I’ve purged about 30 pages of material related to field Lagrangian densities and Maxwell’s equation, replacing it with about 8 pages of new less incoherent material.
As before, I’ve physically ripped out all the pages that have been replaced, which is satisfying, and makes it easier to see what is left to review.
The new version is now reduced to 333 pages, close to a 100 page reduction from the original mess. I may print myself a new physical copy, as I’ve moved things around so much that I have to search the latex to figure out where to make changes.
