The Golden Ratio, the perfect number in mathematics, is the squareroot of 5 plus 1, divided 2.
(Sqrt(5)+1)/2 = 1.618033988749895
Interestingly, It's the only number that if squared, is equal to itself plus one. In other words, Phi^2 = Phi+1. And if you took it's reciprical, it's equal to Phi-1. Phi^-1 = Phi-1.
