Famous quotes containing the words missing and/or data:
“We ourselves feel that what we are doing is just a drop in the ocean. But if that drop was not in the ocean, I think the ocean would be less because of that missing drop. I do not agree with the big way of doing things.”
—Mother Teresa (b. 1910)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
