Last week I gave a colloquium talk at the Texas Tech math department, slides are here if you’re interested. One motivation for the talk was to advertise the book project I’m working on, which gives a lot more detail about these topics if you find something interesting in the slides.
The current state of the book is visible here. There are 31 chapters done, about another 5 to go. I also need to go through the entire thing again and reconcile various choices of convention that currently are not necessarily consistent. I plan to get back to work on this in a couple weeks after fall classes are over here, have something like a finished draft of a book done around February. The next project will be to get back to what I was writing long ago on Dirac cohomology and make some more progress with that.
For the next few days though, will be taking it easy, and eating turkey. Happy Thanksgiving to all!
Update: The volume of the Feynman Lectures on Physics devoted to quantum mechanics is now available freely online here. This is a masterful introduction to QM from the perspective of a great physicist. What I’ve been writing in some sense is intended to function best as a supplement to this and an explanation of how it is related to some basic concepts in mathematics.
