Famous quotes containing the words measuring and/or devices:
“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)
“So that with much ado I was corrupted, and made to learn the dirty devices of this world.
Which now I unlearn, and become, as it were, a little child again that I may enter into the Kingdom of God.”
—Thomas Traherne (1636–1674)
