Parker is careful to point out that not every narrative benefits from the chaos theory, and the texts to which she applies the analogy in this study are carefully chosen for the ways in which they particularly exemplify aspects of a dynamical systems theory.
Gleick [3] in his popular book on chaos, gives the views of several researchers: the complicated, aperiodic attracting orbits of certain dynamical systems, apparently random recurrent behavior in a simple deterministic system, the irregular, unpredictable behavior of deterministic nonlinear dynamical systems.
We thus illustrate precisely how physical laws in the classical regime of dynamical systems fail to exhibit predictive power.

In contrast, each machine process is correct as a dynamical system in its own right [6].
It is also important to point out that mathematically, it is in principle decidable whether a dynamical system is stable or not, although in many cases it is a hard task in practice.
