The Jindo Sea Parting

Every year hundreds of thousands of people gather on Jindo Island at the southern tip of the Korean Peninsula to watch the sea part, revealing a 1.8-mile causeway that permits them to walk to the nearby island of Modo, where they dig for clams.

Legend tells that Yongwang, the ocean god, split the sea to permit an old woman to rejoin her family. But National Geographic explains that the truth lies in tidal harmonics.

Men in Aida

In 1983 poet David Melnick reinterpreted the first book of Homer’s Iliad by brutely understanding the spoken Greek as English, producing a bathhouse farce:

Men in Aida, they appeal, eh? A day, O Achilles.
Allow men in, emery Achaians. All gay ethic, eh?
Paul asked if team mousse suck, as Aida, pro, yaps in.
Here on a Tuesday. “Hello,” Rhea to cake Eunice in.
“Hojo” noisy tap as hideous debt to lay at a bully.
Ex you, day. Tap wrote a “D,” a stay. Tenor is Sunday.
Atreides stain axe and Ron and ideas’ll kill you.

In 2015 he published two more books, in each “hearing” Homer’s words as English. He calls it Men in Aïda.

Podcast Episode 188: The Bat Bomb

During World War II, the U.S. Army experimented with a bizarre plan: using live bats to firebomb Japanese cities. In this week’s episode of the Futility Closet podcast we’ll describe the crazy history of the bat bomb, the extraordinary brainchild of a Pennsylvania dentist.

We’ll also consider the malleable nature of mental illness and puzzle over an expensive quiz question.

If squares are drawn on the sides of a triangle and external to it, then the areas of the triangles formed between the squares all equal the area of the triangle itself.

In 1901 Colombia minted special coins for use in leper colonies. Following the first leprosy congress in Berlin in 1897, the nation minted coins in five values for use in three colonies. The Philippines followed suit in 1913, followed by Japan and Malaysia. The United States produced special coins for a colony in the Panama Canal Zone.

The coins were produced to protect healthy people, but in 1938 Gordon Alexander Ryrie, director of Malaysia’s Sungei Buloh Settlement, proved that the disease can’t spread by such casual contact. His colony burned the notes it had printed.

A British Limerick

A young man called Cholmondeley Colquhoun
Kept as a pet a babolquhoun.
His mother said, “Cholmondeley,
Do you think it quite colmondeley
To feed your babolquhoun with a spolquhoun?”

Not Dead Yet

The red-crested tree rat hadn’t been seen since 1898 when one turned up at the front door of a Colombian ecolodge in 2011. It posed for photos for two hours and then disappeared again. “He just shuffled up the handrail near where we were sitting and seemed totally unperturbed by all the excitement he was causing,” said volunteer researcher Lizzie Noble. “We are absolutely delighted to have rediscovered such a wonderful creature after just a month of volunteering with ProAves.”

The Bermuda land snail had been thought extinct for 40 years when it turned up in a Hamilton alleyway. “The fact that there was so much concrete around them probably saved them from the predators that we believe killed the vast majority of the population island-wide,” ecologist Mark Outerbridge told the Royal Gazette. “People have been looking for these snails for decades and here they are surrounded by concrete and air conditioners living in a 100-square-foot alleyway in Hamilton.”

The mountain pygmy possum was first identified in a fossil in New South Wales in 1895 and thought to be extinct. Seventy years later, in August 1966, a live pygmy possum was found by chance in a ski hut in the Snowy Mountains of Victoria. R.M. Warneke telegraphed W.D.L. Ride, “BURRAMYS EXTANT STOP NOT REPEAT NOT EXTINCT STOP LIVE MALE CAPTURED MOUNT HOTHAM STOP AM TRYING FOR FEMALE.” The lonely possum died before a companion could be found, but four isolated populations of pygmy possums are now known to persist in the Snowy Mountains.
