I don’t know about you but I will be having a blast this week-end. Should your own outlook be bleak, you can watch the following very interesting videos from TED: Arthur Benjamin: Lightning calculation and other "Mathemagic" and Hans Rosling: Debunking third-world myths with the best stats you’ve ever seen.

Oh but are you, maybe, unfamiliar with TED? It stand for Technology, Entertainment, Design and describes itself as "The annual conference now brings together the world’s most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes)."
