Such was the situation prior to its corruption by Einsteinians .
They're not discussing things for

technicians. They're not discussing things for "engineers" or
"managers." They're discussing them for human, and for the sake of
_only_ finding stuff about nature; nothing else.

One can pull any physics textbook, new or old, off the library shelf
and one will encounter a thicket of abstractions and endless equations

DG is the mathematical underpinning to both Lagrangian/Hamiltonian
mechanics and Einstein's general relativity.

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

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.
