Biophysics represents a science on fundamental laws underlying the structure, functioning, and development of living systems. Along with experimental methods, it actively uses mathematical models for describing the processes in living systems of various organization level, starting with biomacromolecules and then at the cellular and subcellular level, at the level of organs, organisms, populations and communities, biogeocenoses, and finally, at the level of the biosphere as a whole . The mathematization degree in this or another field of biophysics depends on the level of experimental cognition of the objects and on the facilities of mathematical formalization of the processes under examination.
The importance of key figures is of great importance here. They are a powerful tool in experimental research on a multitude of physical phenomena. In practice, the execution of the research often proves to be extra complicated because the large number of influencing quantities requires an enormous amount of measurements before a proper insight into the mutual dependence of the quantities can be obtained. Dimensional analysis can often reduce the number of quantities so drastically that only 2 or 3 combined quantities remain, so that the entire phenomenon can be represented in just one diagram.
