Each element of a Feynman diagram represents a different term in our calculation. | + | Feynman diagrams are a pictorial way to keep track of terms in [[theories:quantum_field_theory:canonical|quantum field theory]] calculations.

| The thing is that we can't calculate things in quantum field theory exactly, but only using a perturbation approach (Taylor series). The first term in this approximation to the correct result yields the biggest contribution and thus is the most important part. | The thing is that we can't calculate things in quantum field theory exactly, but only using a perturbation approach (Taylor series).
