Golden Ratio In Nature

Fibonacci Sequence AKA Golden Ratio: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89

Background Information

- Leonardo Fibonacci was the founder of the sequence, "The Golden Ratio." - He was working on an experiment, "the ideal expansion pairs of rabbits over one year," and found the sequence when calculating it.- The ratio is an irrational number and it has no pattern.

Example 1: Flowers

Example 2: Pineapple Arms

- The number of petals consistently follows the Golden Ratio. *Each petal is placed at 0.618034 degrees per turn (out of 360 degrees) which allows it for the best exposure to sunlight! *The daisy grows in 2 spirals extending out from the center. The 1st spiral has 21 petals. The 2nd spiral has 34 petals.

- The spirals of a pineapple follows the Golden Ratio also!* It's spirals consists of 5, 8, and 13. That goes with PINE CONES too!This is obviously not a coincidence to nature. There's more evidence to prove it, but these are two of the examples/evidence that interest and caught my attention.

Golden Ratio Value: 1.61803398874989......so on

Fun Facts: - The Golden Ratio appears a lot in geometry, art, and architecture. - It's also known as the Golden Section, Golden Mean, Golden Number and Divine proportion.
