. Nor should economists urgently develop their own unique mathematical calculations to describe economic phenomena, independent of physics. After all, why re-invent the wheel? All that is needed is to make use of some of the most salient and staggering achievements of humanity at the present time by borrowing from theoretical physics. These can be put to use for the good of the development of economic science and the global economy. This book is one of the many steps in the right direction along the proper road. Hopefully I am not wrong, although there is always that chance. There is no doubt that it will be a long road to this accomplishment, and most certainly not a fast one.
I am well aware that the very idea of using methods of theoretical physics, especially quantum mechanics, for describing economic phenomena must cause a healthy dose of skepticism from the physicists. Therefore, I emphasize that the discussion deals with the fact that only the mathematic framework of theoretical models of the respective physical systems are transferred to the physical economic models.
I incorporate into economics only the formal structural aspects of physical theories. First of all are the equations of motion for the many-particle systems, which just by themselves must not be too rigidly attached to real physical microscopic objects. Equations – they are just equations and nothing more, and if they are a beneficial descriptive tool in another science, why not make use of them? I repeat that this is just a useful mathematical object which can and should be used as a theoretical tool where it can provide benefit. For instance, in quantum mechanics wave functions and the Schrödinger equations have been successfully used for the incorporation of the uncertainty and probability principle into physics. Why, then, can we not then apply the same mathematical apparatus to the analogous uncertainty and probability principle in economic theory for purposes of mathematical description?
It is obvious that this is only an initial approximation to reality. But we are talking about modeling economic systems, and models are only models, giving only an approximate shape to the object being modeled. My physical models of economic systems also do not pretend that they are complete and precise; they can give only the approximate patterns of our market economic world, only the specific stage in our understanding of the real economic world transposed into the language of mathematics. A physical economic model is nothing other than a certain ideal, imagined construction, aimed at explaining one or more aspects of the studied phenomenon. The question is not whether it is correct or not, but whether it is useful in helping to reach a true understanding of the real economic world. Nothing more. I think that by means of this approach, some insight into the important market economy phenomena has been gained in this study.
