  2. Thaumatrope - Wikipedia

    en.wikipedia.org/wiki/Thaumatrope

    The toy has traditionally been thought to demonstrate the principle of persistence of vision, a disputed explanation for the cause of illusory motion in stroboscopic animation and film. Examples of common thaumatrope pictures include a bare tree on one side of the disk, and its leaves on the other, or a bird on one side and a cage on the other.

  3. Persistent world - Wikipedia

    en.wikipedia.org/wiki/Persistent_world

    A form of simulated persistence referred to as "pseudo-persistence" has been used in both video games and pervasive games. Pseudo-persistence means making relevant world data available when the relevant players reconnect to the world instance. In a mobile game, a virtual world might exist on a distributed collection of mobile devices.

    Persistence (discontinuity), a concept in geotechnical engineering; Persistence (linguistics), a principle of grammaticalization; Persistence (psychology), a personality trait; Persistence of vision, a theory on how the illusion of motion in films is achieved; Persistence forecasting, predicting the future to be the same as the present

  5. Persistence of vision - Wikipedia

    en.wikipedia.org/wiki/Persistence_of_vision

    Persistence of vision is the optical illusion that occurs when the visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. [1] The illusion has also been described as "retinal persistence", [2] "persistence of impressions", [3] simply "persistence" and other variations ...

    en.wikipedia.org/wiki/Attention_span

    Another study examining the relations between children’s attention span-persistence in preschool and later academic achievements found that children’s age four attention span-persistence significantly predicted math and reading achievement at age 21 after controlling for achievement levels at age seven, adopted status, child vocabulary ...

  7. Persistent, bioaccumulative and toxic substances - Wikipedia

    en.wikipedia.org/wiki/Persistent,_bio...

    The persistence of these compounds is due to the high resistance to oxidation, reduction, addition, elimination and electrophilic substitution. [6] The toxicological interactions of PCBs are affected by the number and position of the chlorine atoms, without ortho substitution are referred as coplanar and all others as non-coplanar. [5]

  8. Endurantism - Wikipedia

    en.wikipedia.org/wiki/Endurantism

    Endurantism or endurance theory is a philosophical theory of persistence and identity. According to the endurantist view, material objects are persisting three-dimensional individuals wholly present at every moment of their existence, which goes with an A-theory of time.

  9. Perdurantism - Wikipedia

    en.wikipedia.org/wiki/Perdurantism

    Perdurantism or perdurance theory is a philosophical theory of persistence and identity. [1] The debate over persistence currently involves three competing theories—one three-dimensionalist theory called "endurantism" and two four-dimensionalist theories called "perdurantism" and "exdurantism".
