Determining the circumference of the Earth

Explanation:

Eratosthenes was an Ancient Greek mathematician and geographer who is notable for determining the circumference of the Earth using geometry. By measuring the sun’s angles from two separate places at the same time, on the same day, he was able to determine that the circumference of the Earth was around 46,000 km. Modern conclusions show that he was only off by a few hundred kilometers, a remarkable achievement for the third century BCE.
