I love that Eratosthenes was able to estimate the circumference of the earth with the amount of math we had in his era. Meanwhile, modern flat-earthers are still making me want to vomit.
I used to see fractals in the shadows on LSD. I couldn’t think of the word “fractal,” and told my friend, “You know, that thing in math?” And he said to me, “When you trip you see math?!” Fun times. To be a teen again.
