Editing Fine-structure constant (section)

For historical reasons, {{mvar|α}} is known as the fine structure constant. Unfortunately, this name conveys a false impression. We have seen that the charge of an electron is not strictly constant but varies with distance because of quantum effects; hence {{mvar|α}} must be regarded as a variable, too. The value 1/137 is the asymptotic value of {{mvar|α}} shown in Fig. 1.5a.<ref>The asymptotic value of {{mvar|α}} ''for larger observation distances'', is intended here. Caption: Fig 1.5.

The mystery about {{mvar|α}} is actually a double mystery: The first mystery – the origin of its numerical value {{mvar|α}} ≈ 1/137 – has been recognized and discussed for decades. The second mystery – the range of its domain – is generally unrecognized. | M.H. MacGregor (2007)<ref>
