This paper outlines key problems in the theory of atomic collisions at ultracold temperatures. Features associated with the unusual energy time and distance scales encountered in ultracold collisions are described. The molecular physics of excited plus ground state alkali dimers is examined. A quasistatic model is developed to describe collision rates between normal and ultracold temperatures. Mechanisms are proposed for the very different associative ionization rates observed in an optical trap and in optical molasses. (AIP)
