Ha!

In 1722, Jonathan Swift published the “last speech” of one Ebenezer Elliston, “a malefactor executed for street robbery,” “published at his desire for the common good”:

Now as I am a dying man I have done something which may be of good use to the public. I have left with an honest man (and, indeed, the only honest man I was ever acquainted with) the names of all my wicked brethren, the present places of their abode, with a short account of the chief crimes they have committed, in many of which I have been their accomplice, and heard the rest from their own mouths: I have likewise set down the names of those we call our setters, of the wicked houses we frequent, and of those who receive and buy our stolen goods. I have solemnly charged this honest man and have received his promise upon oath, that whenever he hears of any rogue to be tried for robbing or housebreaking, he will look into his list, and if he finds the name there of the thief concerned, to send the whole paper to the government. Of this I here give my companions fair and public warning, and hope they will take it.

Did it work? Who knows?

Mouthful

In 1641, a syndicate of Puritan clergymen published a pamphlet upholding the Presbyterian theory of the ministry.

They published it under the memorable pseudonym Smectymnuus, an acronym derived from the initials of the five authors: Stephen Marshall, Edmund Calamy, Thomas Young, Matthew Newcomen, and William Spurstowe.

The Oxford English Dictionary still recognizes the wonderful word Smectymnuan, meaning any of these authors or one who accepted their views.

Paper Route

Origami can solve general cubic equations! The method was developed by Italian mathematician Margherita Piazzolla Beloch, who in 1936 found a way to use paper folding to construct the common tangents to two parabolas.

Given two points p1 and p2 and two lines l1 and l2, we can, whenever possible, make a single fold (dashed line) that puts p1 onto l1 and p2 onto l2 simultaneously. This fold finds a common tangent to two parabolas: one with focus p1 and directrix l1, the other with focus p2 and directrix l2.

“Now, two parabolas drawn in the plane can have at most three different common tangents, suggesting that this origami fold is equivalent to solving a cubic equation,” writes Western New England College mathematician Thomas C. Hull. “Straightedge and compass constructions, on the other hand, can only solve general quadratic equations.”

Beloch’s contribution went uncredited for decades, but it’s now receiving a fuller appreciation. See the 2011 paper below for more details.

The Social Whirl

In a 1962 nightmare, writer Thomas Meehan imagined having to introduce Uta Hagen to Yma Sumac, Ava Gardner, Abba Eban, Oona O’Neill, Ugo Betti, Ona Munson, Ida Lupino, the Aga Khan, Ira Wolfert, Ilya Ehrenburg, and Eva Gabor at a Greenwich Village cocktail party:

“Uta, Yma; Uta, Ava; Uta, Oona; Uta, Ona; Uta, Ida; Uta, Ugo; Uta, Abba; Uta, Ilya; Uta, Ira; Uta, Aga; Uta, Eva.”

Then Polish concert pianist Mieczyslaw Horszowski turns up. “‘Come in, Mieczyslaw!’ I cry, with tears in my eyes. ‘I’ve never been so glad to see anyone in my whole life!'”

Before and After

Why does the slogan ‘Whatever is, always was to be’ seem to imply that nothing can be helped, where the obverse slogan ‘Whatever is, will always have been’ does not seem to imply this? We are not exercised by the notorious fact that when the horse has already escaped it is too late to shut the stable door. We are sometimes exercised by the idea that as the horse is either going to escape or not going to escape, to shut the stable door beforehand is either unavailing or unnecessary.

— Gilbert Ryle, Dilemmas, 1954

Long Distance

The Javan cucumber, Alsomitra macrocarpa, broadcasts its seeds on papery wings that can glide long distances. Some have been found on the decks of ships.

The unique design inspired aviation pioneer Igo Etrich to build an artificial flying wing, which he adapted into Germany’s first mass-produced military aeroplane.

The Watercolor Illusion

The interior of this map is white, but it appears to be suffused with a pale yellow. In fact the blue and orange coloring is confined to the border.

This “bleeding” effect was discovered by University of Sassari psychologist Baingio Pinna in 1987. It’s still being investigated.

“A Dimensional Howler”

The 1961 GCE O-level exam included this question:

If one square yard of material costs 18 pence, what is the price of one square foot?

One student considered:

1 square yard costs 18 pence.

Therefore 1 yard costs  \sqrt{18} , or 4.243, pence.

Therefore 1 foot costs 4.243 ÷ 3 = 1.414 pence.

Therefore 1 square foot costs 1.4142 = 2 pence.

(Via Eureka.)

05/26/2026 UPDATE: Reader Catalin Voinescu adds:

For more dimensional fun, check out ‘ohms per square’ (symbol: capital omega divided by a literal square). The resistance of sheet material depends only on the shape of the object, not on the scale (assuming the thickness of the sheet stays the same). Any square of a given material, of any size, has the same resistance when measured between opposite edges. Longer, narrower shapes have higher resistance, and shorter, wider ones have lower resistance, but only the aspect ratio matters, not the actual dimensions. So the resistivity of conductive sheet is expressed as the resistance of a square piece of that material: ohms per square. This unit is used in electrical engineering, where thin conductive layers and foils are common, most obviously in PCB manufacturing, but also in the manufacturing of resistors, capacitors, semiconductors, batteries and solar panels.

(Thanks, Catalin.)

Riding Along

A striking observation in Far From the Madding Crowd:

To persons standing alone on a hill during a clear midnight such as this, the roll of the world eastward is almost a palpable movement. The sensation may be caused by the panoramic glide of the stars past earthly objects, which is perceptible in a few minutes of stillness, or by the better outlook upon space that a hill affords, or by the wind, or by the solitude; but whatever be its origin, the impression of riding along is vivid and abiding. The poetry of motion is a phrase much in use, and to enjoy the epic form of that gratification it is necessary to stand on a hill at a small hour of the night, and, having first expanded with a sense of difference from the mass of civilised mankind, who are dreamwrapt and disregardful of all such proceedings at this time, long and quietly watch your stately progress through the stars.

“After such a nocturnal reconnoitre it is hard to get back to earth, and to believe that the consciousness of such majestic speeding is derived from a tiny human frame.”
