Water Pressure Difference

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

    It is the work of a brave man surely, in whom there was no guile! He rounded this water with his hand, deepened and clarified it in his thought, and in his will bequeathed it to Concord. I see by its face that it is visited by the same reflection; and I can almost say, Walden, is it you?
    Henry David Thoreau (1817–1862)

    The area [of toilet training] is one where a child really does possess the power to defy. Strong pressure leads to a powerful struggle. The issue then is not toilet training but who holds the reins—mother or child? And the child has most of the ammunition!
    Dorothy Corkville Briggs (20th century)

    The difference between a photograph and even the most realistic painting—say, one of Courbet’s landscapes—is that in the latter there has been selection, emphasis and some discreet distortion. The painter’s deep instinctive feeling for mass and force has rearranged everything.
    Gerald Branan (1894–1987)
