"Most men and women, by birth or nature, lack the means to advance in wealth and power, but all have the ability to advance in knowledge." - Pythagoras

I've been searching for a way to review various mathy-things, and just through dumb luck found this fab-o site: http://www.khanacademy.org/

(found it through the subreddit "askscience", which is also fab-o)

Not just math, lots of other very nifty stuff!

(though I can't help but hear Captain Kirk holler every time I read "Khan Academy." Now we know what Khan really did after leaving Ceti Alpha 5...)
