"nonlinear interactions almost always make the behavior of the aggregate more complicated than would be predicted by summing or averaging."

Today the network of relationships linking the human race to itself and to the rest of the biosphere is so complex that all aspects affect all others to an extraordinary degree. Someone should be studying the whole system, however crudely that has to be done, because no gluing together of partial studies of a complex nonlinear system can give a good idea of the behaviour of the whole.

paul ormerodIn fact, a very similar phrase was invented to account for the sudden transition of wood, metal, plastic and concrete into an explosive condition, which was "nonlinear, catastrophic structural exasperation," or to put it another wayas a junior cabinet minister did on television the following night in a phrase which was to haunt the rest of his careerthe checkin desk had just got "fundamentally fed up with being where it was."

The most essential example of the theory of selforganisation in chemistry is the theory of nonlinear, nonequilibrium thermodynamics of chemical reactions presented by Prigogine and his coworkers.
It is time to employ fractal geometry and its associated subjects of chaos and nonlinear dynamics to study systems engineering methodology (SEM). Systematic codification of the former is barely 15 years old, while codification of the latter began 45 years ago... Fractal geometry and chaos theory can convey a new level of understanding to systems engineering and make it more effective
