Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical ...

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 ...

Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block, the ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

In a not-so-common breakthrough towards redefining the basic unit of time, a Chinese research team at the University of Science and Technology has unveiled a groundbreaking optical clock that provides ...

The clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say. A new atomic clock is one of the world’s best timekeepers, ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

Markus Lutz is CTO and Founder of SiTime Corporation. He is a MEMS expert, a prolific entrepreneur and inventor who holds over 100 patents. Timekeeping might be the unsung hero of human ingenuity. The ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

In an era when millions of Americans are chained to computers, handcuffed to BlackBerrys and plugged into iPods, something as simple as knowing the current time should be easy. But here’s the snag: ...
