Feynman Technique
The Feynman Technique is a learning strategy that tests understanding by explaining concepts in simple terms. Its core idea: if you can’t explain it simply, you don’t truly understand it.
📚 What is the Feynman Technique?
The Feynman Technique is a learning method proposed by Nobel Prize-winning physicist Richard Feynman.
Its core principle is: “If you can’t explain it simply, you don’t really understand it.”
In simple terms:
When you learn something new, pretend you’re teaching it to a child. If you can explain it clearly in plain language, you understand it. If not, you need to go back and learn again.
🧑🔬 Origin & Key Figures
- Creator: Richard Feynman, physicist and Nobel laureate
- Background: Famous for making complex physics understandable through vivid metaphors, Feynman summarized this as a learning method.
- Adopters: Widely used by educators, trainers, and self-learners.
- Classic Example: Feynman explained quantum mechanics with everyday examples like rubber bands and ping-pong balls, making science accessible.
🛠️ How to Apply the Technique
The method usually involves four steps:
- Choose a concept
- Pick a specific topic you want to learn.
- Explain it in your own words
- Pretend you’re teaching a child. Use simple, clear language.
- Identify gaps
- Notice where you struggle or can’t explain smoothly. Go back to study those areas.
- Simplify and use analogies
- Reorganize the knowledge with simple words and relatable examples.
📖 Case Studies
- Case 1 (Business)
A consultant explaining “blockchain” realizes clients don’t understand technical terms. He reframes it: “Blockchain is like a public ledger everyone can see, and once something is written, it can’t be changed.” The client immediately understands.
Lesson: Simplicity is power.
- Case 2 (Learning)
A student studying Newton’s First Law first memorizes: “An object in motion stays in motion unless acted upon by force.” But to teach a child, he says: “If a ball is on the table, it won’t move unless you push it. If it’s sliding on ice, it’ll keep sliding until something stops it.”
Lesson: Analogies make abstract concepts tangible.
✅ Strengths & Limitations
