Famous quotes containing the word physics:

    “Mathematics should be mixed not only with physics but with ethics.”
    —Henry David Thoreau (1817–1862)

    “He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
    —Henry David Thoreau (1817–1862)

    “... it is as true in morals as in physics that all force is imperishable; therefore the consequences of a human action never cease.”
    —Tennessee Claflin (1846–1923)
