Many of our daily activities are based on the time, programming events and tasks thanks to this measure, so watches have become an indispensable complement of our life.
But these clocks depend on approaches and idea that we have of time, namely they are not exact and they require adjustment time not to mention of course changing the batteries if you need them, but what if we could have a watch that is not loose and requires no batteries for a period of 16,000 million years?.
Redefining the concept of “second”
Hidetoshi Katori, Professor of the University of Tokyo, along with a group of researchers have developed what they have called “Cryogenic optical networks watches” which seem a great futuristic machine, but not a clock as we know it, and it is that its accuracy makes them rely on technology that is currently not even able to be measured.
These watches even surpass in accuracy to the cesium atomic clock presented in August by 2013, which maintained its accuracy by “only” 13,800 years, time that took you to loosen a second.
These clocks operate through a special laser that captures atoms of strontium in small structures in the form of networks, this is capable of measuring the frequency of vibration of the atoms making a kind of pendulum Atomic.
Because of its components and the delicate design, these watches should operate in a cold environment of approximately -180 degrees centigrade, this with the intention of reducing the impact of electromagnetic waves and thus maintain the accuracy of the machine at all times.
The capacity of precision of these watches offers something never seen before, since it is capable of keep the time for up to 16,000 million years, even more than what is expected be of life land, thus giving a new definition to what we know as “second”.
But rather than offer “the hour” without fail and without adjustments, the important part of this development are its diverse applications, since it could be used within systems of global positioning satellites and communications networks, as well as to assist in various technologies of precision.
