The golden ratio (symbol is 𝜑, the Greek letter "phi") is a special number approximately equal to 1,618. It appears many times in geometry, art, architecture and other areas. page

\[\varphi = 1 + \frac{1}{\varphi} \]
So the Golden Ratio can be defined in terms of itself!

All measures, integers, points, planes, 3D structures and dynamics in the Mereon geometry are rooted in and connected by the Golden Ratio
\[\varphi = (1 + \sqrt{5}) / 2\]

We do find something ‘divine’ in the Mereon Matrix; however, it is not to be confused with a religious concept of ‘divinity’. The Matrix is based on the ‘Divine Proportion’, a section that is also known as the Golden Mean or Golden Ratio. (Dennis, McNair, and Kauffman, The Mereon Matrix, p. 46)
