Over 2,000 years ago Eratosthenes, the ancient Greek scholar, measured the Earth's circumference with just a stick, sunlight and simple math
Ancient Greek scholar Eratosthenes calculated Earth's circumference using sunlight and geometry. He observed shadows in Syene and Alexandria to determine the planet's size. His experiment revealed the Earth was not flat, which was a significant discovery. Eratosthenes' calculation of 252,000 stadia closely matched modern measurements. This achievement demonstrates how curiosity and logic can lead to groundbreaking scientific insights.
