FIBONACCI SEQUENCE SCIENCE WHY ITS IN NATURE SKIN

In many cases this results in a Fibonacci spiral. These genetics get passed down and are refined until we obtain a very efficient way of packing seeds.

FIBONACCI SEQUENCE SCIENCE WHY ITS IN NATURE SKIN

Note that the seeds of a pineapple are underneath the skin of the fruit and are indicated by dark dots while pinecone seeds hide on the outside behind their scales. Thus, when it comes down to reproduction, a plant which is able to pack more seeds into its fruit is more likely to survive than a similar plant which which is able to pack less seeds into its fruit. In the process of natural selection, plants develop features which give them the best chance for survival. They even built some of their buildings based on this idea. The Ancient Greeks called this proportion golden because they saw it as the most beautiful and perfect ratio to ever exist. Many people are still debating over this, although it is said that the ratio between the proportions of your finger bones, the proportion of your hand to your forearm and even the distances between different parts of your face show the golden ratio, but this hasn’t been shown to be true overall. The shell of a Nautilus contains proportions which are golden and it is said that proportions within animals and humans are golden as well. Where else does the Fibonacci sequence appear?

The angle between one seed and another seed is the Golden ratio times 360 degrees in a sunflower. The golden ratio is the ratio between successive Fibonacci numbers. How does the golden ratio manifest in plants? But it gives an indication that the golden ratio is involved in the way the seeds are distributed. The spirals are just a phenomenon that we see with our pattern recognizing brains. Why is there a Fibonacci number of spirals in the pineapple/flower/pinecone? If the participants are curious, explain to them the Golden Ratio by obtaining two pairs of consecutive Fibonacci numbers, either from the sequence itself or from their recorded readings of the objects available, and divide the largest number by the smaller one to obtain the golden ratio.Įxplain the several other places the Golden Ratio and Fibonacci numbers crop up in nature and anatomy, as well as how it relates to the examples you’ve shown. Show that the number of spirals in the seedhead and the spirals in the stems of the plants consist of Fibonacci numbers. Now introduce and describe to the participants the Fibonacci sequence.Īllow the participants to realize the fact that all the spirals and petals they counted are in the Fibonacci sequence.Ĭonsolidate this concept by showing participants images of sunflower seeds. Take care not to destroy the delicate structure of the flowers. Participants should be aware of the collection of fruit and plant life available in the experiment.īegin by counting the number of spirals in each direction (clockwise and anticlockwise) on the pineapple (aided with the coloured tape), the number of petals on the flowers, the spirals on the pine cone etc.
