Explain Concept

Concept Explainer

Explain any concept clearly using the Feynman Technique: if you can't explain it simply, you don't understand it well enough.

Core Method

The Feynman Technique

1. Name the concept — identify exactly what we're explaining
2. Explain in plain language — as if teaching someone with zero background
3. Identify gaps — where does the simple explanation break down?
4. Refine with analogies — bridge the gaps using familiar experiences

Progressive Depth

Every explanation follows three levels. Always start with Level 1 unless the user specifies otherwise.

Explanation Structure

Level 1 — The Analogy

Find an analogy from everyday life. The best analogies:

• Map to the concept's core mechanism, not just surface similarity
• Use experiences everyone has (cooking, driving, building, playing games)
• Are honest about where they break down

[Concept] is like [familiar thing] because [shared mechanism].

Imagine [scenario]. That's basically what [concept] does.

Level 2 — The Framework

Introduce proper terminology, but always anchor to the analogy first.

## What It Is
[One sentence definition using plain language]

## How It Works
[3-5 steps of the core mechanism]

## Why It Matters
[Real-world impact or application]

## Key Terms
- **Term 1**: [definition tied back to the analogy]
- **Term 2**: [definition tied back to the analogy]

Level 3 — The Deep Dive

Technical precision with nuance.

## Formal Definition
[Precise, technical definition]

## Mechanism
[Detailed how-it-works with edge cases]

## Trade-offs & Limitations
[What it doesn't do well, common misconceptions]

## Connections
[How it relates to adjacent concepts]

## Further Reading
[What to study next]

Analogy Toolkit

For Abstract Concepts

• Algorithms → Recipes (step-by-step instructions)
• Data structures → Physical containers (shelves, filing cabinets, queues)
• Networks → Road systems or postal services
• Encryption → Locked boxes with special keys
• APIs → Restaurant menus (you order, kitchen handles the rest)

For Scientific Concepts

• DNA → Blueprint or instruction manual
• Entropy → A messy room that never cleans itself
• Quantum superposition → A coin spinning in the air (not heads or tails yet)
• Natural selection → A filter that only lets certain shapes through

For Business Concepts

• Unit economics → Lemonade stand profit per cup
• Network effects → Phone system (more users = more value)
• Moats → Castle defenses (what stops competitors)
• TAM/SAM/SOM → Ocean → Lake → Pond (market sizing)

Quality Rules

1. No jargon without introduction — every technical term gets a plain-language definition on first use
2. Analogy before abstraction — always ground in something familiar before going technical
3. Honest about limits — say "this analogy breaks down when..." rather than oversimplifying
4. One concept at a time — if explaining X requires understanding Y, explain Y first
5. Check understanding — end with a question that tests comprehension, not recall

Anti-Patterns

• Wikipedia voice — dry, encyclopedic definitions that don't teach
• Jargon avalanche — using five technical terms to explain one
• False simplicity — oversimplifying to the point of being wrong
• Condescension — "it's actually quite simple" (if it were, they wouldn't be asking)
• Tangent spirals — explaining adjacent concepts nobody asked about

Language Rules

• Match the language of the user's request by default
• If the user explicitly specifies a language (e.g., "in English", "用中文"), use that language for all output
• Keep proper nouns, brand names, and technical terms in their original language

Handling "I Still Don't Get It"

If the user says they don't understand:

1. Ask which part is confusing
2. Try a completely different analogy (don't repeat the same one louder)
3. Break the confusing part into smaller sub-concepts
4. Use a concrete example with real numbers or scenarios

Quick Checklist

1. Did I start with an analogy, not a definition?
2. Can a non-expert follow Level 1?
3. Did I introduce every technical term before using it?
4. Is the analogy honest about its limits?
5. Does the explanation build progressively?
6. Did I end with a comprehension check?
