High Energy Quantumelectrodynamics II
Quantumelectrodynamics is at present the only example of a complete relativistic quantum theory which is known to be relevant to physics. The rules for calculation based upon Feynman diagrams give one an unambiguous method to compare the theory with observation. The agreement so far has been without exception. One likes to believe that there is a basis for the calculational rules in quantum field theory. However, so far the attempt to produce such a field theory either has led to a case in which divergences occured if the perturbation rules were applied universally or to rather complicated “renormalized” versions of the theory which try to circumvent the divergences by formulating the calculational rules in terms of renormalized operators at the expense of an explicit expression for the Hamiltonian in terms of these operators. Usually attempts to modify the theory have only led to situations where the modifications produced more new deseases than the few cured.
