The fine-structure constant α is of dimension 1 (i.e., it is simply a number)

and very nearly equal to 1/137. It is the "coupling constant" or measure of

the strength of the electromagnetic force that governs how electrically charged

elementary particles (e.g., electron, muon) and light (photons) interact.
