Summary/Abstract: Based upon the example of geometrical optics and geometrical optics of electrons, as well as the theory of the electric field and the theory of the flow of the perfect liquid in two dimensions, the analogy of the laws of physics have been discussed. In the awareness of physicists, the analogy is a syntactical identity, of the physically interpreted mathematical formulas, describing the laws of physics. In the paper, it has been presented some relevant laws of the two pairs of the theories being compared. For the three cases, it has been provided the appropriate photographs presenting the results of the empirical tests of some of the relevant laws.
