WHERE DOES THE UNCERTAINTY PRINCIPLE COME FROM (by other words, why in the equation delta(x) x delta(p)=hbar, the value of hbar is NOT zero.

Once again: I know experiments, history, etc. Moreover, I know that the uncertainty principle is just a mathematical propery of waves (and everything is wave on fundamental level): Fourie transform of the length of wave (position uncertainty) is simply the wave number range (uncertanty of momentum) and vice versa, so the shorter the wave bunch (the more precize is the position)the blurrier the wave number (the less precise is the momentum).

And, this, by the way has nothing to do with any measurements, it is just a math of Fourie transformation.

So, I know how waves work and thus what is the math behind all of this.

I want to know, WHY hbar ir NOT zero - WHAT IS THE MATHEMATICAL ORIGIN of non-zero hbar. Where does it come from? Or, by other words, WHY on the fundamental level things are waves with CERTAIN NONZEROBAR relationship between position and momentum?

Again, MATH IS ALWAYS CORRECT, and uncertainty principle has nothing to do with measurements as you described above. Sorry.

So, where does uncertanty principle come from?
