Editing Dynamical systems theory (section)

=== System dynamics ===
:[[System dynamics]] is an approach to understanding the behaviour of systems over time.  It deals with internal feedback loops and time delays that affect the behaviour and state of the entire system.<ref name="sysdyn">[http://sysdyn.clexchange.org MIT System Dynamics in Education Project (SDEP)<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20080509163801/http://sysdyn.clexchange.org/ |date=2008-05-09 }}</ref>  What makes using system dynamics different from other approaches to studying systems is the language used to describe [[feedback]] loops with [[Stock and flow|stocks and flows]].  These elements help describe how even seemingly simple systems display baffling [[nonlinearity]].
