    5  Galaxies can be described in terms of their structure, dynamics
    6  and stellar populations.  Some very robust correlations between
    7  various galaxy structural properties, such as total luminosity,
    8  maximum circular velocity, and size have been known for many
    9  decades yet still lack a theoretical explanation!  A fundamental
    10  challenge to understanding these scaling relations, and ultimately
    11  galaxy formation and evolution, is the elusive interplay between
    12  visible and dark matter.  I will discuss the latest derivations
    13  of galaxy scaling relations and our attempts to understand them.
