Water Pressure Difference

Famous quotes containing the words water, pressure and/or difference:

    The work of the world is common as mud.
    Botched, it smears the hands, crumbles to dust.
    But the thing worth doing well done
    has a shape that satisfies, clean and evident.
    ...
    The pitcher cries for water to carry
    and a person for work that is real.
    Marge Piercy (b. 1936)

    Today’s pressures on middle-class children to grow up fast begin in early childhood. Chief among them is the pressure for early intellectual attainment, deriving from a changed perception of precocity. Several decades ago precocity was looked upon with great suspicion. The child prodigy, it was thought, turned out to be a neurotic adult; thus the phrase “early ripe, early rot!”
    David Elkind (20th century)

    The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.
    Ralph Waldo Emerson (1803–1882)
