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 ...
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, ...
In sports and in cosmology, the rules of the game aren't supposed to change as you go along. Athletes call this playing fair. Cosmologists call it the cosmological principle, and it means that the ...
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 ...
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 ...
Angle of rotation: A light source (left) sends a beam of light through a topological insulator with an intrinsic magnetic field (centre), changing the direction of polarization by an angle that is ...
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, ...
Legislators change laws from time to time, but Mother Nature's laws are eternal -- or so it has seemed. Now, though, scientists are debating clues that suggest the laws of physics change over time.
The core element of the experiment: a crystal containing thorium atoms. (Courtesy: TU Wien) New high-precision laser spectroscopy measurements on thorium-229 nuclei could shed more light on the fine ...
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 ...
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 ...
