Ferdinand Demara earned his reputation as the Great Impostor: For over 22 years he criss-crossed the country, posing as everything from an auditor to a zoologist and stealing a succession of identities to fool his employers. In this week’s episode of the Futility Closet podcast we’ll review Demara’s motivation, morality, and techniques — and the charismatic spell he seemed to cast over others.
We’ll also make Big Ben strike 13 and puzzle over a movie watcher’s cat.
Suppose we have a group of officers in six regiments, each regiment consisting of the same six ranks (say, a colonel, a lieutenant colonel, a major, a captain, a first lieutenant, and a second lieutenant). Is it possible to arrange these 36 officers into a 6 × 6 square so that no rank or regiment is repeated in any row or column? That is, each row and column must contain an officer of each regiment and of each rank.
In 1782 Leonhard Euler wrote, “After we have put a lot of thought into finding a solution, we have to admit that such an arrangement is impossible, though we can’t give a rigorous demonstration of this.” He saw that the equivalent problem is impossible in a 2 × 2 square and surmised that it’s impossible in every case where the side of the square contains 4k + 2 cells.
It wasn’t until 1901 that French mathematician Gaston Terry proved that the 6 × 6 square has no solution, and it wasn’t until 1960 that Euler’s conjecture about the pattern of impossible squares was proven wrong: In fact, the task is impossible only in these two cases, 2 × 2 and 6 × 6.
Nathan Bailey’s Universal Etymological Dictionary of 1764 defines thunder as “a noise known by persons not deaf.”
Butterflies in the genus Diaethria are commonly called “eighty-eights” because their wings bear a pattern that resembles the number 88 or 89.
The Australian ringneck parrot has four subspecies, one of which is known as the 28 parrot for its triple-noted call, which sounds like “twentee-eight.”
Each year on August 1 the city of Warsaw comes to a voluntary standstill for one minute at 5 p.m.
It’s done to honor those who fought for freedom during the Warsaw Uprising, which began at that hour on August 1, 1944.
This is neat: Figure 1 in this physics paper is a 1:1 scale image of a primordial black hole whose mass is 5 times that of Earth.
A black hole of 10 Earth masses “is roughly the size of a ten pin bowling ball.”

In the 11th century, sailors in the Mediterranean developed a pidgin language to communicate with one another, a mix of Italian, Spanish, Catalan, Galician, Portuguese, Occitan, French, Latin, English, and other languages in which they could conduct trade and diplomacy. Known as Sabir, it appears briefly in Molière’s comedy Le Bourgeois gentilhomme when the Mufti sings:
Se ti sabir
Ti respondir
Se non sabir
Tazir, tazir
Mi star Mufti:
Ti qui star ti?
Non intendir:
Tazir, tazir.
This means:
If you know
You answer
If you do not know
Be silent, be silent
I am Mufti
Who are you?
If you do not understand,
Be silent, be silent
The language persisted into the 19th century, and traces of it can still be found in modern slang and in geographical names.

Why do we enjoy sad fiction? In 2009 Boston College psychologist Thalia Goldstein asked 59 subjects to rate the sadness and anxiety they felt in response to four film clips (two presented as fictional, two as factual) and to their own memory of a sad event they’d experienced personally. While they reported equivalent levels of sadness in response to all these things, their anxiety level was significantly higher when recalling their own experience.
“Apparently we do not mind experiencing intense sadness if that sadness is not tinged with anxiety,” Goldstein writes. Indeed, that might make it more cathartic. And because we know that we can walk away from a fictional sadness, we may feel safer suspending our disbelief to explore and understand our feelings deeply.
