ABSTRACT
A literature overview from 1953 until the first workable model description published in 2014 by Goede et al. showed the deficiency and limitations of dynamical modeling of these systems. The complexity of biological systems is the result of millions of years of evolutionary development. Keeping this notion in mind, authors can understand that most biological manifestations cannot simply be reduced to their library of understandings. However, they can try to use their imagination and common sense and try to find comparable and recognizable mechanical or electrical functions to see what really happens when they investigate a biological entity. It is not the internal organization, but moreover the final external manifestation of what they encounter and what they can measure in the human physiology as the final result. Because the dynamics of a process makes it practically impossible to come to a usable kind of model, observation and measurement of an equilibrium opens the way to discover the underlying dynamic behavior.
