Note for physicists

My goal in the remainder of this chapter is not to present a specific ultimate model for physics, but rather to discuss at a fairly general level some features that I believe such a model will have, given the overall discoveries of this book, and the specific results I have described in this chapter. I am certainly aware that many physicists will want to know more details. But particularly in making contact with existing physics it is almost inevitable that all sorts of technical formalism will be needed—and to maintain balance in this book I have not included this here. (Given my own personal background in theoretical physics it will come as no surprise that I have often used such formalism in the process of working out what I describe in these sections.)
