Chaos may be used as a term for extremely high and barely detectable forms of order in some phenomena, that formerly were thought to be characterized by randomness or chance. Stated negatively this order arises from a constraint in randomness that is termed by some an 'attractor' or 'strange attractor', and by others 'logos', or mathematical limit.
Non-random chaos may be produced by the introduction, into a stable system, of wave frequencies (such as harmonics). In applications of this theory, to weather forecasting for example, or to human heart fibrillation study, the efforts are to understand the logos or limit in both order and chaos. In one sense it is the 'load' of frequencies that a homeostatic system can bear.
