  Earlier obtained results on mechanical analogies of physical fields and
particles are reviewed. The approach rests on the concept of the substratum - a
mechanical medium, which occupies all the space and serves as a seat to support
the light and to transmit interactions. A turbulent ideal fluid was chosen for
the substratum. The turbulence is supposed to be homogeneous and isotropic in
its ground state. Perturbations of the turbulence model physical fields.
Particles originate from the voids in the fluid. Symmetrical pairs of
particle-antiparticle find analogies in mechanical pairs of
cyclone-anticyclone. A quantum particle is modeled by the dispersion of a point
discontinuity (defect) in the stochastic medium. Gravitation relates to
emitting by defects the continual flow of the transient point dilatation. The
shock wave mechanism of the re-collection a discontinuity in the incompressible
medium governs such phenomena as the "wave function collapse" and instantaneous
quantum correlations. Microscopically, the electromagnetic wave and gravitation
are modeled by the torsional and axisymmetric waves, respectively, in the
vortex sponge.
