Hey - the internet isn't only for voyeurs and narcissists and videos of monkeys washing cats!
The Khan Academy is a non-profit, web-based grassroots initiative founded by MIT graduate Sal Khan. The Khan Academy's mission is to educate the masses, free of charge, on just about any topic you can think of, from simple arithmetic to chemistry and much more, all delivered in short, easy to follow YouTube videos.
It all started as a series of short videos posted to the internet to help tutor his cousins, and has now grown to an video library with more than 2300 short films which has served up more than 58 million videos to date. A non-profit organization, the Khan Academy has received funding from both the Bill and Melinda Gates Foundation and Google.
I have viewed a couple of these videos (cough) simple math (cough) and they are quite well done. they're not heavy, not too long, and there are a lot of pictures (suits me well)!
I wanted to share because it seems like a good place to pick up some extra smarts, if you or someone you know happens to need them.
