Famous quotes containing the words atomic and/or clock:
“Take adultery or theft.
Merely sins.
It is evil who dines on the soul,
stretching out its long bone tongue.
It is evil who tweezers my heart,
picking out its atomic worms.”
—Anne Sexton (1928–1974)
“We are hardly ever grateful for a fine clock or watch when it goes right, and we pay attention to it only when it falters, for then we are caught by surprise. It ought to be the other way about.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
