How do people around the world keep time together? They use atomic clocks. These remarkable devices tap into frequencies hidden in the hearts of atoms to produce astoundingly stable, accurate ticks of time – far better than any other kind of clock. This animation explains why we use atoms to keep time and how they keep us all on the beat. | National Institute of Standards and Technology (NIST)

NIST-F4 isn’t just a clock — it’s the culmination of decades of scientific ingenuity, engineering breakthroughs, and an unwavering pursuit of precision. In this video, we explore the creation of NIST-F4, the United States’ latest primary frequency standard, and how it redefines what it means to measure time with atomic accuracy. From unexpected flaws to groundbreaking redesigns, this is the story of how one of the most precise timekeeping instruments ever built came to be — and why it’s crucial
