High-precision laser spectroscopy measurements on the thorium-229 nucleus could reveal new physics, say TU Wien physicists ...

Thorium atomic nuclei can be used for very specific precision measurements. This had been suspected for decades, and the search for suitable atomic nucleus states had been ongoing worldwide. In 2024, ...

Even on a black hole’s turf, an essential constant of nature holds steady. According to standard physics, the fine-structure constant, which governs interactions of electrically charged particles, is ...

Electronics is really an applied branch of physics, so it isn’t surprising that if you are serious about your electronics, you probably know a little physics, too. If you’ve ever heard the term “fine ...

Physicists have made the most accurate measurement to date of the fine-structure constant, alpha -- the dimensionless number that is a measure of the strength of the electromagnetic force. The new ...
