Episode notes
Fibonacci Leads To Phi
- Fibonacci ratios converge to the golden ratio phi ≈ 1.618 as n increases.
- The limit solves r = 1 + 1/r, linking sequence growth to a simple quadratic.
Self-Similar Rectangle Equals Phi
- A rectangle that recreates itself after cutting a square has aspect ratio phi.
- This geometric property links the golden ratio to recursive similarity.
Continued Fraction Ties Phi To Fibonacci
- Phi has an infinite continued-fraction of all ones, giving excellent rational approximations.
- Truncations produce Fibonacci ratios, explaining their frequent appearance in nature.
