Dear Friends,
Next we will use our quantum vacuum mechanics theory to solve the problem in the conventional quantum mechanics theory, and the first example is the famous Heisenberg’s uncertainty principle, which state that “It is not possible to determine both the position and the momentum of a particle with unlimited precision”.
Once, R. P. Feynman has said that “the uncertainty principle protects quantum mechanics”!Heisenberg recognized that if it were possible to measure the momentum and the position simultaneously with a greater accuracy, the quantum mechanics would collapse. The only question is why it is so, or what is its mechanism?
To answer the question, we will startwith “wave packet” such as photonin classical mechanics, which is a portion of a continuous wave train as shown in the diagram of fig. 3 (a), then what we got is the relation between length x and wave number k is as (1) below.
∆x. ∆k ~ 1 …. (1), ∆k = (2¶/h) ∆p …. (2), ∆x. ∆p ≥ (2¶/h) ~ h …. (3)

If we reduce ∆x then ∆k is increase, and in the reverse when we reduce ∆k then ∆x is increase. This means that we cannot determine both the position and the wave number of a wave packet with unlimited precision! So this istheuncertaintyprinciple in classical mechanics which is occurreddue tothe property of wave packet!
Now by apply the uncertainty relation of wave packet (1) to electron wave via “single-slit diffraction” experiment in the diagram 3 (b). Consider a beam of electrons of speed v pass through the slit and create diffraction pattern as shown. By relating the parameters; v, ∆v, ∆x and Ө. Together with de Broglie wavelength λ = h/p or (2), then what we get is ∆p.∆x ~ h. (3).
In conclusion, we could see that the uncertainty measurement of electron is due to the co-moving wave packet (of vacuum medium) created by the moving electrons. And the energy of the wave packet will guide the moving electrons forming to be the interference pattern. This is the mechanism of Heisenberg’suncertainty principle!
It is interesting to note that if there were no vacuum medium, then the moving electrons cannot create electron wave. So the moving electrons will go straight pass though the slit direct to screen and pile up as a smooth curve (due to statistical randomness, not interference) as shown at the top of the diagram 3 (b). So in principle, we can make a measurement of electron with unlimited precision!
Sincerely,
Nimit
