Mentioning people, proper quoting, and linking to sources are the foundational features of this site. I am trying to be diligent with it, and to filter such information easier, I have assigned two labels (tags) to connection: citation and link. I also often provide the definitions I use to be more clear. I would like my site to stand out from the sea of misinformation and partial unorganized factual information. I want to make sense.

Therefore, I organize all external informational connections in two groups:

  1. Citation, mentioning:
    1. Names of people mentioned;
    2. Passages from publications, quotations.
  2. Link:
    1. Sources of information;
    2. Titles of publications containing the facts;
    3. Origination of definitions and standards.

When possible, I summarize my knowledge of the topic the way you see below. Natural languages and sub-cultures are somewhat messy, so by cultivating this habit in myself I make it easier for myself to navigate terminology, and the reader have more instant clarity.


References include information about external sources - links, citations, mentions, names, and titles - and point out relations between informational objects.


Definitions are statements of the meaning of a term:

  1. Intensional - give the sense of a term by naming properties that a thing must have in order to be part of the set.
    In logic and mathematics, an intensional definition gives the meaning of a term by specifying necessary and sufficient conditions for when the term should be used.
  2. Extensional - list the objects that a term describes).
    Extensional definitions are used when listing the members of a set tells the questioner enough about the nature of that set, or gives more applicable information than other types of definition.
  3. Ostensive - convey the meaning by pointing out examples of one or more members of a set, but not necessarily all.

A term may have many different senses and multiple meanings, and thus require multiple definitions. Definitions and axioms are the basis on which all of modern mathematics is constructed.


Standard is a criterion, an acknowledged measure of comparison for quantitative or qualitative value. Standards can be:

  • Objects that under specified conditions represents the unit.
  • Degrees or levels of requirement or excellence.
  • Sets of specifications that are adopted to allow compatibility.

Knowledge - useful information, facts, methods, tips, tutorials - presentations of concepts, abstract ideas, general notions, conceptions, abstractions, theories, hypotheses, and beliefs and convictions based on factual information and experience.
