...encrypted in the pentagram (too long title).
This journal entry is an explanation for this one:
The pentagram/pentagon is based on the golden ratio. The grid in this picture is one of Penrose's mosaics, also derived from the golden ratio. The positions of the nodal points are not random.
There is nothing mystical here. Or no, on the contrary, it is the deepest mystery over which the greatest minds of the past fought and never solved it. For example, Johannes Kepler was looking for a mathematical formula for the harmony of the Universe all his life. He did not find it, but as a by-product he became one of those who founded modern science. (by the way, Penrose's mosaics are based on Kepler's ideas).
If you learned to draw at art school or from books, you know what composition is. This is a set of rules, it is advisable to use them when creating a picture, so that it looks "complete". Now do a thought experiment. In the countryside, just look to any side of the horizon. Now evaluate what you see as a landscape. As if it were a painting. There is a composition there. The question is: who did apply the composition rules to the random point where you stand and to all the random set of things that you see (trees, clouds, landforms, etc.)? That is, a person who draws poorly can paint a landscape "with non-compliance with the composition", but in nature there is no such "bad landscape" and cannot be? Why?
