After reviewing some of the mathematical foundations and numerical
difficulties facing lattice QCD, I review the status of several calculations
relevant to experimental high-energy physics. The topics considered are moments
of structure functions, which may prove relevant to search for new phenomena at
the LHC, and several aspects of flavor physics, which are relevant to
understanding CP and flavor violation.Comment: Invited talk at the XXII Physics in Collisions Conference (PIC02),
