Richard Feynman was a Nobel Prize-winning physicist known for his incredible ability to understand and explain complex topics in a simple way. His method for learning is a brilliant tactical framework for anyone who wants to learn faster and more effectively.
The core idea is simple: you don’t truly understand something until you can explain it to a child. This forces you to get to the heart of the matter and expose where your knowledge is weak.
Step 1: Learn the Concept
Start by picking a topic or concept you want to learn. This could be anything—from the basics of coding to the rules of a new sport. Study it using your normal methods: read a book, watch a video, or listen to a podcast.
Step 2: Teach It to a Child
This is the tactical core of the method. Grab a notebook or a whiteboard and write down the concept at the top. Now, try to explain it in your own words, as if you were teaching it to someone who has no knowledge of the subject. Use simple language and analogies.
- Tactic: By using simple language, you immediately expose the gaps in your own understanding. You might think you know something, but when you can’t explain it in simple terms, you realize you’re just using jargon without true comprehension.
Step 3: Go Back and Fill the Gaps
When you get stuck—and you will—it means you’ve found a gap in your knowledge. Stop and go back to your source material. Re-read, re-watch, and study that specific area until you can explain it.
- Tactic: This is a crucial feedback loop. Instead of just pushing forward and hoping you’ll remember it later, you’re forced to correct your understanding in real-time.
Step 4: Simplify and Review
Once you can explain the entire concept simply, review your notes and your explanation. Make sure it’s as simple and elegant as possible. Now, you have a deep understanding of the topic and a clear, concise explanation you can always go back to.

Your Tactical Mission
The Feynman Technique isn’t just about learning—it’s about thinking. It trains you to move from surface-level knowledge to deep, applicable understanding. By using this simple method, you can turn any learning task from a passive activity into an active, tactical process, and achieve mastery much faster.
