found a list of system dynamics courses of off www.systemdynamics.org. A lot of them use MIT Prof John Sterman's book Business Dynamics: Systems Thinking and Modeling for a Complex World
I think I'll check it out. Right now I'm reading World Dynamics by Jay Forrester. I need to get a CD with the World3 model on it, and also figure out how to do the modeling. I did a little bit, but I don't really understand how to use it.
I also want to check out Beyond Growth, by economist Herman Daly.
