Eratosthenes was an ancient Greek mathematician who calculated the Earth's circumference over 2,000 years ago. On the summer solstice, he measured the angle of a shadow in Alexandria, where it was about 7 degrees, while no shadow was cast in Syene. By determining the distance between the two cities and using basic geometry, he estimated the Earth's circumference to be around 40,000 kilometers, which is remarkably close to the modern measurement of 40,030 kilometers.

And it has Carl Sagan in it. The video doesn’t just demonstrate a science fact, but how critical thinking works, asking why and how, then design a way to test if something is true,

✦ @booksociety​’s To the Stars event: The Martian by Andy Weir LOG ENTRY: SOL 475 I’m in trouble. I watched two Phobos transits yesterday and sighted Deneb last night. I worked out my location as accurately as I could, and it wasn’t what I wanted to see. As far as I can tell, I hit Marth Crater dead-on. Craaaaap. I can go north or south. One of them will probably be better than the other, because it’ll be a shorter path around the crater. I figured I should put at least a little effort into figuring out which direction was best, so I took a little walk this morning. It was over a kilometer to the peak of the rim. That’s the sort of walk people do on Earth without thinking twice, but in an EVA suit it’s an ordeal. I can’t wait till I have grandchildren.
