If you enjoy math, geometry,
mystery and science, this subject might interest you. It is too complex for a
simple blog post. Here are some highlights and I will include links if you find
this subject as intriguing as I did. Enjoy.
Phi, also known as The Golden Ratio or Divine
Proportion, Golden Section, Golden Mean, is represented by the number 1.61803399. The digits can go on
forever without repeating. We will simplify it to 1.618.
The Fibonacci Sequence is nature's numbering series and provides another
way to derive Phi mathematically. The sequence of numbers is quite
simple. Starting with 0 and 1, each new number in the sequence is simply the
sum of the two before it, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.
The approximate ratio of each successive pair of numbers in the sequence is
1.618 or Phi. (Example: 5 divided by 3 = 1.666.) As you
go further into the sequence and more digits are added, the ratio gets closer
to the exact figure of Phi.
Both The Fibonacci Sequence and Phi
represent the same number, 1.618, therefore they are inseparable. When Phi
is mentioned, know that The Fibonacci Sequence is also there.
Why
were the early Greek and Renaissance artists, scientists, architects, musicians
and astronomers so fascinated by this number? Why did Dan Brown use Phi
as a plot element in his novel, The Da Vinci
Code? Why do we still use Phi today?
“Phi creates a sense of balance, harmony and beauty in the
designs we find throughout our natural world and the universe thereby creating
a sense of harmonic relationships and spiritual connections.” Since ancient times, man has applied both Phi
and The Fibonacci Sequence consciously and unconsciously to
achieve balance, harmony and beauty in art, music, architecture, design and
religion.
The influence of Phi may be seen in the works of the early
artists such as Da Vinci, Raphael, Botticelli and Seurat, right up to present
day artists. Musical scales and compositions and the dimensions of musical
instruments, such as the violin, all show the influence of Phi.
Architecture, such as the Notre
Dame in Paris and the Greek and Roman Temples are another example. Industry
uses Phi in the design of their logos and products, such as cars and
fashion. In medicine, Phi is used as a guide in both facial plastic
surgery and cosmetic dentistry.
The Fibonacci Sequence and the influence of Phi
appear everywhere. In nature they are is seen in the leaf and petal
arrangement in plants and flowers, the bracts of a pinecone, the scales of a
pineapple, the arrangement of seeds in a sunflower. Many insects and animal
dimensions are based on Phi, such as the spirals of seashells, the body sections of ants and other
insects, wing dimensions, etc. Even in the arrangement of the bones of our hands
and the spirals of human DNA.
Astronomers
have found Phi and the Golden Ratio relationships in our solar
system and the universe.
We
didn’t invent Phi or The Fibonacci Sequence. It was always there.
It is as old as the universe. Some Theologians believe that Phi is
linked to the Creation.
Pretty interesting reading.
