There are many ways to obtain information and learn something about a new subject online. We can start on Wikipedia for an overview and then, when possible, follow the refrences and eternal links to find further information. And, this method is fine for some things, but a piecemeal approach is not always necessary or desirable. There is a place to go when you want specific information about several subjects, including, mathematics, history, finance, physics, chemistry, astronomy, economics, and computer science with more to follow.
Khan Academy is a repository of over 2400 videos covering the above mentioned subjects. It was started in 2006, went full time in 2009, and is currently operated by the founder, Salman Khan, a man with a mission and three degrees from MIT, and a Harvard MBA. The mission: "Provide a high quality education to anyone, anywhere". Khan Academy is a not for profit organization, funded by donations and some ad revenue, and operates under a Creative Commons license. This is really open source education at its best. Google recently pledged 2 Million dollars to expand and enrich the content.
I first read an interview with Salman Khan n 2009, and he was talking about education in the K through 12 time period. His observation was that in each grade there are some students who operate at 90% and some at 70%. Yet at the end of the year, both move on to the next grade with some "gaps" in their learning. It seems that we all have some gaps in our learning and it is helpful to review and learn new material as well. I really think that Khan Academy is a good place to visit and learn. You can get a great idea of what the site offers by scrolling down to the first section, algebra, simple equations to see how this teaching repository works in a conversational and engaging way.
