Giuseppe PeanoDied 20 Apr 1932 at age 73 (born 27 Aug 1858). Italian mathematician who founded symbolic logic. Through the use of symbols, equations are more easily understood by anyone regardless of their language. For example, Peano introduced symbols to represent “belongs to the set of” and “there exists.” In Arithmetics principia (1889), a pamphlet he wrote in Latin, Peano published his first version of a system of mathematical logic, giving his Peano axioms defining the natural numbers in terms of sets. In 1903, Peano unsuccessfully proposed an international, artificial language he called “Latino sine flexione.” It was based on Latin without grammar. Its vocabulary comprised words from English, French, German and Latin.« |
