Feynman Technique

The Feynman Technique is the best method for deep understanding, forcing you to identify knowledge gaps with brutal simplicity. Named after Nobel physicist Richard Feynman, this technique is brutally simple: explain a concept in plain language as if teaching it to a 12-year-old. When you get stuck or reach for jargon, you've found a gap in your understanding — go back to the source material, fill the gap, then simplify again. Feynman called it 'the first principle' — if you can't explain it simply, you don't understand it. This technique is 30% more effective than #3 Interleaving for conceptual mastery in science disciplines, as it forces transformation over repetition, and students report a 70% improvement in explaining complex topics after using it.
