Book excerpt: In these lectures, I will review the theoretical concepts needed to understand the goals and implications of experiments in this new era of weak interactions. I will explain how to compute the most important order-[alpha] radiative corrections to weak interaction processes and discuss the physical implications of these correction terms. I hope that this discussion will be useful to those -- experimentalists and theorists -- who will try to interpret the new data that we will soon receive. This paper is organized as follows: I will review the structure of the standard weak interaction model at zeroth order. I will discuss the measurement of the Z° boson mass in ee− annihilation. This measurement is affected by radiative correction to the form of the Z° resonance, and so I will review the theory of the resonance line shape. I will briefly review the modifications of the properties of the Z° which would be produced by additional neutral gauge bosons. I will review the theory of the renormalization of weak interaction parameters such as sin2 [theta]{sub {omega}}, concentrating especially on the contributions of the top quark and other heavy, undiscovered particles.
