In 1943 an isolated sledge patrol came upon a secret German weather station in northeastern Greenland. The discovery set off a series of dramatic incidents that unfolded across 400 miles of desolate coast. In this week’s episode of the Futility Closet podcast we’ll follow this arctic struggle, an often overlooked drama of World War II.

We’ll also catch some speeders and puzzle over a disastrous remedy.

The Spirit Battery

https://books.google.com/books?id=FtEPAAAAYAAJ&pg=PA101

When the electric telegraph was making its appearance in the 1840s, it was strangely easy to confuse it with spiritualism: Both were uncanny means of talking with absent people through systems of symbols. In a bid for legitimacy, spiritualists appealed to the principles of “electrical science.” In his 1853 book The Present Age and Inner Life, Andrew Jackson Davis proposed a “spirit battery” by which a medium could improve her contact with the spirit world by asking her guests to hold a magnetic rope whose ends were dipped in water-filled buckets made of copper and zinc:

The males and females (the positive and negative principles) are placed alternately; as so many zinc and copper plates in the construction of magnetic batteries. The medium or media have places assigned them on either side of the junction whereat the rope is crossed, the ends terminating each in a pail or jar of cold water. … But these new things should be added. The copper wire should terminate in, or be clasped to, a zinc plate; the steel wire should, in the same manner, be attached to a copper plate. These plates should be dodecahedral, or cut with twelve angles or sides, because, by means of the points, the volume of terrestrial electricity is greatly augmented, and its accumulation is also, by the same means, accelerated, which the circle requires for a rudimental aura (or atmosphere) through which spirits can approach and act upon material bodies.

“We are negative to our guardian spirits; they are positive to us,” Davis wrote. “The whole mystery is illustrated by the workings of the common magnetic telegraph. The principles involved are identical.”

Alarming bonus factoid: When Samuel Morse appeared before Congress in 1838 to seek funding for an experimental telegraph line, some congressmen introduced amendments that would provide funds for research on mesmerism as well. The committee chair wrote, “It would require a scientific analysis to determine how far the magnetism of mesmerism was analogous to the magnetism to be employed in telegraphs.” When the bill came to a vote, 70 congressmen left their seats; many hoped “to avoid spending the public money for a machine they could not understand.”

In 1914, 132 sealers found themselves stranded on a North Atlantic icefield as a bitter blizzard approached. Thinly dressed and with little food, they faced a harrowing night on the ice. In this week’s episode of the Futility Closet podcast we’ll tell the story of the Newfoundland sealing disaster, one of the most dramatic chapters in Canadian maritime history.

We’ll also meet another battlefield dog and puzzle over a rejected necklace.

In German East Africa during World War I, soldiers painted this pony to resemble one of the local zebras so it could be tethered in the open.

The Imperial War Museum adds, “Two white ponies behind anxiously await their makeovers.”

In June 1940, German forces took the Channel Islands, a small British dependency off the coast of France. They expected the occupation to go easily, but they hadn’t reckoned on the island of Sark, ruled by an iron-willed noblewoman with a disdain for Nazis. In this week’s episode of the Futility Closet podcast we’ll tell the story of Sibyl Hathaway and her indomitable stand against the Germans.

We’ll also overtake an earthquake and puzzle over an inscrutable water pipe.

Tight Squeeze

A related puzzle from The Chicken From Minsk, Yuri B. Chernyak’s 1995 collection of math and physics problems: Why is it easier to parallel-park a (conventional) car by backing into the space rather than pulling in directly?

In 1800 a 12-year-old boy emerged from a forest in southern France, where he had apparently lived alone for seven years. His case was taken up by a young Paris doctor who set out to see if the boy could be civilized. In this week’s episode of the Futility Closet podcast we’ll explore the strange, sad story of Victor of Aveyron and the mysteries of child development.

We’ll also consider the nature of art and puzzle over the relationship between salmon and trees.

Podcast Episode 251: Joseph Palmer’s Beard

https://books.google.com/books?id=Wc0QAAAAYAAJ&pg=PA56

In 1830 Joseph Palmer created an odd controversy in Fitchburg, Massachusetts: He wore a beard when beards were out of fashion. For this social sin he was shunned, attacked, and ultimately jailed. In this week’s episode of the Futility Closet podcast we’ll tell the story of a bizarre battle against irrational prejudice.

We’ll also see whether a computer can understand knitting and puzzle over an unrewarded long jump.

The Apology Paradox

We ought to apologize for what our ancestors did to other people. This requires that we sincerely regret those deeds. But that means that we would prefer that the deeds had not been done, and if this were the case then world history would be significantly different and we ourselves would probably not exist. Yet most of us are glad to be alive. Can we sincerely regret deeds that are necessary to our own existence?

(That’s from La Trobe University philosopher Janna Thompson. She says the best solution is to interpret the apology as regret for this state of affairs. “[T]he regret expressed is that we owe our existence and other things we enjoy to the injustices of our ancestors. Our preference is for a possible world in which our existence did not depend on these deeds.”)

(Janna Thompson, “The Apology Paradox,” Philosophical Quarterly 50:201 [2000], 470-475.)

Podcast Episode 250: The General Slocum

https://books.google.com/books?id=lHOs2j3cuYwC

In 1904 a Manhattan church outing descended into horror when a passenger steamboat caught fire on the East River. More than a thousand people struggled to survive as the captain raced to reach land. In this week’s episode of the Futility Closet podcast we’ll describe the burning of the General Slocum, the worst maritime disaster in the history of New York City.

We’ll also chase some marathon cheaters and puzzle over a confusing speeding ticket.
