Podcast Episode 343: Operation Cowboy

In April 1945, a group of American soldiers learned that hundreds of Lipizzaner horses were being held on a farm in western Czechoslovakia — and set out to rescue them before the Red Army could reach them. In this week’s episode of the Futility Closet podcast we’ll tell the story of Operation Cowboy, one of the strangest episodes of World War II.

We’ll also learn about an NBA brawl and puzzle over a technology’s link to cancer deaths.

The gravestone of urban planner Ildefons Cerdà has a unique design: It commemorates the Eixample, the distinctive “extension” of Barcelona that Cerdà designed in the 19th century.

Amplitude

This passage, from E.B. White’s Charlotte’s Web, is often cited as a masterpiece of rhythm — the length of the phrases diminishes with the motion of the swing:

Mr. Zuckerman had the best swing in the county. It was a single long piece of heavy rope tied over the north doorway. At the bottom end of the rope was a fat knot to sit on. It was arranged so that you could swing without being pushed. You climbed a ladder into the hayloft. Then, holding the rope, you stood at the edge and looked down, and were scared and dizzy. Then you straddled the knot, so that it served as a seat. Then you got up all your nerve, took a deep breath, and jumped. For a second you seemed to be falling to the barn floor far below, but then suddenly the rope would begin to catch you, and you would sail through the barn door going a mile a minute, with the wind whistling in your eyes and ears and hair. Then you would zoom upward into the sky, and look up at the clouds, and the rope would twist and you would twist and turn with the rope. Then you would drop down, down, down out of the sky and come sailing back into the barn almost into the hayloft, then sail out again (not quite so far this time), then in again (not quite so high), then out again, then in again, then out, then in; and then you’d jump off and fall down let somebody else try it.

“All that I hope to say in books, all that I ever hope to say, is that I love the world,” White wrote. Though Eudora Welty called Charlotte’s Web “just about perfect,” White never revealed his reason for creating it. “I haven’t told why I wrote the book, but I haven’t told you why I sneeze, either,” he wrote to his editor. “A book is a sneeze.”

Match Point

A problem from the Leningrad Mathematical Olympiad: A and B take turns removing matches from a pile. The pile starts with 500 matches, A goes first, and the player who takes the last match wins. The catch is that the quantity that each player withdraws on a given turn must be a power of 2. Does either player have a winning strategy?

The Nightingale Monument

https://www.reddit.com/r/Damnthatsinteresting/comments/mo2i8k/the_tomb_of_lady_elizabeth_nightingale_who_died/

Elizabeth Nightingale died of shock at a violent stroke of lightning following the premature birth of her daughter in 1731. In his will, her son ordered the erection of this monument, which was created by Louis Francois Roubiliac and stands in Westminster Abbey. Elizabeth is supported by her husband, who tries in horror to ward off the stroke of death. Washington Irving called it “among the most renowned achievements of modern art.”

The Abbey’s website says, “The idea for this image may have come from a dream that Elizabeth’s brother in law (the Earl of Huntingdon) had experienced when a skeleton had appeared at the foot of his bed, which then crept up under the bedclothes between husband and wife. … It is said that one night a robber broke into the Church but was so horrified at seeing the figure of Death in the moonlight that he dropped his crowbar and fled in terror. The crowbar was displayed for many years beside the monument but it no longer remains.”

During an eclipse in 1919, Sir Arthur Eddington confirmed Albert Einstein’s prediction of the gravitational bending of light rays, upholding the general theory of relativity. That Christmas, Einstein wrote to his friend Heinrich Zangger in Zurich:

“With fame I become more and more stupid, which, of course, is a very common phenomenon. There is far too great a disproportion between what one is and what others think one is, or at least what they say they think one is. But one has to take it all with good humor.”

(From Helen Dukas and Banesh Hoffmann, eds., Albert Einstein, the Human Side: New Glimpses From His Archives, 1979.)

The Seconds Pendulum

An interesting historical fact from these MIT notes: Christiaan Huygens proposed defining the meter conveniently as the length of a pendulum that produces a period of 2 seconds. A pendulum’s period is

\displaystyle  T = 2\pi \sqrt{\frac{l}{g}},

so, using Huygens’ standard of T = 2s for 1 meter,

\displaystyle  g = \frac{4\pi ^{2}\times 1\ \textup{meter}}{4s^{2}} = \pi ^{2}ms^{-2}.

“So, if Huygens’s standard were used today, then g would be π2 by definition.”
