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,

School is stupid, parents with unrealistically high expectations of you are stupid, teachers who overwork you are stupid.
You don't need their approval. You don't need to impress authority to have worth.
You don't need to be perfect, especially not in a broken system.
Test scores aren't a measure of intelligence. You are smart, even if the material was difficult to grasp.
You're not "wasting your potential" if you decide to pursue a career you love. Create art, write music, perform, you're contributing to the beauty of the world. There's more value in that than most people see.
You're not "wasting your potential" if you're an adult who isn't busting their butt in college or a fancy job. The economy is fucked right now, and being an adult is hard. You're doing your best.
And sometimes, you can't be at your best all the time, but you're trying, and that's all that matters.
Just learn. Learn and love learning. Learn without school holding you down. Find your passions, and run after them. Pursue knowledge because it's fucking fun.
Research something you care about for fun, challenge yourself to learn how to complete that math problem, learn, not because you feel like you have to, but because you want to.
Never let school make you lose a love for learning.
I made a video game metaphor but, when I was finding the video that made me realize this I read another video game metaphor that explained it better, "So basically, as a gifted kid, I skipped the tutorial because it felt too easy. Then the actual game threw curveballs at me" (adorablehoe, 2nd top comment).

How the Geneva Drive (the mechanical step that makes the second hand on a clock work by turning constant rotation into intermittent motion) works.
If the oxygenator breaks down, I’ll suffocate. If the water reclaimer breaks down, I’ll die of thirst. If the hab breaches, I’ll just kind of implode. If none of those things happen, I’ll eventually run out of food and starve to death. So, yeah. I’m fucked. - The Martian, dir. Ridley Scott
