Abstract Kinetic theory of gases is a classical subject in non-equilibrium statistical physics and applied mathematics. Nowadays, however, gases in non-equilibrium conditions play important roles in many fields, such as micro fluid dynamics and vacuum technology. Kinetic theory of gases is a principal tool to deal with the behavior of such non-equilibrium gases, since it is beyond the applicability of ordinary fluid dynamics. In the present talk, a brief introduction to kinetic theory is given first. Then, its application to some basic problems, such as the approach to equilibrium of a gas and a simple model of the Crookes radiometer, is discussed.
