I am also pleased that Oxford has given, “(unlimited) permission to use the material of the first edition in the second one . . . ” The original motivation for writing this book was two-fold. First, I wanted to lay out the intellectual foundation for the construction of CEBAF, the Continuous Electron Beam Accelerator Facility, of which I was Scientific Director in its initial phase from 1986-1992. Second, I wanted to help bring young people to the point where they could make their own original contributions on the scientific frontiers of nuclear and hadronic physics. CEBAF, now TJNAF (the Thomas Jefferson National Accelerator Facility), is currently a functioning laboratory, continually producing important scientific results. The need to “sell” it no longer exists. Furthermore, in 2001 the author published a book with Cambridge University Press entitled Electron Scattering for Nuclear and Nucleon Structure, which focuses on the foundation of this field and eliminates the need for a disproportionate emphasis on this topic. Correspondingly, the chapters on CEBAF’s role a t the end of the various parts in the first edition of this book have been eliminated. In Part 1, a chapter on the many-particle shell model now replaces it. One of the major advances in nuclear theory in the past decade has been the placing of model hadronic field theories of the nuclear many-body system (quantum hadrodynamics, or QHD) on a firm theoretical foundation through the implementation of effective field theory for quantum chromodynamics (QCD); furthermore, relativistic mean field theory now finds justification through density functional theory, and one has a deeper understanding of the reasons for its successful phenomenology. Furnstahl, Serot, and Tang are the individuals primarily responsible for this development. Two new chapters on these topics are now included in Part 2. The chapter on the model QHD-I1 has correspondingly been eliminated, as has the chapter on Weinberg’s chiral transformation, which the author believes is more vii ...
