In the section headed «The
chaotic», we
see that the intuition that «deterministic rules of
behaviour give rise to completely predictable events» is violated everywhere, from weather systems to ecosystems.
«Watching nature red in tooth and claw is certainly one way to
see counterintuitive,
chaotic behaviour rear its ugly head,» writes Casti.
«A dynamical system such as the climate system, governed by nonlinear deterministic equations (
see Nonlinearity), may exhibit erratic or
chaotic behaviour in the sense that very small changes in the initial state of the system in time lead to large and apparently unpredictable changes in its temporal evolution.
Linear feed - back systems are already completely capable of
chaotic behaviour, no non-linearity required;
see coupled pendulums; and the SB Law feedback (grey body IR emission) is on the other hand highly non-linear all on its own...
Rather than attack Tom you should
see him as an example of climate scientists of all persuasions who are trying to analyse the
behaviour of complex
chaotic systems by the application of simplistic relationships studied in a laboratory.
If you followed an individual molecule you would
see an apparently
chaotic and random
behaviour in which it keeps jumping up and down among its quantum states.
I have just run a simple experiment to
see whether I can predict the average
behaviour of one of the simplest parametric
chaotic systems - the logistic map: def trial (s, k): x = s # starting point for i in range (10): x = k * (1 - x) * x print x for i in range (90): x = k * (1 - x) * x print x This map takes x to k (1 - x) x.
