Idealization (physics)

from Wikipedia, the free encyclopedia

An idealization is a model of reality that does not take into account certain facts and disruptive influences. Depending on the problem, effects that are difficult to formulate are not included in the model under consideration, in order to be able to solve the problem at all (simplification) or to be able to present facts more concisely (concentration). The process of mapping reality in a model is known as modeling .

Every physical model is an idealization, since interactions with the environment are partially excluded or only come into play via effective values .

Consider the earth as an example of different hierarchies of idealization :

Other prominent models for idealizations are:
