When we think of time, we think of clock time. Action all around the world is synchronized by clock time, starting with train schedules, worldwide plane schedules, navigation, astronomy, worldwide telecommunication, etc. These depend completely on accurate timing. The accuracy standards of timekeeping devices have been increasing rapidly due to the demands for more and more accurate timing for space communication, navigation, astronomy, etc. Rather than use mechanical clocks, we are relying nowadays on "atomic clocks." This is not a clock in the usual sense but a device that uses the very stable oscillation of the cesium atoms as a standard for timekeeping.
From grandfather clocks to wristwatches, all these clocks are supposed to chop up for us the 24 hours of the day more or less reliably into hours, minutes, and seconds. Let\'s call this kind of time "objective" since everybody\'s watches are supposed to cut time into slices of even thickness.
However, we know to personal experience that time does not "feel" as passing evenly under different circumstances. When pursuing some interesting activity, time "flies"; while waiting in the dentist\'s office, it "drags." When Einstein was once asked about this "psychological time," he replied with a now famous observation: "When you spend two hours with a nice girl, you think it\'s only a minute. But when you sit on a hot stove for a minute, you think it\'s two hours." Realizing the relativity of time, let us
see, then, how this subjective time can be put to some use.
