Ever feel like you’ve “learned” a complex pathway or drug mechanism, only to forget it two days later? Rote memorization has a ceiling, but true understanding is limitless.
Named after Nobel Prize-winning physicist Richard Feynman, this technique is a four-step process to ensure you actually know what you think you know.
1. Choose a Concept and Study It
Pick a topic you’re struggling with, perhaps the Coagulation Cascade or the Mechanism of CRISPR-Cas9. Write the name of the concept at the top of a blank sheet of paper.
2. Teach it to a Child (or a Non-Expert)
This is the “secret sauce.” Write out an explanation of the concept as if you were teaching it to someone without a science background.
Avoid Jargon: If you have to use a complex term, you must explain it.
Use Analogies: For example, describe Antibodies as “custom-made puzzle pieces” that lock onto “invaders” (Antigens) to signal the “cleanup crew” (Macrophages).
3. Identify the Gaps
When you struggle to explain a step simply, you’ve found a “knowledge gap.” Go back to your textbooks or resources and re-learn that specific part until you can explain it in plain English.
4. Review and Simplify
Organize your notes into a brief, clear narrative. Read it out loud. If the explanation sounds confusing or overly wordy, simplify it further.
This explains why understanding matters more than memorization. Teaching a concept in simple words really shows whether we’ve truly learned it or just remembered it temporarily.
A powerful reminder that true learning means understanding deeply enough to explain simply, especially invaluable for mastering complex medical and scientific concepts.
The Feynman technique is a time tested way of retaining complex topics in our memories. BY breaking the topic down and making it simple enough to explain to a six year old it ensures that there are no knowledge gaps in our thought process, everything flows seamlessly.
