NUCLEAR POWER HOUR

For years, the atomic clock is considered as the most accurate device to show time. Clock that uses the size of sub atomic particles that move several times per second is almost never make mistakes.

However, now the atomic clock reliability as the most accurate clock in the world will likely be displaced by the hour because of a natural nuclear, nuclear is more resistant to interference from the outside compared to the atom and create the appearance of potential errors is lower.

Quoted from Science Daily, 10 November 2011, although the atomic clock to measure a certain number of vibrations per second, outside forces such as magnetic and electric fields can affect the electrons used in atomic clocks. This could potentially lead to errors.

On the other hand, the particles used in the nuclear clock that measures the vibration and also determines the time, can be triggered using low-energy ultraviolet light. This resulted in the influence of factors external to the system that is in the lower atomic clocks.

With this method, Corey Campbell and his fellow researchers from the Georgia Institute of Technology, Atlanta, United States has made a scheme that uses a laser to control the spatial orientation of the orbits of electrons in the atom.

Researchers claim, the nuclear clock which has a thorium nucleus is controlled in this way will only miss up to one second over a period of 200 billion a year.

However, before the nuclear clock can be realized, researchers must identify the exact frequency of light needed to trigger the thorium nucleus.
