“Ratio of God”

We can find out beauty in nature, historic landmark, art and music.
A constant ratio exists there.
From time immemorial, people have been calling it "GOLDEN RATIO".

When you cut off a segment whose length is given by x
from a segment of the unit length,
the ratio of the unit length to x is equal
to the ratio of x to remain.
The ratio is 1.618033988... : 1.
This is the GOLDEN RATIO.

The GOLDEN RATIO guides you make beautiful figures in manufacturing.
GOLDEN RATIO CALCULATOR leads to the miraculous ratio
that ancient artists discovered with their sensibility.
Kazuo KAWASAKI, design director and doctor of medical science, invented this application.

All sales of this application are used
for Peace-Keeping Design (SDwave, NPO).

1. Select textbox in which you want to set the length.
2. Input an arbitrary length, and you will get the GOLDEN RATIO.
3.You can select the figure where GOLDEN RATIO is led
by flicking the screen by your finger.
