Famous quotes containing the words calculator and/or watch:
“Man is a stream whose source is hidden. Our being is descending into us from we know not whence. The most exact calculator has no prescience that somewhat incalculable may not balk the very next moment. I am constrained every moment to acknowledge a higher origin for events than the will I call mine.”
—Ralph Waldo Emerson (1803–1882)
“I think a lot of people believe I’m going to fall flat on my face, and they’re still waiting for it to happen. I hope they wait forever, and I hope they keep coming to watch me.”
—Christine Wren, U.S. baseball umpire. As quoted in WomenSports magazine, p. 15 (October 1975)
