This is mind-blowing. Khan Academy is a collection of over 2,400 education tutorials in the form of YouTube videos. One man started making these videos to tutor his young relatives, and has persisted to a remarkable extent. I am absolutely addicted to these things. He covers concepts from elementary school through college, on an amazing range of subjects, with incredible intuitive clarity. You have to watch one of these things to see the simple magic of it.

What does it mean when any child in the world with motivation, an Internet connection, and an understanding of English can be better-educated that many (most?) high school graduates, for free? Each of his lessons has been viewed over 30,000 times on average. What does it mean when this man (Sal Khan) who isn’t even a certified teacher is now teaching more students than anyone else in the world? What does it mean when dynamic sight-and-sound video is free and textbooks still cost a lot? And what does this say about the power of remarkable diligence and persistence?

All of this is made possible by the Internet. The changes the Internet is bringing to our world are just beginning.

My mind is so blown, I think I have to try it for myself. Watch for a Khan-style video in place of my next blog post. He made 2,400 in a row, let’s see if I can make 1.
