  We discuss prospects for detecting the two charm-related phenomena of
$D^0$-${\bar D}^0$ mixing and weak radiative decays of $D$ mesons ({\it e.g.}
$D\to K^* + \gamma$). A general update of particle-antiparticle mixing for the
pseudoscalar mesons is presented and the dynamics of mixing is reviewed, with
application especially to the $D^0$-${\bar D}^0$ system. The radiative weak
decays of $B$ mesons is then considered, and the problem of hadronic
uncertainties is reviewed. Finally, the technique of calculating radiative weak
decays for charm mesons is explained.
