Four tutorial lectures were delivered to provide an introduction to high energy positron-electron annihilation physics, and to serve as a foundation for more advanced lectures. The first lecture discusses three subjects: the parameters of e{sup +}e{sup -} storage rings that are directly relevant to experiments, the physics of e{sup +}e{sup -} one-photon exchange as illustrated by the reaction e{sup +}e{sup -} .-->. .mu.{sup +}.mu.{sup -}, and the naive quark model for the reaction e{sup +}e{sup -} .-->. hadrons. The second lecture is devoted to heavy leptons: the status of the tau lepton, and the status of the search for heavier leptons. The third lecture discusses the nonrelativistic quantum mechanics of heavy quark-antiquark systems - the psi/J particle family and the T particle family. As e{sup +}e{sup -} colliding beams machines attain very high energy, E{sub c.m.} greater than or equal to 50 GeV, e{sup +}e{sup -} annihilation will occur through the weak interactions as well as through the electromagnetic interaction; this will allow the study of the weak interactions and the study of any new particle related to, or produced through, the weak interactions. Lecture 4 discusses this physics at an energy corresponding to the mass of the Z{sup 0} intermediate boson, and then discusses the physics at yet higher energy. The lecture concludes with a description of the capabilities and limitations of the e{sup +}e{sup -} colliding beams machines needed to attain this very high energy - both storage rings and colliding linear accelerators.
