    The Feynman Technique: Learn Anything by Teaching It

    Named after Nobel Prize-winning physicist Richard Feynman, this technique uses teaching as a tool for learning. If you can't explain something simply, you don't understand it well enough.

    The Core Principle

    Richard Feynman believed that the best way to learn is to teach. When you attempt to explain a concept in simple terms, you quickly discover gaps in your own understanding.

    "If you can't explain it to a six-year-old, you don't understand it yourself."
    Often attributed to Albert Einstein

    The Four Steps

    1

    Choose a concept

    Write the name of the concept at the top of a blank page.

    2

    Teach it to a child

    Write an explanation as if teaching a 12-year-old. Use simple language, avoid jargon.

    3

    Identify gaps and return to source

    When you get stuck, go back to your source material and study until you can explain it simply.

    4

    Simplify and use analogies

    Review your explanation and simplify further. Create analogies that connect to familiar ideas.

    Why This Works

    • Exposes illusions of competence: Reading about something feels like learning, but can you actually explain it?
    • Forces active processing: Teaching requires organizing information and making connections.
    • Builds transferable understanding: Simple explanations indicate deep comprehension.
    • Creates useful study materials: Your explanations become effective revision notes.

    Practical Example

    Topic: Photosynthesis

    Complex version: "Photosynthesis is a biochemical process wherein chloroplasts utilize light energy to synthesize glucose through the light-dependent and light-independent reactions."

    Feynman version: "Plants make their own food using sunlight. The green parts of plants catch light like tiny solar panels. They use this energy to turn water from the soil and carbon dioxide from the air into sugar."

    Prefer a guided version? The Feynman technique with AI uses an AI as your "student" – exposing weak spots faster than teaching a real person – and pairs well with a well-built revision sheet.

    Warning Signs You Don't Understand

    • • Relying on technical jargon
    • • Unable to give a concrete example
    • • Explanation sounds like the textbook
    • • Can't answer "why" questions
    • • Skipping parts of the explanation
    • • Feeling frustrated or stuck

    Key Takeaways

    • • Teaching is the most effective form of learning
    • • Simple explanations require deep understanding
    • • Jargon often masks incomplete knowledge
    • • Analogies help connect new concepts to existing knowledge
    • • The goal isn't simplicity for its own sake. it's clarity
    • • Return to source material whenever you get stuck
