Radiatively Driven Winds of OB Stars -- from Micro to Macro
  We review basic physics of line-driven stellar winds of OB stars. We discuss elementary processes due to which stellar winds are accelerated on a microscopic level. We show how these microscopic processes may enable the outflow and how they determine wind properties on a macroscopic level. We discuss shortcomings of present wind theories and future wind model improvements.
