The neurodivergent experience is talking about your brain as if it's a separate entity from your self

is there a problem with a romance between two masked gentlemanly thieves in Victorian England?

Ok so this is cool but I always wondered how they knew the shadows were different at the same instant. I mean it is not like they had phones. How did they sync up that instant. I feel like that would be interesting to know but no one ever says.

^^^Does anybody know this one? How, that far apart, the time at which the shadows were observed was synced up? I am genuinely curious, not a goddamn moron asking a gotcha question. High/Low tide? (I live in the middle of the country I do not know for the precise habits of tidal activity.) The appearance of a star (or planet) in the sky? Something as utterly mundane as sunrise?

ANSWER EVEN COOLER THAN I HOPED!!

Eratosthenes’ work was thorough enough that by the time he finished revising his calculations, he ended up only 66 km off of the actual polar circumference of the Earth, or an error margin of 0.16%. [wiki]
