In 240 BCE, Greek mathematician Eratosthenes set out on an epic journey to calculate the Earth's circumference. Armed with his knowledge of trigonometry and geometry, Eratosthenes used the angle of the sun's rays and the distance between Alexandria and Syene to accurately determine the size of the Earth. This method revolutionized geography and inspired generations of mathematicians and scientists to follow in his footsteps. In this video, we take a closer look at Eratosthenes' groundbreaking calculation, exploring the history of mathematics and the scientific revolution that followed. Join us as we delve into the world of ancient science and mathematical innovation, and uncover the accuracy and importance of Eratosthenes' calculations.
