A Peek Inside the Cambridge Classroom

Below are four successive posts containing notes, thoughts, and quotes from some of the lectures and seminars listed in my post from last week (if you missed it, you can read the list here).  These posts came at popular request, but I was already composing the drafts to post anyway.  I think it's about time you see what I'm up to out here.  If you would prefer not to read them all, look through the posts and read only the ones that interest you; you will see a brief description of the post at the top of each one.  I hope you enjoy :)
