WolframAlpha's computational engine lets you take trillions of
pieces of data and "mash up topic areas such as people,
finance, dates, and more to do impressive, if not outrageous,
computations." Create and share "fun facts" such as

The word love is the 557th most commonly spoken word

You would need to go 311.2684 miles per day to travel the world in 80 days

It would require 8.4×10^{11} gallons of paint to cover the surface of the moon

If driving a car at 60 miles per hour, it will take 11.18
million years to travel one light year

The average American consumes 125.6 lbs of potatoes per year
Wolfram recently started a Twitter feed for all of the fun
facts that they, and you, discover every day. Follow
