Need Some Brain Power? Use The Feynman Technique to Learn (Almost) Anything and Build a Second Brain!

The Feynman Technique is one of the simplest yet effective ways to learn new things. Whether you’re into productivity, marketing, or quantum physics, this four-step framework will help you acquire knowledge in a refreshing and surprisingly humbling way.

Learning things by heart sucks. It’s monotonous, uninspiring, and you’re likely to start bleeding key facts as soon as you don’t need them. And this is where the Feynman Technique, named after a famous physicist and science educator, comes into play.

In today’s article, you’ll rediscover the child-like curiosity of learning. You’ll also learn (no pun intended) how to use outlining and mind mapping to make that knowledge stick.

Here’s an overview of the article. 👇

What Is the Feynman Technique? 🤔

Who Was Richard Feynman? ⚛️

Regarded as one of the greatest physicists of all time(1), Richard Feynman was an avid science educator and a vibrant figure in the scientific world. His work earned him multiple awards, including the Albert Einstein Award (1954) and the Nobel Prize (1965) for his contribution in the field of quantum electrodynamics.(2)

On top of being an accomplished scientist, Feynman reveled in teaching others. His unorthodox academic style, a peculiar sense of humor, and an exceptional ability to elucidate complex topics earned him a nickname the “Great Explainer.”

“Incidentally, Feynman wasn’t famous just for being a great teacher and a world-class scientist; he was also quite a character. He translated Mayan hieroglyphics. He loved to play the bongos. While helping develop the atomic bomb at Los Alamos, he entertained himself by figuring out how to break into the safes that contained top-secret research.”

Bill Gates, “The Best Teacher I Never Had”(4)

As it is the case with history’s most successful figures, it’s natural to think of Feynman as an outlier who was simply “gifted” in what he did. While he was considered a genius, Feynman attributed his track record to an iterative learning process.

Feynman didn’t put much faith in innate abilities. Instead, he focused on getting under the surface of everything he wanted to learn. As he points out in his memoir Surely You’re Joking, Mr. Feynman!, the point of learning is not to memorize but to understand.

“I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way — by rote, or something. Their knowledge is so fragile!”

Richard P. Feynman, Surely You’re Joking, Mr. Feynman!

Feynman’s common-sense approach to acquiring knowledge crystallized in what’s known as the Feynman Technique. The technique breaks down into four key steps. 👇

  • 🌟 Step 1: Pick a topic and start learning about it.
  • 🌟 Step 2: Imagine you’re explaining the topic to a child.
  • 🌟 Step 3: Identify what you still don’t know and dig deeper.
  • 🌟 Step 4: Simplify and turn knowledge into a gripping narrative.

This simple four-step framework strips the learning process of jargon, ambiguity, and complexity and improves comprehension. But before we explain it in detail, let’s take a look at some of the cool benefits of the Feynman Technique.

What Are the Benefits of the Feynman Technique? ⚡️

You Approach Things With an Open Mind 🌱

Children and adults see the world in completely different ways. Whenever you approach a new subject, you do so burdened by prejudice and bias. A child’s mind, on the other hand, soaks everything up indiscriminately and with genuine excitement.

“Asking questions is what brains were born to do, at least when we were young children. For young children, quite literally, seeking explanations is as deeply rooted a drive as seeking food or water.”

Alison Gopnik, professor of philosophy at UC Berkeley

The Feynman Technique helps you awaken that child-like mind. By shedding preconceived notions, you rediscover the joy of learning. This is incredibly humbling and refreshing and helps you understand how much you don’t know.

You Learn How to Ask Better Questions 💭

You start life with no answers and only advance by asking the right questions, and we mean a lot of those. Children do that all the time. They probe the most mundane aspects of everyday life to the point where there’s nothing else left to uncover.

By improving your questioning capacity, you become more effective at poking and probing your own knowledge. This, in turn, can help you identify gaps and inconsistencies, and what’s really fun, extract knowledge from experts around you.

You Reduce Friction in Communication 📣

We live in a noisy world. You probably send and receive dozens of emails and texts each day. That’s on top of the hours spent on calls and video conferences. But what part of that communication smorgasbord do you consider essential and effective?

