  2. Timekeeping on Mars - Wikipedia

    en.wikipedia.org/wiki/Timekeeping_on_Mars

    The Mars time of noon is 12:00 which is in Earth time 12 hours and 20 minutes after midnight. For the Mars Pathfinder, Mars Exploration Rover (MER), Phoenix, and Mars Science Laboratory missions, the operations teams have worked on "Mars time", with a work schedule synchronized to the local time at the landing site on Mars, rather than the ...

  3. Time–space compression - Wikipedia

    en.wikipedia.org/wiki/Time–space_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 ...

  4. Mars sol - Wikipedia

    en.wikipedia.org/wiki/Mars_sol

    Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars. A sol is slightly longer than an Earth day.

  5. Epoch - Wikipedia

    en.wikipedia.org/wiki/Epoch

    An epoch in computing is the time at which the representation is zero. For example, Unix time is represented as the number of seconds since 00:00:00 UTC on 1 January 1970, not counting leap seconds. An epoch in astronomy is a reference time used for consistency in

  6. 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]

  7. Hesperian - Wikipedia

    en.wikipedia.org/wiki/Hesperian

    The Hesperian is a geologic system and time period on the planet Mars characterized by widespread volcanic activity and catastrophic flooding that carved immense outflow channels across the surface. The Hesperian is an intermediate and transitional period of Martian history.

  8. Sociological theory - Wikipedia

    en.wikipedia.org/wiki/Sociological_theory

    Pure sociology is a theoretical paradigm, developed by Donald Black, that explains variation in social life through social geometry, meaning through locations in social space. A recent extension of this idea is that fluctuations in social space—i.e., social time —are the cause of social conflict.

  9. Time reversibility - Wikipedia

    en.wikipedia.org/wiki/Time_reversibility

    A mathematical or physical process is time-reversible if the dynamics of the process remain well-defined when the sequence of time-states is reversed.. A deterministic process is time-reversible if the time-reversed process satisfies the same dynamic equations as the original process; in other words, the equations are invariant or symmetrical under a change in the sign of time.
