It’s not much past 9 a.m., and Khan, 36, founder of the online educational non-profit Khan Academy, gets set to record his 3,081st video lecture in a small office with a view of air conditioning ducts.
“In 1997, you see, there was a devaluation of the Thai currency,” Khan says into a beefy microphone as he makes crude sketches on his monitor.
If you want gleaming high-tech, go down the road to Google’s campus. If you’re looking for a revolution, this is the right address.
Ever since quitting his job as a successful hedge-fund analyst two years ago to dedicate himself full time to this labor of love, Khan has managed to win fans worldwide and goad skeptical educators.
