Re: Hydrogen in Relativistic QM

That's a good question. Relativistic QED has a trouble in describing
the bound state of the hydrogen atom. This trouble is explained by
Weinberg in the beginning of chapter 14 of his "The quantum theory of
fields" vol. 1. All we can do in QED is to calculate the S-matrix.
Nonsense. Almost everything of interest can be calculated in QED.
The first and still the most conspicuous nontrivial calculation
in QED was that of the Lamb shift, which is a statement about a
bound state of hydrogen. One can also calculate the spectrum
of positronium to high accuracy.
It is time you give up your narrow views about QED!
