Can't explain it
simply? You don't know it.
The Feynman Technique is a method for deeply understanding any concept by forcing yourself to explain it in plain, simple language — as if teaching a child. Named after Richard Feynman, the physicist famous for explaining complex ideas simply.
/What it is
Teaching activates generative processing — your brain has to organise and structure knowledge to explain it. Attempting to simplify forces you to confront exactly what you don't know. Fluency of explanation is a direct measure of genuine understanding.
/How to do it
- Pick a concept — one specific idea, not a whole subject
- Write the concept name at the top of a blank page
- Explain it in plain English — like teaching a 12-year-old. No jargon.
- Identify where you got stuck — vague language, skipped concepts, dead ends
- Go back to the source — but study only where you got stuck
- Simplify again — re-explain, this time filling the gaps
- Use analogies — connecting to something familiar proves you've got it
/Best for
- Concepts you keep reading but still don't fully understand
- Complex or interconnected ideas — not just facts to memorise
- Understanding why something works, not just what it is
- Debugging your own understanding — finding hidden gaps
/Common mistakes
- Using technical jargon and convincing yourself that counts as understanding
- Trying to apply it to an entire course at once instead of single concepts
- Skipping the "go back and fix the gap" step — the loop must close
- Doing it in your head only — writing or speaking externalises gaps
- Applying it to pure memorisation tasks where it's overkill

/Stack it with
- Active Recall — Use Feynman to go deeper on concepts that keep failing
- Pretesting — Identify which concepts need Feynman treatment
- Spaced Repetition — After cracking a concept, schedule it for review
Explain it like you're teaching a kid. Where you stumble is where you don't actually know it. Go fix that gap. Repeat until you can explain the whole thing cleanly. That's mastery.
