Golden Ratio
PHI = φ = 1.61803398875...
Two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger quanitity.
Given a > b > 0, (a + b)/a = a/b = φ
The golden ratio is irrational, and can be represented as (1 + √5)/2.
The golden ratio is unique in that it is the only number where the inverse of the number is equal to the number minus 1 (as in, 1/φ = φ - 1).
