Fibonacci Numbers - Myths and Facts

1999:  Discovery of Viswanath’s Constant – The growth rate of every random Fibonacci sequence is equal to 1.1319882….

2000: The mechanism controlling the radial positioning of leaves was found. Auxin, a plant hormone, regulates the maximal distance between blooming buds, and as a result the divergence angle between successive leaves approaches 137.508^o – “the golden angle”.

Early 21^st century: Debunking myths regarding the golden ratio in human anatomy, architecture, art, etc.

*    The ratio between successive terms in the Fibonacci sequence tends to a constant number:

*     1843: Jacques Binet published a direct formula for the terms of Fibonacci sequence:

* 1999: The random Fibonacci sequence: t₁=t₂=1, and each subsequent term is determined by a coin toss:

Ø  Heads – add the previous two terms,

Ø  Tails – subtract the previous term from its predecessor.
