DESCRIPTION: In spite of a rich and interesting history over the last 400 
 years or so\, the general three-body problem in Newtonian gravity remains 
 unsolved.  The reason for this is chaos.  But what is chaos\, and why is i
 t such a challenge to address in modern physics research?   Ironically\, i
 t was chaos that made finding an analytic solution such a headache in the 
 first place\, and it is chaos that is presently impeding the advancement o
 f our understanding of basic dynamics problems whenever using numerical si
 mulations to perform the experiments.  After reviewing the basic principle
 s of a chaotic dynamical system\, I will explain why this is the case usin
 g examples from the gravitational three- and four-body problems.  If there
  is time\, I will review what we know regarding binarity in galactic nucle
 i\, and also present a project on cirbumbinary disk evolution in triple st
 ar systems and the three- and four-body problems in AGN disks.
