Goals
 Obtain an expression for the amplitude of oscillation of the quantum field oscillators as a function of radius from a single stationary electron, assuming there is nothing else in the universe.
 Prove the uniqueness of the QED Lagrangian.
 Explain how representation theory creates a physical difference between singlet and triplet atomic states.
 Explain the non electromagneticlike terms in the linearized gravitational force law.
 Explain why the YukawaWick argument uses E=mc^2 instead of the relativistic form.
 Understand Ohanian's "What is Spin?" paper.
 Explain why even spin mediators are always attractive.
 Derive the gauge transformation rule for fields from the concept of gauge transformations in EM.
 Prove the theorem about the metric and fully antisymmetric tensor being the only relativistic invariant tensors.
Other Quips
 Spin tells you the number of indices
 Anything that can happen does happen (list some examples)
 There is no tree level flavorchanging neutral current (experimental fact, but is there a theoretical reason?)
