  2. Time–space compression - Wikipedia

    en.wikipedia.org/wiki/Timespace_compression

    Timespace compression (also known as spacetime compression and timespace distanciation) is an idea referring to the altering of the qualities of spacetime and the relationship between space and time that is a consequence of the expansion of capital.

  3. Friction of distance - Wikipedia

    en.wikipedia.org/wiki/Friction_of_distance

    Friction of distance is a core principle of geography that states that movement incurs some form of cost, in the form of physical effort, energy, time, and/or the expenditure of other resources, and that these costs are proportional to the distance traveled.

  4. Tobler's first law of geography - Wikipedia

    en.wikipedia.org/wiki/Tobler's_first_law_of...

    The First Law of Geography, according to Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." [1] This first law is the foundation of the fundamental concepts of spatial dependence and spatial autocorrelation and is utilized specifically for the inverse distance weighting method for ...

  5. Time geography - Wikipedia

    en.wikipedia.org/wiki/Time_geography

    Time geography or time-space geography is an evolving transdisciplinary perspective on spatial and temporal processes and events such as social interaction, ecological interaction, social and environmental change, and biographies of individuals. [1] Time geography "is not a subject area per se", [2] but rather an integrative ontological ...

  6. Spacetime - Wikipedia

    en.wikipedia.org/wiki/Spacetime

    In physics, spacetime 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 occur.

  7. Spacetime diagram - Wikipedia

    en.wikipedia.org/wiki/Spacetime_diagram

    A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity. Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations. The history of an object's location through time traces out a line or ...

  8. Map projection - Wikipedia

    en.wikipedia.org/wiki/Map_projection

    Map projection. A medieval depiction of the Ecumene (1482, Johannes Schnitzer, engraver), constructed after the coordinates in Ptolemy's Geography and using his second map projection. In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane.

  9. Space - Wikipedia

    en.wikipedia.org/wiki/Space

    Abstract space is a term used in geography to refer to a hypothetical space ... for example, visual space. ... what he terms the "time-space compression."
