As anticipation builds for the longer days that follow this weekend’s switch to daylight savings time, the moment seemed ideal to turn to one of the nation’s leading circadian-rhythms researchers, UC ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks work, ...
