What do Zadeh's fuzziness and Weaver's complexity have in common in cybernetics?

Till now, all the research and modeling in biology and medicine stayed within various stochastic methods and theories. However, N.A. Bernstein, the famous physiologist and expert in biomechanics, W. Weaver, the founder of information theory, and L.A. Zadeh, the mathematician and the founder of the Fuzziness concept proposed a different approach to biosystem definition and modeling in the middle of the 20th century. 50 years later, the Eskov–Zinchenko effect in biomechanics was discovered, and the real era of making a new theory and new science for describing complex medical systems began. This theory is based on the proven statistical instability of any biosystem property samples. At the same time, an analog of the Heisenberg uncertainty principle in biomedicine was created. All this made it possible to propose a new interpretation of the homeostasis concept in biomedicine and a special theory and models in medical and biological cybernetics.
