“If you bet on a horse, that’s gambling. If you bet you can make three spades, that’s entertainment. If you bet cotton will go up three points, that’s business. See the difference?” — Blackie Sherrod

Podcast Episode 185: The Man From Formosa
In 1703, London had a strange visitor, a young man who ate raw meat and claimed that he came from an unknown country on the island of Taiwan. Though many doubted him, he was able to answer any question he was asked, and even wrote a best-selling book about his homeland. In this week’s episode of the Futility Closet podcast we’ll consider the curious question of the man from Formosa.
We’ll also scrutinize a stamp forger and puzzle over an elastic Utah.
Self-Ancestors
A 1907 magazine reports two curiously ingrown family trees. The first is that of an alleged Neapolitan sailor:
I married a widow. She had by her first husband a handsome girl named Silvietta, with whom my father fell in love and who became his second wife. Thus my father became my son-in-law and my stepdaughter became my mother, since she had married my father. Soon afterward my wife gave birth to a son, who became my father’s stepbrother and at the same time my uncle, since he was my stepmother’s brother.
But that was not all, for in due time my father’s wife also gave birth to a boy, who was my brother and also my stepson [grandson?], since he was the son of my daughter. My wife was also my grandmother, for she was the mother of my mother, and thus I was my wife’s husband and at the same time her grandson. Finally, as the husband of a person’s grandmother is naturally that person’s grandfather, I am forced to the conclusion that I am my own grandfather.
We’ve seen that before, but the second story describes a more complicated route to the same outcome. Fifteen-year-old Ida Kriebel of Pennsylvania married 60-year-old Jacob Doney and became her own grandmother:
Domey’s first wife was the widow of John Wieden. She had three more children by Doney. One of her children married Samuel Kriebel, and a year later died. The widower married again. From this second union came Ida Kriebel. By this arrangement Doney became the stepgrandfather of his own child [wife?].
“The second Mrs. Doney also became stepgrandmother of twenty-five men and women, and stepgreat-grandmother of a lot of boys and girls of about her own age.”
A Triangle Calculator
Edric Cane came up with a simple way to establish any row in Pascal’s triangle, creating a simple sequence of fractions that, when multiplied successively, will produce the numbers in any desired row. Here’s an example for Row 7, giving the coefficients for (a + b)7 = a7 + 7a6b + 21a5b2 + 35a4b3 + 35a3b4 + 21a2b5 + 7ab6 + b7:
Another example, for Row 10:
The same can be done for any desired row.

Theme and Variations
All of Johann Sebastian Bach’s surviving brothers were named Johann: Johann Rudolf, Johann Christoph, Johann Balthasar, Johannes Jonas, and Johann Jacob. His father was Johann Ambrosius Bach, and his sister was Johanna Juditha.
By contrast, his other sister, Marie Salome, “stuck out like a sore thumb,” writes Jeremy Siepmann in Bach: Life and Works. “And they all had grandparents and uncles and cousins whose names were also Johann, something. Johann Sebastian’s own children included Johann Gottfried, Johann Christoph, Johann August, Johann Christian, and Johanna Carolina.”

Some Odd Words
Doubtful but entertaining:
Several sources define vacansopapurosophobia as “fear of blank paper” — it’s not in the Oxford English Dictionary, but it’s certainly a useful word.
I’ve also seen artiformologicalintactitudinarianisminist, “one who studies 4-5-letter Latin prefixes and suffixes.” I don’t have a source for that; it’s not in the OED either.
In Say It My Way, Willard R. Espy defines a cypripareuniaphile as “one who takes special pleasure in sexual intercourse with prostitutes” and acyanoblepsianite as “one who cannot distinguish the color blue.”
In By the Sword, his history of swordsmen, Richard Cohen defines tsujigiri as “to try out a new sword on a chance passerby.” Apparently that’s a real practice.
And one that is in the OED: mallemaroking is “the boisterous and drunken exchange of hospitality between sailors in extreme northern waters.”

Footwork
Miss Alice E. Lewis sent this curiosity to the Strand in 1903:
These false horseshoes were found in the moat at Birtsmorton Court, near Tewkesbury. It is supposed that they were used in the time of the Civil Wars, so as to deceive any person tracking the marks. The one on the left is supposed to leave the mark of a cow’s hoof, the one on the right that of a child’s foot.
The same idea has been used by moonshiners and patented at least twice. Does this really work?

An Odd Fact
Mentioned in James Tanton’s Mathematics Galore!:
In 1740 the French mathematician Philippe Naudé sent a letter to Leonhard Euler asking how many ways a positive integer could be written as a sum of distinct positive integers (regardless of their order). In considering the problem Euler found something remarkable.
Let D(n) be the number of ways to write n as a sum of distinct positive integers. So, for example, D(6) is 4 because there are four ways to do this for 6: 6, 5 + 1, 4 + 2, and 3 + 2 + 1.
And let O(n) be the number of ways to write n as a sum of odd integers. So O(6) is 4 because 6 can be written as 5 + 1, 3 + 3, 3 + 1 + 1 + 1, or 1 + 1 + 1 + 1 + 1 + 1.
Euler showed that O(N) always equals D(N).
The Mechanics of History
Like his Celui qui tombe of 2014, acrobat Yoann Bourgeois’s La mécanique de l’Histoire is entirely abstract and yet freighted with meaning.
He presented it at the Panthéon in Paris last year — the site of Léon Foucault’s original rotation-demonstrating pendulum.
