Fibonacci
1170  1250 


Fibonacci enunciated a sequence of numbers, the Fibonacci Numbers, based on a simple arithmetic relationship.. 
In the Fibonacci Sequence (0, 1, 1, 2, 3, 5, 8,...), each number is the sum of the two previous numbers (ie: 2+3=5, 3+5=8, ...) 
Illustrating this with a series of tiles and the first few Fibonacci numbers (0, 1, 1, 2, 3, 5, 8), results in a relationship that looks like this: 


The Fibonacci Numbers and the Golden Ratio

As you go farther to the right in the Fibonacci sequence, the relationship of a Fibonacci number to the preceding Fibonacci number approaches the Golden Ratio, a ratio of approximately 1:1.618 

The Golden Ratio appears in nature, and is innate in many manmade designs, including the work of Leonardo Da Vinci, where it has been found to be prevalent in many major works.

The Fibonacci Spiral is inherent in the Fibonacci numbers and the Golden Ratio. It has been cited as a generative form in nature, describing the patterns and growth sequences of natural objects ranging from the shell of the nautilus on a microlevel, to galaxies on a macrolevel.
