Model

A model is a simplified representation or abstraction of a system, object, or concept, designed to enhance understanding or predict outcomes. Models can take various forms, including physical, mathematical, or computational, and are widely used in fields like science, engineering, economics, and social sciences.

For example, in science, a model may represent molecular structures, while in economics, it might illustrate market behaviors. Models help researchers test hypotheses, simulate scenarios, and visualize complex interactions. They are not perfect replicas; rather, they focus on key features that matter for analysis. The accuracy of a model depends on the quality of its assumptions and the data used. Ultimately, models serve as essential tools for exploration, communication, and decision-making across disciplines.
