If you had any understanding of the covariant derivative at all then
you'd know that made a slip and I readlly meant "That's not the
covariant derivative Ken. That's the absolute derivative." I.e. I left
out the word "the" which is obvious to everyone.

By saying this, you are still arguing that only the covariant partial
derivative is covariant. The covariant total derivative is also a
covariant
derivative. Saying "the" covariant derivative could actually refer to
either
one.

Well its quite clear that you are unable to understand the difference
between a proper name and an adjective.

It is the proper name because it is the proper adjective, but at least
you're
starting to backpeddle on your stance that it is not a covariant
derivative!

You're unbelievable waite. D/dT is not the "covariant derivative."

There you go pulling another 180. D/dt can be read the covariant total
derivative with respect to proper time, or just covariant derivative for short.
Your mistake is that you saw in one book the covariant partial derivative part
of a chain rule expression called by "covariant derivative along a path" and
automatically jumped to the conclusion that a covariant total derivative was
not a covariant derivative as well.

Sorry sparky but I've held fast to the CORRECT terminology.

You're just too arrogant to admit that you made an error.

Grow up waite.
