Let's take into account the functional structure of any cyber system. Hierarchical (bonded) scheme. Due to the self-regulation capacity it possesses, a real cybernetic system is not left "overwhelmed" of the environment (at least for a while), opting into a disorganizing action, the trend of entropy growth. Entropy is considered zero in the "total order" situations and will reach its maximum level if a "total disorder" will be reached. It is clear that both are "ideal" situations, reality, perpetually. Between the two extremes. Maintaining the level of organization achieved (opposing merge with the environment, the disappearance of their own qualitative determination - which would mean elevation of entropy), cyber systems are continuously adapting to the modifications of the environment through a process of maintaining the "homeostase" (the term we are familiar; Cybernetics took it, generalizing it from biology, more precisely in physiology).
Antien-tropic action, with the ordering of the environment and home-static action, achieving a dynamic, oscillatory, adaptive balance, are facilitated, determined by the existence of information, the possibility of receiving, processing and using them. So we are generally talking about the non-vertropic aspect of information. Another outstrip: When we study a cybernetic system, it is required to create the characteristics of its current behavior, the evolutionary trends, to sketch, with the maximum possible precision, its behavior. We are therefore interested in all that information that can help us distinguish the past, present and future of the system. It would be one of the arguments for which we have interlected from time to time the past of the human brain in "his current story41; and we will not have to omit, he always looked at him in the perspective. The secrets of the" Black Cut " "The black box" represents all those processes, phenomena, objects of our knowledge, which we can describe and modify the "inputs", "exits" without knowing them "interiors". Scheme (ideal!)
Of any communication process. A "black box14 is a" box "in which we do not know, in fact, what is happening. What we can find out at some point (if we want), is only what comes into the" box "and what comes out of it. We can cause some answers by noscind as "the box" react in similar circumstances, but we can not explain, step by step, phenomena . The brain, after cyberneticians, is such a "un-rra box". But when we consider The "black box" of the Cyber-Neticians are not going to ask one of what it is in it.
The notion especially uses it to establish, explicitly, those correlations, especially important sometimes between "inputs" and "outputs". Certainly intended for the study of complex dynamic systems, the method called "black box" has proven to have a meritorious contribution to the elaboration of forecasts on the evolution of a given system. They will intervene in making such operations our knowledge of mathematics and logic in the chapter "Functions". For hypercomplex dynamic systems such as the human brain or human society, the study of the state of each element or each link that is established between the elements is basically impossible. That is why it is used this careful selection of "significant" entries, their reporting to "outputs" with detachment of usable conclusions in the complex process of knowledge. Of course, whenever the effectiveness of cyber methodology is analyzed, and to what extent the "black box" has become the "white box". But the complete white box does not exist (always inside it is a "black box" of the upper level) as the truths that man discovers is always approaching the absolute truth,.
But they will never exhaust it. The secrets of "a" black box, "once loose, will bring in other" black boxes ". We will be able to download in these conditions in the" Negagra41 box that the brain is. Metabolism "Information?
