It was accompanied by a long form music video release of the same name, although it did not contain all of the songs from the album. It is a concept album presented as a motivational business document.
Reverse mathematics is a program in mathematical logic that seeks to determine which axioms are required to prove theorems of mathematics. Its defining method can briefly be described as "going backwards from the theorems to the axioms ", in contrast to the ordinary mathematical practice of deriving theorems from axioms.
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [ 1 ] and the LaTeX symbol.
Logicians define conversion per accidens to be the process of producing this weaker statement. Inference from a statement to its converse per accidens is generally valid. However, as with syllogisms , this switch from the universal to the particular causes problems with empty categories: "All unicorns are mammals" is often taken as true, while ...
Semantic completeness is the converse of soundness for formal systems. A formal system is complete with respect to tautologousness or "semantically complete" when all its tautologies are theorems, whereas a formal system is "sound" when all theorems are tautologies (that is, they are semantically valid formulas: formulas that are true under every interpretation of the language of the system ...
Backward chaining (or backward reasoning) is an inference method described colloquially as working backward from the goal. It is used in automated theorem provers , inference engines , proof assistants , and other artificial intelligence applications.
Completion (algebra), at an ideal; Completeness (cryptography) Completeness (statistics), a statistic that does not allow an unbiased estimator of zero; Complete graph, an undirected graph in which every pair of vertices has exactly one edge connecting them
