I have read this very interesting discussion about fine structure
constant, QED etc., on FOM, in February and March, but just now I have a
leisure to join the discussion.
Namely, I have a remark that as far as fine structure constant is
concerned, a theory, explaining the value of this constant, i.e. what is
the nature of the electric charge of electron, was constructed by Andrzej
Staruszkiewicz (Marian Smoluchowski Institute of Physics, Jagiellonian
University, Krakow, Poland).
I give here the references to several his papers, devoted his theory:
1. Ann. Phys. (N.Y.) 190, 354 (1989).
2. Acta Phys. Pol. B 26 (7), 1275 (1995).
3. BANACH CENTER PUBLICATIONS, VOLUME 41, 257 (1997), INSTITUTE OF
MATHEMATICS POLISH ACADEMY OF SCIENCES, WARSZAWA 1997.
4. Tr. J. of Physics 23, 847 - 849 (1999) - also published in "New
Developments of Quantum Field Theory", NATO Science Series: B: Vol. 366,
179 (2002), Editors: Poul Henrik Damgaard and Jerzy Jurkiewicz, Plenum
Press, New York.
5. Acta Phys. Pol. B 33(8), 2041 (2002).
6. Found. Phys., 32 (12), 1863 (2002).
This my remark refers somewhat also to a question of Jay Sulzberger,
cit. "Is there a consistent theory of QED, consistent to the usual
standard of professors of mathematics?".

and even the alpha^6 term is currently incomplete (and gives a result of
unknown accuracy), as for tractability only the contributions deemed most
relevant are included.

point to far less, but point to what is common practice in reporting high
precision physics calculations.
