Subject: Static GK (General Knowledge)

Book: General Time Knowledge

Atomic clocks measure the resonant frequency of atoms, particularly cesium or rubidium, providing unparalleled accuracy in keeping time. These clocks serve as the basis for Coordinated Universal Time (UTC), ensuring that global communications, navigation systems, and scientific experiments remain in precise sync. Many researchers and tech enthusiasts look up atomic clocks to grasp how a few nanoseconds of drift can impact GPS functionality or financial market timestamps. By understanding atomic clocks, one appreciates the sophisticated infrastructure underlying our modern conception of time.
