Atomic clocks are an order of magnitude more precise than even the best temperature controlled crystal oscillators. Bill Hammack has a great video describing the operation of a cesium beam oscillator.

So steady are these oscillations that atomic clocks keep better time than the spinning earth itself The "pendulums" which regulate them are the vibrating parts of atoms or molecules.

Clock timing and data transmission are inextricably ... Silicon-based timing solutions can offer performance advantages over quartz oscillators. We spoke to Piyush Sevilla, EVP of Marketing ...

Plus, it allows one of the microcomb’s frequencies to be locked to a laser, which is then locked to the atomic clock’s oscillation. This creates a stable reference that can be used for precise ...

Atomic clocks count the oscillations of vibrating atoms that switch between two energy states with very precise frequency. Most atomic clocks use microwave frequencies to induce these energy ...

One long-standing model of the rodent circadian clock describes it as a complex pacemaker consisting of two mutually coupled oscillators differentially affected by light, with one synchronized to ...

Atomic clocks count the oscillations of vibrating atoms that switch between two energy states with very precise frequency. Most atomic clocks use microwave frequencies to induce these energy ...

An optical lattice clock is a type of atomic clock that uses the frequency of atomic oscillation to measure advancement of time. A myriad of atoms are confined inside Katori's specially designed ...
