The Feynman Technique for learning

The Feynman Technique is perfect for learning a new idea, understanding an existing idea better, remembering an idea, or studying for a test.
The Feynman Technique is a mental model that was coined by Nobel-prize winning physicist Richard Feynman. Known as the “Great Explainer,” Feynman was revered for his ability to clearly illustrate dense topics like quantum physics for virtually anybody. It is said that Feynman prided himself on being able to explain the most complex ideas in the simplest terms. Feynman was once asked to explain why “spin one-half particles obey Fermi-Dirac.” Feynman replied that he’d prepare a freshman lecture on it, but then he came back a few days later empty handed. “I couldn’t reduce it to freshman level,” he admitted to Goodstein. “That means we don’t really understand it.” That is to say, if Feynman couldn’t explain something in simple terms, there was a problem with the information, not with Feynman’s teaching ability.
so here’s his technique
1. Pick a topic you want to understand and start studying it. Write down everything you know about the topic on a notebook page, and add to that page every time you learn something new about it.

2. Pretend to teach your topic to a classroom. Make sure you’re able to explain the topic in simple terms.

3. Go back to the books when you get stuck. The gaps in your knowledge should be obvious. Revisit problem areas until you can explain the topic fully.

4. Simplify and use analogies. Repeat the process while simplifying your language and connecting facts with analogies to help strengthen your understanding.
