Jason and Igor: I'm not going to make up deadlines to look at each chapter, but I will march ahead, giving lectures on each chapter and then moving on to the next one... and I will focus most of my attention on discussions about what I just discussed, though people are free to continuing each topic _ad infinitum_.

There will be a discussion thread about each chapter, and one about each lecture, and perhaps one about each exercise (or group of related exercises?)
