De Broglie Interval Wave and Heisenberg's Uncertainty Principle.

In this work a more accurate interpretation of de Broglie waves as interval waves is given, i.e., spatio-temporal waves. Also given a strict derivation of the Heisenberg's uncertainty principle from the de Broglie interval wave, that is, from wave-particle duality, is given. Proven that that the uncertainty principle expresses the fact that in the microworld our concepts (length, time, etc.) are not fundamental, and therefore they can change in a certain way. The problem of the radius of an elementary particle is also logically explained.
