[1400–50; late Middle English < Latin < Greek; akin to chasm] cha·os (kā′ŏs′) Mathematics A system, such as the weather, that develops from a set of often simple initial conditions but behaves very differently if the initial conditions are changed even slightly. Chaotic systems often appear random and unpredictable, but in fact have regular patterns that are repeated at any scale of observation.

Chaos (kā`ōs), in Greek religion and mythology, vacant, unfathomable space. From it arose all things, earthly and divine. There are various legends explaining it. In one version, EurynomeEurynome
, in Greek mythology, daughter of Oceanus and Tethys and mother, by Zeus, of the Graces. In the mythology of the Pelasgians, an aboriginal non-Greek people living in Greece before the Mycenaean period, she rose alone out of chaos and separated the earth from the sky.

Eventually the word chaos came to mean a great confusion of matter out of which a supreme being created all life.Chaos System behavior that depends so sensitively on the system's precise initial conditions that it is, in effect, unpredictable and cannot be distinguished from a random process, even though it is deterministic in a mathematical sense. Throughout history, sequentially using magic, religion, and science, people have sought to perceive order and meaning in a seemingly chaotic and meaningless world. This quest for order reached its ultimate goal in the seventeenth century when newtonian dynamics provided an ordered, deterministic view of the entire universe epitomized in P. S. de Laplace's statement, “We ought then to regard the present state of the universe as the effect of its preceding state and as the cause of its succeeding state.” But if the determinism of Laplace and Newton is totally accepted, it is difficult to explain the unpredictability of a gambling game or, more generally, the unpredictably random behavior observed in many newtonian systems. Commonplace examples of such behavior include smoke that first rises in a smooth, streamlined column from a cigarette, only to abruptly burst into wildly erratic turbulent flow (see illustration); and the unpredictable phenomena of the weather. See Fluid flow, Turbulent flow  Transition from order to chaos (turbulence) in a rising column of cigarette smoke At a more technical level, flaws in the newtonian view had become apparent by about 1900. The problem is that many newtonian systems exhibit behavior which is so exquisitely sensitive to the precise initial state or to even the slightest outside perturbation that, humanly speaking, determinism becomes a physically meaningless though mathematically valid concept. But even more is true. Many deterministic newtonian-system orbits are so erratic that they cannot be distinguished from a random process even though they are strictly determinate, mathematically speaking. Indeed, in the totality of newtonian-system orbits, erratic unpredictable randomness is overwhelmingly the most common behavior. See Classical mechanics, Determinism One example of chaos is the evolution of life on Earth. Were this evolution deterministic, the governing laws of evolution would have had built into them anticipation of every natural crisis which has occurred over the centuries plus anticipation of every possible ecological niche throughout all time. Nature, however, economizes and uses the richness of opportunity available through chaos. Random mutations provide choices sufficient to meet almost any crisis, and natural selection chooses the proper one. Another example concerns the problem that the human body faces in defending against all possible invaders. Again, nature appears to choose chaos as the most economical solution. Loosely speaking, when a hostile bacterium or virus enters the body, defense strategies are generated at random until a feedback loop indicates that the correct strategy has been found. A great challenge is to mimic nature and to find new and useful ways to harness chaos. Another matter for consideration is the problem of predicting the weather or the world economy. Both these systems are chaotic and can be predicted more or less precisely only on a very short time scale. Nonetheless, by recognizing the chaotic nature of the weather and the economy, it may eventually be possible to accurately determine the probability distribution of allowed events in the future given the present. At that point it may be asserted with mathematical precision that, for example, there is a 90% chance of rain 2 months from today. Much work in chaos theory seeks to determine the relevant probability distributions for chaotic systems. Finally, many physical systems exhibit a transition from order to chaos, as exhibited in the illustration, and much work studies the various routes to chaos. Examples include fibrillation of the heart and attacks of epilepsy, manic-depression, and schizophrenia. Physiologists are striving to understand chaos in these systems sufficiently well that these human maladies can be eliminated. See Period doubling Reduced to basics, chaos and noise are essentially the same thing. Chaos is randomness in an isolated system; noise is randomness entering this previously isolated system from the outside. If the noise source is included to form a composite isolated system, there is again only chaos. chaos (kay -os) Broken terrain. The word is used in the approved name of such a surface feature on a planet or satellite.chaos[′kā‚äs] (mechanics) chaotic behavior chaos the disordered formless matter supposed to have existed before the ordered universe chaos (mathematics)A property of some non-linear dynamic systemswhich exhibit sensitive dependence on initial conditions.This means that there are initial states which evolve withinsome finite time to states whose separation in one or moredimensions of state space depends, in an average sense,exponentially on their initial separation.
Such systems may still be completely deterministic in thatany future state of the system depends only on the initialconditions and the equations describing the change of thesystem with time. It may, however, require arbitrarily highprecision to actually calculate a future state to within somefinite precision.
