Actual Error Covariance

Famous quotes containing the words actual and/or error:

    There is something else which has the power to awaken us to the truth. It is the works of writers of genius.... They give us, in the guise of fiction, something equivalent to the actual density of the real, that density which life offers us every day but which we are unable to grasp because we are amusing ourselves with lies.
    Simone Weil (1909–1943)

    Truth on our level is a different thing from truth for the jellyfish, and there must certainly be analogies for truth and error in jellyfish life.
    —T.S. (Thomas Stearns)