“These, then, are the ten rules of effective communication, all summarized in single words: simplicity, brevity, credibility, consistency, novelty, sound, aspiration, visualization, questing, and context.”

Frank Luntz, Words That Work

The Feynman Technique celebrates the art of meaningful communication. It allows you to remove unnecessary complexity and explain intricate topics in a frugal and accessible way. After all, why use three words when one would do?

How Do You Use the Feynman Technique? 👉

Step #1: Pick a Subject and Start Learning 🎯

This part isn’t much different from what you’d normally do to learn something new. Pick a topic you’re interested in, make a comprehensive list of resources, and dig in. The only rule is that you should learn to comprehend rather than just to remember.

If you’re dealing with a new topic, read broadly and focus on getting a holistic view of the subject. Don’t worry if you don’t soak up all the details at this stage. Keep your primary sources at hand as you’ll likely come back to them in the next step.

👁 Pro Tip: Use Mind Mapping for a Bird’s Eye View

You can use Taskade’s Mindmap view to see all the moving parts of a topic, thought, or idea. Start by putting a core theme in the center and add new branches as you go. You can even upload images, videos, and other materials to improve retention.

Here’s a simple #healthy_living mind map created in Taskade. 👇

Step #2: Teach Yourself as You Would a Child 🍼

Now comes the fun part. Pretend you’re about to explain what you’ve just learned to a child — or actually do that if you’re a parent! — in the simplest way possible. Use plain language, avoid jargon, rely on analogies, and do that as quickly as possible.

Here’s an excellent example from Wired’s “5 Levels” series. 👇

This step will put your knowledge to the test and help identify potential potholes. Even if you think you’ve mastered a subject, chances are there’s still much you don’t know. And a battery of deceptively simple wh-questions is the best way to expose that.

💬 Pro Tip: Keep Track of the Questions You Can’t Answer

You can pretend you’re giving a lecture to an imaginary audience with no prior knowledge of the subject. You can even talk to a mirror or record yourself for better effect. Come up with thought probing questions and add them to your mind map.

Step #3: Fill In the Gaps in Your Knowledge 🩹

Chances are the previous step exposed gaps in your knowledge of the subject. You may lack names, dates, or other key facts and details. Whatever it is, go back to the source and fill in the blanks so you can make a better job of teaching others.

“One of the best habits a learner can instill in herself is regular self-quizzing to recalibrate her understanding of what she does and does not know.”

Peter C. Brown, Make It Stick: The Science of Successful Learning

It may happen that the source material is lacking in some way. If that’s the case, cast a wider net and dig into more in-depth resources. Better still, seek out subject-matter experts and pester them with questions you prepared in the previous step.

Step #4: Simplify and Tell a Grand Story 🌟

Children love stories. Heck, even grown-ups fall for captivating yarns told by the fireside. Use the power of storytelling to fit what you’ve learned into a context, solidify the knowledge, and make the process even more exciting by retelling it yourself.

Combine the notes and questions from the previous steps, summarize what you know about the subject, and create a story to revisit every time you feel you need a refresher. Be sure to check Tiago Forte’s progressive summarization method for guidance.

🧙‍♂️ Pro Tip: Turn Your Mind Map into an Outline

Outlining is a great way to organize all kinds of information. Assembling facts, dates, and events in a hierarchical order will help you see how each element fits the bigger picture. Taskade allows you to transform your mind map into an outline in a blink.

And that’s it!

Parting Words 🐑

Let’s face it. For many of us, the excitement of learning new things⁠ — and often even the inclination to do so⁠ — fades once we transition into adulthood. The mundane of everyday life takes over and it becomes increasingly difficult to feel the “magic.”

The Feynman Technique puts curiosity back on the menu. It helps open the mind and rediscover the pure joy of exploring the unknown with a child-like mind.

So, what are you waiting for?

  1. 🎯 Pick a subject and start learning.
  2. 🍼 Teach yourself as you would a child.
  3. 🩹 Fill in the gaps in your knowledge.
  4. 🌟 Simplify and tell a grand story.
