That poor guy, he's got the weight of the world bearing down on him. So nervous. Everyone's looking at him. But what he is talking about is so completely fascinating. I want to thank him for talking about it. I want to thank MIT for making brilliant stuff like this available to all of us for free.
All of the lectures are absolutely fascinating. There is a student named Lativ or something, who asks tough questions which are interesting too. I recommend this to all fellow hackers.
On a side note, I am currently reading "Metamagical Themas" (http://en.wikipedia.org/wiki/Metamagical_Themas), written by Douglas Hofstadter, who also wrote the book "Gödel, Escher, Bach: an Eternal Golden Braid".
"Metamagical Themas" is a very good read about a ton of different subjects, from self-referential sentences to Lisp.
This is great. I found audio files of this in the past, but without being able to see what was going up on the board, it wasn't really useful.
