Persi Warren Diaconis (born January 31, 1945) is an American mathematician and former professional magician. Events 1504 - France cedes Naples to Aragon. 1606 - Gunpowder Plot: Guy Fawkes Year 1945 ( MCMXLV) was a Common year starting on Monday (link will display the full calendar The United States of America —commonly referred to as the A mathematician is a person whose primary area of study and research is the field of Mathematics. He is the Mary V.  Sunseri Professor of Statistics and Mathematics at Stanford University. Statistics is a mathematical science pertaining to the collection analysis interpretation or explanation and presentation of Data. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Leland Stanford Junior University, commonly known as Stanford University or simply Stanford, is a private Research university located in He is particularly known for tackling mathematical problems involving randomness and randomization, such as coin flipping and shuffling playing cards. Randomness is a lack of order Purpose, cause, or predictability Randomization is the process of making something Random; this means Generating a Random permutation of a sequence (such as when shuffling cards Coin flipping or coin tossing is the practice of throwing a Coin in the air to resolve a Dispute between two parties or otherwise choose between two alternatives Shuffling is a procedure used to randomize a deck of Playing cards to provide an element of chance in Card games Shuffling is often followed by a

Professor Diaconis achieved brief national fame when he received a MacArthur Fellowship in 1979, and again in 1992 after the publication (with Dave 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 52 playing cards must be riffle shuffled before it can be considered "random enough. The John D and Catherine T MacArthur Foundation is a major private grant -making Private foundation based in Chicago that has awarded more than US$4 billion Dave Bayer is an American Mathematician. He is currently a Professor of Mathematics at Barnard College, Columbia University Shuffling is a procedure used to randomize a deck of Playing cards to provide an element of chance in Card games Shuffling is often followed by a " Diaconis established that the deck gradually increases in randomness until seven shuffles, after which the thus-far experienced increase in randomness stops significantly increasing. At least seven shuffles, for reasons made precise in the paper, is what casinos should use.

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 could 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. Sleight of hand, also known as prestidigitation ("quick fingers" or léger de main (from the French for "lightness of hand" Dai Vernon (June 11 1894 &ndash August 21 1992 was a Canadian magician. William (Vilim Feller né Vilibald Srećko Feller ( July 7 1906 &ndash January 14 1970) was a Croatian American He returned to school, learned Feller, and became a great mathematical probabilist.
