The Mathematics of Positive Feedback
Concomitant with the cybernetics revolution of the past half century has been the rapid development of mathematical modeling in the biological and ecological sciences, a methodology now firmly established. A model may be defined as an abstract description of the real world, a simple representation of more complex forms, processes, and functions of physical phenomena or ideas (Rubinstein, 1975). Models have aided in the understanding of ecological systems. When a model is put into explicit mathematical form, it can be analyzed to predict the effect on all parts of the system of external intervention on any single part.
