How to Truly Understand Like Feynman#
We sometimes think "I get it," but when we actually try to explain it to someone, we find ourselves at a loss for words.
Nobel Prize-winning physicist Richard Feynman saw through this phenomenon and emphasized that true understanding means being able to explain something simply to others.
I believe the Feynman Learning Technique isn't about rote memorization -- it's a powerful method for making a concept truly your own.
In this post, I'll talk about how to apply the Feynman Learning Technique to your life and the changes that come with it.
TL;DL#
- Choose your concept
- Pretend you're teaching the idea to a new student
- If you get stuck, go back to the book
- Simplify and create analogies
1. Choose a Concept You Want to Understand#
First, you need to pick one concept you want to truly understand.
For example, "blockchain," "time management," "how savings interest is calculated" -- anything works.
What matters is that it's a topic you're curious about or want to understand more deeply.
If you choose a field that sparks your curiosity, you'll naturally focus and stay interested, making it an even better choice.
Examples:
- "What is an AI recommendation algorithm?"
- "How do you manage a schedule effectively?"
2. Explain It as If Teaching a New Student#
Now imagine explaining the concept you chose to a friend who knows nothing or to an elementary school kid.
Avoid jargon as much as possible and use simple words and examples.
Choosing difficult words can offload part of the understanding.
Through the process of explaining, you can check for yourself how well you actually understand it.
Example:
- "An AI recommendation algorithm is like when Netflix picks movies you might like -- it analyzes your taste and recommends things that fit. It's like a smart helper."
3. When You Get Stuck, Go Back to the Source Material#
If you get stuck while explaining, or if something feels vague or uncertain, that's a part you haven't fully understood yet.
Don't be embarrassed -- go back and look at books, the internet, or expert articles.
Then clarify that part and try explaining again. These days, we have AI, so it's even more reassuring.
4. Simplify and Create Analogies#
Now make your explanation even simpler and add everyday analogies and examples.
Even complex concepts become easier to understand -- for both you and others -- when broken down into familiar stories.
Example:
- "Blockchain is like a shared notebook that multiple people write in at the same time. If one person tries to change something, everyone can see it, so it's hard to cheat or tamper with."
5. Find the Gaps in Your Understanding and Make It Truly Yours#
Going through this process, it becomes clear which parts you're confused about and which parts you can explain well.
By filling in the gaps where your understanding is lacking, you'll be able to explain things more and more easily.
Ultimately, a concept you've fully understood can be conveyed clearly and simply to anyone.
Why I Apply the Feynman Learning Technique to My Life#
- It becomes truly mine: Not just rote memorization, but piercing through to the essence of a concept.
- Problem-solving skills grow: The deeper your understanding, the greater your ability to apply and create.
- Confidence builds: When you can explain something to others, you gain conviction in your knowledge.
In Closing#
The Feynman Learning Technique goes beyond being just a study method -- it's an attitude toward understanding the world and growing.
Starting today, pick a topic you're curious about and try explaining it as if to a young child.
If you get stuck, go back to the source material, and make it simpler with analogies and examples.
Knowledge understood this way has the power to change your life.
Failure will never overtake me if my determination to succeed is strong enough.
