Query: A possible new approach of quantum measurements   It is proposed a possible new approach of quantum measurements (QMS),
disconnected of the traditional interpretation of uncertainty relations and
independent of any appeal to the strange idea of collapse (reduction) of wave
functions. The new approach regards QMS as a statistical samplings (but not as
simple detection acts) and their description as a distinct task, independent of
actual procedures of quantum mechanics. A QMS is described by means of
transformations of probability density and probability current, from intrinsic
into recorded readings. The quantum observables appear as random variables,
described by usual operators and valuable through probabilistic numerical
parameters (mean values, correlations and standard deviations). The values of
the respective parameters are not the same in the two mentioned readings. Then
the measurement uncertainties (errors) are described by means of the changes in
the alluded values. The new QMS approach is illustrated through an
one-dimensional example.
