Where is the golden ratio hidden in nature?

Do you know where to find the golden ratio around you? And where does its name, Phi, come from? 

It is the Greek Phidias who materialized it for the first time in the Parthenon and it is in his honor that this number is called Phi. 

This harmony has always been present in nature and vacation time is the ideal time to go in search of it you can observe it in the flora especially in the heart of the daisy and the sunflower.
The seeds form two groups of spirals facing opposite directions. By adding the spirals in each direction, we observe that the ratio of the two sums is equal to 1.618.

But also in the fauna, in particular through the shellfish: the number of gold is arranged in the shells of the ammonite and the nautilus, under the form of a logarithmic spiral.

Phi 1.618 was inspired by the shell of the nautilus to create its bags Philia and Philae.               

It is associated with the mathematical sequence of Fibonacci : a sequence of intervals where each term is equal to the sum of the two numbers following it. The spirals of our DNA would also respect this sequence! 

 The eyes of the peacock's feathers arranged in a logarithmic spiral or the starfish which forms a regular pentagon directly linked with this divine proportion.

Finally, the golden ratio is also part of the human anatomy. The Fibonacci spiral can be recognized in the structure of the ear. 

The fingers also respect these same proportions!
