Measurement is arguably the basis of all civilization. We are born into this world measuring our environment and trying to understand it and we continue measuring for the rest of our lives. All of our measurements should rely on standards that ideally are accurate, unchanging, and universally defined. While such a solid foundation for our measurement systems has been dream since before the time of the French Revolution, it is only with the dawn of the quantum age that it could be realized. As a result, humankind just recently achieved an advance that goes beyond the level of a once-in-a-lifetime event, it achieved an advance that, hopefully, is just a once-on-a-planet event. I hope to convey the momentousness of what just occurred.
