Wolfram Fun Facts


Wolfram|Alpha'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 8.4×1011 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 @WolframFunFacts and tweet your favorites to #funfact
