You must be joking.

One can pull any physics textbook, new or old, off the library shelf
and one will encounter a thicket of abstractions and endless equations
that provide very little, if any, humanly relevant insight.

The authors must do this or else they will be accused of incompetence
by their academic colleagues.  Such dry rigor is the accepted fashion.

I am currently studying differential geometry (DG) on my own.
DG is the mathematical underpinning to both Lagrangian/Hamiltonian
mechanics and Einstein's general relativity.

However, I find that most scholarly DG books are totally useless.
For one thing, DG is a very visual subject and most books present
a paucity of imagery.  This is a pure travesty!

Fortunately, there are some web sites that take a more casual,
and more proper, but still thorough approach to DG.  These
web sites are hard to find, however.  Here are a couple of
examples:

https://liavas.net/courses/math430/

https://math.franklin.uga.edu/sites/default/files/users/user317/ShifrinDiffGeo.pdf

Before too long, I will be publishing several web pages that
will present DG as it should be presented: using GNU/Linux
computer algebra and video animation.
