  The basic stages of development of the theory of superconductivity are
traced. Despite of remarkable successes of theory, the physical explanation of
the phenomenon of superconductivity - of the not fading electrical current in
dissipative medium - is not exists until now.
  In the present paper on the basis of works (Klimontovich, 1990abc, 1999) the
physical explanations of this phenomenon is considered. Will be show that the
existence of not fading electrical current becomes possible due to occurrence
of flicker noise and appropriate residual temporary correlations.
