Narrative Patterns for Math Explainers
Common structures used in effective 3Blue1Brown-style videos.
Pattern 1: Mystery → Investigation → Resolution
Structure:
- Present a puzzling result or paradox
- Investigate why it's true through visual exploration
- Reveal the underlying principle
- Show how the principle generalizes
Example topics: Euler's identity, Bayes theorem, infinite series paradoxes
Opening hooks:
- "What does it even mean to raise a number to an imaginary power?"
- "This equation looks wrong, but it's actually true..."
- "Most people get this probability question wrong..."
Pattern 2: Build Up → Payoff
Structure:
- Introduce simple building blocks
- Combine them to create something complex
- Show the beautiful/surprising result
- Reflect on why it works
Example topics: Fourier series, neural networks, linear algebra
Opening hooks:
- "Let's start with something simple..."
- "Each piece here is easy, but together they do something remarkable..."
Pattern 3: Two Perspectives → Unity
Structure:
- Show concept from perspective A (e.g., algebraic)
- Show same concept from perspective B (e.g., geometric)
- Reveal they're the same thing
- Explore implications of this connection
Example topics: Dot product, determinants, complex multiplication
Opening hooks:
- "There are two ways to think about this..."
- "These seem like completely different ideas, but..."
Pattern 4: Wrong → Less Wrong → Right
Structure:
- Present common misconception or naive approach
- Show why it fails
- Refine the approach
- Arrive at correct understanding
Example topics: Limits, probability distributions, definitions
Opening hooks:
- "Your first instinct here is probably wrong..."
- "The obvious approach doesn't quite work..."
Pattern 5: Specific → General
Structure:
- Solve a specific concrete example
- Notice patterns in the solution
- Abstract to general principle
- Apply to new situations
Example topics: Derivatives, group theory, algorithm analysis
Opening hooks:
- "Let's work through a specific example..."
- "Once you see the pattern here, it shows up everywhere..."
Pattern 6: History as Narrative
Structure:
- Present the problem as historically encountered
- Follow the journey of discovery
- Show key insights that led to breakthroughs
- Connect to modern understanding
Example topics: Calculus, cryptography, quantum mechanics
Opening hooks:
- "Imagine you're a mathematician in the 1600s..."
- "This problem stumped the greatest minds for centuries..."
Combining Patterns
Most effective videos combine multiple patterns:
- Mystery hook + Build Up explanation
- Two Perspectives + Specific → General examples
- Wrong → Right + History narrative
Pacing Guidelines
| Video Length | Intro Hook | Main Content | Recap/Implications |
|---|---|---|---|
| 5-10 min | 30-60s | 4-8 min | 30-60s |
| 15-20 min | 1-2 min | 12-16 min | 1-2 min |
| 30+ min | 2-3 min | 24-26 min | 2-4 min |
Emotional Arc
Every video should have emotional beats:
- Curiosity (opening) - Why should I care?
- Confusion (early) - This is harder than it looks
- Partial clarity (middle) - I'm starting to see...
- Aha moment (climax) - Oh! That's beautiful!
- Satisfaction (end) - Now I truly understand
