A 3-Minute Recap of the ‘Feynman Technique’ and How to Use It to Supercharge Your Learning

Summary

The Feynman Technique is a method for supercharging learning by writing explanations in simple language, identifying knowledge gaps, and iteratively refining understanding.

Abstract

The Feynman Technique, named after the Nobel Prize-winning physicist Richard Feynman, is a learning strategy that emphasizes deep understanding through explanation, review, and refinement. It involves writing down the topic, explaining it in simple terms as if teaching a beginner, identifying areas of difficulty, and revisiting source material to clarify misunderstandings. The process is repeated until the learner achieves a clear and comprehensive grasp of the subject. Feynman's approach to learning is celebrated for its ability to distill complex ideas into understandable concepts, and his teaching legacy is exemplified by his series of physics lectures, which remain a valuable resource for students and enthusiasts.

Opinions

Richard Feynman's ability to simplify complex subjects and his relentless curiosity are highlighted as key aspects of his learning method.
The technique suggests that true understanding comes from being able to explain a concept in basic terms, using analogies and visualizations.
Feynman's method encourages learners to be honest about their knowledge gaps and to actively seek out a deeper understanding.
The use of handwriting in the learning process is advocated, based on research showing it strengthens conceptual understanding compared to typing.
Feynman's pedagogical skills are evidenced by his series of physics lectures, which are praised for their clarity and accessibility.
The Feynman Technique is not just for academic success but also for personal growth, creativity, and the joy of learning.

After all, he was “The Great Explainer”!

Richard Feynman (1918–1988) was an eminent American Nobel Prize-winning physicist known just as much for his coruscating charisma and quirks as for his scientific genius. He possessed the seemingly mystical ability to take advanced subject matter, and distil it into beautifully lucid explanations from which even complete laypeople could glean understanding.

Feynman didn’t just know things. His rapacious curiosity ensured that he would question and question and question some more, until he had mastered everything down to the very bedrock of a subject. He revelled in understanding the most granular details of the natural world and seeking fascinating connections between disparate branches of physics.

“Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.” — Richard Feynman

What has today become known as ‘The Feynman Technique’ was a method frequently employed by Feynman in his technical notebooks to help him learn with both ample breadth and depth. Here’s how it works:

1) Write the topic or concept name at the top of a blank piece of paper. Of course you can also use a word processor, but for this exercise I’d advise using the former due to studies demonstrating that the learning process and your conceptual understanding is strengthened through handwriting.

2) Write an explanation underneath using simple everyday (i.e. with limited jargon) language. Imagine that you’re writing the material down in this way to teach an absolute beginner to the topic, or even a child. Use visualisations, analogies and metaphors if needed. Tell a compelling story. During this process, if you notice yourself faltering or you struggle to express an idea in the simplest possible terms, make a note of it. This is most likely a gap in your knowledge that you can now work to solidify.

3) Review and fill in the aforementioned weaker areas you pinpointed by firstly returning to the source material to see if anything ‘clicks’ this time around. If not, cast a wide net — scour the internet, look at any textbooks you have available or converse with someone who does get it. Once you believe you’ve grasped it, carefully re-run through the incremental steps in your understanding to make sure. Take the time you need to satisfy your mind through the logical harmony of a eureka moment, and remember:

“The first principle is that you must not fool yourself and you are the easiest person to fool.” — Richard Feynman

4) Iterate and refine. Time to try ‘teaching’ the topic again in light of the adjustments you made. Reframe things in your own words and avoid copying the source material verbatim, as this can beguile you into not properly processing and absorbing the information! Have you used any superfluous or confusing language? Have you made any unjustified or unexplained assumptions in your reasoning? Do you feel convinced upon reading your notes and listening to yourself speak aloud that you fully comprehend the topic?

Happy learning!

Make it to the other side of these four steps and you’ll pave the way for a far deeper and more profound understanding that you can use to ace tests, advance your career, be more creative, satiate your curiosity or even (if you’re so inclined) regale people at parties!

As an aside, for proof of Feynman’s exceptional gift for pedagogy, look no further than his acclaimed series of physics lectures which he delivered to undergraduate students at Caltech (1961–1963) — all of which are free to view and be enlightened by online.
