Turbulence

The roots of the word helicopter are not heli and copter but helico and pter, from the Greek “helix” (spiral) and “pteron” (wing).

G.L.M. de Ponton’s 1861 British patent says, “The required ascensional motion is given to my aerostatical apparatus (which I intend denominating aeronef or helicoptere,) by means of two or more superposed horizontal helixes combined together.”

In 1908 a 22-year-old Italian baker’s assistant arrived in London to take part in the Olympic marathon. He had no coach, he spoke no English, and he was not expected to challenge the elite runners at the top of the field. In this week’s episode of the Futility Closet podcast we’ll follow Dorando Pietri on the most celebrated race in Olympic history.

We’ll also ponder the Great Mull Air Mystery and puzzle over a welcome murder.

Memory Limit

In 1956 Harvard psychologist George Miller pointed out a pattern he’d observed. If a person is trained to respond to a given pitch with a corresponding response, she’ll respond nearly perfectly when up to six pitches are involved, but beyond that her performance declines. Humans seem to have an “information channel capacity” of 2-3 bits of information: We can distinguish among 4-8 alternatives and respond appropriately, but beyond that number we start to founder.

A similar limit appears in studies of memory span. One psychologist read aloud lists of random items at a rate of one per second and then asked subjects to repeat what they’d heard. No matter what items had been read — words, letters, or numbers — people could store a maximum of about seven unrelated items at a time in their immediate memory.

It’s probably only a coincidence that these tasks have similar limits, but it’s still a useful rule of thumb: The number of objects an average person can hold in working memory is about seven.

Scattered Stars

When I heard the learn’d astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander’d off by myself,
In the mystical moist night-air, and from time to time,
Look’d up in perfect silence at the stars.

That’s Walt Whitman. In 2000, mathematician Mike Keith noted a similar idea in Psalm 19:1-6:

The heavens declare the glory of God;
And the firmament sheweth his handywork.
Day unto day uttereth speech,
And night unto night sheweth knowledge.
There is no speech nor language,
Where their voice is not heard.
Their line is gone out through all the earth,
And their words to the end of the world.
In them hath he set a tabernacle for the sun,
Which is as a bridegroom coming out of his chamber,
And rejoiceth as a strong man to run a race.
His going forth is from the end of the heaven,
And his circuit unto the ends of it:
And there is nothing hid from the heat thereof.

So he married them by rearranging the psalm’s letters:

When I had listened to the erudite astronomer,
When his high thoughts were arranged and charted before me,
When I was shown the length and breadth and height of it,
The Earth, the horned Moon, the chariot of fire,
The hundredth flight of the shuttle through heavyish air,
How soon, mysteriously, I became sad and sick,
Had to wander out, ousted, charging through the forest,
Joining the sure chaos here in a foreign heath,
Having forgotten the vocation of the learned man,
And in the mystic clearing, once more looked up
In perfect silence at the sermon in the stars.

(Michael Keith, “Anagramming the Bible,” Word Ways 33:3 [August 2000], 180-185.)

The Vowel Triangle

Chris McManus discovered this oddity. If W and Y are accepted as vowels, that gives us AEIOUWY. Starting with O, number these according to their positions on a circular alphabet without starting the count over for A (that is, O is the 15th letter of the alphabet, so it’s assigned number 15; beyond Z we’d reach A as the “27th” letter; and so on). Now write these numbers into a triangle, again starting with O:

   O                15
 U W Y           21 23 25
A  E  I         27  31  35

Each of the five lines in the figure gives a different arithmetic progression:

UWY: difference of 2
AEI: difference of 4
OUA: difference of 6
OWE: difference of 8
OYI: difference of 10

(David Morice, “Kickshaws,” Word Ways 34:4 [November 2001], 292-305.)

Fortuitous Numbers

In American usage, 84,672 is said EIGHTY FOUR THOUSAND SIX HUNDRED SEVENTY TWO. Count the letters in each of those words, multiply the counts, and you get 6 × 4 × 8 × 3 × 7 × 7 × 3 = 84,672.

Brandeis University mathematician Michael Kleber calls such a number fortuitous. The next few are 1,852,200, 829,785,600, 20,910,597,120, and 92,215,733,299,200.

