Feynman Technique

The Feynman Technique is a study method named after Nobel Prize-winning physicist Richard Feynman.

It's a simple but effective way to improve your understanding of a topic by breaking it down into its simplest parts.

The technique involves explaining a concept in your own words as if you were teaching it to someone else, using analogies, drawings, or any other means that help you understand and retain the information.

Here's how to use the Feynman Technique

A[Choose a Concept] --> B(Write it down)
B --> C{Explain it as if teaching someone else}
C -->|Identify Gaps| D[Go back to the source material]
D --> E{Review and Simplify}
E --> F(Re-explain)
F --> G{Eliminate Jargon and Technical Terms}
G --> H(Repeat until you can explain it simply)
H --> I[Master the Concept]
  • Choose a topic you want to study.
  • Write down everything you already know about the topic.
  • Pretend to teach the topic to someone else. Write down the explanation as if you were teaching it to a student.
  • Identify any gaps in your understanding, where you struggle to explain the concept in your own words.
  • Go back and research those areas to fill in the gaps in your understanding.
  • Repeat the process until you can explain the concept easily and clearly, without referring to any outside resources.

The Feynman Technique is useful because it forces you to actively engage with the material, instead of passively reading or listening to someone else's explanation.

By teaching the concept to someone else, you are forced to think deeply about the topic and understand it at a deeper level.
