Many of us must have thought that somewhere on our planet must be the most accurate, most important watches that compare time around the world, including orbiting satellites, on the Internet and in various scientific experiments, requiring the most accurate calculation of even the smallest fraction seconds.
There really is such a device. They are today reference atomic clock developed last year by Japanese by scientists. They are able to almost unmistakably show the time during sixteen billion years, making over this period perhaps the error is only one second.
However, very soon the primacy in this matter may convey the new invention of American specialists. To employees University of California Los Angeles managed to create ultra-precise optical watches with small dimensions and showing truly phenomenal accuracy. Device, presumably does not go astray in his work for a hundred billion years, while it allows you to divide the second into two hundred seventy quadrillion parts! It’s hard to believe, but that’s according to the words authors of the invention, indeed.

Optical watches are considered much more reliable and error-free. in comparison with atomic. Atomic chronometers are used as a kind of pendulum the natural vibrations of molecules and atoms, in while optical ones rely on the movement of photon fluxes, that is, the movement of light. Earlier ultra-precise optical watches occupied entire premises, and huge, but a new brainchild California inventors has dimensions of just one square centimeter, which allows you to easily transport innovation and integrate it into various techniques.
Why do we need ultra-precise watches?
Such a chronometer allows you to produce so accurate measuring various values of the space-time continuum, that his invention automatically marked the emergence of a new section of science – attosecond physics. Specialists in this field will certainly be engaged in the study of processes in the universe, occurring so fast that the human brain just unable to comprehend them, and compared with life expectancy any living creature, these processes practically do not occur.
Today, when the most accurate watches are still considered atomic, the time for which cesium atom makes 9 192 631 770 cycles of natural vibrations. However, the optical watches created by the Americans turned out to be so much more perfect that scientists seriously thought about revising the duration of a second. Why, we ask, is necessary?

Figuratively speaking, so that someday you do not have to one-time enter the calendar on the thirty-second of may, as it did famous baron Munchausen. However, Russian scientists have long been determined that in the tragicomedy of Mark Zakharov this problem was very hyperbolic, and in fact, even with not the most accurate hours, over a dozen billion years will accumulate no more than two minutes “extra” time. But still accumulate, and scientists such errors do not favor.
Proud of their achievement, the truth, while not in a hurry revise the value of a second. Yet this, you see, is not a question of paramount importance although the innovative optical chronometer already in theory allows you to transfer humanity to the most accurate time. But suddenly our descendants will invent even more exemplary watches or create a society in which a constant count of time will cease to be an urgent need. For example, thanks the quantum transition in which we supposedly live since 2013, time, what we consider him to lose for humanity value…
