  2. Spacetime - Wikipedia

    en.wikipedia.org/wiki/Spacetime

    In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...

  3. Records management - Wikipedia

    en.wikipedia.org/wiki/Records_management

    The records continuum theory is an abstract conceptual model that helps to understand and explore recordkeeping activities in relation to multiple contexts over space and time. Records management practices and concepts

  4. Space–time tradeoff - Wikipedia

    en.wikipedia.org/wiki/Spacetime_tradeoff

    A spacetime trade-off, also known as time–memory trade-off or the algorithmic space-time continuum in computer science is a case where an algorithm or program trades increased space usage with decreased time. Here, space refers to the data storage consumed in performing a given task (RAM, HDD, etc.), and time refers to the time consumed in ...

  5. Continuum (measurement) - Wikipedia

    en.wikipedia.org/wiki/Continuum_(measurement)

    In physics, for example, the space-time continuum model describes space and time as part of the same continuum rather than as separate entities. A spectrum in physics, such as the electromagnetic spectrum, is often termed as either continuous (with energy at all wavelengths) or discrete (energy at only certain wavelengths).

  6. Time–space compression - Wikipedia

    en.wikipedia.org/wiki/Timespace_compression

    "Time-space compression", she argues, "needs differentiating socially": "how people are placed within 'time-space compression' are complicated and extremely varied". In effect, Massey is critical of the notion of "time-space compression" as it represents capital's attempts to erase the sense of the local and masks the dynamic social ways ...

    en.wikipedia.org/wiki/Continuum

    Space-time continuum, any mathematical model that combines space and time into a single continuum; Continuum theory of specific heats of solids, see Debye model; Triune continuum, trinity of continual representations in general system modeling defined in the theory of triune continuum, used in the triune continuum paradigm; Continuous spectrum ...

  8. Records continuum model - Wikipedia

    en.wikipedia.org/wiki/Records_Continuum_Model

    The records continuum model. The records continuum model (RCM) is an abstract conceptual model that helps to understand and explore recordkeeping activities. It was created in the 1990s by Monash University academic Frank Upward with input from colleagues Sue McKemmish and Livia Iacovino as a response to evolving discussions about the challenges of managing digital records and archives in the ...

  9. Time - Wikipedia

    en.wikipedia.org/wiki/Time

    Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. [1] [2] [3] It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the ...
