To describe Light, Newton used a Particle, which, on the one hand, is an element, invariant in space and time, but, on the other hand, whose properties depend on the Color of Light. This dependence of the property of this element is similar to the dependence of the kinetic energy of a material point on speed. But this abstract point does not have the Rest Mass invariant for all speeds. This initial contradiction was simply taken for the specificity of a given particle called a photon, which Einstein linked with the Planck's quantum of energy.
Newton's corpuscular theory of light initially encountered difficulties in describing the interference and diffraction of light. But the description of coherent light will raise the question of the size-geometry of this elementary particle. Taking into account the geometry of a photon allows us to really, and not abstractly, show its invariant specificity, which ensures the stitching not only of individual photons into a coherent wave, but also stitching of the corpuscular and wave theory. In this case, the postulated Heisenberg Uncertainty Principle is translated into the mathematical property of the Fourier transform, which determines measurability.
Moreover, Newton's Elementary Particle shows how to determine the real specificity of a material particle that has lost its Mass invariance due to its Einstein dependence on velocity and, taking into account the principle of Logarithmic Relativity, allows us to correctly systematize Elementary (Fundamental) Particles.
