🧠 Master Anything with the Feynman Technique

“If you can’t explain it simply, you don’t understand it well enough.” – Richard Feynman.

Richard Feynman was a Nobel Prize-winning physicist—not just for his brilliance in science, but for his unmatched ability to explain complex ideas in simple language. That’s the core idea behind the Feynman Technique, a powerful learning method that helps you deeply understand any topic—whether it’s quantum mechanics or your monthly budget.

In this blog, we’ll walk you through:

• What the Feynman Technique is

• Why it works

• Step-by-step how to use it

• A real-world example: Learning Compound Interest

• Tips to get the most out of it

🎯 What Is the Feynman Technique?

The Feynman Technique is a 4-step learning framework that pushes you to teach what you’ve learned in the simplest way possible. The logic is simple: If you can teach it, you truly understand it.

🧩 Why It Works

• Forces you to simplify complex topics

• Reveals knowledge gaps quickly

• Reinforces long-term memory through explanation

• Helps you avoid passive learning (e.g., just reading or watching)

🪜 The 4 Steps of the Feynman Technique (with Example)

Let’s say you want to understand Compound Interest.

---

Step 1: Choose a Concept and Write It Down Simply

Pick the concept you want to master. Write the topic at the top of a blank page.

📝 Topic: Compound Interest

Write down what you understand as if explaining to a 12-year-old.

“Compound interest is money you earn on both your original money and the money that money makes over time.”

Include examples:

“If you put $100 in a savings account and it earns 10% interest per year, you get $10 after the first year. But in the second year, you get 10% of $110—not just $100—so you earn $11. And it keeps growing like that!”

---

Step 2: Teach It (Out Loud or on Paper)

Now explain it out loud like you’re teaching someone who has no idea what compound interest is. Use simple analogies.

“It’s like planting a tree that grows fruit. Then those fruits grow into new trees that also grow fruit. After a few years, you have an entire forest making fruit.”

The goal: Make it easy, not fancy.

---

Step 3: Identify Gaps and Go Back to the Source

Stuck? Can’t explain something clearly? Great! That’s a knowledge gap. Go back to your notes, books, or videos to fill in the blanks.

Example:

❓ “Wait—why does the growth get faster over time? Is there a formula for that?”

Look it up and add it:

“Yes! The formula is A = P(1 + r)^n. That’s because interest is calculated on the new total each time.”

Now you’ve leveled up.

---

Step 4: Simplify and Use Analogies

Now go back to your explanation and make it even simpler. Remove jargon. Use metaphors or visuals if needed.

🔄 Refined Explanation:

“Compound interest is like a snowball rolling downhill. It starts small, but as it rolls, it gathers more snow. The more snow it gets, the bigger it becomes, and the faster it grows.”

🚀 Real-Life Application Ideas

You can use the Feynman Technique to master:

• 📚 School subjects (Math, Science, History)

• 💼 Work topics (Cloud Computing, Blockchain, Finance)

• 🧘‍♀️ Personal learning (Nutrition, Investing, Habits)

• 🧪 Technical skills (React.js, Machine Learning, Kubernetes)

---

💡 Pro Tips for Success

• Use a journal: Create a “Feynman Notebook” for each topic

• Teach others: Even better than writing—explain to a friend or family member

• Use plain language: Avoid hiding behind technical terms

• Repeat the cycle: Keep refining your explanation each time you revisit

📈 How It Changed My Learning

I used this technique to prepare for a presentation on blockchain, a topic I found confusing at first. By the end of the process, I could explain it to my 9-year-old niece—and she got it!

That’s the power of the Feynman Technique.

When you teach to understand, you learn to remember.
