The number 1,6180339887… was known and used in the Renaissance as the Divine Proportion and even before by the Greeks.
Here's a geometric calculation:
To me, to make a long story short, it means that when I have to find the right place for something important, I’ll find the middle section and then move a bit to the right or to the left. This something important can be a rock, a coral or, most important of all, empty space. If I have to divide a rock layout in two structures, I normally avoid dividing right in the middle, but instead make the split a bit to one side.
You will find this number in the proportions of the human body and of many other animals, plants, DNA, the solar system, art, population growth and stock market, just to name a few examples.
We seem to find its presence pleasing to the eye. In this example by Ralf Lindberg we can see that the large rock in the back, which is the centerpiece of the tank, is no exactly in the middle but a bit to the right side
Once again, this is just a starting point. There are many other circumstances to take into account when deciding where exactly to make the section cut and in the end it will be your eyes that will tell you where’s the best
