In the last 3 years I have given several talks on relativistic equations for nuclear physics, and on relativistic effects in few nucleon systems1. In preparing for these talks, and in responding to the discussion which followed them, my thinking about relativistic equations and relativistic effects has gradually evolved. I want to begin this talk by focusing on several issues which naturally arise when discussing this subject, and then turn to a brief discussion of relativistic three nucleon equations. The latter topic has not been reviewed recently, and is particularly of current interest because of the beautiful form factor measurements of the 3He — 3H system recently completed at Saclay2 and Bates3, and the accompanying speculation that relativistic effects are important for understanding the three-nucleon system.
