How Eratosthenes calculated earth's circumference more than 2000 years ago [🎞️ GeoQuest]

It's insane to even think about them achieving such feats. There was no Internet, barely any books to learn from all they had was time to really think about stuff. Genious.

“Unlock the secrets of reality! Discover how mathematics reveals the hidden world of complete rational abstraction –Discover how Pythagoras’ 'Music of the Spheres' evolves into the current scientific theory known as String Theory.” (Book IV The Cosmic Symphony)

A stick, shadow and sheer genius to measure the circumference, no satellites required in this method. He realized that the Sun doesn't lie.

The power of math!

people knew that the earth was round 2000 years ago and yet there are still idiots who believe the earth is flat or whatever bulshit

Oh stop it , idiots ! The Earth is flat ! 😉

Bro was a chad 🤞

Humans are really rational even with limited technology

Ancient GPS, anyone? 🌍📐 Testing a theory: Could Eratosthenes have used his method to calculate the circumference of Mars if he had a Martian shadow stick? #GeoQuest #AncientTech

Eratosthenes proved that curiosity and observation can unlock the universe's secrets. 🌌

We do not live on a spinning ball.
