Special relativity (in Russian)
  A modern elementary introduction to special relativity for advanced school children or first-year university students, in Russian. I try to demonstrate that relativity does not contradict common sense; on the contrary, it follows from common sense logically. I discuss Minkowski space-time geometry in some detail. Geometrical approach, with few simple formulas but many pictures, makes results of the theory intuitively obvious.
