  An equivalent formulation of the Riemann hypothesis is given. The physical
interpretation of the Riemann hypothesis equivalent formulation is given in the
framework of quantum theory terminology. One more power series related to the
Riemann Xi function and the Riemann hypothesis is considered. Some roots of the
polynomial connected with the power series are studied. It is shown that the
Riemann hypothesis is true. But it is undecidable and must be considered as an
axiom.
