DATA are measured values, the results of our observations. To show one use, this example: The IDEA that an atomic bomb might or might not work became, as they say, “with the wave of a wand” or “overnight” an INNER CONVICTION that it did work when the DATA appeared, how two atomic explosions in Japan helped end World War II at the cost of a large number of human lives.
