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, ...

As fundamental constants go, the speed of light, c, enjoys all the fame. Yet c’s numerical value says nothing about nature; it differs depending on whether it’s measured in meters per second or miles ...

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 ...

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

A new measurement of the fine-structure constant is three times more accurate than before. The constant helps glue together "coarse" and "fine" measurement of particles. The new measurement bests a ...

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 ...
