SUMMARY:The Cosmological Context of Star Formation\, Astronomy Colloqu
 ium\, Tom Quinn\, University of Washington
DESCRIPTION:On the molecular cloud scale\, star formation is a very co
 mplicated<br>
\nprocess that involves gravitational collapse\, radiati
 ve transfer and magnetic fields on sub-parsec scales.  On the other ha
 nd\, there are a number of observed relationships between star formati
 on and galactic and cosmic environment such as star formation rate - m
 olecular surface density relationship in disk galaxies\, the stellar m
 ass - halo mass relationship\, and the evolution of the star formation
  rate over time.<br>
\nModeling these relationships therefore requires
  simulations of<br>
\nenormous dynamic range and well motivated prescr
 iptions for the star formation physics that is still unresolved.  Here
 \, I will describe techniques for capturing this dynamic range\, and m
 odels for star formation and its interaction with the interstellar med
 ium.  I will also describe recent successes in understanding star form
 ation histories as function galactic size\, merger history and cosmic 
 time.<br>
