The golden mean has been used in art and architecture for thousands of years. It is frequently found in nature, in the proportions of the human face, in the spiral patterns of leaves and flowers, it is a basic universal mathematical constant.
It is also known as The Golden Ratio, Phi, and The Divine Proportion.
