Learn Like a Nobel Laureate
Richard Feynman believed that if you can't explain something simply, you don't truly understand it. Our lessons follow his four-step approach.
Wonder
Start with a question that sparks curiosity. Why does the sky look blue? Why do things fall down?
Explore
Dive into the concept with simple explanations, real-world examples, and interactive simulations.
Explain
Can you explain it to a friend in simple words? If not, go back and fill the gaps in your understanding.
Master
Test your knowledge with checkpoint quizzes. True understanding means you can teach it to anyone.
