of connection that I and others have been able to draw and we've been able to actually prove lower new lower bounds new limits on computing using this kind of connection so here's an outline for the rest of the talk I'll give you a very quick introduction to just boolean circuits and sort of the problems we're thinking about here I'll compare circuits to algorithms in the usual sense that people learn them and then I'll talk briefly at the end about how circuit analysis algorithms can imply circuit limitations okay all right so
