Presentation Title: Mathematics in the Modern World
Slide 14: The Golden Ratio (( \phi ))
- Formula: ( \fraca+ba = \fracab = 1.618... )
- Visual: A golden rectangle with a spiral drawn inside.
- Pronunciation: “Phi” (like “fee”).
- Key fact: The ratio of consecutive Fibonacci numbers (e.g., 34/21) approaches 1.618.
Slide 4: What is Mathematics? (Definition)
Formal Definition:
- The study of quantity, structure, space, and change. Modern View:
- A language for describing the universe.
- A system of logical reasoning.
- An art of pattern recognition.
Slide 23: The Danger of Flawed Induction – The Black Swan Problem
- Visual: A black swan swimming.
- Story: For centuries, Europeans saw only white swans → Inductively concluded “All swans are white.” Then they explored Australia.
- Lesson: One counterexample breaks an inductive rule.
Slide 10: Symmetry – The Simplest Pattern
- Visual: A butterfly (bilateral symmetry) next to a starfish (radial symmetry).
- Text:
- Bilateral: Mirror image (left/right).
- Radial: Rotational symmetry (starfish, snowflakes).
