  These lectures are intended for graduate students who want to acquire a
working knowledge of path integral methods in a wide variety of fields in
physics. In general the presentation is elementary and path integrals are
developed in the usual heuristic, non-mathematical way for application in many
diverse problems in quantum physics. Three main parts deal with path integrals
in non-relativistic quantum mechanics, many-body physics and field theory and
contain standard examples (quadratic Lagrangians, tunneling, description of
bosons and fermions, quantization of gauge theories etc.) as well as
specialized topics (scattering, dissipative systems, spin \& color in the path
integral, lattice methods etc.). In each part simple Fortran programs which can
be run on a PC, illustrate the numerical evaluation of (Euclidean) path
integrals by Monte-Carlo or variational methods. Also included are the set of
problems which accompanied the lectures and their solutions.
