A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...

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, ...

In physics, the Fine Structure Constant is one the strangest numbers. The Fine Structure Constant is one the strangest numbers in all of physics. It’s the job of physicists to worry about numbers, but ...

One over 137 - this is one of the most important numbers in physics. It is the approximate value of the so-called fine structure constant - a physical quantity that is of outstanding importance in ...

The fine structure constant is one of the most important natural constants of all. At TU Wien, a remarkable way of measuring it has been found—it shows up as a rotation angle. One over 137: This is ...

Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...
