Entropy (arrow of Time) - The Arrow of Time in Various Phenomena

The Arrow of Time in Various Phenomena

All phenomena that behave differently in one time direction can ultimately be linked to the Second Law of Thermodynamics. This includes the fact that ice cubes melt in hot coffee rather than assembling themselves out of the coffee, that a block sliding on a rough surface slows down rather than speeding up, and that we can remember the past rather than the future. This last phenomenon, called the "psychological arrow of time", has deep connections with Maxwell's demon and the physics of information; In fact, it is easy to understand its link to the Second Law of Thermodynamics if one views memory as correlation between brain cells (or computer bits) and the outer world. Since the Second Law of Thermodynamics is equivalent to the growth with time of such correlations, then it states that memory will be created as we move towards the future (rather than towards the past).

Famous quotes containing the words arrow, time and/or phenomena:

    ... and the next summer she died in childbirth.
    That’s all. Of course, there may be some sort of sequel but it is not known to me. In such cases instead of getting bogged down in guesswork, I repeat the words of the merry king in my favorite fairy tale: Which arrow flies for ever? The arrow that has hit its mark.
    Vladimir Nabokov (1899–1977)

    “The time has come,” the Walrus said,
    “To talk of many things:
    Of shoes—and ships—and sealing wax—
    Of cabbages—and kings—
    And why the sea is boiling hot—
    And whether pigs have wings.”
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    The television screen, so unlike the movie screen, sharply reduced human beings, revealed them as small, trivial, flat, in two banal dimensions, drained of color. Wasn’t there something reassuring about it!—that human beings were in fact merely images of a kind registered in one another’s eyes and brains, phenomena composed of microscopic flickering dots like atoms. They were atoms—nothing more. A quick switch of the dial and they disappeared and who could lament the loss?
    Joyce Carol Oates (b. 1938)
