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 10 times its normal value in the material, giving a peek into what physics in an alternate universe could look like.

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating ...

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 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.

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 so-called fine-structure constant may have different values in different parts of the universe. ... Astronomy Unknown physics may help dark energy act as 'antigravity' throughout the universe.

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 ...

The fine-structure constant α is a composite of several physical quantities (including e, the charge on an electron, and c, the speed of light) that, together, characterize the strength of the ...
