They come to you as part of any education, as physical models in all shapes and sizes from dolls, miniaturized cars and air planes and globes, as static visual representations as maps or pictures, in more abstract arithmetic or algebraic form, or as verbal or mental models in nearly all we learn. In fact 'modelling' is so common that we cannot speak, think or observe without using and modifying 'models', or 'abstractions' from 'reality' (if there is such a thing as 'reality' at all). However, there are many different types of models and languages in which they can be expressed and there are different ways how to go about developing and improving models. </style></abstract></record></records></xml>
