Abstract: Moore’s law now has worked to the point that we can simulate the nonlinear behaviour of stellar plasma with computers. Understanding the import and limitations of the results has proven challenging; the talk will describe a new physically motivated set of ideas which capture the heart of the simulations. A
survey of progress will be presented, along with connections to observations. Opportunities to seamlessly include rotation and magnetic field effects in stellar evolution will be indicated. Implications for asteroseismology, x-ray astronomy, supernova remnants, stellar evolution, core collapse, supernova explosions and related topics will be examined.
