transition amplitude are too hard to calculate from the theory, except in infinite time limits
those limits are the entries of the S-matrix
typical way to compute S-matrix entries is using correlation functions and Ward identity

probability amplitude from initial states to final states
Feynman diagram is a tool to compute the probability amplitudes.
- transition amplitude
- scattering amplitude
  - computation of S-matrix (S = Scattering)
  - cross section
these are important because they are physically measurable quantity
- similar to correlation functions in Conformal Field Theory
- look at correlation functions and Ward identity page
