In 1946, Australian engineer Ben Carlin decided to circle the world in an amphibious jeep. He would spend 10 years in the attempt, which he called an “exercise in technology, masochism, and chance.” In this week’s episode of the Futility Closet podcast we’ll describe Carlin’s unlikely odyssey and the determination that drove him.

We’ll also salute the Kentucky navy and puzzle over some surprising winners.

Pausing

Hi, everyone. I’m going to need to suspend the Futility Closet website for the month of April — we’re fine here, but North Carolina has issued a stay-at-home order due to the pandemic, so I can’t reach my libraries to do the research.

Hopefully we can start up again in May; if not, I’ll post an update here. In the meantime the archive is still available, and we hope to keep producing the podcast during this interval.

If you have any questions you can reach me at greg@futilitycloset.com. Thanks, as always, for reading, and stay safe!

We’ll also celebrate Christmas with Snoopy and puzzle over a deadly traffic light.

British director Cecil Hepworth made “How It Feels To Be Run Over” in 1900. The car is on the wrong side of the road. (The intertitle at the end, “Oh! Mother will be pleased,” may have been scratched directly into the celluloid.)

Hepworth followed it up with “Explosion of a Motor Car,” below, later the same year.

Construct squares outwardly on the sides of triangle ABC, and make a triangle of their centers. Now the centers of squares constructed inwardly on the sides of that triangle will fall on the midpoints of the sides of ABC.

(Due to Luxembourger mathematician Joseph Neuberg, 1840-1926.)

Divining

Playing a trivia game, George S. Kaufman was asked, “What’s the longest river in South America?”

After a lot of stalling, he asked, “Are you sure it’s in South America?”

The Last Banana

A thought experiment in probability by Leonardo Barichello: Two people are stranded on an island with only one banana to eat. To decide who gets it, they agree to play a game. Each of them will roll a fair 6-sided die. If the largest number rolled is a 1, 2, 3, or 4, then Player 1 gets the banana. If the largest number rolled is a 5 or 6, then Player 2 gets it. Which player has the better chance?
