Query: Massive Star and Star Cluster Formation   I review the status of massive star formation theories: accretion from
collapsing, massive, turbulent cores; competitive accretion; and stellar
collisions. I conclude the observational and theoretical evidence favors the
first of these models. I then discuss: the initial conditions of star cluster
formation as traced by infrared dark clouds; the cluster formation timescale;
and comparison of the initial cluster mass function in different galactic
environments.
