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)

    ... in the happy laughter of a theatre audience one can get the most immediate and numerically impressive guarantee that there is nothing in one’s mind which is not familiar to the mass of persons living at the time.
    Rebecca West (1892–1983)
