A bit long, but it's worth it. I didn't manage to watch the whole thing before I received a streaming error. Oh well, erm, maybe I should pick up a textbook to read now then...

This guy's a great lecturer, by the way. I've seen his lecture on The Sounds of Music, and it was really interesting!

I like the last bit of that where he speaks with a mickey mouse voice when he inhaled helium...
