A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the ...

Scientists in Germany have unveiled that the world’s most precise mobile atomic clock is so accurate that it will be off by ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to ...

A millimeter might not seem like much. But even a distance that small can alter the flow of time. “This is fantastic,” says theoretical physicist Marianna Safronova of the University of Delaware in ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.

"Atomic clocks bring cosmology and astrophysics down to Earth, enabling searches for ultra-light particles that could explain dark matter in a laboratory." When you purchase through links on our site, ...

Even if you’re one of the most precise physicists on the planet — as University of Delaware Professor Marianna Safronova is — you still will need collaborators whose skills complement your own and ...
