Read the following text and answer the following questions: // I do not know too much about the chaos theory. I have heard is a theory that pose that every dynamic system tends to be unruly, disordered and unpredictable. I think this text will explain the chaos theory, and its consequences- if they are any. Probably in this tex will be also commented the first questions and ideas that lead to formulate this theory. I think I will find words such as “disorder”, “systems”, “science”, “unpredictable”, “aplication of the theory”.

[] __ Chaos Theory __ __, __ __ theory __ __ describing the complex and unpredictable motion or dynamics of systems that are sensitive to their initial conditions __. __ Chaotic systems __ (// systems is also the general class//) __ 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 (//systems)//. __ 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.

I just found two of them, science and systems. I could not find the others, even thought, I find some phrases with similiar singnificance. I did not find “application of th theory” but it says “The field of chaos is evolving rapidly from a theoretical to an applied science”, so is seems to be a practic application of this theory. I did not find “unpredictable” but is says “The unpredictability of chaotic systems arises due to their sensitivity to their initial conditions”, so, chaotic systems are unpredictable.

__Them__ refers to the scientists that could not appreciated Poincaré’s discovery. __That__ refers to the structure on an specific chaotic model. Chaos Theory is more interesting than I thought. I understood systems just tend to be disordered, but this teory pose much more that that. It bassically says that, for some systems called chaotics, small differences in the initial conditions of the motion of those systems lead to final results totally different than expected, becoming those unpredictable, depending on the sensibility of the systems to the conditions. Even if it sounds too complicated, solar systems seems to be a chaotic system, and this theory could be also applied to economics systems. Actually, most of the information in the tex was new for me.

 * 6. What new aspects did you discover about the chaos theory? **

Yes, it is related to real life aspects, because, as it said in the text, this theory can be applied to economic system, solar system, electric circuits, and it can also be applied to organic and biological systems, because electrical brain activity and circadian rihythm are chaotic systems.
 * 7. Is the chaos theory related to real life aspects? **** Explain. **
