  Low-frequency 1/f-noise occurs at all levels of the nature organization and
became an actual factor of nanotechnologies, but in essence it remains
misunderstood by its investigators. Here, once again it is pointed out that
such the state of affairs may be caused by uncritical application of
probability theory notions to physical random phenomena, first of all the
notion of "independence". It is shown that in the framework of statistical
mechanics no medium could provide an inner wandering particle with quite
certain value of diffusivity and mobility, thereby producing flicker
fluctuations of these quantities. This is example of realization of universal
1/f-noise origin in many-particle systems: dependence of time progress of any
particular relaxation or transport process on the whole system's detailed
initial microstate
