These compounds are named housane, churchane, basketane, and penguinone.
Below: To celebrate the 2012 London Olympics, chemists Graham Richards and Antony Williams offered a molecule of five rings. They called it olympicene.

Travel Broadens the Mind
In 1971, physicist Joseph C. Hafele and astronomer Richard E. Keating bought airline tickets for a party of four to circle the world twice on commercial airliners. Each party consisted of Hafele, Keating, and two passengers named “Mr. Clock.”
The guests were cesium-beam atomic clocks. The researchers chaperoned the timepieces once eastward around the world and once westward. Then they compared the traveling clocks with one that had remained at the United States Naval Observatory.
The results were published in Science the following year. The clocks had been found to disagree, demonstrating the effects of kinematic and gravitational time dilation.
The total cost of the effort was $8,000. It’s been called one of the most inexpensive tests ever conducted of Einstein’s relativity.
It Begins
Cockatoos in Sydney have mastered a five-step process for opening the lids of trash bins to reach the food inside.
“It was so exciting to observe such an ingenious and innovative way to access a food resource, we knew immediately that we had to systematically study this unique foraging behavior,” wrote behavioral ecologist Barbara Klump.
The birds learn the technique from one another, and cockatoos in different regions have worked out different techniques. Before 2018, the behavior had been reported in only three suburbs, but by the end of 2019 the number had reached 44.
“These results show the animals really learned the behavior from other cockatoos in their vicinity,” Klump wrote.

Problem Solved
In 1991, botanist John L. Strother was reviewing the classification of North American sunflowers when he identified a new genus. By this time his 100-page monograph was in the final stages of proofing, and adding a new entry in the middle would require troublesome changes in the layout.
The genera were listed alphabetically, and the last one was Zexmenia. So Strother named the new genus Zyzyxia. Since this placed the new entry near the end of the article, it minimized the necessary changes, and the editor accepted the addition.
Skylon
A striking symbol of the 1951 Festival of Britain was this cigar-shaped sculpture, which seemed to float impossibly 15 meters above the ground.
Designed by Hidalgo Moya, Philip Powell, and Felix Samuely, the structure relied on the principle of tensegrity: The base rested at the junction of three tensioned cables, and three further cables held the body vertical. Together, these six well-positioned supports were enough to keep the 80-meter sculpture from toppling.
Britons joked that, like the national economy at the time, it had “no visible means of support.”
Fieldwork
On Oct. 24 [1947] two University of Chicago students rattled into Reno., Nev. in a Model-A Ford to try the gambling. Their total resources: $100. Wasting no time, they went to the Palace Club, where they studiously made a chart of the recurrence of numbers on the roulette wheel. Then they went into action. Playing number 9, which their records indicated as the best possibility, they parlayed their $100 into $5,000 in 40 hours. At this point the manager became uneasy, switched the wheel. So the students moved on to Harold’s Club.
There they used the same system. Sure enough, their $5,000 rose to $14,500. But then, unaccountably, their system went sour. They dropped from $14,500 to $10,000 and kept going down. That was when the young theoreticians made the smartest move of all. They pocketed their winnings, packed up the Model-A and went home, ahead by $6,500.
(The students were Albert Hibbs and Roy Walford. Accounts vary as to their total takings; Hibbs claimed $12,000 on You Bet Your Life in 1959. They spent a year sailing around the Caribbean and then returned to their studies. Hibbs went on to become a JPL physicist and Walford a UCLA pathologist.)
Podcast Episode 351: Notes and Queries
In this week’s episode of the Futility Closet podcast we’ll explore some curiosities and unanswered questions from Greg’s research, including a novelist’s ashes, some bathing fairies, the mists of Dartmoor, and a ballooning leopard.
We’ll also revisit the Somerton man and puzzle over an armed traveler.
Ventriloquism
On September 19, 1968, as the Soviet Union’s Zond 5 spacecraft was circling the moon, Jodrell Bank Observatory and the CIA were shocked to intercept the voices of cosmonauts Valery Bykovsky, Vitaly Sevastyanov and Pavel Popovich reading out telemetry and computer data and even discussing the prospect of a landing. The Zond mission had been thought to be uncrewed; now it sounded as though the Soviets might beat the United States to a moon landing. Apollo 17 astronaut Eugene Cernan said that the incident “shocked the hell out of us.”
It was a hoax. Popovich recalled later, “When we realized we would never make it to the moon, we decided to engage in a little bit of hooliganism. We asked our engineers to link the on-the-probe receiver to the transmitter with a jumper wire. Moon flight missions were then controlled from a command centre in Yevpatoria, in the Crimea. When the probe was on its path round the Moon, I was at the center. So I took the mike and said: ‘The flight is proceeding according to normal; we’re approaching the surface …’ Seconds later my report — as if from outer space — was received on Earth, including [by] the Americans. The U.S. space advisor Frank Borman got a phone call from President [Johnson], who asked: ‘Why is Popovich reporting from the moon?’ My joke caused real turmoil.
“In about a month’s time. Frank came to the USSR, and I was instructed to meet him at the airport. Hardly had he walked out of his plane when he shook his fist at me and said: ‘Hey, you, space hooligan!'”
