!!! Overview[1]
[{$pagename}] is the indefinite continued progress of existence and [events] that occur in apparently irreversible succession from the past through the present to the future.[{$pagename}] is one of the seven fundamental physical quantities [International System of Quantities]
[{$pagename}] is not helpful without a [Date] and may be referred to as [DateTime][{$pagename}] is a fact of life that not all events in our universe happen concurrently - instead, there is a certain order. Defining a [{$pagename}] coordinate or defining [{$pagename}], the way physicists do it, is to define a prescription to associate with each [event] a number so as to reflect that order - if event B happens after event A, then the number associated with B should be larger than that associated with A. !! [Proper Time]
[Proper Time] along a timelike world line is defined as the time as measured by a clock following that line and is thus independent of coordinates, and is a Lorentz [scalar].
[Proper Time] could be described as the time on your wrist watch.
Perhaps of greater interest is the Proper Time Interval which is the interval between any two [events].
!! [now]
[now] (or [Simultaneity]) is something we rarely think about - we just accept it as a fact of life. However, thinking matters through, it isn't obvious at all how one can determine whether or not two events at two different locations happen simultaneously, or not.
