One of the most exciting prospects in physics has been discovering that fundamental constants are not actually constant at all. When I first started writing, physicists and astronomers were just ...

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 ...

A team in Paris has made the most precise measurement yet of the fine-structure constant, killing hopes for a new force of nature. As fundamental constants go, the speed of light, c, enjoys all the ...
