Zeitintervall – Wikipedia
A Time interval – also Time interval , Period , Duration , Period of time , Period , Time phase or Period – is part of the current time. A time interval ranges from its zero point, which is set by a special, individually known event, up to a later event as an end point. A time unit is required for quantitative information.
The designation Interval goes to the Latin name between the vallos for the local distance “between the palisades” [first] And stands here by a figurative importance for the time interval between two consecutive events. A time interval has a beginning and an end, which can be determined by a time. This means that a time interval can be understood as a time difference.
In addition to the generally observable time intervals – such as the between two sunrises as a full day, or that between two sunscape stalls as a tropical year or the time interval of the nuclear second – numerous specific time spans are measured in today’s natural sciences: for example, the lifespan for radioactive decay or the generation time between Two cell divisions for calculating the growth rate of a tissue or the time when a foucault pendulum travels an angle of one degree to determine the earth’s earth.
The shortest period of importance in modern physics is the one named after the physicist Max Planck Planck time (about 10 −43 s), which at the same time represents the definition limit of the time continuum. The shortest experimentally reproducible time interval (as of 2020) is the period of time that a photon needs to cross a hydrogen atom: around 0.25 Attoseconds (2.5 · ten −19 s), [2] about the 2 · ten 25 -times the Planck time. The longest physically determinable period of time is the one of the past, as a world age, about 14 billion years or 4.4 · ten 17 Seconds. The age of the earth is estimated at about 4.6 billion years, their history is differentiated in different lengths of time (see geological time scale).
A period of neuropsychologically is the duration that we subjectively experience as a present and in which we impress now Take together. According to various studies, this range should take around three seconds and be divided into about a hundred shares, which include intervals of around 30 ms (and thus above the synaptic latency of excitation transmission on fast chemical synapses). For example, up to 0.03 seconds, short noises can still be distinguished according to their order and dissolved as a sequence (see also personal equation for temporal reference).
