Riddles

From a collection in Frank Mittler’s Little Book of Word Tricks (1958):

1. Pray tell me, listener, if you can,
Who is that highly-favored man
Who, though he marries many a wife,
May still stay single all his life?

2. I sit in fire, but not in the flame;
I follow the master, but not the dame;
I’m found in the church, but not in the steeple;
I belong to the monarch, but not the people.

3. Its light was mellow, soft and lazy;
One foot broke off — and it went crazy!

4. What is found in the very center of both America and Australia?

5. What divides by uniting and unites by dividing?

6. Why is a popular crooner like a doctor in an asylum?

When electricity first became widely available, it was hailed as marvel, more valuable even than a human servant. In a 1914 manual on using electricity in the home, Maud Lancaster wrote:

[I]t is always at hand; always willing to do its allotted task and do it perfectly silently, swiftly and without mess; never wants a day off, never answers back, is never laid up, never asks for a rise; in fact it is often willing to work for less money; never gives notice and does not mind working overtime; it has no prejudices and is prepared to undertake any duties for which it is adapted; it costs nothing when it is not actually doing useful work.

First, though, people had to learn to use it. In 1884, electrical engineer Rookes Crompton wrote, “At the recent Crystal Palace Electrical Exhibition, a couple from the country asked the price of an incandescent lamp at one of the stalls, and being supplied with it for 5s., expended a box of matches in trying to light it, and then declared the whole thing was a swindle.”

No Comment

In 1958, momentarily exasperated at the jargon that afflicted behavioral science, Harvard sociologist Daniel Bell typed up an impenetrable paper titled “The Parameters of Social Movements: A Formal Paradigm”:

The purpose of this scheme is to present a taxonomic dichotomization which would allow for unilinear comparisons. In this fashion we could hope to distinguish the relevant variables which determine the functional specificities of social movements. Any classificatory scheme is, essentially, an answer to some implicit other scheme. In this instance, it is an attempt to answer the various hylozoic theories which deny that social categories can be separable.

He divided social movements into two types, the homologous and the metonymous. Homologous movements are distinguished by structural variables (monocotyledonous and dicotyledonous), matrix variables (ultramontane and anti-nomian), and process variables (syncretistic and diastrophic). Metonymous movements, by contrast, are marked by goal definitions (transcendental or eschatological), a matrix of change that’s quietistic or chiliastic (the latter either sectarian or lacrimatarian), and a mode of change that’s immanent or informed by kairos (diastasis).

“I sent it off to two sociological friends, who I thought would appreciate it, and one sent me back a serious letter about some of the categories, while the other, not knowing whether it was a spoof or not, wrote: ‘You are too good a sociologist not to have created something which itself is quite useful.'”

(From Dwight Macdonald, Parodies, 1960.)

Landscapes

Alexandra Kehayoglou makes carpets that evoke the topography of her native Argentina: grasslands, waterways, and glaciers. Her family opened a conventional carpet company there in 1956, and she discovered she could use scraps from their work to create “tactile canvases.” Each piece is composed by hand from discarded or surplus wool on a vertical frame, using a tufting gun and carpet scissors.

Her work often draws attention to natural areas altered by human activity in Argentina, such as the Raggio Creek north of Buenos Aires, destroyed for a shopping mall, or the Santa Cruz River, the last free-flowing wild river in the country, proposed site of two major hydroelectricity dams.

“It’s hard for people to understand that a rug can be art,” she told the New York Times. “But maybe that’s changing.”

Chessametics

keith chessametic

Mike Keith published this remarkable invention in the Journal of Recreational Mathematics in 1975. Suppose a chess game goes:

P-K4   P-K4 
B-B4   P-R4 
Q-B3   P-R4 
QxP

This is checkmate, so White says “I win!” Now if the game score is written out in one column, including White’s exclamation:

P-K4
P-K4
B-B4
P-R4
Q-B3
P-R4
 QxP
----
IWIN

… we get a solvable alphametic — replace each letter (and the symbols x and -) with a unique digit and you get a valid sum. (The digits already shown count as numbers, and those numbers also remain available to replace letters.)

This example isn’t quite perfect — the two moves P-R4 are ambiguous, as is the final pawn capture. Keith’s Alphametics Page has an even better specimen, a pretty variation from a real 1912 game by Siegbert Tarrasch. It’s 13 moves long and forms a perfect alphametic with a unique solution.

https://en.wikipedia.org/wiki/File:Front_page_of_Conlon_Nancarrow%27s_Study_for_Player_Piano_No._41.jpg

Because he wrote for player pianos, Conlon Nancarrow could demand more exacting performances than other composers. His Study No. 41 is in three parts for two pianos. The first canon has a time signature of \frac{1}{\sqrt{\pi}} / \sqrt{2/3} for the first piano; the second is in \frac{1}{3 \sqrt{\pi}} / \sqrt[3]{13/16} for the second piano; and the third is in \frac{\frac{1}{3 \sqrt{\pi}} / \sqrt[3]{13/16}}{\frac{1}{\sqrt{\pi}} / \sqrt{2/3}} for both pianos. In the third part, the two performances must be played in proportions marked in a diagram in the score (above). It sounds like this:

Podcast Episode 244: The Women’s Protest

In February 1943, hundreds of German women joined in a spontaneous protest in central Berlin. They were objecting to the roundup of some of the city’s last Jews — their husbands. In this week’s episode of the Futility Closet podcast we’ll describe the Rosenstrasse protest, a remarkable example of civil disobedience.

We’ll also ponder whether a computer can make art and puzzle over some unusual phone calls.

Double Vision

French street artist JR has twice transformed I.M. Pei’s iconic pyramid at the Musée du Louvre in Paris.

In 2016 he made it disappear by overlaying one face with an image of the background facade.

And just this month (below) he applied 2,000 stickers to the surrounding pavement to create an anamorphic illusion in which the pyramid seems to rise from a crater.

The paper stickers were quickly destroyed by wandering tourists, but that was expected, he said. “The images, like life, are ephemeral. Once pasted, the art piece lives on its own. The sun dries the light glue and with every step, people tear pieces of the fragile paper. The process is all about participation of volunteers, visitors, and souvenir catchers.”
