Compound Interest

On Jan. 18, 1897, California farmer George Jones bought a quantity of livestock feed from Henry B. Stuart of San Jose. As security he signed a $100 promissory note that bore 10 percent interest per month, compounded monthly.

They had agreed that Jones would pay the debt in three months, but the note had run for almost 25 years when Stuart got tired of waiting and told his lawyer to sue. Judge J.R. Welch of the Superior Court of Santa Clara entered this judgment on March 6, 1922:

“Wherefore, by virtue of the law and the facts, it is Ordered, Adjudged and Decreed that said Plaintiff have and recover from said Defendant the sum of $304,840,332,912,685.16 with interest thereon at the rate of 7% per annum until paid, together with the further sum of $50.00 Plaintiff’s attorney’s fees herein with interest thereon at the rate of 7% per annum until paid.”

That’s $304 trillion, “more money than there is in the world, outside of Russia,” the New York Tribune reported drily. Jones paid $19.69 and filed for bankruptcy.

Speaking Terms

Indiana University anthropologist Daniel Suslak is compiling a dictionary of Ayapaneco, an indigenous language of Mexico that has only two remaining fluent speakers.

Unfortunately, the two aren’t speaking to each other.

Manuel Segovia, 75, and Isidro Velazquez, 69, live 500 meters apart in the southern state of Tabasco, but “they don’t have a lot in common,” Suslak told the Guardian in April. Segovia can be “a little prickly,” and Velazquez is “more stoic” and rarely leaves his home.

Without their cooperation, Ayapaneco may die out altogether. “When I was a boy everybody spoke it,” Segovia said. “It’s disappeared little by little, and now I suppose it might die with me.”

Divide and Conquer

In 1980, Colorado math teacher William J. O’Donnell was explaining that

divide and conquer 1

when a student noted that

divide and conquer 2

“My immediate reaction was that this student had stumbled onto a special case where this algorithm worked,” O’Donnell wrote in a letter to Mathematics Teacher. “Later, a couple of minutes of work revealed that this technique works for all fractions. Let a, b, c, and d be integers. Then

divide and conquer 3

“Whereas this method can be conveniently applied on occasion, it does not offer the student much advantage when c does not divide a and d does not divide b.”

Sound Choices

Bertrand Russell’s 20 favorite words, given in response to a reader’s inquiry in 1958:

  • wind
  • heath
  • golden
  • begrime
  • pilgrim
  • quagmire
  • diapason
  • alabaster
  • chrysoprase
  • astrolabe
  • apocalyptic
  • ineluctable
  • terraqueous
  • inspissated
  • incarnadine
  • sublunary
  • chorasmean
  • alembic
  • fulminate
  • ecstacy

These are notable, I think, because it appears he wasn’t influenced by meaning.

Confined to an asylum in 1849, poet John Clare made this curious entry in a notebook:

M Drst Mr Cllngwd

Decoding it is simple enough — Clare had removed all vowels and the letter Y. Evidently it was the draft of a letter:

My Dearest Mary Collingwood

I am nearly worn out and want to hear from you — Nobody will own me or have me at any price and what have I done — Do you know what you are in my Debt — kisses for ten years and longer still and longer than that — when people make such mistakes as to call me God’s bastard and whores pay me by shutting me up from God’s people out of the way of common sense and then take my head off because they can’t find me — it out-Herods Herod.

Dearest Mary are you faithful or do you think of me — you know what we said together — you did visit me in hell sometime back but don’t come here again for it is a notorious bad place worse and worse and we are all turned Frenchmen — foolish people tell me I have got no home in this world and as I don’t believe in the other [? undertake] to make myself heaven with my dearest Mary and subscribe myself yours for ever and ever

John Clare

I almost offered this as a puzzle, but it’s too sad. “This is among the most disturbing letters that Clare ever wrote,” notes biographer Jonathan Bate. “It takes us inside his head during a phase of derangement. Even once one has broken the code, it is impossible to decipher the sub-text, especially as we know nothing about the identity of Mary Collingwood beyond the fact that in another of his lists Clare identified her as a Northampton girl.”

Episode

Darth Vader is piloting a barge to Salt Lake City to give a workshop on evildoing. Suddenly he finds himself approaching a crumbling brick aqueduct, at the foot of which is a basket of adorable kittens. He struggles to stop the barge, but it’s too late. The terrified kittens mew piteously, but they’re too weak to escape. Inexorably, implacably, the barge floats out directly over the basket. What happens?

Nothing happens. The barge displaces its weight in water, so there’s no additional load on the aqueduct.

The workshop is a great success.
