Material Time Derivative

Famous quotes containing the words material, time and/or derivative:

    It may be possible to do without dancing entirely. Instances have been known of young people passing many, many months successively, without being at any ball of any description, and no material injury accrue either to body or mind; Mbut when a beginning is made—when felicities of rapid motion have once been, though slightly, felt—it must be a very heavy set that does not ask for more.
    Jane Austen (1775–1817)

    Time rushes by and yet time is frozen. Funny how we get so exact about time at the end of life and at its beginning. She died at 6:08 or 3:46, we say, or the baby was born at 4:02. But in between we slosh through huge swatches of time—weeks, months, years, decades even.
    Helen Prejean (b. 1940)

    Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.
    Henry David Thoreau (1817–1862)
