Modelling and Simulation in Gerontechnology

Abstract

There are many ways to represent objects and processes in the world. We do it physically by painting or drawing pictures of people and nature, we do it in three dimensions with model railroads and dolls. A model might be a drawing, perhaps to scale, of a house with flat paper furniture that we move around to see where it looks nicest and functions best: this is much easier than moving the actual furniture. A model always is easier or better in some way than the real thing. It is lighter, or smaller, or simpler and cheaper to make, or can be tested and destroyed without negative consequences.
