  2. Unconventional computing - Wikipedia

    en.wikipedia.org/wiki/Unconventional_computing

    Unconventional computing (also known as alternative computing or nonstandard computation) is computing by any of a wide range of new or unusual methods.. The term unconventional computation was coined by Cristian S. Calude and John Casti and used at the First International Conference on Unconventional Models of Computation [1] in 1998.

  3. An Introduction to Non-Classical Logic - Wikipedia

    en.wikipedia.org/wiki/An_Introduction_to_Non...

    The first edition, published in 2001, was titled simply An Introduction to Non-Classical Logic. In 2008, Priest published a substantially expanded and revised second edition under the title An Introduction to Non-Classical Logic: From If to Is. [1] The second edition more than doubled the length of the original text, expanding from 242 to 613 ...

  4. Non-Euclidean geometry - Wikipedia

    en.wikipedia.org/wiki/Non-Euclidean_geometry

    In mathematics, non-Euclidean geometry consists of two geometries based on axioms closely related to those that specify Euclidean geometry. As Euclidean geometry lies at the intersection of metric geometry and affine geometry , non-Euclidean geometry arises by either replacing the parallel postulate with an alternative, or relaxing the metric ...

  5. Non-classical logic - Wikipedia

    en.wikipedia.org/wiki/Non-classical_logic

    Non-classical logics (and sometimes alternative logics or non-Aristotelian logics) are formal systems that differ in a significant way from standard logical systems such as propositional and predicate logic. There are several ways in which this is commonly the case, including by way of extensions, deviations, and variations.

  6. Curry–Howard correspondence - Wikipedia

    en.wikipedia.org/wiki/Curry–Howard_correspondence

    In programming language theory and proof theory, the Curry–Howard correspondence is the direct relationship between computer programs and mathematical proofs.It is also known as the Curry–Howard isomorphism or equivalence, or the proofs-as-programs and propositions-or formulae-as-types interpretation.

  7. Convention (norm) - Wikipedia

    en.wikipedia.org/wiki/Convention_(norm)

    A convention influences a set of agreed, stipulated, or generally accepted standards, social norms, or other criteria, often taking the form of a custom.. In physical sciences, numerical values (such as constants, quantities, or scales of measurement) are called conventional if they do not represent a measured property of nature, but originate in a convention, for example an average of many ...

    In model theory, a discipline within mathematical logic, a non-standard model is a model of a theory that is not isomorphic to the intended model (or standard model). [1]
