Learn anything. See how everything connects.

Free from the textbook. Free to explore the whole universe.

Your teachers weren't wrong to teach you math in math class and history in history class.

They just had paper.

The derivative you're learning in calculus is the same idea economists use to find the exact moment a business should stop hiring, the same tool biologists use to model how fast a virus spreads, the same mathematics that made Newton understand why planets orbit the sun. Your math teacher knew this. They just had 45 minutes and 30 students and a textbook that ended at Chapter 12.

Feynman followed ideas wherever they led. That's the education we're giving you — not math class, not history class. The whole universe.
