John Allen Paulos

John Allen Paulos (born July 4, 1945) is an American professor of mathematics at Temple University in Philadelphia, Pennsylvania. He has gained fame as a writer and speaker on mathematics and the importance of mathematical literacy. Paulos writes about many subjects, especially of the dangers of mathematical innumeracy; that is, the layperson's misconceptions about numbers, probability, and logic.

Paulos was born in Denver, Colorado and grew up in Chicago, Illinois and Milwaukee, Wisconsin, where he attended high school. After his Bachelor of Mathematics at University of Wisconsin (1967) and his Master of Science at University of Washington (1968), he received his PhD in mathematics from the University of Wisconsin–Madison (1974). In an interview he described himself as lifelong skeptic. He volunteered for the Peace Corps in the seventies.

Mathematics is no more computation than literature is typing.

The most amazing coincidence of all would be the complete absence of all coincidences.

Uncertainty is the only certainty there is, and knowing how to live with insecurity is the only security.

His academic work is mainly in mathematical logic and probability theory.

His book Innumeracy: Mathematical Illiteracy and its Consequences (1988) was a bestseller and A Mathematician Reads the Newspaper (1995) extended the critique. In his books Paulos discusses innumeracy with quirky anecdotes, scenarios and facts, encouraging readers in the end to look at their world in a more quantitative way.

He has also written on other subjects often "combining disparate disciplines", such as the mathematical and philosophical basis of humor in Mathematics and Humor and I Think, Therefore I Laugh, the stock market in A Mathematician Plays the Stock Market, quantitative aspects of narrative in Once Upon a Number, the arguments for God in Irreligion, and most recently "bringing mathematics to bear on...biography" in A Numerate Life.
