Abstract
The various procedures for renormalization i.e. "abnormalization" in agreement with Feynman, suggest that current physics has serious problems with numbers, especially zero and infinity. This problem can be solved by the discovery of the relationship between two-element numbers – complex, parabolic (dual), hyperbolic numbers – with a so-called quality infinity.
