Time

Time is a dimension in which events can be ordered from the past through the present into the future, and also the measure of durations of events and the intervals between them. Time has long been a major 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, music, dance, and the live theater all incorporate some notion of time into their respective measuring systems. Some simple, relatively uncontroversial definitions of time include "time is what clocks measure" and "time is what keeps everything from happening at once".

Famous quotes containing the word time:

    For WAR, consisteth not in Battle only, or the act of fighting; but in a tract of time, wherein the Will to content by Battle is sufficiently known.... So the nature of War, consisteth not in actual fighting; but in the known disposition thereto, during all the time there is no assurance to the contrary. All other time is PEACE.
    Thomas Hobbes (1579–1688)

    Women have a hard time of it in this world. They are oppressed by man-made laws, man-made social customs, masculine egoism, the delusion of masculine superiority. Their one comfort is the assurance that, even though it may be impossible to prevail against man, it is always possible to enslave and torture a man.
    —H.L. (Henry Lewis)

    The mere existence of an additional child or children in the family could signify Less. Less time alone with parents. Less attention for hurts and disappointments. Less approval for accomplishments. . . . No wonder children struggle so fiercely to be first or best. No wonder they mobilize all their energy to have more or most. Or better still, all.
    Adele Faber (20th century)
