Atomic Clocks: The clocks that keep the world on time

A continuation of my last video on how quartz clocks function. Atomic clocks are used around the world work together to create the time standard we all live by. The atomic clock uses an ingenious process that relies on the very stable and reliable quantum properties of electrons in specific atoms to keep crazy accurate time. Several diverse things you might not expect, like credit cards, encrypted phone calls, and GPS would not be possible without atomic clocks.
