Physical basis of measurements and standards

Abstract

The manual presents elements of the theory of similarity and dimensions, presents concepts of classical measurement systems, elements of the modern physical picture of the world, stability of fundamental physical constants. The Heisenberg uncertainty relation, the principle of complementarity, the principles of creating a modern reference base based on the stability of micro-world objects, the essence of physical phenomena and effects, and the physical foundations of measuring con-verters in engineering are con-sidered.
