Educational Video from NASA: Looking Down a Well: A Brief History of Geodesy

If you don't know what geodesy is, you will after you watch this short and informative video from NASA. It's helped give us a lot of information about the Earth!

Geodesy is a field of study that deals with the measurement and representation of the Earth, and it all started when a clever human named Eratosthenes discovered that you could measure the circumference of the Earth by looking down a well. Over time, the field of geodesy has expanded and evolved dramatically, and NASA uses technology like radio telescopes, ground surveys, and satellites to contribute! Learn more about geodesy in this video!
