The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

When J. Robert Oppenheimer and crew set to work at Los Alamos, they were largely focused on the destructive potential of the atom. By the time they were finished, they had succeeded in making the most ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

The goal of the Defense Advanced Research Projects Agency’s (DARPA’s) Chip-Scale Atomic Clock (CSAC) program is to provide warfighters with enhanced radio communications and jam-resistant navigation ...

WASHINGTON — 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 ...

The timekeeping device is made with atomic nuclei of thorium, although it is not yet more precise than standard atomic clocks. Reading time 2 minutes Meet the “nuclear” clock: a device that marks the ...

"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, ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even rewrite ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...
