I've been trying to figure out this paper by W. Smilga: Spin foams, causal links, and geometry-induced interactions(adsbygoogle = window.adsbygoogle || []).push({});

I don't have the knowledge and background to be able to determine whether his derivation of an estimate to the fine structure constant is interesting, or just a trick.

I am referring toXIV: Estimate of the Coupling Constant. Through some mathematics I don't understand yet, he gets a value for the fine structure constant of 1/137.03608245, which agrees to the real value "in five parts in ten-million".

What is the consensus of the physics community on this? Is it just numerology?
