Persi Diaconis at Stanford (Summer 2004). Persi Warren Diaconis (born January 31, 1945) is an American mathematician and former professional magician. He is Mary V. Sunseri professor of statistics and professor of mathematics at Stanford University. He is particularly known for tackling mathematical problems involving randomness and randomization, such as coin flipping and shuffling playing cards.

Professor Diaconis achieved brief national fame when he received a MacArthur Fellowship in 1979, and again in 1992 after the publication (with D. Bayer) of a paper entitled "Trailing the Dovetail Shuffle to its Lair" (a term coined by magician Charles Jordan in the early 1900s) which established rigorous results on how many times a deck of playing cards must be shuffled before it can be considered "random enough." Diaconis established that the deck gradually increases in randomness until seven shuffles, after which the thus-far experienced increase in randomness with each shuffle decreases sharply. Seven shuffles, for reasons made precise in the paper, is what casinos should use. The John D. and Catherine T. MacArthur Foundation is a private, independent grantmaking institution. ...
Biography trivia
Diaconis is a colorful character. He left home at 14 [1] to travel with sleight-of-hand legend Dai Vernon, and dropped out of high school, promising himself that he would return one day so that he learn all of the math necessary to read William Feller's famous two-volume treatise on probability theory, entitled An Introduction To Probability Theory and its Applications. He returned to school, learned Feller, and became a great mathematical probabilist. Sleight of hand, also known as prestidigitation (quick fingers) or legerdemain (pronounced in French, from lightness of hand or deformation of le jeu de main i. ...
