Famous quotes containing the word physics:

    “The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.”
    —Nancy Cartwright (b. 1945)

    “... 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)

    “Although philosophers generally believe in laws and deny causes, explanatory practice in physics is just the reverse.”
    —Nancy Cartwright (b. 1945)
