Statement
My meta-golden Chi ratio is a unique mathematical constant related to the golden or phi ratio. I discovered this meta-golden Chi ratio came after nearly a decade of analyzing the geometry of composition in master paintings. Dirk Huylebrouck detailed the mathematical properties of it in Bridges Proceedings 2014. The Chi (χ) ratio, 1+√(4phi+5)/(2phi) or approximately 1.355... is a pleasing mathematical number with remarkable geometric properties similar to the golden ratio. However, instead of partitioning into a phi rectangle and a square, as in a golden rectangle, a rectangle of width 1 and a length of Chi, sub-divides into a phi rectangle and another smaller Chi rectangle.
