Why is chaos theory important?
Every branch of pure mathematics has applications, usually to science or technology, which are important to society. In the case of dynamical systems theory, extensive and ongoing applications to all of the physical, biological, and social sciences have been fundamental to our evolving culure. The most frequent kind of application is to the technology of modeling complex natural systems. The importance of chaos theory has been in the context of this modeling aspect of applied dynamics. Because of the new wisdom of chaotic motions, many more complex systems now have useful models: the biosphere, the global economy, the human immune system, and so on. Different models for subsystems, created by scientists of disjoint specialities, may now be combined into a single complex supemodel, thanks to chaos theory. It provides a new technique for the unification of the sciences.
