The world's factual knowledge is now computable and accessible to you. You may not have been staying up nights worrying about comparing historical weather patterns or conjuring graphs to improve your household energy usage, but this is very cool. Different from a search engine, the computational knowledge engine draws from a huge collection of original data sources, not just other web sites. It also performs numerical calculations.

So, go ahead and try the newly launched Wolfram Alpha. Enter the names of two cities to get a comparison of the populations, the distance in miles between them and the time it takes to fly from one to the other. Enter your choice of a food, for the nutrition facts, calories, fat content and more. Did you know a poached egg only has 50 calories? Try something challenging.

The introduction by its creator, mathematician, scientist and software entrepreneur Stephen Wolfram is fun and helpful as a launching point.
