(The same question has also been asked of the fine structure constant.)

The fine structure constant is fixed to the strength of the electromagnetic force.

He set out alleged mathematical reasons why the reciprocal of the fine structure constant had to be exactly 136.

The Killing form is the simplest 2-tensor that can be formed from the structure constants.

Lightspeed is part of the ratio known as the fine structure constant.

She said, "Case, the fine structure constant is a measure of the strength of an electric or magnetic force."

The inverse lifetime to lowest order in the fine structure constant is given by:

We then have where f is the structure constants of octonion multiplication.

Here use is made of the relation for the fine structure constant:

So if the fine structure constant was different, the light will have a different color from that emitted by the same elements on Earth.
