Most pedagogical texts on QFT are geared toward budding professional physicists, however, whereas mathematical accounts are abstract and difficult to relate to the physics. We explain in simple cases how this method can be used to re-parameterize a theory, and how the physicists use it to tame the diverging integrals by having “the counter terms cancel the divergences”.
