A short review of the results of analytical and numerical investigations of Langmuir turbulence is given. The presented theory of the strong electrostatic turbulence is based both on the concept of Langmuir collapse as a nonlinear stage of modulation instability and on the results of computer experiment which provides a continuous transition from the collapse concept (concentrated in averaged dynamical equations) to conditions of an actual experiment sufficiently well described by Vlasov equations.
