Hey. I saw this below about the power of math to tell you things not happening in your presence, and it was totally mind-blowing, I thought I must share.
2200 years ago, Eratosthenes estimated the Earth’s circumference using math without ever leaving Egypt. He was remarkably accurate. Christopher Columbus later studied him.
Bonus fact: Birds are dinosaurs.
Do some research, and tell us if you agree or not.
Mind blowing!
Incredible!
