cogitabund
adj. musing, meditating, thoughtful, deep in thought

In his Treatise of the System of the World, Isaac Newton imagines firing cannonballs with greater and greater velocity from a high mountaintop. “The body projected with a less velocity, describes the lesser arc VD, and with a greater velocity, the greater arc VE, and augmenting the velocity, it goes farther and farther to F and G; if the velocity was still more and more augmented, it would reach at last quite beyond the circumference of the Earth, and return to the mountain from which it was projected.”

Indeed, if air resistance is not a factor, the cannonball will return to the mountain with the same velocity with which it left it, “and retaining the same velocity, it will describe the same curve over and over, by the same law,” like the moon. Thus with a simple thought experiment Newton conceived that gravity was the key force underlying planetary motion.

In a fitting tribute, the diagram above is now traveling beyond the solar system on the Voyager Golden Record, on a journey that its author helped to make possible.

conticent
adj. keeping silence, silent

As a joke, Elbert Hubbard published an “Essay on Silence” that consisted of 12 blank pages, bound in brown suede and stamped with gold. It was advertised with these testimonials:

“Your elaborate work on ‘Silence’ received, and perused this day. The depth of your argument is perceptible from the start. The continued logic is convincing to the end, and makes its impression on the attentive mind. It is singular how much can be said in a limited space. You are certainly master of our language.” — G.E.Nelson

“Kindly accept my heartiest thanks for your little volume on ‘Silence.’ The subject is treated so exhaustively, and in such a quaintly original manner, that it is beyond the pale of criticism.” — Alex L. Pach

“Your valuable ‘Essay on Silence’ is a masterpiece, for it appeals to one in purity, like a cloudless sky. The language is grand as the voice of God; the story it tells is as deep in its meaning as that which is written on the pages of the book of Nature.” — Albert J. Atkins

“Your ‘Essay on Silence’ is all that the bills promised, and could not be more to the point. Thirty cents is exactly the right price.” — Alice L. LeCouver

“It is with great pleasure that I have looked into your ‘Essay on Silence.’ There is nothing in it to prevent its becoming a classic. No word has been wasted, and there is not one line that can be misunderstood. In the perusal of many writings, we realize that the same thought has been framed in our own minds without having been given an utterance; and so it is that this last work of yours has found me most sympathetic and appreciative, for in turning over your pages I am struck frequently with resemblances to my own mental condition. Your little book is simple, direct and convincing. I am reminded, in putting it down, of a certain passage in the biblical story, in which it is set forth that from nothing God made heaven and earth and all that therein is, consequently it is not surprising that you in this case have done so well.” — George W. Stevens

tripudiary
adj. pertaining to dancing

Hermit crabs adopt other creatures’ castoff shells for protection. But as they grow, crabs must move into successively larger shells. This produces a curious phenomenon: When a crab finds a shell that’s too big for it, it waits nearby. Other crabs may accumulate, forming a little conga line of dissatisfied shell seekers. Finally a “Goldilocks” crab arrives — a crab large enough to claim the new shell — and now each waiting crab can move into the shell abandoned by its larger neighbor. By cooperating to share a scarce resource, the whole species benefits.

The same thing happens in human societies — when one person finds a new apartment, car, or job, she leaves behind her old one, and the vacancy passes down through society until the final unit is cast away or destroyed. It’s called a vacancy chain.

Among Union Army regiments, the 33rd Illinois became known as the “brains” regiment because it contained so many teachers. “It was stated derisively that the men would not obey orders which were not absolutely correct in syntax and orthography and that men who were discharged from it for mental incapacity, at once secured positions as officers in other regiments.” Many of them came from Illinois State Normal University; of the 97 teachers and pupils on the university’s rolls in 1860-1861, 53 entered the army.

Another puzzle by Yakov Perelman:

“Two fathers gave their two sons some money. One gave his son 150 rubles and the other 100 rubles. When the two sons counted their finances, they found that together they had become richer by only 150 rubles. What is the explanation?”

adj. abusive, foul-mouthed, reviling

In his Recollections of the Civil War, Charles Anderson Dana called Union general Andrew Atkinson Humphreys “one of the loudest swearers that I ever knew.” “The men of distinguished and brilliant profanity in the war were General Sherman and General Humphreys — I could not mention any others that could be classed with them. General Logan also was a strong swearer, but he was not a West Pointer: he was a civilian. Sherman and Humphreys would swear to make everything blue when some dispatch had not been delivered correctly or they were provoked.”

In Rex v. Sparling (1722), a leather dresser named James Sparling was alleged in the course of 10 days to “profanely swear fifty-four oaths, and profanely curse one hundred and sixty curses, contra formam statuti.” His conviction was overturned because the charge sheet had failed to list them. “For what is a profane oath or curse is a matter of law, and ought not to be left to the judgment of the witness … it is a matter of great dispute among the learned, what are oaths and what curses.”

When in 1985 a man named Callahan called a California highway patrolman a “fucking asshole,” California Court of Appeal Justice Gerald Brown referred to this phrase as the “Callahan epithet” to avoid having to repeat it continuously, “which arguably would assist its passage into parlor parlance.” And he reversed Callahan’s conviction:

A land as diverse as ours must expect and tolerate an infinite variety of expression. What is vulgar to one may be lyric to another. Some people spew four-letter words as their common speech such as to devalue its currency; their repetition dulls the senses; Billingsgate thus becomes commonplace. Not everyone can be a Daniel Webster, a William Jennings Bryan or a Joseph A. Ball. …

Fifty years ago the words ‘damn’ and ‘hell’ were as shocking to the sensibilities of some people as the Callahan epithet is to others today. The first word in Callahan’s epithet has many meanings. When speaking about coitus, not everyone can be an F.E. Smith (later Earl of Birkenhead) who, in his speech in 1920 in the House of Commons on the Matrimonial Causes Act, referred to ‘that bond by which nature in its ingenious telepathy has contrived to secure and render agreeable the perpetuation of the species.’

“Special Correspondence. I learn from a very high authority, whose name I am not at liberty to mention, (speaking to me at a place which I am not allowed to indicate and in a language which I am forbidden to use) — that Austria-Hungary is about to take a diplomatic step of the highest importance. What this step is, I am forbidden to say. But the consequences of it — which unfortunately I am pledged not to disclose — will be such as to effect results which I am not free to enumerate.” — Stephen Leacock, The Hohenzollerns in America, 1919
