TED-Ed: How does your smartphone know your location? - Wilton L. Virgo

The video explains how smartphones determine location using GPS satellites and atomic clocks. It highlights the importance of precise timekeeping, achieved through atomic clocks powered by quantum mechanics. These clocks use the consistent frequency of caesium-133 atoms to provide accurate time readings. The video also covers how GPS triangulation and Einstein's theory of relativity help pinpoint exact locations on Earth.
