For three-quarters of a century, scientists have used nature’s perfect timekeepers — atoms — to build the best clocks the world has ever seen. Atomic clocks have revolutionized how we tell time. These astoundingly accurate devices touch the lives of every person on Earth and keep us in sync no matter where we are. They make possible world-changing technologies such as GPS and help scientists explore some of the universe’s deepest mysteries.
Harnessing atomic time is one of humanity’s most beautiful and awe-inspiring achievements.
