Golden Mean Calipers (Gisborne)
The Golden Mean? What’s that?
The Golden Mean (also called The Golden Ratio, Phi, The Divine Proportion) is a simple ratio (1 to 1.618) that is considered aesthetically beautiful, and which has been used in art and architecture for thousands of years. It frequently turns up in nature and in the human body… particularly the human face… which could go some way towards explaining its popularity in art. How it came to feature so greatly in human physiology is a bit more of a mystery.
What do Golden Mean Calipers actually do?
They open/close a bit like a compass or divider… the ratio of the distance a to b is always The Golden Mean : 1.618 to 1. In addition to this, the ratio between a, and whole width… a+b, is also The Golden Mean.
