From the Foucault pendulum to the galactical gyroscope and LHC
  We consider the Foucault pendulum, isosceles triangle pendulum and the general triangle pendulum rotating on the Earth. As an analogue, planet orbiting in the rotating galaxy is considered as the giant galactical gyroscope. The Lorentz and the Bargman-Michel-Telegdi equations are generalized for the rotating system. These equations are inevitable for LHC where orbital photons "feels" the Coriolis force caused by the rotation ofthe Earth.
