These super-tiny shock fronts are triggered by point-like actuators. One-dimensional pont-like actuators cause one dimensional shock fronts. These shock fronts carry a standard bit of energy. Isotropic three-dimensional point-like actuators cause spherical shock fronts.
These shock fronts carry a standard bit of mass. In two dimensions shock fronts do not occur.
Strings of equidistant one-dimensional shock fronts constitute photons. Coherent swarms of spherical shock fronts constitute elementary particles.
Shock fronts are solutions of homogeneous second order partial differential equations. These solutions are known since the seventeenth century!!!
