Idealization: idealization is a simplification of theories for the purpose of generalization. A) Before starting an investigation in physics, e.g. the assumption of a mass point, i.e. a practical impossibility, which, however, simplifies the calculation and delivers correct results. B) Subsequently, for example, the smoothing of the course of a curve of measured values. See also Theories, measurements.

Approach/Cartwright: deputy.
I 107
They lead away from the theory - but can lead to the truth.
I 111
Idealization/Science/Cartwright: does not only omit, but introduces something that is not prescribed by the fundamental laws. - Approach: We cannot make corrections at the beginning. - We cannot correct backwards and thus assume to come out at a fundamental law -> crossover effects.
I 119
It may be that what is the correct approach is not decided by the facts. ((s)> Non-factualism). - I.e. two approaches (with different results) can be justified by the same facts - the same approach, if applied in different places, can have different results: E.g. Lamb shift: excited atom or in the base state - not a fact prescribes which is to be assumed.
I 121
Accuracy is only apparent if the initial problem is not given exactly.
I 150
Idealization/Distortion/Science/Physics/Cartwright: Example a) interested in atoms: Then distortion in the description of the field (E.g. infinite number of degrees of freedom) - b) if field is examined: then infinite degrees of freedom stored in the walls of the laser cavity, etc. - realistic: is an approach that uses more bridge principles.

Approximation/Cartwright: Problem: approximation should lead away from confusing details - but the number of possible approximations itself is confusing - most approximate equations are themselves already simplifications of equations that you could not solve.
