a + b 

Is to a

As a is to b.

A golden rectangle with longer side a,

And shorter side b, 

When placed next to a square 

With sides of length a, 

Produces a similar golden rectangle,

With longer side a + b,

And shorter side a. 

This  mean has been applied

Throughout history, 

The Pyramids,

Pythagoras,

Euclid, 

Da Vinci,

Kepler,

Fibonacci,

Bartok,

Penrose.

The Swiss architect,

Le Corbusier knew this,

Le Corbusier lived this,

Le Corbusier produced this perfectly

In the Villa Stein.

The golden mean,

Or phi – Φ.
