=Chaos Theory=  __ Chaos Theory, theory describing the complex and unpredictable motion or dynamics of systems that are sensitive to their initial conditions __. __ Chaotic systems are mathematically deterministic — that is, they follow precise laws, but their irregular behavior can appear to be random to the casual observer __. Chaotic behavior is common in systems as varied as [|electric circuits], [|measles] outbreaks, [|lasers], clashing [|gears], [|heart] rhythms, electrical [|brain] activity, circadian rhythms, fluids, animal populations, and [|chemical reactions]. It is suspected that even economic systems, such as the [|stock exchange], may be chaotic. The field of chaos is evolving rapidly from a theoretical to an applied science.  The dynamic nature of the universe has led to a great deal of scientific research dedicated to analyzing change. Until recently, it was believed that if the dynamics of a system behaved unpredictably, it was due to random external influences. Therefore, scientists concluded that if random influences could be eliminated, then the behavior of all such deterministic systems could be predicted indefinitely. It is now known that many systems can exhibit long-term unpredictability even in the absence of random influences. Such systems are called chaotic. Even very simple systems, such as a [|pendulum], exhibit chaos.  The unpredictability of chaotic systems arises due to their sensitivity to their initial conditions, such as their initial position and velocity. Two identical chaotic systems set in motion with slightly different initial conditions can quickly exhibit motions that are quite different. French mathematician [|Henri Poincaré] concluded that he could not prove the [|solar system] to be completely predictable. He was the first to state the defining feature of what later became known as chaos: “It may happen that small differences in the initial conditions produce very great ones in the final phenomena. A small error in the former will produce an enormous error in the latter. Prediction becomes impossible.…”  The ramifications of Poincaré's discovery were not fully appreciated by most scientists until computers allowed them to easily model and visualize chaotic systems. Before then, however, pioneering scientists and engineers at the [|National Aeronautics and Space Administration] used Poincaré's work to send people and satellites into orbit. Edward Lorenz, an American meteorologist, discovered in the early 1960s that a simplified computer model of the weather demonstrated extreme sensitivity to the initial measured state of the weather (//see// [|Meteorology]). He demonstrated visually that there was structure in his chaotic weather model that, when plotted in three dimensions, fell onto a butterfly-shaped [|fractal] set of points of a type now known as a strange attractor. Lorenz rediscovered chaos and proved that long-range forecasting of the weather was impossible. By the early 1980s, experiments regularly showed that many physical and biological systems behave chaotically. One of the first such systems to be discovered was the dripping water faucet. Under certain conditions, the timing between water drops from a leaking faucet demonstrates chaotic behavior, making the long-term prediction of the timing of drops impossible.  According to recent evidence, Poincaré's observations concerning the unpredictability of the solar system appear to be correct. Observations and computer simulations of the irregular tumbling motion of Hyperion, a potato-shaped moon of [|Saturn], have provided the first conclusive proof that objects in the solar system can behave chaotically. Recent computer simulations have also shown that the orbit of [|Pluto], the outermost planet of the solar system, is chaotic.  Scientists are currently developing applications that use chaos. New chaos-aware control techniques are being used to stabilize lasers, manipulate chemical reactions, encode information, and change chaotic heart rhythms into healthy, regular heart rhythms.
