World-first nuclear clock prototype could outperform atomic clocks

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

A New Kind of Atomic Clock Could Redefine the Second

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future ...

This New Atomic Clock Is So Precise It Won’t Lose a Second for 140 Million Years

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick — not ...

A Chip that Keeps Time (Almost) Like an Atomic Clock

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

New atomic fountain clock joins elite group that keeps the world on time

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

New optical atomic clock is 1,000x more accurate than today's standard

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

World's most accurate atomic clock off by 1 second every 30 billion years

Scientists have developed the most precise and accurate atomic clock to date – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only improve ...

Redefining the second: Optical atomic clock achieves record accuracy in comparison measurement

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

True or false: The first alarm clock could only ring once?

They say, 'Necessity is the mother of invention,' and in many ways, that's true. There are many motivations to invent, some ...
