Here Dyson elaborates on his ground-breaking articles, "The radiation theories of Tomonaga, Schwinger and Feynman" and "The S matrix in quantum electrodynamics," working through the Dirac theory, scattering problems and born approximation, field theory, examples of quantized field theories, free particle scattering problems, the general theory of free particle scattering, and scattering by a static potential with a comparison to experimental results.
