3.4.1. The Logistic Model. In the previous section we discussed a model of population growth in which the growth rate is proportional to the size of the population. In the resulting model the population grows exponentially. In reality this model is unrealistic because envi-ronments impose limitations to population growth. A more accurate

The mathematical model used for shiphandling simulation consists of not one model, but a series of many models, each representing a particular piece of hardware or important physics. These models are interconnected inside the computer that runs the simulator to reflect the physical interactions among the elements they represent.
After developing a conceptual model of a physical system it is natural to develop a mathematical model that will allow one to estimate the quantitative behavior of the system. Quantitative results from mathematical models can easily be compared with observational data to identify a model's strengths and weaknesses.

mathematical models designed and applied, with the aid of computer sci-ences and devices, to the simulation of systems of real world. The term mathematical sciences refers to various aspects of mathematics, speciﬂcally analytic and computational methods, which both cooperate to the design of models and to the development of simulations.
Mathematical models of behavior that are developed through basic behavioral research can be used to predict or control behavior in applied settings. The models have been used in neuroscience and psychopharmacology to help researchers identify the functions of different brain structures and to assess the behavioral effects of different drugs.

Liquid–liquid phase separation (LLPS) is widely utilized by the cell to organize and regulate various biochemical processes. Although the LLPS of proteins is known to occur in a sequence-dependent manner, it is unclear how sequence properties dictate the nature of the phase transition and thereby influence condensed phase morphology.

Applied behavior analysis (ABA) has been referred to as "the science devoted to theunderstanding and improvement of human behavior" (Cooper, Heron, & Heward, 2007). Behavior is understood by observing the relationship of behavior to the environment, which incorporates rules governing learning and maintenance of behaviors.

So typically when we have a mathematical model of human or animal behavior, the model is not explaining "what it feels like" to produce the behavior; instead, like any other mathematical model of a phenomenon, it is saying, "the behavior can be explained as the outcome of a set of processes applied to particular types of representations."
