In this episode, I tell the story of Eratosthenes, a Greek scholar who, more than two thousand years ago, calculated the Earth’s circumference with amazing precision. No GPS, no satellites, no computers. Just a stick, a brilliant mind, and deep curiosity. A true lesson in science, reasoning, and observation.#Eratosthenes #HistoryOfScience #EducationalPodcast #Curiosity #AncientGreece #Science #Astronomy #MathematicsIf you’d like to support this podcast, you can do so at ko-fi.com/juansweden.
