====================== HES POSTING ====================== Greg Ransom's idea to talk about some concrete examples is an excellent one. I agree that the level of abstraction in the discussions often keeps us away from the kind of full understanding we would most like to have. But...I suspect that at this time in the semester most members won't be up to a protracted discussion in any case and definitely not up to reading something new. I also wonder how willing people will be to openly discuss someone's work, at length, in public? Just wondering.
