Atomic clock

The atomic clock for more exact measurement of time

Today the mankind applies the atomic clock to counting of seconds; however the French scientists developed the alternative nuclear mechanism which promises more exact measurements of time. Optical mesh hours have a course error in only 1 second for 300 million years. As well as usual watches which rely on a pendulum for measurement of intervals of time, a new watch apply nuclear vibrations. In the majority of a modern atomic clock it is a question of fluctuations of atoms of cesium which throw out special microwaves with accurately set intervals. The new system of the atomic clock uses very short beams of light bringing into the raised condition atoms of strontium. By the words of Professor Jerome Lodewyck from the Parisian observatory in their watches are applied laser beams. These beams oscillate much quicker than microwave radiation; therefore they can divide them into smaller intervals to measure time more precisely.

Among other things, researchers say that novelties also are surprisingly stable, keeping the provision of chronometers very long. For example, if your watches go one day on a second quicker, and another a second more slowly, they aren’t stable. However all of them equally offer the good accuracy if time show finally truly. The atomic clock offers not only three times higher precision, but also stability.
