Eodermdromes

A spelling net is the pattern made when one writes down one instance of each unique letter that appears in a word and then connects these letters with lines, spelling out the word. For instance, the spelling net for VIVID is made by writing down the letters V, I, and D and drawing a line from V to I, I to V, V to I, and I to D.

Different words produce different spelling nets, of course, but every spelling net is an example of a graph, a collection of points connected by lines. A graph is said to be non-planar if some of the lines must cross; in the case of the spelling net, this means that no matter how we arrange the letters on the page, when we connect them in order we find that at least two of the lines must cross.

A word with a non-planar spelling net is called an eodermdrome, an ungainly name that itself illustrates the idea. The unique letters in EODERMDROME are E, O, D, R, and M. Write these down and run a pen among them, spelling out the word. You’ll find that no matter how the letters are arranged, it’s never possible to complete the task without at least two of the lines crossing:

Ross Eckler sought all the eodermdromes in Webster’s second and third editions; another example he found is SUPERSATURATES:

Since spelling nets are graphs, they can be studied with the tools of graph theory, the mathematical study of such networks. One result from that discipline says that a graph is non-planar if and only if it can be reduced to one of the two patterns marked K5 and K(3, 3) above. Since both EODERMDROME and SUPERSATURATES contain these forbidden graphs, both are non-planar.

A good article describing recreational eodermdrome hunting, by computer scientists Gary S. Bloom, John W. Kennedy, and Peter J. Wexler, is here. One warning: They note that, with some linguistic flexibility, the word eodermdrome can be interpreted to mean “a course on which to go to be made miserable.”

In 1726, the Swiss naturalist Johann Jakob Scheuchzer mistook the skull and vertebral column of a large salamander from the Miocene epoch for the “betrübten Beingerüst eines alten Sünders” (sad bony remains of an old human sinner) and dubbed it Homo diluvii testis, “the man who witnessed the Deluge.” The fossil lacked a tail or hind legs, so he thought it was the remains of a trampled human child:

It is certain that this [rock] contains the half, or nearly so, of the skeleton of a man; that the substance even of the bones, and, what is more, of the flesh and of parts still softer than the flesh, are there incorporated in the stone; in a word it is one of the rarest relics which we have of that accursed race which was buried under the waters. The figure shows us the contour of the frontal bone, the orbits with the openings which give passage to the great nerves of the fifth pair. We see there the remains of the brain, of the sphenoidal bone, of the roots of the nose, a notable fragment of the maxillary bone, and some vestiges of the liver.

The fossil made its way to Teylers Museum in the Netherlands, where in 1811 Georges Cuvier recognized it as a giant salamander. Ironically, Scheuchzer’s original belief is reflected in the fossil’s modern name, Andrias scheuchzeri — Andrias means “image of man.”

Footloose

A visitor’s description of William Kingston, a Somerset farmer born without arms, recounted in John Platts, Encyclopedia of Natural and Artificial Wonders and Curiosities, 1876:

He highly entertained us at breakfast, by putting his half-naked feet upon the table as he sat, and carrying his tea and toast between his great and second toe to his mouth, with as much facility as if his foot had been a hand, and his toes fingers. … He then shewed me how he shaves himself with the razor in his toes; and he can comb his own hair. He can dress and undress himself, except buttoning his clothes. He feeds himself, and can bring both his meat or his broth to his mouth, by holding the fork or spoon in his toes. He cleans his own shoes, lights the fire, and does almost any domestic business as well as any other man. … He can milk his cows with his toes, and cuts his own hay, binds it up in bundles, and carries it about the field for his cattle. Last winter he had eight heifers constantly to fodder. The last summer he made all his hay-ricks. He can do all the business of the hay-field (except mowing) as fast and as well with his feet as others can with rakes and forks. … In a word, he can nearly do as much without as others can with their arms.

A Pretty Find

Write the word CESAROLITE in a circle and then trace out the letters in its anagram ESOTERICAL — the result is a perfect 10-pointed star:

Only 5.7 percent of anagrams in English are “maximally shuffled,” meaning that no letter retains its original neighbors. And even those rarely produce such pleasing symmetry when they’re diagramed like this. This is the largest “perfect” star anagram found in a systematic search by Jason Parker and Dan Barker; for more, see the link below.

“Hence These Rimes”

Tho’ my verse is exact,
Tho’ it flawlessly flows,
As a matter of fact
I would rather write prose.

While my harp is in tune,
And I sing like the birds,
I would really as soon
Write in straightaway words.

Tho’ my songs are as sweet
As Apollo e’er piped,
And my lines are as neat
As have ever been typed,

I would rather write prose —
I prefer it to rime;
It’s less hard to compose,
And it takes me less time.

“Well, if that be the case,”
You are moved to inquire,
“Why appropriate space
For extolling your lyre?”

I can only reply
That this form I elect
‘Cause it pleases the eye,
And I like the effect.

— Bert Leston Taylor

The Tortoise stepped ever so carefully across the finish line, just a moment before the Hare would have been about to be going to hop across it himself. ‘I won!’ she said. The Hare paused a moment, then replied, ‘Yes, Ms. Tortoise, in the next decade you will have been about to be going to be used to be having been doing being the winner of this race, but tomorrow we’ll have to do it again, for it’s two out of three, ma’am.’
