-the “indefinite continued ‘progress’ of ‘existence’ + ‘events’ that occur in apparently irreversible succession from the ‘past’ through the ‘present’ to the ‘future'”-
.
(‘time’ is a ‘component quantity’ of various ‘measurements’ used to sequence ‘events’, to compare the ‘duration’ of ‘events’ or the ‘intervals’ between them, and to quantify ‘rates of change’ of ‘quantities’ in ‘material reality’ or in the ‘conscious experience’)
(‘time’ is often referred to as the ‘4th dimension’, along with the 3 ‘spatial dimensions’)
(‘time’ has long been an important subject of study in ‘religion’, ‘philosophy’, and ‘science’, but defining it in a manner applicable to all ‘fields’ without ‘circularity’ has consistently eluded scholars)
(nevertheless, diverse fields such as ‘business’, ‘industry’, ‘sports’, ‘the sciences’, and ‘the performing arts’ all incorporate some notion of ‘time’ into their respective ‘measuring systems’)
(2 contrasting viewpoints on ‘time’ divide prominent ‘philosophers’)
(1 view is that ‘time’ is part of the fundamental structure of the ‘universe’—a ‘dimension’ independent of ‘events’, in which ‘events’ occur ‘in sequence’)
(‘isaac newton’ subscribed to this ‘realist view’, and hence it is sometimes referred to as ‘newtonian time’)
(the opposing view is that time does not refer to any kind of “container” that ‘events’ and ‘objects’ “move through”, nor to any entity that “flows”, but that it is instead part of a fundamental intellectual ‘structure’ (together with ‘space’ and ‘number’) within which humans ‘sequence’ and ‘compare’ ‘events’)
(this 2nd view, in the tradition of ‘gottfried leibniz‘ and ‘immanuel kant’, holds that time is neither an ‘event’ nor a ‘thing’, and thus is “not itself measurable nor can it be traveled”)
(‘time’ in ‘physics’ is ‘unambiguously operationally defined’ as “what a clock reads”)
(‘time’ is one of the “7 fundamental physical quantities” in both the ‘international system of units’ + ‘international system of quantities’)
(‘time’ is used to define other quantities (such as ‘velocity’) so defining ‘time’ in terms of such quantities would result in ‘circularity of definition’)
(an operational definition of ‘time’, wherein one says that observing a certain # of ‘repetitions’ of one or another ‘standard cyclical event’ (such as ‘the passage of a free-swinging pendulum’) constitutes 1 standard ‘unit’ such as the second, is highly useful in the conduct of both ‘advanced experiments’ and ‘everyday affairs of life’)
(the ‘operational definition’ leaves aside the question whether there is something called ‘time’, apart from the ‘counting activity’ just mentioned, that ‘flows’ and that can be ‘measured’)
(investigations of a single continuum called ‘spacetime’ bring questions about ‘space’ into questions about ‘time’, questions that have their roots in the works of early students of ‘natural philosophy’)
(furthermore, it may be that there is a subjective component to time, but whether or not ‘time’ itself is “felt” (as a ‘sensation’) or is a ‘judgment’, is a ‘matter of debate’)
(‘temporal measurement’ has occupied scientists and technologists, and was a prime motivation in navigation and ‘astronomy’)
(‘periodic events’ and ‘periodic motion’ have long served as standards for units of ‘time’)
(examples include the ‘apparent motion of the sun across the sky’, the ‘phases of the moon’, the ‘swing of a pendulum’, and the ‘beat of a heart’)
(currently, the international unit of time, the ‘second’, is defined by measuring the ‘electronic transition frequency’ of ‘caesium atoms’)
.
(‘time’ is also of significant social importance, having economic value (“time is money”) as well as personal value, due to an awareness of the limited time in each day and in ‘human life spans’)
