Imagine if you could go online and find a math, science or economics tutor that could help you get your daughter through a high school trig equation or your son to master a college finance course. Envisage also that this would be presented in a clear, concise and even entertaining manner. Naturally it would be free of charge.
Well, folks, look no more. Welcome to the Khan Academy.
Working out of his home in Silicon Valley, Salman Khan, a former hedge fund analyst, could be transforming the way people all over the world will learn math and other subjects.
Khan, an MIT math and science grad with an MBA from Harvard, was doing very well at his employer's hedge fund but got hooked on education after he helped one of his cousins, a seventh-grader who was having trouble with math.
He tutored her online with a blackboard on the screen. That led him to eventually place math lessons on YouTube. It didn't take long before he was a worldwide phenomenon. (See www.youtube.com/watch?v=po3DAsr6mDE)
