Query: 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.
