## What is the Fibonacci Sequence?

* The Fibonacci equation, the Golden ratio:* This rule states that an outcome depends on its previous two predecessors. These outcomes are the numbers of the Fibonacci sequence. It’s a pattern that constantly repeats itself; a pattern that can be seen in our every day lives.

0+1=1

1+1=2

1+2=3

2+3=5

3+5=8

5+8=13

8+13=21

…and so on

The rectangle diagram represents what happens when we assign the digits to the side dimensions of squares. When repeated, we get the square pattern. When the squares are connected with an arch, we get the Fibonacci spiral. This sequence continues on forever, as does the spiral.

The spiral, or portions of the spiral, are seen in familiar places in nature and even your kitchen. Seed heads, Phyllotaxy, kernels. Plants do this to form optimal packing. No space is wasted and crowding is eliminated when it’s formed this way.

While flowers don’t show the Fibonacci spiral, they do fit the sequence. The number of petals on a flower, as well as the leaf patterns, is one of the Fibonacci numbers. Wild field daisies flower with 34 petals, while the typical flower shop daisies petal in a variety of 13, 21, 34, and sometimes even 55 or 89. Ferns often uncurl in the form of the Fibonacci spiral. More leaves are located further in the curl, while the thicker part of the stem is further outside.

The ratio between the parts of your hand are easy to see. While every human isn’t perfect, human proportions roughly follow this example of the Fibonacci sequence. This pattern continues past the hand, up your arm and elsewhere in the structure of the human body.

*Take a look at your body: *

- The length of your foot is the same as the length of your forearm; between your wrist and elbow.

- The distance from your navel to knee is the same as the distance from your knee to the tip of your toes.

- The distance from fingertip to wrist is the same as the distance from wrist to elbow.

- The distance from fingertip to elbow is the same as the distance from ankle to knee.

- Your wingspan is the same length as your height.
