Nature, Nurture

Identical twins Jack Yufe and Oskar Stohr were born in 1932 to a Jewish father and a Catholic mother. Their parents divorced when the boys were six months old; Oskar was raised by his grandmother in Czechoslovakia, where he learned to love Hitler and hate Jews, and Jack was raised in Trinidad by his father, who taught him loyalty to the Jews and hatred of Hitler.

At 47 they were reunited by scientists at the University of Minnesota. Oskar was a conservative who enjoyed leisure, Jack a liberal workaholic. But both read magazines from back to front, both wore tight bathing suits, both wrapped rubber bands around their wrists, both liked sweet liqueur and spicy foods, both had difficulty with math, both flushed the toilet before and after using it — and both enjoyed sneezing suddenly in elevators to startle other passengers.

“Imitation”

Calm and implacable,
Eyeing disdainfully the world beneath,
Sat Humpty-Dumpty on his mural eminence
In solemn state:
And I relate his story
In verse unfettered by the bothering restrictions of rhyme or metre,
In verse (or “rhythm,” as I prefer to call it)
Which, consequently, is far from difficult to write.

He sat. And at his feet
The world passed on — the surging crowd
Of men and women, passionate, turgid, dense,
Keenly alert, lethargic, or obese.
(Those two lines scan!)

Among the rest
He noted Jones; Jones with his Roman nose,
His eyebrows — the left one streaked with a dash of gray –
And yellow boots.
Not that Jones
Has anything in particular to do with the story;
But a descriptive phrase
Like the above shows that the writer is
A Master of Realism.

Let us proceed. Suddenly from his seat
Did Humpty-Dumpty slip. Vainly he clutched
The impalpable air. Down and down,
Right to the foot of the wall,
Right on to the horribly hard pavement that ran beneath it,
Humpty-Dumpty, the unfortunate Humpty-Dumpty,
Fell.

And him, alas! no equine agency,
Him no power of regal battalions –
Resourceful, eager, strenuous –
Could ever restore to the lofty eminence
Which once was his.
Still he lies on the very identical
Spot where he fell — lies, as I said, on the ground,
Shamefully and conspicuously abased!

– Anthony C. Deane, in Carolyn Wells, A Parody Anthology, 1922

A Natural Seat

http://en.wikipedia.org/wiki/File:Krubsack_chair.jpg

John Krubsack grew a chair. The Wisconsin banker planted 32 box elders in 1903, and as they grew he grafted them into a living piece of furniture.

In 1911 he began lending “The Chair That Grew” to international exhibitions; today it’s on display at his nephew’s furniture store.

Hendecadivisibility

To discover whether a number is divisible by 11, add the digits that appear in odd positions (first, third, and so on), and separately add the digits in even positions. If the difference between these two sums is evenly divisible by 11, then so is the original number. Otherwise it’s not.

For example:

11 × 198249381729 = 2180743199019

Sum of digits in odd positions = 2 + 8 + 7 + 3 + 9 + 0 + 9 = 38

Sum of digits in even positions = 1 + 0 + 4 + 1 + 9 + 1 = 16

38 – 16 = 22

22 is a multiple of 11, so 2180743199019 is as well.

Fair Enough

A lady wrote to her lover, begging him to send her some money. She added, by way of postcript, ‘I am so ashamed of the request I have made in this letter, that I sent after the postman to get it back; but the servant could not overtake him.’

Fugitive Truth

When I conduct a psychological experiment, my expectations might influence the outcome.

That’s called the experimenter expectancy effect. Does it exist? Well, we could do an experiment to detect it …

… but if it exists then it would bias the experiment, and if it doesn’t then we’d detect nothing. Either way, it seems, we can’t reliably assess what’s happening.
