  2. Event (relativity) - Wikipedia

    en.wikipedia.org/wiki/Event_(relativity)

    For example, a glass breaking on the floor is an event; it occurs at a unique place and a unique time. [1] Strictly speaking, the notion of an event is an idealization , in the sense that it specifies a definite time and place, whereas any actual event is bound to have a finite extent, both in time and in space.

  3. Happening - Wikipedia

    en.wikipedia.org/wiki/Happening

    One definition comes from Wardrip-Fruin and Montfort in The New Media Reader, "The term 'happening' has been used to describe many performances and events, organized by Allan Kaprow and others during the 1950s and 1960s, including a number of theatrical productions that were traditionally scripted and invited only limited audience interaction."

  4. Coincidence - Wikipedia

    en.wikipedia.org/wiki/Coincidence

    Usually, coincidences are chance events with underestimated probability. [3] An example is the birthday problem, which shows that the probability of two persons having the same birthday already exceeds 50% in a group of only 23 persons. [4] Generalizations of the birthday problem are a key tool used for mathematically modelling coincidences. [5]

    This means that this "unlikely event" has a probability of 63.23% of happening if 1,000 independent trials are conducted. If the number of trials were increased to 10,000, the probability of it happening at least once in 10,000 trials rises to ( 1 − 0.999 10000 ≈ 0.99995, or ) 99.995%. In other words, a highly unlikely event, given enough ...

  6. Relativity of simultaneity - Wikipedia

    en.wikipedia.org/wiki/Relativity_of_simultaneity

    The Lorentz-transform calculation above uses a definition of extended-simultaneity (i.e. of when and where events occur at which you were not present) that might be referred to as the co-moving or "tangent free-float-frame" definition. This definition is naturally extrapolated to events in gravitationally-curved spacetimes, and to accelerated ...

  7. Geological event - Wikipedia

    en.wikipedia.org/wiki/Geological_event

    Geological events range in time span by orders of magnitude, from seconds to millions of years, and in spatial scale from local to regional and, ultimately, global. [2] In contrast to chronostratigraphic or geochronological units, that define the boundaries between periods , epochs and other units of the geologic time scale , complex dynamic ...

    Examples include: sunrise, weather, fog, thunder, ... natural phenomena have been observed by a series of countless events as a feature created by nature.
