The fine structure constant, denoted α, is a dimensionless number with a physical interpretation that has evolved alongside physicists’ understanding of electromagnetism. When Arnold Sommerfeld ...

The fine structure constant is a combination of four other fundamental constants: the speed of light, the charge on the electron, Planck’s constant, and the permittivity of free space.

This article was originally published with the title “ Physicists Achieve Best Ever Measurement of Fine-Structure Constant ” in SA Space & Physics Vol. 4 No. 1 (February 2021) doi:10.1038 ...

The fine-structure constant, about 1/137, is a measure of the strength of the electromagnetic interaction and quantifies how electrons bind within atoms and molecules. It is a dimensionless number, ...

The fine-structure constant is 10 times its normal value in the material, giving a peek into what physics in an alternate universe could look like.

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. General Physics ...

This is my favorite expression for the Fine-Structure Constant, there are a handful of others. But as an EE my bias is showing. Let’s see if this will post intact in WP Jetpack, even without pre.

The physics of the universe appear to be fine-tuned for life. ... The researchers found that in the northern sky, thefine-structure constant gets smaller with increasing distance, ...

One of physics’ most fundamental constants just got a little more constant. Physicists have placed the strictest limit yet on how much the fine structure constant — which determines how ...
