Fibonacci, Leonardo of Pisa

Leonardo of Pisa was born in Pisa, Italy in 1170. He was considered as “the most talented mathematician of the Middle Ages.”  He invented the Fibonacci Sequence. The Fibonacci Sequence of numbers means each number after the first two is the sum of the previous precious two numbers. As my point of view, I think it creates parrtens. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…

The higher up in the sequence, the closer two consecutive numbers of the sequence divided by each other will approach the Golden Ratio which I think is significant. The Golden Ratio can apply to any of arts. Many artists and architects have proportioned their works to approximate the Golden Ratio. The Golden Ratio is approximately 1.6180339887.

The golden section is a line segment sectioned into two according to the golden ratio. The total length a+b is to the longer segment a as a is to the shorter segment b.

The golden section number is closely connected with the Fibonacci series and has a value of (sqr5 + 1)/2

Golden Proportion,














One of the most spectacular examples of the Fibonacci Series in nature is in the head of the sunflower.
Scientists have measured the number of spirals in the sunflower head. They found, not only one set of short spirals going clockwise from the centre, but also another set of longer spirals going anti clockwise, These two beautiful sinuous spirals of the sun flower head reveal the astonishing double connection with the Fibonacci series.
