Optical Atomic Clocks Poised to Redefine How the World Measures a Second
Revolution in Timekeeping: A New Standard on the Horizon Time keeps ticking, but the method we use to measure each second is about to undergo a fundamental shift. Optical atomic clocks, which use optical frequencies rather than microwave transitions, promise unprecedented precision and stability. This leap could recalibrate global timekeeping systems and support advances across…

Optical Atomic Clocks Redefining the Second Measurement
Rewriting a Fundamental Benchmark: The Second The very fabric of timekeeping is at a potential turning point. Optical atomic clocks, leveraging ultra-stable light frequencies, are approaching a level of precision that could redefine how we measure one second. In collaborative efforts between the University of Adelaide and the National Institute of Standards and Technology (NIST),…
