Nastase’s approach to teaching QFT generally follows a logical trajectory designed to build confidence before tackling the "monsters" of the field, such as renormalization and non-Abelian gauge theories. 1. The Transition from Particles to Fields

The journey begins by explaining why we need fields in the first place. Nastase emphasizes the limitations of standard quantum mechanics—specifically its inability to handle particle creation and annihilation. By treating particles as excitations of underlying fields, the framework becomes capable of describing the subatomic world. 2. Canonical Quantization vs. Path Integrals

This is where Nastase’s clarity shines, showing how the Feynman propagator and correlation functions emerge naturally from functional integration. 3. Interacting Fields and Feynman Diagrams
