Thanks a lot. I’d seen the Baez-Dolan lectures but not the others.

Anon, I was thinking of [this clip](http://www.youtube.com/watch?v=S6J9uyRKiRI) and similar ones, but by extension also of great clips of lectures. Perhaps I'll do a post on my favorite online-lectures, but for now, have a look at David Ben-Zvi's lectures on representation theory and topological field theory (you'll need to print the notes first to follow the clips but the content is great!). And there are many more examples, one more the lectures by Baez and Dolan on geometric representation theory.

You say that these days one can get a grasp of difficult concepts in Algebraic Geometry by watching youtube videos. Could you provide some links? I haven’t found any. Thanks

Is there a connection to Waldhausen’s “brave new rings”?

Dear Lieven, this is a very original article: I have never seen such a profound and detailed exegesis of a mathematical picture before. It will be a tremendous help to beginning algebraic geometers and to older ones it may bring fond bitter-sweet (“Tempus fugit”) memories. Thank you for this fine, erudite blog. Vriendelijke groeten, Georges.
