Model

Model may refer to more than one thing :

  • In mathematics, particularly in set theory, a model is some concrete realization of a set of axioms (in a sense this is the opposite of the previous definition). See model theory.
  • A scale model is a replica or prototype of an object built either for research or as a hobby, usually built smaller than the existing or intended thing, though can equally be built larger to illustrate something that would otherwise be hard to see. Plastic models are very common for hobbyists.
