Today I learnt

This is a list of superficial but interesting facts I've come across. I've tried my best to verify these but some of them might be a better story than fact.

  • 2024-01-20: Up until the early 20th century the swiss had a national health crisis of goetre. In 1921, nearly 30 per cent of 19-year-old Swiss conscripts had a goitre. In the cantons of Luzern and Obwalden, one in four men were exempt from military service as a result of goitres so large they struggled to breathe. For every man with a goitre, three women suffered from the condition. Goetres are caused by a lack of Iodine. And switzerland's soil uniquely lacks iodine. This is because in the last ice age, a permanent ice sheet formed over the Alps. Up to one kilometre thick. It thawed and refroze in stages, and with every thaw, meltwater washed out the rubble. Over the course of 100,000 years, this ice sheet tore the top 250 metres of rock and soil from the surface of the Swiss Central Plateau removing it's iodine.
  • 2023-12-09: Some consider the first "Cyber attack" to have taken place in 1834. The Blanc brothers in France traded government bonds in Bordeaux, where information about market movements took several days to arrive from Paris by mail coach. If you could get the information sooner you could beat the market and make money, though no faster method existed, except for a visual semaphore network of towers that the government had setup. They bribed a tower operator in Paris to encode messages by adding spurious characters followed by a delete symbol. Depending on the character they'd know the direction of the market. They were finally caught in 1836 but were not convicted because there was no law against misuse of data networks.
  • 2023-11-23: In 1750 BCE you'd need to work ~50 hours for one hour of lamp light. Now less than a second will buy you an hour of light.

Vast amounts of supplies were air dropped, which meant drastic changes to the lifestyle of the islanders. Cult members worshiped certain unspecified Americans having the name "John Frum" or "Tom Navy" who they claimed had brought cargo to their island during World War II and whom they identified as being the spiritual entity who would provide cargo to them in the future. In attempts to get cargo to fall by parachute or land in planes or ships again, islanders imitated the same practices they had seen the military personnel use. Cult behaviors usually involved mimicking the day-to-day activities and dress styles of US soldiers, such as performing parade ground drills with wooden or salvaged rifles. In a form of sympathetic magic, many built life-size replicas of airplanes out of straw and cut new military-style landing strips out of the jungle, hoping to attract more airplanes.

  • 2023-04-07: There are whales alive today that were born before Moby Dick was written. Bowhead whales are considered to be the longest-living mammals, living for over 200 years. In May 2007, a 15 m (49 ft) specimen caught off the Alaskan coast was discovered with the 90 mm (3.5 in) head of an explosive bomb lance of a model manufactured between 1879 and 1885, so the whale was probably bomb lanced sometime between those years, and its age at the time of death was estimated at between 115 and 130 years. Spurred by this discovery, scientists measured the ages of other bowhead whales; one specimen was estimated to be 211 years old.
  • 2023-03-18: A coal mine fire has been burning beneath the town of Centralia Pennsylvania since 1962. The town's population has declined from 1,000 in 1980 to five residents in 2020.

  • 2022-05-14: Early Greek & Latin texts employed "Scriptio continua", which is the style of writing without punctuation or spaces. Usually texts were read as performance pieces and so quick parsing wasn't concern. The reader had the liberty to insert pauses and dictate tone, making the act of reading a significantly more subjective activity than it is today. However, the lack of spacing also led to some ambiguity because a minor discrepancy in word parsing could give the text a different meaning. For example, a phrase written in scriptio continua as collectamexiliopubem may be interpreted as collectam ex Ilio pubem, meaning "a people gathered from Troy", or collectam exilio pubem, "a people gathered for exile". Thus, readers had to be much more cognisant of the context to which the text referred. Later, this evolved to “boustrophedon”, which included lines written in alternating directions.

Then, when the company managed to renegotiate, there was so much five-cent price advertising and so many vending machines that only accepted nickels that it took another couple of decades before Coca-Cola could break the nickel’s spell. Since then Arizona Ice tea have maintained there 99c price for 30 years. Side note the Arizona ice-tea founders had never stepped foot in Arizona when launching the brand.
  • 2022-04-08: The Lobster War was a dispute over spiny lobsters that occurred from 1961 to 1963 between Brazil and France. The Brazilian government refused to allow French fishing vessels to catch spiny lobsters 160 km off Brazil's northeastern coast by arguing that lobsters "crawl along the continental shelf." However, the French maintained that "lobsters swim" and so they could be caught by any fishing vessel from any country. The situation became very tense once the French rejected that demand and radioed a message asking for the French government to send a destroyer to accompany the lobster boats, which prompted the Brazilian government to put its many ships on a state of alert. The dispute was resolved unilaterally by Brazil, which extended its territorial waters to a 370 km zone and took in the disputed lobsters' bed.

  • 2022-01-06: Goose egg addling is a wildlife management method of population control for Canada geese and other bird species. The process of addling involves temporarily removing fertilized eggs from the nest, testing for embryo development, terminating embryo development, and placing the egg back in the nest. Returning the egg to the nest misleads the goose into believing the egg is still developing. Otherwise, the goose would begin laying again. Goose egg addling was predominantly used in the aftermath of the plane crash of US Airways Flight 1549 on January 15, 2009. Following an investigation by officials, which determined the plane crash was caused by a bird strike of Canada geese, an estimated 1,739 goose eggs were coated with oil in an effort to prevent any similar incidents from occurring. There is an interesting document which details all you need to know about addling. From defending oneself from the geese with umbrellas and trash cans, the float test to determine if the embryo is fertilized to alternate termination strategies to oiling method like using dummy eggs.
  • 2021-12-27: The Gospel of Matthew is the only one of the four canonical gospels to mention the Magi (aka the Three wise men). The gospel never mentions the number of Magi.

There are other biases for example: some categories regarding women were adjacent to categories on etiquette and in 1932 topics relating to homosexuality were first added to the system under 132 (mental derangements) and 159.9 (abnormal psychology). In 1996, homosexuality was added to 306.7 (sexual relations); this remains the preferred location in the current edition.
