Most Math Lectures Make Me Want To Take A Nap. This One Made Me Rethink Most Of Earth's Problems.

Gabe Stein

I'll be honest: For the first 30 seconds, you're going to wonder why you're watching what appears to be a boring lecture about math. Hang in there. By the time you get to 6:30, you'll be super-excited by how quickly you learned this critical concept — and even more worried about what it means for our future. Hopefully, you'll want to make sure everyone else you know learns it too.
