Peak Performance

This is fascinating if it’s true: Ten municipalities meet at the summit of Mount Etna, producing a “decipoint” and one of the most complex arrangements of political boundaries outside Antarctica.

I say “if it’s true” because, for such a striking fact, it’s surprisingly hard to confirm. Many sources point to a blog post at Condé Nast Traveler by Jeopardy champion Ken Jennings, but that cites no source.

On the other hand, no one else seems to doubt it, and this map by Patrick McGranaghan won the American Geographical Society’s monthly map contest in November 2017. Maybe I’m too skeptical?

09/21/2023 UPDATE: Wow, it seems to be true. The official website of the Parco dell’Etna includes a map (PDF) showing the distribution of comuni metropolitani around the peak. And the website of the Italian National Institute of Statistics offers data files on statistical districts that can be opened using the desktop version of Google Earth. Many thanks to readers Rob Miller and Ross Ogilvie for looking into this.

For What It’s Worth

A 2009 study in the journal Sex Roles found that James Bond had had “strong” sexual contact with 46 women in the first 20 films in the Eon Productions Bond series (up to Die Another Day).

He had “mild” encounters, such as kissing, with another 52.

For comparison, Bond author Henry Chancellor had counted 58 sexual encounters in the first 20 films (according to Ben MacIntyre in For Your Eyes Only). Interestingly, Chancellor calculated that Bond sleeps with just 14 women in the 12 books that appeared between 1953 and 1964.

Still, that’s a lot of partners. “The likelihood of James Bond having chlamydia is extremely high,” general practitioner Sarah Jarvis told the BBC. “If he came to my clinic I would definitely advise him to have an STI test.”

On a standard calculator keypad like the one shown here, any four-digit number that is typed in a rectangular shape is evenly divisible by 11. Some examples: 7964, 6523, 1793, 7128. (The numbers must not include 0.)

Parallelograms work too: 1562, 6875, 2783, etc.

Discussion and some proofs here.

09/20/2023 More: Take three digits in order from any row, column, or main diagonal and append the same three digits in reverse order (e.g., 951159). The resulting number will always be evenly divisible by 37 (and, indeed, by 1221). Mathematical Gazette, December 1986 and June 1987. See also A Keypad Oddity.

Four-Mile Fall

In January 1942, Soviet Air Force lieutenant Ivan Mikhailovich Chisov was serving as navigator on an Ilyushin Il-4 bomber when an attack by Messerschmitt fighters forced him to bail out.

He left the plane at 6,700 meters and decided to forgo opening his parachute until he’d dropped below the level of the battle. But due to the thin atmosphere he passed out before he could pull the ripcord.

At an estimated 200 kph he struck the edge of a ravine whose steep sides were covered in deep snow. He tumbled to the bottom, where cavalrymen found him alive and still wearing his unopened parachute. He spent a month in critical condition with a broken pelvis but was flying again three months later.

Play On

Local rules adopted at British golf courses during World War II:

  • “In competitions, during gunfire or while bombs are falling, players may take cover without penalty for ceasing play.”
  • “The positions of known delayed-action bombs are marked by red flags placed at a reasonably, but not guaranteed, safe distance therefrom.”
  • “A ball moved by enemy action may be replaced, or if lost or destroyed, ball may be dropped not nearer the hole without penalty.”
  • “A player whose stroke is affected by the simultaneous explosion of a bomb may play another ball from the same place. Penalty one stroke.”

In Curiosities of Golf (1994), Jonathan Rice writes, “At Folkestone GC, the wartime rules included the rather grudging allowance that ‘a ball may be lifted and dropped if in a bomb hole in the rough, but not if the bomb hole is in or part of a recognized hazard.’ So if you sliced your drive and just caught a bunker by the side of the fairway, which then turned out to be fifty feet deep thanks to an overnight bombing raid, you just had to play out of the hazard, however unrecognizable it might have been compared with the day before. They breed tough golfers in Folkestone.”

In July 1941, some American clubs reportedly adopted similar rules in a show of solidarity.

UPDATE: Here are the rules adopted by Richmond GC, southwest of London. (Thanks, Brieuc.)

Nineteenth-century personal ads from the New York Herald:

The Book of Truth

Once I read a book of 100 numbered pages with one sentence on each page. Page 1: ‘The sentence on page 2 is true.’ Page 2: ‘The sentence on page 3 is true.’ And so on to page 100: ‘The sentence on page 1 is false.’

On the second reading, page 100 changes the entire book. If page 1 is false, then the truth is ‘The sentence on page 2 is false.’ Likewise, page 2 becomes ‘The sentence on page 3 is false.’ And so on to page 100, which now should be read as ‘The sentence on page 1 is true.’

What happens on the third reading?

In 1980, after 30 years of drawing Beetle Bailey, comic artist Mort Walker published The Lexicon of Comicana, a lighthearted meditation on the many conventions that a reader of comic strips is expected to understand. He calls it a lexicon because he’s made up names for all of them:

  • A grawlix (above) is a string of symbols representing profanity.
  • Emanata are lines surrounding a character’s head to indicate surprise or shock.
  • A lucaflect is the distorted image of a window in a shiny object.
  • Blurgits are blurs of motion within a single panel, to denote frenzied action.
  • Sphericasia are lines tracking motion: a throwatron is a line following a football, a sailatron follows a wandering paper airplane, and a dashed staggeratron follows an intoxicated person. If the motion is particularly fast, these might begin with a dust cloud, called a briffit.
  • Plewds are flying droplets of sweat to indicate stress, hard work, or nerves.
  • An indotherm is a series of wavy lines to indicate rising heat.
  • Vites are fine vertical lines to indicate a shine on a floor. Strangely, a window or mirror bears dites, which are diagonal.

More: a light bulb represents an idea, Zs (or a saw cutting a log) represent snoring, distant birds are inverted Ws, patches denote poverty, all bones are the same shape, all new things have price tags, all injuries require bandages, all paint cans bear drippings. Who invented all these conventions, and how did we all learn to observe them?
