esult), and for this purpose the system's actions should be the same (the principle of a constancy of correspondence of actual actions of the system to the due ones). If the result fails to be constant it cannot be appropriate and equal to the preset result (the principle of consistency/permanency of the result of action). The conservation law proceeds/results/from the principle of consistency/permanency of action. Let us call the permanency of reaction "purposefulness", as maintaining the similarity (permanency/consistency) of reaction is the goal of a system. Hence, the law of conservation is determined by the goal/purpose. The things conserved would be those only, which correspond to the achievement of the system's goal. This includes both actions per se and the sequence of actions and elements needed to perform these actions, and the energy spent for the performance of these actions, because the system would seek to maintain its movement towards the goal and this movement will be purposeful. Therefore, the purpose determines the conservation law and the law of cause-and-effect limitations (see below), rather than other way round. The conservation law is one of the organic, if not the most fundamental, laws of our universe. One of particular consequences of the conservation law is that the substance never emerges from nothing and does not transform into nothing (the law of conservation of matter). It always exists. It might have been non-existent before origination of the World, if there was origination of the World per se, and it might not be existent after its end, if it is to end, but in our World it does neither emerge, nor disappear. A matter is substance and energy. The substance (deriving from the/Rus/word "thing", "Object") may exist in various combinations of its forms (liquid, solid, gaseous and other, as well as various bodies), including the living forms. But matter is always some kind of objects, from elementary particles to galaxies, including living objects.Substance consists of elements. Some forms of substances may turn into others (chemical, nuclear and other structural transformations) at the expense of regrouping of elements by change of ties between them. Physical form of the conservation law is represented by Einstein's formula. A substance may turn into energy and other way round. Energy (from Greek "energeia" - action, activity) is the general quantitative measure of movement and interaction of all kinds of matter. Energy in nature does not arise from anything and does not disappear; it only can change its one form into another. The concept of energy brings all natural phenomena together. Interaction between the systems or between the elements of systems is in effect the link between them. From the standpoint of system, energy is the measure (quantity) of interaction between the elements of the system or between the systems which needs to be accomplished for the establishment of link be...
