“Clarification? In his description of the Pais effect here, it seems #Pais is trying to say that through dimensional #analysis of classical means (#Maxwell via #Heaviside + harmonic osc.) one can arrive in conditions that exceed the #Schwinger limit via of some kind of "compounding effect" through rapid acceleration of charges.” — XxxThePsyCheMisTxxX

Abstract: Having developed the diagrammatics in detail, we now address the problem of explicitly computing the diagrams. The study is facilitated by introducing Feynman and Schwinger parametrization of the loop integrands. We argue that generically loop diagrams are fraught with UV divergences coming from large values of the loop momenta. Typically the diverging contribution comes from a “region of coincidence” where all the vertices associated to the loop coincide in position space. Next we introduce a key concept called superficial degree of divergence. We explain what is superficial about it and then state and outline the proof of Weinberg’s theorem associated with it. This allows us to explore the pattern in which divergences appear for power law potentials depending on the mass dimension of the coupling.

...and because I am the ultimate #Schwinger #groupie I taught myself how to write with the left hand. Of course, one of the differences is that Schwinger did it with both hands *at the same time*

Schwinger taught physics with both hands
