Convected Time Derivative

Famous quotes containing the words time and/or derivative:

    We New Yorkers see more death and violence than most soldiers do, grow a thick chitin on our backs, grimace like a rat and learn to do a disappearing act. Long ago we outgrew the need to be blowhards about our masculinity; we leave that to the Alaskans and Texans, who have more time for it.
    Edward Hoagland (b. 1932)

    When we say “science” we can either mean any manipulation of the inventive and organizing power of the human intellect: or we can mean such an extremely different thing as the religion of science the vulgarized derivative from this pure activity manipulated by a sort of priestcraft into a great religious and political weapon.
    Wyndham Lewis (1882–1957)
