Accurate time affects much more than just getting to lunch on time or five minutes early.
Transportation, communication, manufacturing, electric power, and other technologies are all extremely dependent on time. As our obsession with time grows, we race to find the most accurate way to measure it. Scientists have been working on a solution to this problem for decades. And they have found the beginning of an answer. While pendulums and crystal quartz clocks are thought to have been very accurate, they are affected by the environment that surrounds them.
