4. The problem is that: • According to its definition, function H must be the total energy of the mechanical system gained in the duration of time from t0 to t1. Should we understand this as cause or consequence? Is it actionor effect? • What if the action doesn’t reach the least action threshold? • What could the mechanical energy state of the micro objects under the action of external force be if this least effect is taken into account? • Is the so called “wave-particle dualism” the cause of orbit quantization of electrons in atoms or do they both have other similar causes because they are both associated to Planck constant?

5. II. BASIS CONCEPTS.1. Effect of and action among physical objects.

7. 2. Least effect and least action. As recognized above, there cannot be any effect smaller than the h leasteffect value. This also means that H effect function pursuant to (4) is not continuous and it can only be the multiple number of h: H = nh, (n = 1, 2, 3,…) (8) On the other hand, any occurring physical processes are associated with the energy exchange. That exchange occurs on every small portion. Thus, corresponding to the least effect h is the least action d. h = d. (9)

8. III. THE LEAST ACTION PRINCIPLE "For a physical object to change its energy state, the action on it can not be smaller than the least action". t1- D =  2E(t)dt  d = h/ (10) t0- If E(t) = E = const and  = 1 then: D = 2E(t1- t0) = 2Et h (11)

9. This action time interval ∆t can not be too long and must be limited by some conditions: - In case the living time of the given object is equal to τ1, ∆t  τ1; - In case the possible time interval for the two objects to exchange their energy is equal to τ2, ∆t  τ2 ; - In case the object under the action is moving in the period of T, ∆t  T

34. IV.CONCLUTION 1. According to LAP, the fundamental particle can merely move in “jerky steps” varying its velocity along with each step, but not in regularly increasing or decreasing manner. 2. The “physical wave” does not exist! The particle just has “wave-like manifestation”, but not “waveproperty”. There is a new invention of the particle’s property, that is: "The particle’s movement can be only deflected at limited and specified angular quantum and that can not be as small as wanted ".

35. 3. In case the movement deflection of an electron in atoms occurs under the action of Coulomb force at uniform angular quantum whose sum is multiplication of 2, the electron’s orbit has a shape of a regular polygon inscribed to a circle with radius rn, from which the orbit quantization condition of electron in atom can be formed.
