  These are three lectures given at the ``Lake Louise Winter Institute", (Lake
Louise Canada, Feb 1993). A pedagogical introduction is given to attempts to
formulate a more fundamental theory of elementary particles than that provided
by the standard model. After a review of the basic elements of the standard
model, its unsatisfactory features, and ideas to modify them will be discussed.
An introduction to Technicolour, t-quark condensates, supersymmetric models,
GUT's and a brief comment on composite models follow.
