The world of science dazzles with terms which sometimes begin to use also in everyday life. However using any given word, people not always correctly understand its value. So it happened also to the concept "verification".
Verification is a modeling of evident model for any scientific theory. For example, points, direct and other figures – ideal geometrical objects - correspond to their sensual images. Strictly speaking, verification is a proof, confirmation. But confirmation is verification only when direct proof of theoretical provisions of science is proved by return to the evident level of set of the acquired knowledge by practical consideration. That is when the nature of abstractions which is ideal is ignored, and they become identical with an observed object. This term occurred at the beginning of the twentieth century from the Latin words verus – true and facio – I do. The idea of verification grew ripe gradually when logical deduction received strengthening in development of scientific concepts. There was it when there was obvious an awareness of possible discrepancy between intuitive thinking and abstract thinking which is connected with presentation. Mainly this understanding comprehended the exact sciences – mathematics and theoretical physics. All this was expressed in need of justification of communication between reality and abstraction. This need was especially brightly defined by I. Kant in the expression of positions of empirical philosophy in the form of a practical exception of any abstraction. Kant claimed that there is a need to make evident any abstract concept, namely it is necessary to show the object corresponding to an abstract concept of contemplation. Without this concept an object would be senseless. This requirement received the status of the methodological principle of a possibility of skilled check of verification in neopositivism philosophy. In some way it is identical to the requirement of practical applicability of abstractions. It was expressed in a complete elimination of abstractions and change by their concrete, certain objects. However, as we know, not any applied abstraction can be excluded in the evident way, that is to verify. Not each reality which reflection is abstraction is evident. The criterion of verification in that case is not criterion of practice. Do not confuse a concept of verification with a concept of validation, verification is always based on comparison of real prototypes with the template created on a design phase.
