Khan Academy: Math & Science Lessons Online

Spencer Michels:

33-year-old math and science whiz kid -- working out of his house in California's Silicon Valley -- may be revolutionizing how people all over the world will learn math. He is Salman Khan, and until a few months ago he made his living as a hedge fund analyst. But he's become a kind of an unseen rock star in the online instruction field, posting 1200 lessons in math and science on YouTube, none of them lasting more than about 10 minutes. He quit his job at the hedge fund to devote full time to his Khan Academy teaching efforts, which he does essentially for free.

Khan explained how the U.S. unemployment rate is calculated in a NewsHour exclusive video.
