What does it really mean to integrate over all possible fields in the Path integral formulation of quantum field theory,and how does such a formalism goes out to decribe(adsbygoogle = window.adsbygoogle || []).push({});

field quanta????

Another question is

im new to Quantum field theory

i was wondering whether i should stick to the old second quantization approach of QFT or would it be better to directly jump to path integral method of doing QFT
