The advance of physics is the development of research methodology which is based on the perception and direct experimental data. Today physics is lost in mathematical models which are proven by some indirect experimental data. The school example is the existence of the Higgs mechanism, namely, Higgs boson does not prove the existence of the Higgs field. In this book, a new vision of physics based on bijective research methodology is proposed where each physical equation satisfies the bijective function i.e. each element of an equation corresponds to a particular element in the real world. Likewise, every equation and physical model has bijective correspondence with the real world. Bijective analysis realizes Einstein's vision of completeness of a physical theory. According to Einstein, a theory can be considered complete if every element of the physical theory has a counterpart in the physical reality.
