Created by Dr. Mads Haahr of the School of Computer Sciences and Statistics at Trinity College, Dublin, RANDOM.ORG has generated over two trillion truly random bits in its nearly two decade history. As the site notes, "true" randomness is not as easy to come by as one might think. In fact, most computers generate pseudo-random numbers using mathematical formulae. RANDOM.ORG, on the other hand, uses atmospheric noise to generate truly random numbers for anything from lottery drawings to coin flips to card shuffles. Many of the services on the website are free, though readers may also use the Third-Party Draw Service for a small fee. Readers may also like to explore the Learn About Randomness section, where they can learn about the history of randomness, read testimonials, and peruse quotations.
