This paper considers the application of Kutta-Joukowski law for description of a number of phenomenon inherent to biological cells in the framework of Rosen biological optimality theory. The applicability of this approach to model artificial cells is demonstrated and the possible application of similarity theory together with dimensional theory for this purpose is also outlined.

In this short note we consider the way in which a useful approximation of -shark tooth‖ stalactites morphology can be obtained with a very simple mathematical function. The approximation is not applicable for other stalactite morphologies, because this possibility can be used only in very special applications, where the solution (or approximation) process is complicated by the presence of some more patterning effects. We shall not consider this complicated question in this article. We only pay attention to the fact that some stalactite patterning mechanisms admit a simple geometrical interpretation in the frame of particle swarm optimization theory.
