Material Time Derivative

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

    Would it not be worth while to discover nature in Milton? be native to the universe? I, too, love Concord best, but I am glad when I discover, in oceans and wildernesses far away, the material of a million Concords: indeed, I am lost, unless I discover them.
    Henry David Thoreau (1817–1862)

    There are times when words seem empty and only actions seem great. Such a time has come, and in the Providence of God America will once more have an opportunity to show the world that she was born to save mankind.
    Woodrow Wilson (1856–1924)

    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)
