National Institute for Standards and Technology researchers remain at the spearhead of atomic clocks design by creating what is known to be the most accurate time keeping device in the world.

Some of the first atomic clocks were actually masers, commonly known as microwave lasers, that had additional equipments attached to them.

For centuries, navigation by ships has depended on clocks. Sailors have depended on latitude and longitude measurements and although altitude is fairly easy to determine through celestial navigation, the measurement of longitude requires accurate measurement of time. This need was a major motivation for the developm... |
