Indeed, 51 years later, this is still a fine paper that has been a basis for all (g-2) higher loop calculations since. No problem with any Feynman graph.

Then I would meet C. N. Yang again, and he would point that in Mills' and his *other* paper they showed that ...

So it went. Every time.

I would explain that Kinoshita and I worked in the Feynman parametric representation, where all internal 4-momenta are integrated out, and, as I explained in cns.gatech.edu/~predrag//pa..., each graph was a circuit obeying Kirchhoff's laws, and that there is *no* "routing of momenta" puzzle.

Turns out he and Mills wrote *another* paper, that one on the evaluation of higher loop Feynman integrals, where -if I remember this even approximately- they found that routing of 4-momenta in a 7-loop graph cannot be made consistent. He would bring that up every time I met him.

I think about the title of this report on a weekly basis stanleycenter.org/publications...

I like Swiss train station clock style Swiss watch.
