It is common to use idealized models in physics to simplify things.

Any macroscopic system is always much more complicated than any idealized mathematical model describing it.

The answer to this question depends on how much the realities of the infection process deviate from our idealized model.

A point charge is an idealized model of a particle which has an electric charge.

This process is fitting an idealized model to real world data, and seeing what parameters in the model make it fit reality best.

In the idealized model, we assume the atmosphere is completely transparent to sunlight.

Perfect fluids are idealized models in which these possibilities are neglected.

In statistics, reification is the use of an idealized model of a statistical process.

Such idealized models can capture many of the statistical regularities of systems.

These were societies set up according to an idealized theocratic model.
