John Allen Paulos is a mathematics professor at Temple University and the author of many books, including Innumeracy, A Mathematician Reads the Newspaper, and, most recently, A Numerate Life.
by John Allen Paulos Kurt Gödel was a logician whose work in mathematical logic was seminal and fundamental. His famous incompleteness theorems, in particular, have changed our view of mathematics and computer science. He was born in Austria and lived through political turmoil there before fleeing the country after the Nazis annexed it in 1938.…
by John Allen Paulos Raymond Queneau was a French novelist, poet, mathematician, and co-founder of the Oulipo group about which I wrote last year here. The group is primarily composed of French writers, mathematicians, and academics and explores the use of mathematical and quasi-mathematical techniques in literature. Their work is funny, experimental, weird, and thought-provoking. A reader of…
by John Allen Paulos Despite many people’s apocalyptic response to ChatGPT, a great deal of caution and skepticism is in order. Some of it is philosophical, some of it practical and social. Let me begin with the former. Whatever its usefulness, we naturally wonder whether CharGPT and its near relatives understand language and, more generally,…
by John Allen Paulos Intelligibility or precision: to combine the two is impossible. ―Bertrand Russell. Please forgive the long letter; I didn’t have time to write a short one. ―Blaise Pascal I have always resonated with the two quotes above and believe they’re particularly germane to writing popular mathematics. Let me start with Russell. If his…
by John Allen Paulos Numerology can easily result from free association and, given its assertions, it certainly seems like it has been. In any case, I thought I’d try my hand at it. In particular, the date 9-11 and the destruction of the WTC twin towers have together given rise to all sorts of numerological…
by John Allen Paulos I recall a party game I once wrote about. The game, described by philosopher Daniel C. Dennett in his book “Consciousness Explained,” is a variant of the familiar childhood game requiring that one try to determine by means of Yes or No questions a secretly chosen number between one and one…
by John Allen Paulos Herschel Walker claims that we have enough trees already, that we send China our clean air and they return their dirty air to us, that evolution makes no sense since there are still apes around, and freely offers other astute scientific insights. He may be among the least knowledgeable (to put…
by John Allen Paulos The separation of church and state seems to be dissolving. It’s becoming increasingly easy for politicians and other public figures to cross the line between expressing their faith and aggressively proclaiming it and its alleged real-world consequences. Although often leading to social strife and intolerance, such overweening proclamations are growing in…
by John Allen Paulos Lanchester’s square law was formulated during World War I and has been taught in the military ever since. It is marginally relevant to the war in Ukraine, particularly the balance between the quantity and quality of the two armies’ weapon systems. Although more accurately expressed in terms of differential equations, Lanchester’s…
by John Allen Paulos The Ouvroir de Littérature Potentielle (Workshop of Potential Literature), Oulipo for short, is the name of a group of primarily French writers, mathematicians, and academics that explores the use of mathematical and quasi-mathematical techniques in literature. Don’t let this description scare you. The results are often amusing, strange, and thought-provoking. The…
by John Allen Paulos Covid has given rise to a variety of counterintuitive mathematical outcomes. A good example is this recent headline (link below): One third of those hospitalized in Massachusetts are vaccinated. Anti-vaxxers have seized on this and similar such factually accurate headlines to bolster their positions. They, and others as well, interpret them…
by John Allen Paulos In politics, business, and education, the issue of how to ensure proportional representation of groups is often salient. A salient issue, but usually an impossible task. Why? Since group identity and wokeness arouse so much emotion, a “geologic upheaval of thought” as Proust characterized it, it’s probably best to discuss a…
by John Allen Paulos The well-known counterintuitive Monty Hall problem continues to baffle people if the emails I receive are any indication. A meta-problem is to understand why so many people are unconvinced by the various solutions. Sometimes people even cite the large number of the unconvinced as proof that the solution is a matter…
by John Allen Paulos I’ve always liked stories that depended on mistaken identity, a very old theme in general. Having a degree in mathematical logic, I was also drawn to the subject on a more theoretical level, on which lies Gettier’s Paradox. Since Plato and the ancient Greeks, knowledge has been taken by many philosophers…
In honor of Valentine’s Day, John Allen Paulos has sent us the following expanded excerpt from his new book Irreligion: A Mathematician Explains Why the Arguments for God Just Don’t Add Up: I found myself at loose ends in a beach town in Thailand on Christmas morning, 2006. Away from my family in Philadelphia, I…
by John Allen Paulos What can I say or recall about 9/11 that hasn’t been said or recalled at least 911 times? Not much. Despite the incessant and synecdochic repetition of 9/11, 9/11, 9/11 (or maybe because of it), I find it very hard to project myself back into the state of mind I had…
