This week, I found a not-for-profit organization called Khan Academy. Khan Academy was created by American entrepreneur, Salman Khan. His mission is to use YouTube technology to provide "a high quality education to anyone, anywhere." Sal has recorded twenty 8-to-10-minute YouTube demonstrations of basic arithmetic, and also hundreds of lessons on many higher-level concepts in mathematics, physics, finance, and entrepreneurship for high school aged kids and adults. Sal is a gifted teacher, and even if you haven't found science to be your cup of tea, you'll find yourself engaged. It's a quick way to learn a LOT about physical science, math, economics, and the like--both for kids and for adults.
