people today with access to more raw information than any other period: the earth is flat

german artilleryman in 1916, who barely washes his own ass: I need to account for the curvature and rotation of the earth when plotting my firing plans

Eratosthenes, an Egyptian, in 3750 BC when fucking mammoths hadn’t even gone extinct yet: Oh hey I can use these two obelisks to calculate the earth’s entire circumference based on the length of their shadows and the Earth’s curvature. Neat.
