PHI refers to the golden ratio or ' Proportia ' Divina (divine proportion). The golden section is a piece of ancient enigmatic mathematics. The number indicates a special relationship of line segments, and is abbreviated with the Greek letter φ (pronounced ' Fie '). The golden ratio turns up in all kinds of unexpected places, in nature as well as the human body. Also in architecture many manifestations can be found.

PHI Notes is a Social Enterprise! The current societal challenges ask for a different economic approach. An economy that works for people: circular, poverty-free and inclusive. Foundation Social Enterprise NL connects entrepreneurs who act differently, entrepreneurs who aim to create social added value.