If you normally say “and” after “hundred” when speaking number names, then the first few fortuitous numbers are 333,396,000 (THREE HUNDRED AND THIRTY THREE MILLION, THREE HUNDRED AND NINETY SIX THOUSAND), 23,337,720,000, 19,516,557,312,000, 56,458,612,224,000, and 98,802,571,392,000.

And 54 works in both French and Russian.

Sound and Sense

In 1929 linguist Edward Sapir made up two words, mal and mil, and told 500 subjects that one of them meant “large table” and the other “small table.” When asked to tell which was which, 80 percent responded that mal meant “large table” and mil meant “small table” — suggesting that different vowels evoke different sizes.

Four years later, Stanley Newman extended the experiment to include all the vowels. He placed them in a sequence that he said English speakers associate with increasing sizes: i (as in ill), e (met), ae (hat), a (ah), u (moon), o (hole), and so on.

Interestingly, this ranking also reflects the size of the mouth shape needed to pronounce each vowel. “In other words,” writes Peter Farb in Word Play, “the psychological awareness that speakers of English have about what the vowels convey matches the anatomical means of producing them.”

Eric the Robot

In 1928, when London’s Society of Model Engineers received word that the Duke of York would be unable to open its annual exhibition, acting secretary W.H. Richards said, “Very well, I will find a substitute: it is a mechanical show, let us have a mechanical man to open it.”

So they did. Attendees that September were greeted by a robot named Eric who could stand up, bow, look left and right, deliver a four-minute opening address “with appropriate gestures,” and sit down. The speech, imparted by a radio signal, was described as “really sparkling” — apparently literally, as blue sparks shot from Eric’s teeth. From the Model Engineer and Light Machinery Review:

The Exhibition of 1928 has been one of the most successful we ever had. … The ‘Robot’ was a continuous attraction; he drew thousands of people to see his remarkable performance. … It is estimated that he rose and bowed to his audiences more than a thousand times during the week, and he not only amused the majority of his visitors, but positively amazed and bewildered them with his clever movements and conversation.

In 1929 Eric toured America, where he visited Harvard and MIT and informed interviewers that he did not gamble, drink, or run around at night. That’s reassuring, because eventually he disappeared — London Science Museum curator Ben Russell told the Telegraph, “No one quite knows what happened to him, whether he was blown up or taken to pieces for spare parts.” So, working from old photographs, the museum rebuilt him, and he appeared, debonair as ever, in a 2017 exhibition:

War Talk

Just an interesting fragment: When the Chiricahua Apaches of southern Arizona went on a raiding party, they adopted a special speech. One informant told anthropologists Morris Edward Opler and Harry Hoijer:

I used to know many words, but I have forgotten just about all of them. Only one sticks in my mind, and that is the ceremonial way of asking for a drink of water. Instead of saying, ‘I want to drink some water,’ we had to say, ‘I begin to swim the specular iron ore.’

Peter Farb writes in Word Play (1981), “This kind of formal speech had to be maintained until the war party returned to the camp, at which time conversation switched back to everyday language.”

(Morris Edward Opler and Harry Hoijer, “The Raid and War-Path Language of the Chiricahua Apache,” American Anthropologist, New Series, 42:4 Part 1 [October-December 1940], 617-634.)

Bylines appearing in L&N Employees’ Magazine, a house organ of the Louisiana and Nashville Railroad, in the 1940s:

  • R.R. South
  • Steele Raylor
  • Dick C. Lyon
  • Lou Nash
  • L.M. Lynes
  • C. Ross Tye
  • Lincoln Penn
  • Cole Carr
  • M.T. Hopper
  • Rowan House
  • Rowland Stock
  • C.A. Boose

Thinking these fishy, writer Robert Rennick inquired of the railroad’s public relations department and learned that editor Julian James had barred any writer from receiving two bylines in a single issue. So they’d adopted these pseudonyms.

“The assumption was that no reader would ever imagine that these were real names. Yet, W.R. Heffren, writing as C. Ross Tye, once received a letter from a lady genealogist stating that she was researching the Tye family and would he kindly send her his family line to see if it could be related to hers.”
