Famous quotes containing the word physics:

    “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)

    “But this invites the occult mind,
    Cancels our physics with a sneer,
    And spatters all we knew of denouement
    Across the expedient and wicked stones.”
    —Karl Shapiro (b. 1913)
