Query: On the world cognizability   The paper gives a few examples of the phenomena that will never be understood
by the mankind. The first example is the physics at the scales of $\sim
10^{-33}$ cm where the gravitation interaction becomes strong, sales at the
very beginning of the Big Bang. It argues that the mankind will never establish
the laws that controls the events at these scales. Further, it is supposed that
the time dependence of the entropy, which determine the direction of the time
arrow, originates at the same time scale and, thus, the nature of the time
arrow will be never established either. Finally, I conjecture that the brain
cells are controlled by quantum computer with the very large (or even infinite)
number of degenerate states. An external observation destroys this degeneracy,
leading to impossibility to understand the mechanism of the conscience.
