The goal of this course is to present an introduction to fundamental plasma physics and magnetohydrodynamics, beginning with kinetic theory. The various important limits including the vlasov equation and magnetohydrodynamics will be derived. Applications will be mostly from astrophysics and the solar system. These will include the main dynamical processes in the solar atmosphere, interplanetary medium, magnetospheres, interstellar medium, blast waves, accretion disks, etc. The emphasis throughout will be on basic physical processes and the various approximations used in their application to concrete problems.
