Phi in Nature

Curious name Phi! Why Phi?

Phi is a symbol of mathematical progression which is recognised throughout architecture, the arts and nature where it is esteemed as a measure of balance, proportion and beauty. We see it in the spirals of a sunflower, the curve of a Nautilus shell (on which our logo is based), the columns of the Parthenon and in the rhythm and construction of music.

Phi is also the Greek symbol used for the denotation of flux (lumens) in lighting and many would recognise the circle with the vertical line. We concluded that this positive relationship between people, science, nature, architecture and light fitted perfectly with our intentions and Phi was then the obvious metaphor.


Our site has some interesting images in relation to Phi, we hope you like them.
