The Fibonacci sequence is named after Leonardo of Pisa, who was known as Fibonacci (named after, he did not discover). Fibonacci’s sequence was first introduced to the western world in 1202 by Fibonacci, the sequence had been noted by Indian mathematicians as early as the sixth century.

The fibonacci also defines how the density of branches increases up a tree trunk, the arrangement of leaves on a stem, and how a pine cone’s scales are arranged. Yet you will not see the fibonacci everywhere, as nature has many different methods and shades of survival.

The fibonacci spiral appears not only in the perfect nautilus shell,

but in events and objects viewed from a far. An energy system in the shape of a fibonacci moves with limited losses. Hurricane Irene.

The fibonacci as some of the largest structures in the universe. Spiral galaxies are the most common galaxy shape. Galaxies group together in superclusters and superclusters group together in walls. Currently the largest known structures are these walls or filaments of numerous superclusters that are gravitationally bound and separated by large areas of void. The Milky Way’s dust obstructs us from seeing the depth of these filaments or sheets, so we do not yet know the exact shape of these walls.

The fibonacci appears in the smallest, to the largest objects in nature. It is a way for information to flow in a very efficient manner. Here, a microscopic view of the ovary of an Anglerfish.

The mathematics of the golden ratio and of the Fibonacci sequence are intimately interconnected. The Fibonacci sequence is a recursive sequence, generated by adding the two previous numbers in the sequence.: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987…

If you were to draw a line starting in the right bottom corner of a golden rectangle within the first square, and then touch each succeeding multiple square’s outside corners, you would create a fibonacci spiral.

Water falls into the shapes of a fibonacci during numerous events. Another example would be a vortex.

One blogger has applied the fibonacci sequence to population density and land mass. In Africa the majority of highly populated cities fall on or close to where the spiral predicts.
