And in the field of mathematical biology, Winfree used the geometric idea to study biological oscillations such as circadian rhythms and heart rhythms. By 1980 the widespread interest in chaos, fractals, oscillators and their applications had taken a firm root for this emerging field of dynamics. This resulted in the rapid growth of developing theories and other mathematical tools to deal with the systems. One of these would lead to the development of the control of chaos in the early 1990's. A small error in the former will produce an enormous error in the latter.
Prediction becomes impossible.
A nonlinear system is a system that is not in the first degree. In particular cases one inferred that chaos was an unwanted anarchic quality. In the past people have incorporated this idea of disorder into chaos. Dictionaries defined chaos as turmoil, turbulence, and primordial abyss. Biblical references to Tohu and Bohu had the same referential character of undesired randomness.
