Square heads or square symmetries are not two-headed monsters but drill bits in the shape of a perfect square that simultaneously allow the implementation of strength and durability for high-speed electrically powered machineries. On the other hand, diamond heads are drill bits reinforced with the hardest substance found on earth, diamonds. The crystalline structure of diamonds is carbon atoms arranged on the vertices of perfect regular polyhedron belonging to the five Platonic solids called a tetrahedron. Furthermore, it is formed by connecting the six face-diagonals of a perfect cube, another Platonic solid. The three others Platonic solids are icosahedron, octahedron, and dodecahedron.

In the world of carbon atoms, to have and to have not are the insider world of organic matter and the outsider world of the inorganic matter. The mesosphere of human beings belongs to the group of organic matter which is actually a subgroup of all living matter. Living matter depends on the square head symmetry of the four bases of DNA organic molecules plus one similar structure found in all RNA organic molecules: adenine, cytosine, guanine, and thymine which is replaced by uracil in RNA organic molecules.
