The Golden Ratio

The Parthenon in Athens, the Pyramids of Gaza, even Nature's rose petals and the arms of a starfish, are all constructured around a number known as the Golden Ratio which is 1 plus the square root of 5 divided by 2 or 1.618033988------ an irrational number with decimals which go on forever without ever repeating in a pattern. Objects so constructed are visually pleasing to the human eye.
