Query: Massive Star Evolution: Binaries as Two Single Stars   Binary stars are of course more than two stars, but they are also at least
two stars. In this chapter we will review some aspects of the physics governing
the evolution of single massive stars. We will also review the uncertainties of
key physical ingredients: mass loss, rotation and convection.
