Introduction to Modelling
People create models to represent some real thing. When children model people, buildings, cars or other things,
they tend to use plastic, clay or other raw materials. Computers don’t.
They model things out of numbers and mathematical relationships. Because their models are not physical — something, for instance, that you can touch — scientists refer to computer models as being virtual representations.
Models ask "What if" questions.
