Famous quotes containing the words direct and/or measuring:
“No direct hit to smash the shatter-proof
And lodge at last the quivering needle
Clean in the eye of one who stands transfixed
In fascination of her brightness.”
—Karl Shapiro (b. 1913)
“Man always made, and still makes, grotesque blunders in selecting and measuring forces, taken at random from the heap, but he never made a mistake in the value he set on the whole, which he symbolized as unity and worshipped as God. To this day, his attitude towards it has never changed, though science can no longer give to force a name.”
—Henry Brooks Adams (1838–1918)
