PHYSICAL THEORY: KEY TERMS AND ITS MATHEMATICAL COMPONENT

Abstract

Actual scientific researches and issues analysis. The movement from classical physics to modern physics occurred as a result of the emergence of a number of paradoxes in classical theory. This feature is characteristic to some extent of the electromagnetic theory of Maxwell, Einstein's theory of relativity, etc. The research objective . We will try to consider the key terms of physical theory and show the role of the mathematical component in its creation. The statement of basic materials. The article deals with some modern problems of the methodology and foundations of physics, in particular: whether mathematical formalisms contain interpretations of themselves or whether they need to be supplemented by interpretive predictions, and if so, how these predictions are formulated; what physical theories describe: physical systems or laboratory operations, either one or another, or neither of them; how the basic concepts of theory should be introduced, by reference to measuring operations, or by means of clear definitions, or axiomatically; how physical theories relate to each other; how theory relates to experiment: directly or with the help of additional theories.
