TIL that the longest running lab experiment is the Pitch Drop experiment. It demonstrates how tar is the most viscous liquid being 100 billion times more viscous than water. Only 9 drops have fallen in the 95 years since it began in 1927.

@aetherczar shared a TIL about Tar being one of the most viscous substance, and I wondered about Glass and found the above... Sharing due to Medieval Windows defying conventional wisdom. Unless they want to speculate that perhaps a miracle is occurring?

Glass viscosity calculations definitively debunk the myth of observable flow in medieval windows - The American Ceramic Society
Glass scientists have taken a closer look at the urban legend of glass flow in medieval windows—combining theory and experimental techniques, the results definitely bust the myth and indicate the highest ever direct measurement of glass viscosity at low temperatures.

Counterpoint from someone largely on the same 'side'. Ignore the invective in favor of the info.

While we're on the subject of miracles, here's an amazing story that is hard to explain otherwise.

A Stanford Professor who challenged the orthodoxy of lockdowns has warned that “academic freedom is dead,” and that all those who have stood up to the regime narrative now face “a deeply hostile work environment.”

Ozymandias was one of the Greek names of Rameses II (1301-1234 B. C.).
-Percy Shelley's most famous
poem 1818-
"Ozymandias" famously
describes a ruined statue of an ancient king in an empty
desert. Although the king's
statue boastfully commands
onlookers to "Look on my
Works, ye Mighty, and despair," there are no works left to examine: the king's cities, empire, and power have all disappeared over time.
In this poem Shelley describes
the broken statue and reflects
upon the impermanence of
earthly things. The king, once
powerful, is no more. His relic,
the statue, is broken to pieces
and will soon crumble to dust.
Why do you think people build
statues?
What is the point of having a
statue of YOURSELF made?
Why do you think leaders of
countries or empires used to
have statues made of them?

The House-of-Wisdom contained so many books that the Tigris River turned black from the ink when all of them were destroyed
-Part 1-
Back in the 9th century AD, the House of Wisdom was established in Baghdad.
It contained manunoscripts on mathematics, astronomy, science, medicine, and philosophy from Persia, India, and Greece. There were also astronomical observatories, laboratories for chemistry and alchemy, and a center for studying science.
Everyone had access to it and everyone could be schooled there. The library and its work were supported by everyone, including merchants and the military. 👇

Hulagu Khan's Army Threw So Many Books into the Tigris River that they Formed a Bridge that Would Support a Man on Horseback
-Part 2-
-13 February 1258-
Baghdad, then a city of 1
million, falls to the Mongols as the Abbasid Caliphate is destroyed, ending the Golden Age. Baghdad, founded in the 8th by Abbasid Al-Mansur, was a hub of learning & commerce during that Golden Age.
1258 under the command of Hulagu Khan sacked Baghdad, destroying the House of Wisdom, the leading library in the leading intellectual center of the Arab.
It was the greatest repository of books in the world and had become one of the greatest hubs of intellectual activity in the Middle Ages, attracting the most brilliant Arab and Persian minds.
Would you consider this incident to be the biggest calamity in human history?

Americans eat 704 million pounds of turkey every Thanksgiving.
According to the National Turkey Federation, around 44 million turkeys were served at Thanksgiving in the United States in 2017. That's compared to 22 million pounds at Christmas and 19 million at Easter. The average weight of each, meanwhile, was 16 pounds, which means we're gobbling up 704 million pounds of turkey across the country.
