Cool. I didn't know there was a formula for the fine structure constant.
Now I find myself wondering if there is any theoretica justification for
that formula, or whether de Vries just kept adjusting the formula unti
it came out approoximately correct.
Especially because the Wikipedia article
cites experimental evidence that the find structure constant has changed
over the past ten billion years or so.
Of course the evidence could be wrong.
