Fibonacci Numbers            

The sequence, in which each number is the sum of the two preceding numbers is known as the Fibonacci series: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, ...(each number is the sum of the previous two).
            
The ratio of successive pairs is so-called golden section (GS)- 1.618033989 . . . . .
            whose reciprocal is 0.618033989 . . . . . so            that we have 1/GS = 1 + GS.
The Fibonacci sequence, generated by the rule f1 = f2 = 1 , fn+1 = fn + fn-1,
            is well known in many different areas of mathematics and science.  
Pascal's Triangle and Fibonacci Numbers            

The triangle was studied by B. Pascal, although it had been described centuries earlier by Chinese mathematician        Yanghui (about 500 years earlier, in fact) and the Persian astronomer-poet Omar Khayyám.
            
Pascal's Triangle is described by the following formula:
            
            
where             is a binomial            coefficient.
            
            
            
The "shallow diagonals" of Pascal's triangle
            sum to Fibonacci numbers.
            It is quite amazing that the Fibonacci number patterns occur so frequently in nature
( flowers, shells, plants, leaves, to name a few) that this phenomenon appears to be one of the principal "laws of nature". Fibonacci sequences appear in biological settings, in two consecutive Fibonacci numbers, such as branching in trees, arrangement of leaves on a stem, the fruitlets of a pineapple, the flowering of artichoke, an uncurling fern and the arrangement of a pine cone. In addition, numerous claims of Fibonacci numbers or golden sections in nature are found in popular sources, e.g. relating to the breeding of rabbits, the spirals of shells, and the curve of waves  The Fibonacci numbers are also found in the family tree of honeybees.

Golden Ratio & Golden Section     

In mathematics and the arts, two quantities are in the golden ratio if the ratio between the sum of those quantities and the larger one is the same as the ratio between the larger one and the smaller.
              
              
              
Expressed algebraically:
              
              
              The golden ratio is often denoted by the Greek letter phi (Φ or φ).

              The figure of a golden section illustrates the geometric relationship that defines this constant. The golden ratio is an irrational mathematical constant,approximately 1.6180339887.
                            Golden Rectangle              


A golden rectangle is a rectangle whose side lengths are in the golden ratio, 1: j  (one-to-phi),that is, 1 :  or approximately 1:1.618.
                                                
A golden rectangle can be constructed with only straightedge
and compass by this technique:
  • Construct a simple square
  • Draw a line from the midpoint of one side of the square to an opposite corner
  • Use that line as the radius to draw an arc that defines the height of the rectangle
  • Complete the golden rectangle

bila di bahagi dengan nombor sesama mereka , nilai akan di perolehi akan bermula dgn nila 1.6xxx, sehingga semakin besar nombor yg digunakan, perubahan dgn nilai terdahulu semakin kecil~~

fibonacci - susunan pada bunga , the petals tu, kan ? semua entity organic mostly, ada  mengikut  pola fibonacci

interesting actually , sophie  neveu ( da vinci ) talked about thsi with Prof Langdon, hmm...subhanallah life 's beautiful actually...kan?
god blends both arts and hard core science in such perfect harmony...superbly enchanting
