What is complexity? In short, I’m refering to complexity science, which is the study of complex systems. It’s a fairly large and interesting field that I’ve been sucked into by my Sociology professor (Thanks, Brian!). Interest in this field plus a high level of computer geekyness will land you smack in the middle of computational sociology – which is where I’m at now. http://www.personal.kent.edu/~mdball has some of the computer models that I’ve worked on. Some other great resources for this field are the SACS website and the SACS Blog.
For a more comprehensive definition of complexity and computational sociology, give my Sociology of Complexity page a read.
