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.

A highly precise measurement of a physical constant known as the fine-structure constant provides a stringent test of the standard model of particle physics, and sets strong limits on the ...

In physics, the Fine Structure Constant is one the strangest numbers.

In quantum electrodynamics, it is the coupling constant that determines the strength of interactions between electrons and photons. What remains undisputed, however, is its centrality to physics, and ...

These subshells are the fine structure the constant refers to. Each subshell is spaced a bit apart from the adjacent subshells in the same main shell. How far apart?

According to everything we know about the physics of the universe (and good sportsmanship), it should be: Physicists don't call it the fine structure constant for nothing.

1/137, known as the fine-structure constant (α), is one of the most mysterious numbers in all of physics. To most, it may seem like just a fraction, but this number quietly governs the rules that ...

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, by contrast, has no dimensions or units. It’s a pure number that shapes the universe to an astonishing degree — “a magic number that comes to us with no understanding,” as ...
