13. To start things off in the second semester of the course, we want to understand the structure of the state spaces and the nature of the observables associated with quantum systems containing more than one (and in principle very many) quantum mechanical particles, some of which may have intrinsic internal degrees of freedom, like particles with spin, or other composite systems like collections of atoms. Unlike the lectures of Quantum One, in this semester of the course, I intend to break the lecture videos into smaller independent topics, which hopefully will load more quickly, and won’t produce such large files. So the beginning of our discussion on many particle systems will appear in the video which follows this one in the table of contents on the course web page. 13
