  The top quark is one of the least well-studied components of the standard
model. In these lectures I discuss the expected properties of the top quark,
which will be tested at the Fermilab Tevatron and the CERN Large Hadron
Collider. I begin with a modern review of the standard model, emphasizing the
underlying concepts. I then discuss the role the top quark plays in precision
electroweak analyses. The last two lectures address the strong and weak
interactions of the top quark, with an emphasis on the top-quark spin.
