There’s a funny story at the beginning of this video.
Thales was a natural scientist and the founder of trigonometry. He lived around 600 BC.
He was gazing at the stars and he fell in a well.
He got mocked for it. Something like this:
“Like, if you are so smart, why don’t you get rich? Haha.”
So he did. lol. He applied math to oil production, made a bunch of money and then gave it all away. He was a good businessman but he was really inspired by logos.
