An atomic clock is a timekeeping device that measures time based on the vibrations or transitions of atomsβ€”usually cesium or rubidium. Unlike mechanical or quartz clocks, which rely on moving parts or crystals, atomic clocks use the natural oscillations of atoms as their frequency standard. This makes them the most accurate clocks ever developed, capable of maintaining time to within a few billionths of a second per day. Atomic clocks are essential for applications where extreme precision is required, such as GPS navigation, telecommunications, space exploration, scientific experiments, and synchronizing global networks.
