Traditional Culture and Golden Section

For example, some people say that the navel is the golden section.

Then upper body/lower body = lower body/total height (the latter half is higher than the upper body)

The ratio of upper body/lower body calculated from this is called golden ratio, and navel is called golden section.

It can be calculated from this equation: let the upper body be x and the lower body be 1.

X/ 1= 1/( 1+X)

x？ +X- 1=0

The ratio of X=(√5- 1)/2 is about 0.6 18.
