These observations allow one to formalize the definition of reflection: a reflection is an involutive isometry of an Euclidean space whose set of fixed points is an affine subspace of codimension 1.
In effect, every one of these functions here can be thought of as formalizingand encapsulating, in computational terms, some facet of the intellectual achievements of our civilization.
These production rules, and the selection algorithm, combine to form what’s called a Domain Model, which is a formal representation of the knowledge, procedures and skills of a particular discipline - like algebra.
The goal is to formalize what we know about the world in computational terms, to have computational ways to represent cities and chemicals and moviesand humor and formulas and our knowledge about them.
I think that it operates as a psychological and psychic framework that frees me from normal verbal reference, letting me express and communicate inner feelings and data that lie just beneath formalized word patterns.
