's all pretty, pretty obvious doing the industrial revolution across this century is no easy task. But we will do it and do the reading. Let me just say that to the way people look at what used to be called the industrial revolution and I guess some people still call it that has changed dramatically through the 1950s and into the 1960s, the idea of the industrial revolution was that it was the work of some genius inventors who created mechanism machines in the used primarily in the textile industry, but also in mining that eliminated blocks to assembly line production. And then everybody was crowded into factories and the new brave world opened up. In fact, one of the most interesting books and so great classics is still in print was written by an economic historian at Harvard, who's still around called David Landis, a good book called the unbound Prometheus, which was basically that and some of the inventions that II briefly describe in your reading, the spinning Jenny, et cetera. I refer to that. Well, And then that kind of analysis LED one to concentrate on.
