Every object and every idea can be used as a model in an application scenario, if it becomes useful in the scenario as an instrument in a function. Through this use and function, an object or idea becomes a model, at least for a certain or long time for the respective model user in its context and environment.

Models are works of art of thinking. They come in the most diverse forms: small ingenious, ever-present, medium-sized or even elaborate ones of imposing size and full of hidden secrets. Quiet ones, animated by a flash of inspiration. Groundbreaking and revolutionary. Methodically overwhelmingly sophisticated ones that stand on the shoulders of giants. Simple ones that are so well put together that everyone likes them and understands them and cannot refuse them.

Modelology is a novel discipline that handles model development and usage in a systematic and well-founded way. We introduce the central kernels of this new science, art, and culture.
