The Fibonacci series is also a natural phenomenon that gives shape to
many living things and that forms the basis for the Golden
Proportion. Humans seem to find this proportion universally pleasing
and therefore the use of Fibonacci proportions is a natural and easy
way to create structures that "work" aesthetically.
P.S. The Fibonacci series (1, 1, 2, 3, 5, 8, 13, 21...) is formed by
adding two consecutive terms to derive the next term in the series
(therefore 13 + 21 gives the next term 34). The Golden Mean (or
Golden Proportion or Ratio) may be approximated by dividing
consecutive Fibonacci numbers (13/21 = 0.61905..., 21/13 =
1.61538...).
The higher up the series the closer the approximation to the
proportion, which is commonly represented as "phi" and equals
1.6180339887499... or -0.61803398874989... For more details and an
explanation of why phi has two values, see:
