Actual Exhaust Velocity

Famous quotes containing the words actual and/or exhaust:

    But in the reception of metaphysical formula, all depends, as regards their actual and ulterior result, on the pre-existent qualities of that soil of human nature into which they fall—the company they find already present there, on their admission into the house of thought.
    Walter Pater (1839–1894)

    Language is like soil. However rich, it is subject to erosion, and its fertility is constantly threatened by uses that exhaust its vitality. It needs constant re-invigoration if it is not to become arid and sterile.
    Elizabeth Drew (1887–1965)
