  2. Spacetime diagram - Wikipedia

    en.wikipedia.org/wiki/Spacetime_diagram

    Therefore, the observer at A with the black axes notices their clock as reading the distance from O to A while they observe the clock moving relative him or her to read the distance from O to B. Due to the distance from O to B being smaller than the distance from O to A, they conclude that the time passed on the clock moving relative to them is ...

  3. Clockwise - Wikipedia

    en.wikipedia.org/wiki/Clockwise

    Clockwise motion (abbreviated CW) proceeds in the same direction as a clock's hands relative to the observer: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in Commonwealth English ) anticlockwise ( ACW ) or (in North American English ) counterclockwise ( CCW ...

  4. Longitude by chronometer - Wikipedia

    en.wikipedia.org/wiki/Longitude_by_chronometer

    The observer is somewhere along the position line. Time sight is a general method for determining longitude by celestial observations using a chronometer; these observations are reduced by solving the navigational triangle for meridian angle and require known values for altitude, latitude, and declination; the meridian angle is converted to ...

  5. Gravitational time dilation - Wikipedia

    en.wikipedia.org/wiki/Gravitational_time_dilation

    If an observer is able to track the light in a remote, distant locale which intercepts a remote, time dilated observer nearer to a more massive body, that first observer tracks that both the remote light and that remote time dilated observer have a slower time clock than other light which is coming to the first observer at c, like all other ...

  6. Sector clock - Wikipedia

    en.wikipedia.org/wiki/Sector_clock

    The United States Army Air Force (USAAF) adapted the RAF sector clock using a coloured block pattern in place of triangles. [3] Sector clocks are sought after by collectors of militaria/aeronautica. (The clock face design also appears on wrist watches commemorating the wartime role of the sector clock).

  7. Clock position - Wikipedia

    en.wikipedia.org/wiki/Clock_position

    The observer then measures or observes the angle made by the intersection of the line of sight to the longitudinal axis, the dimension of length, of the vessel, using the clock analogy. In this analogy, the observer imagines the vessel located on a horizontal clock face with the front at 12:00.

  9. Rindler coordinates - Wikipedia

    en.wikipedia.org/wiki/Rindler_coordinates

    These hyperbolic coordinates can be separated into two main variants depending on the accelerated observer's position: If the observer is located at time T = 0 at position X = 1/α (with α as the constant proper acceleration measured by a comoving accelerometer), then the hyperbolic coordinates are often called Rindler coordinates with the ...
