    Re: difference between Golden Mean Grid and The Golden Ratio?

    Hi cosi,

    The Golden Ratio is found in many of life's arenas including Math, Physics, Nature, Music, and Art and is otherwise called
    'Phi' after the greek letter phi. It is a ratio whos inverse is located approximately 2/3 of the way through whatever piece of
    music one is listening to. In art the ratio usually refers to the proportions of length:heigth of a painting. The exact ratio
    is defined as (1 +or- sqroot 5)/2 or approximately 1.618033989. The inverse is also approximately .618033989 which is
    near the 2/3 mark mentioned earlier.

    The Golden Mean Grid I am hearing about here for the first time and have less of an idea about but will nonetheless take a shot
    at giving my notion of what it means. The few google sites I see seem to be talking about a grid made up of golden ratioed
    rectangles arranged in simplified 3 by 3 grids approximating length and width divisions into thirds.

    Hope this helps!
