As Information is defined a physical value, which completely characterizes an elementary object, during an interaction is exchanged and which describes the change of properties of the object after an interaction, [2].
Function of physics is a description of nature on the basis of physical laws. Function of a theory of physical information is to interpret, if possible, all physical phenomena of nature under application of the physical information and under a uniform law, [1].
The Project Physical Information is presenting a procedure, which is able to explain the phenomena in physics of elementary objects and related phenomena in cosmology under application of the physical information and under the conditions of the principle of Hamilton, that is on the basis of causality and locality .
The Physical Information Theory (PIT) is based on the classic physics and on quantum mechanics. Instead of applying, as in quantum mechanics, for the characterization of the elementary objects a wave function, in the PIT it is assumed that the whole Lagrange density together with the communication relations of quantum mechanics are characterizing the elementary object.
The products of the fields of the Lagrange density and the products of the commutators of communication relations are transferred with the help of the Fourier Transformation into correlations and under the conditions of the principle of Hamilton they united into correlation structures.
The theory of the physical information allows a new view on the physical foundations of nature.
