As the world prepares to welcome the first GPS watch, researchers from the Georgia Institute of Technology (Georgia Tech) are developing the model for a nuclear clock which would get its extreme accuracy from the core of a single thorium ion. There are many ecological watches powered by the sun on the market, thenuclear clock priceless.
L'nuclear clock it could be useful for certain forms of secure communication and could provide numerous stimuli for the study of fundamental theories of physics. Identify the model for the development ofnuclear clock, you will get a device that could be up to 100 times more accurate than current atomic clocks that currently use the base for the GPS global positioning system.
The study was published in the scientific journal "Physical Reviw Letters". Alex Kuzmic, Professor of Physics at Georgia Tech and coator of the study, says that "if you give people a better watch, people will use it!". In fact, there are many field applications fornuclear clock. For most uses, the athymic clocks currently popular, they can be approximately accurate, but for a nuclare clock other realities will open up.
The evolution of the clock: grandfather clock, quartz clock, atomic clock and the futuristic nuclear clock.
Early clocks used a swinging pendulum, pendulum swings were needed to keep track of time. In modern watches, quartz crystals provide high-frequency oscillations that act like a tuning fork replacing the old pendulum. Atomic clocks are more accurate because they exploit the oscillations of electrons in atoms, however these electrons can be affected by magnetic and electric fields, so that an atomic clock in the life of the universe could lose about four seconds.

Neutrons are much heavier than electrons, dense in the atomic nucleus, they are less sensitive to magnetic and electrical perturbations. In other words, they are more stable than electrons. This is why a nuclear clock it should be much less influenced by environmental factors, therefore more accurate than its atomic cousin.
Currently, the model is still under study, but there is no doubt: the former nuclear clocks could be powered precisely bysolar power in what can be defined as a perfect combination of innovation and green technology.
