The length of a day on Mars -- the time it takes Mars to complete a rotation on its axis -- has been known since 1666. It was even accurate to within 3 minutes!
The length of a day on Saturn was a mystery until 2019.
It was extremely difficult to measure for two reasons. First, because without a solid surface, Saturn had no geographical features by which to measure rotational speed. And Saturn has a funky magnetic field that makes alternative ways of measuring hard. Saturn's day was only measured when NASA's Cassini probe studied the planet's icy, rocky rings and their interaction with the planet.
On Nov. 5, 1996, (which was Election Day for the presidency of the United States) the popular New York Times crossword puzzle included a surprising clue:
39 [Across]. Lead story in tomorrow’s newspaper (!), with 43 [Across]
The answer for 43 Across was ELECTED. But which presidential candidate fit in 39 Across -- and presumably was the winner of the presidential election? In fact there was not one answer but two. Rather than predict the outcome of the election, the writer of the crossword had managed to make it possible for CLINTON to work and for BOBDOLE to work, by changing the answers to the respective seven down clues. You can read the full crossword here.
A recent study of the area in the Maya city of Tikal has found an unusual complex of buildings, which seems to be similar to the citadel of Teotihuacan. Tikal is in northern Guatemala, and Teotihuacan is central Mexico about 600 miles to the north. Inside the complex in Tikal were found weapons in a Teotihuacan style, including ones made from green obsidian from central Mexico, incense burners, carvings of Teotihuacan's rain god, and a burial in a pyramid with offerings similar to offerings in Teotihuacan burials. Ceramics within the pyramid have been dated to around 300 CE.
Interestingly, an elite Maya compound has been discovered in Teotihuacan, with its murals smashed and buried. Was this site the corresponding Tikal embassy to Teotihuacan, the partner of Teotihuacan's embassy complex in Tikal? The two cities had a difficulty relationship: Teotihuacan invaded Tikal in 378 CE.
This blog has been going for almost 10 years now. It has expanded from a tumblr blog to include this website, a ko-fi, and a patreon. And it has always remained a one-person show. Historical-nonfiction is, frankly, a lot of time and effort. You ongoing support has allowed me to continue for this long. But the time has come for me to take a step back from historical-nonfiction.
What does this mean for you? You can still look forward to learning something interesting, something historical, something to expand your knowledge of world. But posts will come when inspiration strikes, not on a fixed schedule as it has been. In short: what this means for the future is historical-nonfiction will have fewer new posts.
I want to finish this small announcement by saying thank you all. For everything.
The bronze jar is only about 5cm across. And inside is a tiny amount of face cream -- or what was once face cream. It was excavated in 2017 at the Liujiawa site in China, which was the capital of Rui, a minor state during the early Spring and Autumn period (circa 700 BCE).
The Meteor Crater (yes, that is it's actual name) is one of the best preserved meteor craters in the world. This is due to its young age for a crater, at approximately 50,000 years old, and the dry climate around it in Arizona.
That is not to say the Meteor Crater is perfectly preserved. Scientists estimate that 50–65 ft (15–20 m) of height has been lost at the rim crest as a result of natural erosion, and 100 ft (30 m) of sediment has been added to the basin.
Mad, Bad, and Potentially Dangerous to Ancient Monuments
Inscribed on the Temple of Poseidon at Cape Sounion, southeast of Athens, is the name BYRON. It is possible that the English poet Lord Byron carved it during his first visit to Greece at age 22, before he became famous. He later wrote:
Place me on Sunium’s marbled steep,
Where nothing, save the waves and I,
May hear our mutual murmurs sweep …
But despite all that, there remains no definitive answer as to whether Byron carved it himself, or a fan of his poetry thought to add his name there.
An Aztec creation myth states that there were four failed attempts to create humans who would survive. It was only on the fifth attempt, when humans began to eat corn, that they were able to propogate themselves and continue as a species.
