Space consisting of a consistency of BP


Space consisting of the consistency of BP and is me,

The universal forms of existence of matterP. and V. do not exist outside of matter and independently of it.

  Spatial characteristics are positions relative to other bodies (coordinates of bodies), distances between them, angles between different spatial directions (individual objects are characterized by length and shape, which are determined by the distances between parts of the object and their orientation). Temporal characteristics - "moments" in which the phenomena occur, the duration (duration) of the processes. The relationship between these spatial and temporal quantities is called a metric. There are also topological characteristics of P. and V. - "contact" of various objects, the number of directions. They deal with purely spatial relations only in the case when it is possible to abstract from the properties and motion of bodies and their parts: with purely temporal ones - in the case when it is possible to abstract from the variety of coexisting objects.

  However, in reality, spatial and temporal relationships are related to each other. Their immediate unity appears in the movement of matter; the simplest form of movement - movement - is characterized by values ​​that represent various relations between P. and V. (speed, acceleration) and are studied by kinematicsModern physics has discovered a deeper unity between P. and V. (see Relativity theory ), which is expressed in a joint regular change in the Spatio-temporal characteristics of systems depending on the movement of the latter, as well as in the dependence of these characteristics on the concentration of masses in the environment.

  To measure spatial and temporal values, reference frames are used.

  With the deepening of knowledge about matter and motion, scientific ideas about P. and V. deepen and change. Therefore, to understand the physical meaning and significance of the newly discovered laws of P. and V. it is possible only by establishing their connections with the general laws of interaction and movement of matter.

  P. and century concepts. are a necessary component of the picture of the world as a whole, therefore they are included in the subject of philosophy. The doctrine of P. and V. deepens and develops along with the development of natural science and, above all, physicsOf the rest of the natural sciences, a significant role in the progress of the theory of P. and V. played astronomy and especially cosmology.

  Development of physics, geometry and astronomy in the 20th century. confirmed the correctness of the provisions of dialectical materialism about P. and V. In turn, the dialectical-materialist concept of P. and V. allows one to give a correct interpretation of the modern physical theory of P. and V., to reveal the unsatisfactory nature of both its subjectivist understanding and attempts to "develop" it, tearing P. and V. from matter.

  Spatio-temporal relations are subject not only to general laws but also to specific ones characteristic of objects of a particular class since these relations are determined by the structure of a material object and its internal interactions. Therefore, such characteristics as the size of an object and its shape, lifetime, rhythms of processes, types of symmetry, are essential parameters of an object of this type, which also depend on the conditions in which it exists. Spatial and temporal relations are especially specific in such complex developing objects as an organism or a society. In this sense, we can talk about individual P. and V. such objects (for example, about biological or social time).
