Time, despite the fact that scientists still cannot finally unravel its true essence, still has its own units of measurement established by mankind. And a device for calculating, called a clock. What are their varieties, what is the most accurate clock in the world? This will be discussed in our material today.
Which is the most accurate clock in the world?
They are considered to be atomic - they have tiny errors that can reach only a second in a billion years. The 2nd, no less honorable, pedestal is won by quartz watches. They are only 10-15 seconds behind in a month or in a hurry. But mechanical watches are not the most accurate in the world. They need to be wound up and down all the time, and here the errors are of a completely different order.
The most accurate atomic clock in the world
As already mentioned, atomic instruments for qualitative time measurement are so scrupulous that the errors given by them can be compared withmeasurements of the diameter of our planet exactly to each microparticle. Undoubtedly, the average layman in everyday life does not need such precise mechanisms at all. These are used by researchers from science to conduct various experiments where limiting calculation is required. They provide an opportunity for people to check the "course of time" in various regions of the globe or to conduct experiments that confirm the general theory of relativity, as well as other physical theories and hypotheses.
Paris Standard
What is the most accurate clock in the world? It is customary to consider them Parisian, belonging to the Institute of Time. This device is the so-called standard of time, people all over the world are checked against it. By the way, in fact, it does not quite look like “walkers” in the traditional sense of the word, but resembles the most accurate device of the most complex design, which is based on the quantum principle, and the main idea is the calculation of space-time using particle oscillations with errors equal to only 1 second per 1000 years.
Even more precise
Which is the most accurate watch in the world today? In the current realities, scientists have invented a device that is 100 thousand times more accurate than the Paris standard. Its error is one second in 3.7 billion years! A group of physicists from the USA is responsible for the production of this technique. It is already the second version of devices for time, built on quantum logic, where information processing is carried out according to a method similar, for example, to quantum computers.
Research Help
The latest quantum devices not only set other standards in the measurement of such a quantity as time, but also help researchers in many countries to resolve some issues that are associated with such physical constants as the speed of a light beam in a vacuum or Planck's constant. The increasing accuracy of measurements is favorable for scientists, who hope to track down time dilation caused by gravity. And one of the technology companies in the US plans to launch even serial quantum watches for everyday use. True, how high will their initial value be?
Operation principle
Atomic clocks are also called quantum clocks, because they operate on the basis of processes that occur at the molecular levels. To create high-precision devices, not all atoms are taken: the use of calcium and iodine, cesium and rubidium, and also hydrogen molecules is usually typical. At the moment, the most accurate mechanisms for calculating time based on yttiberium, they were produced by the Americans. More than 10 thousand atoms are involved in the work of the equipment, and this ensures excellent accuracy. By the way, the record-breaking predecessors had an error per second of “only” 100 million, which, you see, is also a considerable time.
Precise quartz…
When choosing household "walkers" for everyday use, of course, nuclear devices should not be taken into account. Of the household watches today, the most accurate clock in the world is quartz, which, moreover, has a number of advantages in comparison with mechanical ones:require a factory, work with the help of crystals. Their running errors average 15 seconds per month (mechanical ones can usually lag by this amount of time per day). And the most accurate wrist watch in the world of all quartz watches, according to many experts, is Citizen's Chronomaster. They can have an error of only 5 seconds per year. In terms of cost, they are quite expensive - within 4 thousand euros. On the second step of an imaginary Longines podium (10 seconds per year). They are already much cheaper - about 1000 euros.
…and mechanical
Most mechanical time measuring instruments are generally not very accurate. However, one of the devices still boasts. The clock, made in the 20th century for the town hall of Copenhagen, has a huge mechanism of 14,000 elements. Due to their complex design, as well as rather slow functionality, their measurement errors are a second for every 600 years.
