The class will be organized as a true seminar and I expect active and vocal participation from those who sign up. This is not a class where I know the answers and I'm trying to teach you. Rather, in giving the class I'm hoping to learn quite a bit myself.
You can take 291 for two units or for four, with those taking it for four being expected to do a course research project -- broadly defined and upon our mutual agreement. There are no pre-requisites per se, but there is lots of background material that we will, at best, skim.
In general, subject to space, I'm also happy to have people drop in (faculty welcome as well) but I will expect you to participate if you're there.
