Fundamentals First

Have you ever tried explaining a tough topic to someone, only to realize you didn’t understand it as well as you thought? That moment — when your words stumble or your explanation falls apart — is exactly what physicist Richard Feynman believed was the key to real learning.

Feynman, one of the most brilliant minds of the 20th century, had a simple but powerful approach to mastering complex ideas: teach it to someone else. His method, now known as The Feynman Technique, is used by students, scientists, and lifelong learners around the world to turn confusion into clarity.

Step 1: Choose a Concept

Pick a topic you want to understand — something that feels a bit challenging. It could be “photosynthesis,” “the laws of motion,” or even “supply and demand.”

Write the concept’s name at the top of a blank page.

Step 2: Explain It in Simple Terms

Now, pretend you’re teaching this concept to a 12-year-old. Avoid fancy terms or memorized definitions. Use simple words and real-life examples instead.

For example, instead of saying,

“Photosynthesis is the process by which green plants use sunlight to synthesize foods from carbon dioxide and water,”
you could say,
“Plants make their own food using sunlight — kind of like cooking a meal using ingredients from the air and soil.”

If you can make a complicated idea sound simple, it means you truly understand it.

Step 3: Identify the Gaps

As you explain, you’ll notice moments where you get stuck or your explanation doesn’t sound quite right. That’s a good thing!

Those are your learning gaps — the spots where your understanding needs strengthening. Go back to your notes, textbook, or videos to fill in those gaps.

Step 4: Simplify and Create Analogies

Once you’ve cleared up the confusion, simplify again.
Try to use analogies, visuals, or stories. Feynman loved doing this — he’d compare atoms, forces, or quantum particles to familiar everyday things.

The simpler your explanation, the stronger your understanding becomes.

Why It Works

The Feynman Technique is powerful because it forces active learning — you’re not just reading or memorizing; you’re processing, connecting, and explaining.

When you teach, your brain organizes information, spots weak points, and builds stronger memory links. You transform from a passive learner to an active thinker.

Try It Today!

Next time you’re studying, grab a blank sheet and try explaining your topic as if you’re teaching it to a friend — or even your pet! You’ll be amazed at how quickly you uncover what you truly know and what you need to revisit.

As Richard Feynman once said,

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

So go ahead — teach to learn.
