IN the new wave theory of matter (Einstein, L. de Broglie, Schrödinger), the material point is conceived as a singularity in a wave. More precisely, in the absence of any field of force, the wave phenomenon called ‘material point’ is represented by a sinusoïdal solution of the equation: where m0 is a constant characteristic of the wave (proper mass of the material point). The function u has a uniformly moving singularity which is the material point. If the point at rest has a spherical symmetry… CONTINUE READING
