New Strontium Atomic Clock sets new world records in term of precision up to 5 billion years

 New Strontium Atomic Clock
The Atomic Clock model of National Institute of Standards and Technology works with Strontium. Many of the current technological devices use Coordinated Universal Time (UTC); which is one of the international unit of measure made reliable by atomic clocks around the world. But a revolution will perhaps take place in this area: a new type of clock that will pass the time; for a long time, even until the end of our time. JILA laboratory at the University Of Boulder, Colorado, has a unique design of its kind of Atomic clock.

It looks little bit strange but this clock is obviously not like the others. It is a new model of atomic clock, giving the most accurate time in the world! This clock was unveiled in the journal Nature and operates like other atomic clocks, with a jet of atoms, moving from an excited state to another (by stimulated by a laser), gives a frequency electromagnetism frequency which will define a second reference. This can be seconds, subsequently calculated the minutes and hours.

The set of more than 300 atomic clocks scattered on Earth and in orbit around the Earth to form a network giving the International Atomic Time, which is a yardstick used to disseminate the Coordinated Universal Time (UTC), itself is used to satellites, GPS, watches and other computers and everything in the planet. More than 300 atomic clocks in the world but the Boulder the new atomic clock differs here. Boulder first uses a material which is not listed as used in the process of other atomic clocks. This is a clock Strontium, while other atomic clocks using cesium.

It promises a still life and calculates the exact time upto5 billion years! And yet, the results are there and can be further refined, as explained by Jun Ye, the Department Head Search Clock affiliated with National Institute of Standards and Technology U.S. He told that they ready have plans to push performance even further progress in their clocks in the next five to ten years, he promised.

And if 5 billion years may seem sufficient precision for the common man in the search, whether the infinitely large or small, every second counts, and the technology in this field will be reliable, the more it will achieve positive results. By comparison, the atomic clock of the Observatory of Paris, which is one of the most successful operating Cesium clocks, could give the second with precision about 300,000 million years. Now, officials and the new NIST atomic clock model will apply to ask to accept the strontium in addition to or in place of cesium and it is only a matter of time!
