Dark Matter
  I give a review of the development of the concept of dark matter. The dark
matter story passed through several stages from a minor observational puzzle to
a major challenge for theory of elementary particles. Modern data suggest that
dark matter is the dominant matter component in the Universe, and that it
consists of some unknown non-baryonic particles. Dark matter is the dominant
matter component in the Universe, thus properties of dark matter particles
determine the structure of the cosmic web.
