Salman Khan used to be an analyst at a hedge fund. Until his cousins asked him to help with a homework assignment. He posted a video on YouTube for them watch. Not only did they see it, but others did, as well.
From there, the Khan Academy began and has since grown to a website of videos on math and, recently, other subjects. It has continued to grow in popularity and even caught the eye of Bill Gates.
Watch Salman's intriguing TED Talk and see how his videos are 'flipping the classroom.' Who knows, this might be the start of a revolutionary form of teaching and learning with the help of technology.
