Information flows through the internet at speeds so fast that, if you literally blink, you'll miss it. Outlets like political Twitter timelines, science blogs, and YouTube channels dedicated to world history, have made it their mission to share the most interesting facts on a variety of topics. Even with those sources, you might have missed some things. Don't worry. Reddit's got your back, thanks to a question asked by user, r/Taully12:
Reddit, what is the most 'mind boggling' fact you know?
In World War 2, a Hungarian Mathematician named Abraham Wald developed a counter-intuitive method for armor plate placement while studying damaged aircraft. He observed planes returning home from sorties with large holes in them, and was tasked with figuring out where to put armor plates. His crucial insight was to not put armor plates where the holes were.
The holes in the aircraft that returned represented damage that did not impact the ability of the planes to return home. In other words, he made the critical observation of the bias in the data he was observing: he was only looking at planes that survived. With this knowledge, he instructed armor to be placed in areas that were not damaged, because if these areas were hit, there would be no damage in that component in the planes that returned home.
The inscription on the One Ring from Lord Of The Rings is not actually "Elvish" which quite a few people mistake it to be, but an entirely different language that Tolkien created called The Black Speech of Mordor or "Orcish".
Tolkien has stated that he came up with the Black Speech by thinking of the most horrible things in his life. In particular his experiences from WW1, which is why when you hear The Black Speech, such as when Sauron speaks it in LOTR & The Hobbit, it sounds like a dialect sent straight from hell.
He grew to be disgusted by the language he created so much that when a fan sent him a wine goblet with The One Ring's inscription on it as a gift, he used it as an ashtray.
