Atomic clocks with a precision of a nano-second! This is pretty accurate by anybody’s standards.
Atomic clocks are already installed on many devices, such as GPS, but soon they can gain a place in our daily lives if they are smaller and cheaper.
In the near future, these watches can appear only a few centimeters in size and cost less than 100 euros.
A team of physicists from the National Institute of Standards and Technology (NIST), located in Boulder, Colorado, has developed a technique to miniaturize an atomic clock that can fit in cubic centimeters. Would this mean having hours on your wrist that derive less than a nanosecond per day? Now, for you or me, this precision is more than enough.
However, the number of devices we use every day with this high precision internal clock will increase steadily. Therefore, the sending of digital “pulses” to synchronize all these devices will increase significantly, which may lead to the fact that “air waves will saturate”.
“The more information circulates in the network, the more accurate the timing and accuracy of these synchronization pulses will be. “The International Telecommunications Union recommends synchronizing the network with a precision of one part for 300 billion,” writes Tony Jones in his book on time measurement. Similarly, systems for position measurement (eg, GPS) are synchronized more accurately than similar time tracking devices.
One can imagine that the utility of an atomic clock is becoming less expensive.
However, in modern atomic clock for pc desktop, microwaves are used, creating the phenomenon of the resonance frequency for a given amount of cesium. This frequency is very stable and only counts these vibrations 9192631770 per second. However, the problem is that these microwaves have a wavelength of approximately 3 centimeters, which can not be properly distributed in cavities smaller than this length. To successfully reduce the size of the case where cesium is set, the use of smaller particles of the radiation wavelength is the answer, and this is where technology aims to use this clock as usual.
Another thing to think about is whether there really is a demand for high precision watches, what are the advantages of a precise estimate of nanoseconds? However, regardless of demand, as in all technological advances, technology seems to simply do so, because it may be the nature of the human race, the reason why we read this article here on a PC screen somewhere.
