  2. Dimension - Wikipedia

    en.wikipedia.org/wiki/Dimension

    The inductive dimension of a topological space may refer to the small inductive dimension or the large inductive dimension, and is based on the analogy that, in the case of metric spaces, (n + 1)-dimensional balls have n-dimensional boundaries, permitting an inductive definition based on the dimension of the boundaries of open sets. Moreover ...

  3. Four-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Four-dimensional_space

    The idea of adding a fourth dimension appears in Jean le Rond d'Alembert's "Dimensions", published in 1754, [1] but the mathematics of more than three dimensions only emerged in the 19th century. The general concept of Euclidean space with any number of dimensions was fully developed by the Swiss mathematician Ludwig Schläfli before 1853.

  4. Multiple time dimensions - Wikipedia

    en.wikipedia.org/wiki/Multiple_time_dimensions

    Multiple time dimensions appear to allow the breaking or re-ordering of cause-and-effect in the flow of any one dimension of time. This and conceptual difficulties with multiple physical time dimensions have been raised in modern analytic philosophy. [9]

  5. Meaning of life - Wikipedia

    en.wikipedia.org/wiki/Meaning_of_life

    The first English use of the expression "meaning of life" appears in Thomas Carlyle's Sartor Resartus (1833–1834), book II chapter IX, "The Everlasting Yea". [1]Our Life is compassed round with Necessity; yet is the meaning of Life itself no other than Freedom, than Voluntary Force: thus have we a warfare; in the beginning, especially, a hard-fought battle.

  6. Five-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Five-dimensional_space

    A five-dimensional space is a space with five dimensions. In mathematics, a sequence of N numbers can represent a location in an N-dimensional space. If interpreted physically, that is one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics. [1]

  7. Hofstede's cultural dimensions theory - Wikipedia

    en.wikipedia.org/wiki/Hofstede's_cultural...

    Indulgence vs. restraint (IND): This dimension refers to the degree of freedom that societal norms give to citizens in fulfilling their human desires. Indulgence is defined as "a society that allows relatively free gratification of basic and natural human desires related to enjoying life and having fun".

  8. String theory - Wikipedia

    en.wikipedia.org/wiki/String_theory

    In everyday life, there are three familiar dimensions (3D) of space: height, width and length. Einstein's general theory of relativity treats time as a dimension on par with the three spatial dimensions; in general relativity, space and time are not modeled as separate entities but are instead unified to a four-dimensional (4D) spacetime. In ...
