The Run I experiments at the Fermilab Tevatron Collider discovered the top quark and provided first measurements of many of its properties. Run II (and eventually the LHC and NLC experiments) promise to extend our knowledge of the top quark significantly. Understanding the top quark's large mass, and indeed the origin of all mass, appears to require physics beyond the Standard Model. Thus, the top quark may have unusual properties accessible to upcoming experiments.
