Ultra-precise Atomic clocks

Atoms cooled to very low temperatures with laser light forms the basis for the most precise measurements ever made in science.
The atomic clock is so precise that it only loses/gains less than a second in 3 billion years. The development of this type of atomic clock is vital for the future technological developments in fields such as communication and navigation in space.
