Over 2,000 years ago, Eratosthenes proved the Earth was round and measured it using only shadows and basic math. On the summer solstice, he noticed that while objects cast shadows in Alexandria, they didn’t in Syene. That tiny clue unlocked the secret of Earth’s size: 40,000 km, nearly perfect by modern standards. His work survived despite the tragic loss of the Library of Alexandria, while Ptolemy’s later miscalculations led Columbus astray. | History Revived
