A few days ago I posted about the computational engine Wolfram Alpha and received a couple of comments saying that the engine was not so easy to use. The engine is very powerful and was voted the greatest computer innovation of 2009 by Popular Science, but the commenters were right. It is not as intuitive as other engines. Here then is a video produced by none other than Stephen Wolfram himself showing you how to use it and showcasing its power. Check it out. It really is a great resource.
