Many of our daily activities are based on time, scheduling events and tasks thanks to this measure, so the watcheshave become an indispensable complement of our life.
But these watches depend on the approximations and idea we have of time, that is to say they are not accurate and require adjustments from time to time without mentioning of course the change of batteries in case of requiring them, but what would happen if we could have a watch that did not Is maladjusted and does not require batteries for a period of 16,000 million years?
Redefining The Concept Of “Second”
Hidetoshi Katori , a professor at the University of Tokyo, together with a group of researchers have succeeded in developing what they have called “cryogenic optical network clocks” which look like a great futuristic machine, but not a clock as we know it, Accuracy makes them rely on technology that at present is not even capable of being measured.
These clocks even outperform the cesium atomic clock introduced in August in 2013, which maintained its accuracy for “only” 13,800 years, which it took time to misfit a second.
These clocks work through a special laser that traps strontium atoms in small structures in the form of nets, with this is able to measure the frequency of vibration of the atoms making a kind of atomic pendulum.
Due to its components and delicate design, these watches must operate in a cold environment of approximately-180 degrees Celsius, this with the intention of reducing the impact of electromagnetic waves and thus maintain at all times the precision of the machine.
The precision capability of these watches offers something never before seen, since it is able to maintain the time for up to 16,000 million years, time even greater than what is expected to have life of the Earth, thus giving a new definition to what We know as “second”.
But beyond offering “the hour” without failures and without adjustments, the important thing of this development are its diverse applications, since it could serve within systems of global positioning of satellites and networks of communication, as well as to help in diverse Precision technologies.
