Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...

Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

“It seemed the right time on the page ... it suited my eye.” That’s how Martyl Langsorf responded when asked why the hands of the Doomsday Clock were placed at seven minutes to midnight back in 1947.

CC0 Usage Conditions ApplyClick for more information. Harold Lyons was a physicist whose primary interest was in atomic frequency standards and atomic clocks. The collection documents Lyons and his ...

An ultra-precise laser synchronized to one of the world’s most precise clocks has been used to excite rapid nuclear oscillations — promising a timekeeper that could help to tackle fundamental ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

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 ...
