Feynman Technique
Introduction
The Feynman Technique is a powerful learning method named after the Nobel Prize-winning physicist Richard Feynman, who was known for his deep understanding of complex concepts and his ability to explain them simply.
The Feynman Technique is a 4-step process designed to help you understand any topic more deeply and quickly by teaching it to someone else in plain language.
The 4 Steps of the Feynman Technique
- Choose a Concept
Pick a topic or concept you want to learn or understand better.
Example: "Photosynthesis" or "Supply and Demand"
- Teach It to a Child (or in Simple Terms)
Write down everything you know about the concept as if you're teaching it to a 12-year-old; use simple language, analogies and avoid jargon.
This step forces you to clarify your thinking.
- Identify Gaps and Go Back to the Source
When you struggle to explain something, that highlights a gap in your understanding. Go back to your notes, textbooks, or trusted resources to fill in those gaps.
- Simplify and Use Analogies
Once you've filled the gaps, simplify your explanation even more. Use analogies and real-world examples to make the idea clear and relatable. Repeat the process until you can explain the concept smoothly and confidently.
Why the Feynman Technique Works
- Forces Active Recall (you have to retrieve knowledge without prompts.)
- Reveals Gaps (shows what you don’t fully understand.)
- Boosts Understanding (explaining teaches you.)
- Improves Memory (simplified, connected knowledge sticks longer.)
Summary
"…It's a way to learn by pretending you're the teacher. You pick something you want to understand, then explain it like you're teaching a kid. If you get stuck, it means you need to study more. Once you get it, you explain it again—more simply and clearly…"
