Nuclear Physics from the Quark Model with Chromodynamics

Part of the Acta Physica Austriaca book series (FEWBODY, volume 27/1985)


It now seems nearly certain that nuclear physics can be derived from quantum chromodynamics. In these lectures I describe the ideas and methods underlying a possible route to such a derivation through the quark model, and some of the progress that has already been made along this path.
