Feynman's approach to precision QED calculations, see his book "Quantum Electrodynamics", was shown(?) to be equivalent to the method of quantum fields. Both methods get the right the get the right answers to some problems.
What quantum problems does Feynman's method (there is a name for that I guess) not work or work as well when compared to the method of Quantum Fields?
Thanks for any help!
The book, much of which can be read (edit, some of which can be read),
