Here is the plan for while I am away. The best place to find the videos and the notes is on Spark . If you are not officially enrolled, the links to the Screencast versions are Natural Units and then Four-vectors and
Basics 2 .
It is unfortunate that UMass is closed until 11:00 today (Jan 29), especially when coupled with my being away next week. I had been counting on finishing the basic construction of a field today. I will adjust the plans for the classes and update you later today. I will put together an email list for everyone who signed up on Tuesday and will send around information that way. I will also post all info here. Enjoy the morning off, but check back later for more info.
