Models are simplified representations of reality. We use models in many different ways, for many different purposes: physical models are used to study urban planning, vehicle impacts, new inventions, and molecular structures; rats are used as model organisms to test new pharmaceuticals for side effects; conceptual models are used to simplify and understand concepts, ideas, and relationships; mathematical models are used to understand, quantify, and predict the behaviour of the natural world. All models are intended to capture some key feature of reality (shape, behaviour, relationships, etc.); the specific focus of a model will depend on the purpose for which the model is intended to be used.
