That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum ...

Previously, [Vinnie] had been stopping the clock every evening, and hoped he would remember to start the pendulum in motion 12 hours later. This was a chore, so he decided to automate the process.

Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures.

A recent breakthrough has paved the way for timekeeping even more precise than the measurements performed by atomic clocks.

The timekeeping device is made with atomic nuclei of thorium, although it is not yet more precise than standard atomic clocks ...

Questing for a truly constant “tick,” scientists have zoomed in on the atomic world, where the minuscule scales and ...

Atomic clocks have been used for decades – but now, even greater precision has become possible: presenting the world's first ...

Harnessing quantum principles, atomic clocks achieve extraordinary timekeeping accuracy, transforming navigation, ...

The clocks and watches featured here are just a sampling from ... Museum of American History Shelf Calendar Clock National Museum of American History Galileo Pendulum Clock Model, Replica National ...

The complexity of the system – and its capacity to model and solve computational problems –  increases with each additional coupled oscillator. “The interaction is where all the magic is,” Bullo said.

The Foucault pendulum which was displayed for many years in the Smithsonian's National Museum of American History was removed in late 1998 to make room for the Star-Spangled Banner Preservation ...

Atomic clocks are considered to be the most accurate timekeeping instruments available today. But now a new technology has been developed that promises even greater accuracy: Atomic clocks could be a ...
