Passive Gravitational Mass

Famous quotes containing the words passive and/or mass:

    We have not passed that subtle line between childhood and adulthood until we move from the passive voice to the active voice—that is, until we have stopped saying “It got lost,” and say, “I lost it.”
    Sydney J. Harris (b. 1917)

    There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.
    Ralph Waldo Emerson (1803–1882)
