  In this work we consider basic principles and problems of the standard
quantum mechanical formalism. Especially we consider final detection procedure
(collapse) as a quantum-classical continuous phase transition with spontaneous
(non-dynamical) unitary symmetry (superposition) breaking (effective hiding).
Practically, collapse as an effective (non-absolute) phenomena can be
considered as an especial case of the general formalism of spontaneous symmetry
breaking (with applications in many different domains of the physics, e.g. in
elasticity of rigid bodies, quantum theory of ferromagnetism, quantum theory of
electro-weak interactions as well as in chaotic inflation cosmology). General
theory of the detection procedure (collapse) we consider in real experiment of
single photon interference at beam splitter with final detection of the photon
coordinate by usual photographic plate.
