Just got to explain to some high school students how Eratosthenes "proved" the Earth is round and measured its size - under the assumption the rays from the distant sun are parallel.
But the result is ALSO consistent with a flat Earth and the sun a few thousand miles away.
Two diametrically opposed interpretations can explain the same experimental results. You have to be very careful what hidden premises you accept.

TIL about the uncanny valley. The concepts suggests that humanoid objects that imperfectly resemble actual human beings provoke uncanny feelings of uneasiness and revulsion in observers.

“A general dissolution of principles and manners will more surely overthrow the liberties of America than the whole force of the common enemy. While the people are virtuous they cannot be subdued; but when once they lose their virtue then will be ready to surrender their liberties to the first external or internal invader.”

The Swedish Ship Götheborg entering London, in amazing style with a full entrance from the famous Tower Bridge! 😮👏 The Swedish Ship Götheborg is the world’s largest operational wooden sailing ship and a unique replica of an 18th century Swedish East India Company ship that sank outside of Gothenburg in 1745. 🚢

The Mediterranean used to be dry.
The Mediterranean used to be a dry basin until some five million years ago during the Zanclean flood—in which water from the Atlantic poured through the Strait of Gibraltar and filled the basin. Theories abound as to how this happened, but one catastrophic interpretation has the basin filling up in only two years, thanks to a massive torrent of water.

The murder, the trial of Leo Frank, and his lynching has deeply affected the lives of all involved. All the principals in the trial are dead now—and the obituary of each of them mentioned their connection to the murder of little Mary Phagan.
My family had hoped that the lynching of Leo Frank would be the final ending of the horrible tragedy; that they could finally continue their lives; that the pain would ease.
It hasn't.

This graphic record from the imperial war museum's collections depicts the moment the guns fell silent on the western front.
It reveals fighting continued right up until the final moments of the First World War, with artillery still visibly active at 10.58am.
Then bird song can be heard on the Western front.

On the uncanny valley... Why are we hardwire programmed to viscerally fear and despise that which is only almost human?
Every human culture has believed in the existence of other beings, monstrous humanoids, sapient but inhuman. They have gone by different names: boogeymen, bugbear, cyclopes, giant, jotun, ogre, oni, troll, yeti, and more. But they are always feared, lurkers in the shadows, threats to the clan, tribe, or hearth. Dungeons & Dragons didn’t create these monsters, and (despite ongoing controversies) they don’t represent anything modern. Humanity’s legendary heroes have been fighting these monsters since time immemorial.
The real question is why — why does every civilization have similar myths? Why does every culture have legends of monstrous humanoids, and why are they are always depicted as fearsome and dangerous?
Because the legends were real. The orcs were real.
