In 1966, with the Interstate Highway System on the rise and increasing competition from airlines, the New York Central Railroad decided to experiment with a high-speed rail service. The result was startling: a jet-powered railcar.
With two secondhand General Electric J47-19 jet engines mounted above a streamlined cowling, this diesel car reached a speed of 183.68 mph that July on the arrow-straight rail segment between Butler, Indiana, and Stryker, Ohio.
Ultimately the project went nowhere — the company was headed for a merger with the rival Pennsylvania Railroad — but that experimental jaunt still holds the rail speed record in the United States.
The malicious spirit Kuchisake-onna of Japanese folklore wears a mask and carries a sharp object. When you meet her, she asks whether you think she is beautiful. If you answer no, she kills you. If you answer yes, she removes her mask to reveal that the corners of her mouth have been slit open to her ears.
Then she repeats her question. If again you answer no, she kills you. If you answer yes, she cuts your mouth to resemble her own.
Happily, there are at least two ways to escape: describe her appearance as average, or throw hard candies to distract her.
The young specialist in English Lit … lectured me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern ‘knowledge’ is that it is wrong.
… My answer to him was, ‘… when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.’
— Isaac Asimov, The Relativity of Wrong, 1989
(J.R. Deller Jr. wrote, “Education is the process of telling smaller and smaller lies.”)
“Some years ago there was a craze for rolling pellet puzzles,” wrote Henry Dudeney in 1909, “though they are really more trials of patience than puzzles.”
One exception was this undulated glass tube, which contained three shots or pellets. The task was to get them into the three depressions at A, B, and C, which are unfortunately positioned at high points in the tube.
This “could be solved by a puzzle trick which I was surprised to notice how few people discovered,” Dudeney wrote. What was it?
“The trick was to first reverse the tube so that the three depressions, D, E, and F, were at the bottom. It was quite easy to get the shots into these hollows, and when you had them in position you had merely to twist the tube with a quick turn of the fingers, holding it at the ends, when the pellets would fall into the required positions. You could hardly fail once in a hundred attempts, yet I have seen people try the puzzle for hours without success, while this simple trick never occurred to them.”
Played by Japanese priests in the 16th century, taikyoku shogi may be the largest variant of chess ever devised. Each player deploys 402 pieces of 209 types on a board of 1,296 squares to try to capture his opponent’s king(s) and prince(s).
It’s not clear precisely how it was played, but Wikipedia takes more than 10,000 words to describe one likely set of rules.
In the year 4299, five cave explorers are trapped by a landslide. To stay alive they decide to engage in cannibalism, choosing the victim by throwing dice. When the four survivors are rescued, they’re convicted of murder and face a mandatory sentence of death. After a public outcry, the “Supreme Court of Newgarth” takes up the case. Its five judges subscribe to five different legal philosophies, with the result that two vote to affirm the convictions, two vote to overturn them, and one recuses himself. As this is a tie, the original conviction is upheld and the four explorers face death.
Harvard philosopher Lon L. Fuller presented this story in 1949 to contrast various legal philosophies prevailing in the 20th century, primarily natural law and legal positivism.
But in the ensuing years, dozens of further hypotheticaljudgments have been offered by writers from perspectives ranging from historical contextualism to process theory. Frank Easterbrook wrote in 1999 that Fuller’s essay combines “a timely consideration of contemporaneous debates with a timeless quality that continues to entice students and scholars to think and write about [it] some half a century later — and will doubtless engage our successors well into the next millennium.”
Fuller had written, “The case was constructed for the sole purpose of bringing into a common focus certain divergent philosophies of law and government. These philosophies presented men with live questions of choice in the days of Plato and Aristotle. Perhaps they will continue to do so when our era has had its say about them. If there is any element of prediction in the case, it does not go beyond a suggestion that the questions involved are among the permanent problems of the human race.”
“It was hard for me to believe. I would look down and say, ‘This is the moon, this is the moon,’ and I would look up and say, ‘That’s the Earth, that’s the Earth,’ in my head. So it was science fiction to us even as we were doing it.” — Alan Bean, Apollo 12
The first “true cat,” Proailurus, or “Leman’s Dawn Cat,” appeared about 30 million years ago. But from 25 to 18.5 million years ago, strangely few catlike fossils are found in North America. Biologist Luke Hunter writes:
Following the appearance of the dawn cat, there is little in the fossil record for 10 million years to suggest that cats would prosper. In fact, although Proailurus persisted for at least 14 million years, there are so few felid fossils towards the end of the dawn cat’s reign that paleontologists refer to this as the ‘cat gap’. The turning point for cats came about with the appearance of a new genus of felids, Pseudaelurus.
The gap may be due to changes in climate and habitat, the rise of competing doglike species, an unsustainable “hypercarnivorous” dietary specialization, or some other factor. Modern cats descended from Pseudaelurus.
