## Fibonacci’s Spiral

This piece of art is designed to draw the observer into contemplating the beauty of mathematics in nature. It illustrates the theoretical growth of an ammonite using the mathematical Fibonacci Sequence which is rendered in tile. The Fibonacci numbers, when represented by proportional squares scribed with quarter circles and then stacked successively, form an equiangular spiral. This spiral resembles the logarithmic spiral which gets wider every quarter turn by a growth factor equal to the golden ratio, f = 1.61803. Spirals appear in nature as the exoskeleton of a shell, the curl of a wave, and in the arrangement of seeds in a sunflower and flowerlets in a pineapple. Spiralling allows for close packing, which is an efficient use of space.

I have chosen to represent this concept pictorially using tiles stacked successively to mimic the beauty of the ammonite spiral imbedded in the art. These ammonite fossils are all unique, spectacular, natural and very old, approximately 250 to 400 million years old.
