What are Feynman Diagrams and how do they help explain Quantum Electrodynamics?

[QUOTE="dextercioby, post: 6213400, member: 1064"] It IS the field theory but with special fields for the classical pointlike particles and special (complicated but to me extremely beautiful) mathematical features. So from a high-school perspective: small magnets and electrons presented as points of no dimension and mass 9.10^-31 Kg and charge -10^-19 C are replaced by abstract (fictive if you want) "fields" of the same type of field with which the electric and magnetic fields generated by these classical objects are replaced. QED is a quantum field theory. Stress on Quantum, and stress on "field", but this field is not something you can directly measure. [/QUOTE]
