Atomic clocks are essential tools in modern life, relying on hundreds of satellites orbiting the Earth to provide precise timing for GPS location, internet connectivity, stock trading, and space navigation. But have you ever wondered how these clocks work?
To answer this question, hosts Emily Kwong and Regina G. Barber explored the inner workings of atomic clocks during a recent episode of NPR’s Short Wave show. They delved into what makes a clock precise and discussed ways to improve its accuracy.
According to experts, precision in timing is achieved by using tiny atoms as the basis for measurement. These atoms vibrate at specific frequencies when exposed to light, allowing scientists to synchronize clocks across vast distances. By studying these atomic vibrations, researchers can create more accurate timekeeping devices.
The OASIC project, a collaboration with NASA, has made significant advancements in atomic clock technology. The project’s findings are outlined in Dava Sobel’s book “Longitude,” which explores the long-standing problem of longitude measurement and its connection to timekeeping.
