The Modern Age of Timekeeping
In the modern world, timekeeping has become much more precise, thanks to atomic clocks. These clocks measure time based on the vibrations of atoms, specifically cesium or rubidium, and are accurate to within billionths of a second. Atomic clocks are essential for systems like GPS and global communication, where precise time synchronization is critical. Today, many of us carry smartwatches or rely on smartphones to keep track of time, but these devices still depend on the principles of timekeeping that have evolved over thousands of years.
