In this project, students will explore the fascinating life and work of Eratosthenes, a renowned Greek scholar who excelled in multiple fields, including mathematics, geography, poetry, astronomy, and music theory. Specifically, they will delve into one of his most famous experiments, where he managed to calculate the circumference of the Earth. By studying his methods, students will then have the opportunity to recreate the experiment themselves in the equinox of March, 2024.
