Summary

This walks you through the classic Feynman learning technique: explain a concept in plain language, spot where you're hand-waving or using jargon you can't define, research those gaps, then rewrite it better. It's structured as a four-step template with tables for tracking vague spots and undefined terms. Good for when you're learning something technical and want to actually understand it rather than just memorize definitions, or when you're preparing to teach and need to find the holes in your mental model. The "explain to a 12-year-old" bar forces you to confront what you don't really get yet, which is the whole point.

Feynman Technique

Apply the full Feynman learning technique to deeply understand a concept.

Instructions

Work through all four steps of the Feynman technique. Be honest about gaps—they're the point.

Output Format

Concept: [What are we trying to understand?]


Step 1: Explain It Simply

Explain as if teaching someone with no background in this field

Simple Explanation

[Write a plain-language explanation. Use everyday words. Avoid jargon. Aim for a bright 12-year-old to understand.]

Analogy

[Create an analogy using something familiar to illustrate the concept]


Step 2: Identify Gaps

Where did the explanation get fuzzy, hand-wavy, or require jargon?

Gaps Found

GapWhat I SaidWhat I'm Not Sure About
1[vague part][the underlying question]
2[vague part][the underlying question]
3[vague part][the underlying question]

Jargon Used

TermCan I Explain It Simply?
[term]Yes / No / Partially

Step 3: Fill the Gaps

Research or think through each gap

Gap 1: [Topic]

  • The question: [What wasn't clear?]
  • The answer: [What I learned]
  • Now I can explain it as: [Simple version]

Step 4: Refined Explanation

Rewrite the complete explanation with gaps filled and simpler language

Final Simple Explanation

[The improved, complete explanation in plain language]

Improved Analogy

[A refined or new analogy that better captures the concept]

Key Takeaways

  1. [Core insight 1]
  2. [Core insight 2]
  3. [Core insight 3]

Test Question If someone asked me to explain this in 30 seconds, I'd say:

[Elevator pitch version]

Guidelines

  • Don't pretend to understand—gaps are valuable
  • Use analogies from everyday life
  • If you need jargon, define it simply
  • Shorter is usually better
  • The "explain to a child" bar is high—take it seriously
