In this episode of Simply Science, we take a deep dive into the world of atomic clocks—the most precise timekeeping devices ever invented. Although this episode begins with a request to explain atomic clocks in simple terms, we use it as a starting point for an educational journey into the fascinating science that powers these ultra-accurate timepieces.

We’ll explore how atomic clocks work, why they are so important for technologies like GPS and telecommunications, and how they have revolutionized our ability to measure time with unparalleled precision. We also delve into the history of timekeeping, from early mechanical clocks to the atomic age, and explain the physics behind how atoms, lasers, and microwaves come together to keep time ticking perfectly. Tune in to learn about the incredible technology behind the devices that help synchronize the world down to the nanosecond!
