What It Takes

This article began as a parenthesis to a planned article (yet to be completed) about passion and reason, as related by David Hume, according to whom,

Reason is, and ought only to be[,] the slave of the passions, and can never pretend to any other office than to serve and obey them.

I thought about how I had not really read Hume since college; I thought more about what did not end up in my previous article here; it seemed I was working out another article, the present one, which ends up considering arguments that natural science is founded on the Christian creed, and takes note along the way of continuing censorship of Wikipedia by the Turkish state.

Effectiveness

I am writing from the Math Village, and here I happen to have read that Abraham Lincoln kept no known diary as such, but noted his thoughts on loose slips of paper. Admired because he “could simply sit down and write another of his eloquent public letters,”

Lincoln demurred. “I had it nearly all in there,” he said, pointing to an open desk drawer. “It was in disconnected thoughts, which I had jotted down from time to time on separate scraps of paper.” This was how he worked, the president explained. It was on such scraps of paper, accumulating over the years into a diaristic density, that Lincoln saved and assembled what he described to the visitor as his “best thoughts on the subject.”

Thus Ronald C. White, “Notes to Self,” Harper’s, February 2018. My own notes to self are normally in bound notebooks, and perhaps later in blog articles such as the present one, which is inspired by the 1960 article called “The Unreasonable Effectiveness of Mathematics in the Natural Sciences,” by Eugene Wigner.

Boolean Arithmetic

Mathematics can be highly abstract, though remaining applicable to daily life. I want to show this with the mathematics behind logic puzzles, such as how to derive a conclusion using all of the following premisses:

  1. Babies are illogical.
  2. Nobody is despised who can manage a crocodile.
  3. Illogical persons are despised.

The example, from Terence Tao’s blog, is attributed to Lewis Carroll. By the first and third premisses, babies are despised; by the second premiss then, babies cannot manage crocodiles.

The Tree of Life

My two recent courses at the Nesin Mathematics Village had a common theme. I want to describe the theme here, as simply as I can—I mean, by using as little technical knowledge of mathematics as I can. But I shall talk also about related poetry and philosophy, of T. S. Eliot and R. G. Collingwood respectively.

Şirince January 2018

In the Nesin Mathematics Village recently, I was joined at breakfast one morning by a journalist called Jérémie Berlioux. He knew Clément Girardot, the journalist whom I had met in the Village in the summer of 2016. This was before the coup attempt of July 15, but after the terror attack at Atatürk Airport on June 28. I wrote about this attack the next day in “Life in Wartime” on this blog. Then I headed off to Şirince to join a “research group.” My wife and colleague came along, though not to be part of the group; afterwards we headed up the coast for a beach holiday. We were at the beach when the coup attempt happened, as I wrote in my next blog article, “War Continues.” I contrasted politics with mathematics, which was an inherently nonviolent struggle. This was the kind of struggle engaged in by the research group in the Math Village.

Women and Men

This began as an update to “Confessions,” which concerns the man called G. H. Hardy and the woman called Sylvia Plath. I had originally included a photograph of the subjects’ respective books. On Hardy’s, the author poses reluctantly; on Plath’s, a woman applies powder in a compact mirror.

Plath’s book was the 2013 Faber and Faber 50th Anniversary Edition of The Bell Jar, and the cover is controversial. See Alexandra Topping, “The Bell Jar’s new cover derided for branding Sylvia Plath novel as chick lit” (The Guardian, Friday 1 February 2013). I learned of the controversy from Emily Van Duyne, “Sylvia Plath Looked Good in a Bikini—Deal With It,” in Electric Literature, hosted by Medium (October 9, 2017). Medium had promoted the essay to me when I read Brian E. Denton, “The World Will Not Quarrel: Day 282 of A Year of War and Peace.

Hypomnesis

When is a help a hindrance? The Muses have provoked this question. They did this through their agents, the cicadas, who sang around the European Cultural Center of Delphi, during the 11th Panhellenic Logic Symposium, July 12–5, 2017.

Tophane-i Amire, 2017.03.25

Last week I wrote about the Turkish Impressionist Feyhaman Duran, born in 1886. Now my subject is the Hungarian-French Op Artist born twenty years later as Győző Vásárhelyi. His “Rétrospective en Turquie” is at the Tophane-i Amire Culture and Art Center in an Ottoman cannon foundry.

Şirince January 2017

Having enjoyed spending a January week at the Nesin Mathematics Village in 2016, this year I came back for two weeks. My spouse will join me for the second week. Meanwhile, here are some photographs from this amazing place. Continue reading

Confessions

This is about G. H. Hardy and Sylvia Plath: Hardy quâ author of A Mathematician’s Apology (1940); Plath, The Bell Jar (1963).

I first read Plath only recently, after encountering The Bell Jar by chance in the Istanbul bookshop called Pandora. Continue reading
