From Quantum Mechanics to Lagrangian Densities Just as there is no “derivation” of quantum mechanics q from classical mechanics, there is no derivation of relativistic field theory from quantum mechanics. The “ oute” om ne e ther ased n hysically route from one to the other is based on physically reasonable postulates and the imposition of Lorentz invariance and relativistic kinematics .T h e final “theory” is a model whose survival depends absolutely on its success in producing “numbers” which agree with experiment.
