in mathematics there is no exact definition of a circle.
as well as accurate determination of the radius.
A circle is a lot of a square - where there are 35 thousand angles. And it can be complicated endlessly. But what if we simplify the circle and radius? There will be just 3 sides.
Here, see for yourself, the circle can complicate the infinite a lot. By adding facets. But the simplest circle model is the triangle.
I want to assume that the stable radii of atoms are also triangular. A visible radius (an atom is a bluff and a mirage)
I also made a simple 2D triangle folding simulation. And I related them to round radii that do not affect each other, and interesting images turned out.
Here, see for yourself
My suggestion is that this could simplify molecular modeling and solve the problem. After all, the simplest model of a circle is a triangle.
Previously, in the era of optical tubes, scientists saw channels on Mars. But with the creation of an exact technique, these channels turned out to be mirages and optical distortion. as well as all the long-term observed radiation of an atom, can be mirages.
