A learning method developed by physicist Richard Feynman. The core idea: if you can't explain something in simple terms, you don't understand it well enough.

Steps

1. **Choose a topic** — pick the concept you want to understand.

2. **Teach it** — write an explanation as if teaching a child.

3. **Identify gaps** — when you get stuck, go back to the source material.

4. **Simplify** — refine your explanation until it's crisp.

Why it works

Explaining forces you to confront the limits of your understanding. You can't hide vague knowledge behind jargon when explaining to a novice.

[[Active Recall]] is a closely related idea — retrieval from memory strengthens the connection more than re-reading.
