Heisenberg incertitude principe ? contradicting ?

[fleem]

So in conclusion is there really inderteminism ? Or does it just appear as inderteminism to us because we cannot yet find any logic behind it ?

- If the theory of hidden variables is true, it would mean no ?
- If nature can produce true probability based random numbers it would mean yes ?

Correct. We don't know what really happens. It might even be that what really happens is something our classical brains can never understand, although I hope that isn't the case! QM says nothing about what really happens, it just let's us predict the statistical (and classical) results of experiments.
