The Feynman Technique: Master Any Subject by Teaching It Simply
Discover the powerful learning method used by Nobel Prize winner Richard Feynman to understand complex concepts and identify knowledge gaps through simple explanations.
"If you can't explain it simply, you don't understand it well enough."— Often attributed to Albert Einstein
What is the Feynman Technique?
The Feynman Technique is a learning method developed by Nobel Prize-winning physicist Richard Feynman, known for his ability to explain complex scientific concepts in simple, understandable terms. This technique is based on the principle that teaching is the ultimate test of understanding.
Named after the physicist who was famous for his clear explanations of quantum mechanics and other complex topics, this method helps you identify gaps in your knowledge and deepen your understanding of any subject through the act of explanation.
The Four Steps of the Feynman Technique
Choose a Concept
Select a topic or concept you want to learn or understand better. Write it at the top of a blank page. This could be anything from a scientific principle to a historical event, a business concept, or a mathematical formula.
Explain It Simply
Write out an explanation of the concept as if you were teaching it to someone else—ideally someone without expertise in the subject. Use simple language, avoid jargon, and focus on the core ideas. Pretend you're explaining it to a child or a friend who's completely new to the topic.
Identify Knowledge Gaps
Review your explanation and identify areas where you struggled, used complex terminology, or couldn't provide clear examples. These gaps reveal where your understanding is incomplete. Don't worry—this is the most valuable part of the process!
Review and Simplify
Go back to your source material and study the areas where you identified gaps. Then return to your explanation and revise it, making it even clearer and simpler. Repeat this process until you can explain the concept fluently without referring to complex terminology or source materials.
Why the Feynman Technique Works
Active Learning
Unlike passive reading or listening, explaining concepts forces your brain to actively process and organize information, leading to deeper understanding and better retention.
Gap Identification
The technique reveals exactly where your understanding breaks down, allowing you to focus your study efforts on the areas that need the most attention.
Mental Models
By breaking down complex ideas into simple explanations, you build stronger mental models that help you understand related concepts and solve problems more effectively.
Long-term Retention
The process of simplification and repetition strengthens neural pathways, making the information more likely to stick in your long-term memory.
Practical Examples
Physics: Explaining Gravity
"Gravity is like a invisible force that pulls things toward each other. The bigger something is, the stronger its pull. That's why we stick to Earth instead of floating away, and why the Moon orbits around us instead of flying off into space."
This simple explanation avoids complex terms like "gravitational field" or "mass-energy equivalence" while capturing the essential concept.
Economics: Supply and Demand
"Supply and demand is like a seesaw. When lots of people want something but there isn't much of it available, the price goes up. When there's plenty of something but not many people want it, the price goes down. It's how markets naturally balance themselves."
This explanation uses a familiar analogy (seesaw) to make an abstract economic concept concrete and understandable.
Tips for Mastering the Feynman Technique
Use Analogies and Examples
Connect new concepts to familiar experiences. Analogies make abstract ideas concrete and memorable.
Write It Down
The physical act of writing engages different parts of your brain and helps identify gaps in your thinking.
Practice with Others
Actually explain concepts to friends, family, or study partners. Their questions will reveal gaps you might miss on your own.
Embrace Iteration
Don't expect perfection on the first try. The technique works through repetition and refinement.
Think Like a Child
Children ask "why" constantly. Channel that curiosity to dig deeper into concepts and challenge your assumptions.
Be Patient
Deep understanding takes time. Don't rush the process—let your brain work through the complexity gradually.

The Feynman Technique is more than just a study method—it's a way of thinking that can transform how you approach learning and problem-solving. By forcing yourself to explain concepts simply, you'll develop a deeper, more intuitive understanding of any subject.
Remember, the goal isn't to sound smart or use impressive terminology. The goal is to understand so clearly that you can make complex ideas accessible to anyone. As Richard Feynman himself demonstrated throughout his career, true mastery comes from simplicity, not complexity.
