What is the golden ratio?The golden ratio is a special number which can be defined in terms of itself. It is represented by the 21st letter of the Greek alphabet which is phi. It is found by dividing a line into 2 seperate parts, so the longer part divided by the smaller part is equal to the whole length of the line divided by the longer part. How does it relate to the Fibonacci Sequence?When you take 2 successuve Fibonacci numbers their ratio comes close to the golden ratio being 1.618. The bigger the pair of Fibonacci numbers used the closer the aproximation to the golden ratio.

There are patterns of 5 all throughout the human body, which is the basis of phi. We have 5 appendages on the torso, in our arms, leg and head. We have 5 appendages on each of our hands and feet. There is 5 opening on the face. The human body also consists of 5 sense organs being sight, sound, touch, smell and taste.

Each section of the index finger, from the tip to the base of the wrist is larger then the one before it by about 1.618 being the golden ratio. The ratio of the forearm to hand is equal to phi.

Both front incisor teeth form a golden rectangle, using the phi ratio in both width and height. The ratio used in the width of the smile from the 3rd tooth from the center is phi. As well as the ratio of the width from the first tooth to the second tooth from the center is also phi.

The foot contains multiple proportions based on the lines of phi. In the diagram to the left it shows the serveral sections. 1.the middle of arch of the foot2.the widest part of the foot3.the base of the toe line and big toe4.the top of the toe line to the base of the index toe

If you graph the ratio of each successive pair of Fibonacci numbers the graph comes out similar to the EKG pattern of the human heartbeat. A heartbeat that produces a phi relationship in the T point of the ECG represents a state of being one of health, peace and harmony.

The number that shows up everywhere in the human body from the length of the arms and legs compared to the torso is the golden ratio. Artists and sculptors have used the golden ratio to create work of the ideal human figure.

The golden ratio proportions are spread out throughout the whole human face. The proportions are from the center of pupil:bottom of teeth:bottom of chin, outer & inner edge of eye:center of nose. Outer edges of lips:upper ridges of lips. Width of center tooth to the width of the second tooth and width of the eye to the width of the iris.

If you take the phi point of .618 or 37 degrees centigrade which is the average of human body temperature, you get 23 degrees centigrade or 73 degrees Farenheit which is room temperature.

The DNA molecule is based on the golden section. It measures out to 34 angstroms long by 21 angstroms wide ofr each cycle of its double helix. Both 34 and 21 are numbers of the Fibonacci series and their ration comes out to be 1.6190476 which approximates phi, 1.6180339.
