Population III stars were, until recently, a hypothetical class of stars that were presumed to be the very first generation of stars formed after the Big Bang. Because they were formed when the Big Bang was still so recent that the interstellar medium was still very warm, and universe was still essentially devoid of any element heavier than helium or lithium, these stars can be much larger and more massive than any star formed more recently, and have some unusual behavior and physical properties.
It is hypothetical no longer. Apparently supernovae with characteristics indicating it’s progenitor star were massive population III stars have been found,

Apparently the first direct observation of a population III star has been made.
Population III stars were the hitherto merely hypothesized very first stars to ever form after the Big Bang. they have unusual properties that reflect the extreme youth of universe at the time of their formation. They were instrumental in rapidly kicking off the process of creating heavier elements for the universe that made the world and universe as we know it now possible.
Finding population III Star has been, next to finding extra-solar planets, one of the holy grail of observational astronomy for decades.

117 billion homo sapiens had been born since our species first arouse in Africa 200,000 years ago.
of these 7% are currently living.

Maxime Weygand, the french general who read the conditions of the 1918 armistice to the german delegation in a railway car in Compiegne, died only in 1965 at the age of 98 in Paris. He replaced Maurice Gamelin as CinC of the french army after Gamelin failed to stop the german army in May 1940. Weygand failed as well. Gamelin became CinC in the 30s, succeeding.....Weygand, but was heavily impaired in his ability to fulfill this role by suffering from an advanced stage of Syphilis.

The 369th Infantry Regiment was a largely African American infantry unit, variously known as the Harlem Hellfighters, the Men of Bronze, and the Black Rattlers. In WWI, the unit spent 191 days in front line trenches, more than any other American unit, suffered the most casualties (1500+), and was the first American unit to cross the Rhine into Germany.

Violet Jessop was stewardess and nurse employed by the white star line. She was present at, and survived, the sinking of both the Titanic and Britannic, titanic sister ship. Thus she was the only person to be present at sinking of both the largest passenger ship lost in peacetime, the titanic,, and the sinking of the largest passenger ship lost in time of war, the Britannic.
Titanic and Britannic had a third, luckier sister ship, the Olympic. Olympic didn’t sink, but she was involved in a serious accident when she was accidentally rammed by a Royal Navy Cruiser. Yes, Violet Jessop was aboard the Olympic at the time of that accident as well.
When the titanic sank, Violet Jessop was ordered into Lifeboat 16, and given an baby to keep safe. When life boat 16 was rescued, an unknown woman grabbed the baby from her arms and ran off crying. Violet Jessop assumed the woman was the baby’s mother but never found out who the baby or woman were. 42 years later, after she had retired “to be as far away from the sea as possible”, she received a phone call in the middle of the night, inquiring if she was the Violet Jessop of white star line who had saved a baby. She replied that she was. The person on the other end laughed, said she was that baby, and hung up. When violet Jessop recounted this story to her biographer, her biographer suggested it might be children in her neighborhood playing a prank. Violet replied she had never told the tail of the baby she rescued to anyone before,

Interestingly, most fishes move their pectoral and pelvic fins in the same manner when swimming.

In 1920, American actress/playwright Ruth Gordon checked herself into a Chicago hospital to have her legs broken and straightened to cure her bowleggedness.

(This post was last modified: June 11, 2023 at 1:21 pm by Anomalocaris.)
even though 20,000 soldiers on both sides died during the battle of waterloo in 1815, only one skeleton of the battle dead had ever been found.
It is believed the local and English entrepreneurs had collected all the corpses and bones they could find, and ground them into fertilizers during the week and months after the battle.
The notion of hallowed ground and war graves were not much of the thing then.
