Meiji Institute mathematician Kokichi Sugihara (he of the reverse-gravity ramps) devised this separate illusion in 2018 — an arrow that points in only one direction.

I was just researching wartime superstitions and came across this striking anecdote. Major Hubert Knilans was an American bomber pilot who flew with the No. 619 Squadron in the RAF during World War II. As he was climbing to cruising altitude one evening, “The upper sky before me was still somewhat lighted. A figure of a woman several thousand feet high slowly emerged into my startled view.”

He realized she had the face of a young woman he’d loved but who had died suddenly of pneumonia some years earlier. “She had a slight smile on her lips as I flew towards her. The vision slowly melted into the darkening sky around us.”

He says he was “a bit uneasy” over this vision, uncertain “if she had appeared to reassure me that she would keep me from harm or if she was welcoming me into her world of the hereafter.”

Apparently it was the former — he finished the mission successfully and wrote up the encounter in his private memoir A Yank in the RCAF.

Your beloved daughter is spending the summer at a Japanese monastery. On July 28 you receive a letter from an administrator, dated July 19, saying that she needs to have her wisdom teeth removed. The availability of drugs is not certain: She’ll either have a relatively painful extraction on July 27 or an unpleasant but painless one on July 29. Learning of this situation from afar, which drug would you prefer to have been available?

Now imagine that you receive the letter on July 26 and jet to her bedside. You arrive on July 28 to find her asleep. She seems a little restless, but you don’t know whether that’s because she had a painful extraction yesterday or because she’s anxious about having an unpleasant one tomorrow. Now which do you prefer?

“I find that the large majority of people to whom I present these cases say that they would prefer, in the first case, for their daughter to have the merely unpleasant operation on the 29th, and, in the second case, for their daughter to have had the painful operation on the 27th,” writes MIT philosopher Caspar Hare. “Furthermore, in each case they feel that it makes sense to have the preference, given the way in which it is appropriate to care about a daughter. While they would be loath to condemn a parent with different preferences, they feel that such a parent would be making a kind of mistake.” Why should this be?

If aliens watched us play golf, what on earth would they think we were doing? We invent an arbitrary, difficult task and then try to perform it, expending vast quantities of money and leisure time in a pursuit that serves no productive purpose and that most players find frustrating. A writer for Punch summed it up in 1892: “The object is to put a very small ball into a very tiny and remotely distant hole, with engines singularly ill adapted for the purpose.”

In other pursuits, if people deliberately impede themselves from achieving their own goals, we question their rationality. But this is almost the whole point of golf — rules and courses are deliberately designed to make it extremely difficult to get the ball into the hole (a strange goal to pursue in the first place).

“The intuitive explanation, of course, is that golf wouldn’t be worth playing if it were easy,” writes Washington State University philosopher David Shier. “It simply wouldn’t be fun. Well, maybe much of the time it’s not exactly fun anyway, but it surely wouldn’t be interesting, and it wouldn’t ever be gratifying. Golfers place obstacles in the way of achieving their own goals in order to make the sport more challenging and, consequently, more interesting and enjoyable.” … But why pursue it at all?

In 1984, a diver was working in the beluga whale enclosure at San Diego’s National Marine Mammal Foundation when someone shouted “Out, out, out!” On emerging, the diver asked who had told him to exit the tank, and it turned out that the speaker was the whale itself, Noc, who had lived at the facility since his capture in 1977.

Noc’s keepers had previously heard strange sounds coming from the whale and dolphin enclosure that seemed to resemble people talking in the distance, their words just beyond the limit of comprehension. “We were sceptical at first,” neurobiologist Sam Ridgway told New Scientist. “They were definitely unlike usual sounds for a [beluga], and similar to human voices in rhythm and acoustic spectrum.”

The researchers concluded that he was indeed mimicking human speech, though Noc used his nasal tract to produce sounds, rather than a larynx, as humans do. They had only a short window in which to study the behavior: After four years Noc stopped, either because he’d reached maturity or because he’d lost interest.

Anthropologist Georges Vacher de Lapouge turned up a surprise in 1890: While excavating a Bronze Age cemetery at Castelnau, near Montpellier, France, he discovered three apparently human bones of gigantic size. On the left is the “giant’s” femur, or thigh bone; on the right is a tibia, or shin bone. Between them is a normal humerus, or upper arm bone, from the same cemetery. At the bottom is a fragment that may belong to either a femur or a humerus; if it’s the latter then it must have belonged to the same giant. If this is right, then the individual would have stood between 10 and 11 feet tall.

Lapouge published his discovery in La Nature that year. “I think it unnecessary to note that these bones are undeniably human, despite their enormous size,” he wrote. “The volumes of the bones were more than double the normal pieces to which they correspond.”

The specimens were examined by zoologists and paleontologists at the University of Montpellier and passed eventually to pathological anatomist Paul Kiener of the Montpellier School of Medicine; the London Globe noted that “Kieger, who, while admitting that the bones are those of a very tall race, nevertheless finds them abnormal in dimensions and apparently of morbid growth.”

“There has been an old tradition among the peasants of the vicinity that a cavern in the valley was, in olden times, occupied by a giant,” noted Popular Science News. “It would be curious if the discovery of M. Lapouge should show it to be founded on fact.”

Interestingly, the bones of further French giants were reported to have turned up near the same location a few years later. From the Princeton Union, Oct. 11, 1894: “In a prehistoric cemetery recently uncovered at Montpellier, France, while workmen were excavating a waterworks reservoir, human skulls were found measuring 28, 31 and 32 inches in circumference. The bones which were found with the skulls were also of gigantic proportions. These relics were sent to the Paris academy, and a learned ‘savant’ who lectured on the find says that they belonged to a race of men between ten and fifteen feet in height.”

But that seems to be the end of it. Was the whole thing a hoax?

During the Great Depression, Babson College founder Roger Babson commissioned unemployed stonecutters to carve inspiring inscriptions on 25 boulders in Dogtown, an abandoned settlement in Gloucester, Massachusetts:

• COURAGE
• IDEAS
• HELP MOTHER
• KINDNESS
• LOYALTY
• IF WORK STOPS, VALUES DECAY
• BE ON TIME
• GET A JOB
• INDUSTRY
• INITIATIVE
• INTEGRITY
• KEEP OUT OF DEBT
• SAVE
• SPIRITUAL POWER
• STUDY
• TRUTH
• WORK
• BE CLEAN
• BE TRUE
• PROSPERITY FOLLOWS SERVICE
• USE YOUR HEAD
• IDEALS
• INTELLIGENCE
• NEVER TRY/NEVER WIN

Babson did some of the work himself. “Another thing I have been doing, which I hope will be carried on after my death, is the carving of mottoes on the boulders at Dogtown, Gloucester, Massachusetts,” he wrote in 1935. “My family says that I am defacing the boulders and disgracing the family with these inscriptions, but the work gives me a lot of satisfaction, fresh air, exercise and sunshine. I am really trying to write a simple book with words carved in stone instead of printed paper. Besides, when on Dogtown common, I revert to a boyhood which I once enjoyed when driving cows there many years ago.”

The boulders are extant today and can be visited on a hiking trail.
