Tensor and scalar substitution

Perhaps you should learn what tensors actually are
before attempting to "represent" them. Hint: they are not matrices (though under
certain circumstances their components can be arrayed as a matrix).

You can only fool the self-styled physics with these myths. In any
applications, treating tensors as matrices, you will never go wrong.

The root of these myths about tensors came from the misunderstanding
of the metric. The following post explains so. shrug

The following sums them up why myths rule in the modern study of
physics. shrug

** FAITH IS THEORY
** LYING IS TEACHING
** NITWIT IS GENIUS
** OCCULT IS SCIENCE
** PARADOX IS KOSHER
** FUDGING IS DERIVATION
** BULL**** IS TRUTH
** BELIEVING IS LEARNING
** MYSTICISM IS WISDOM
** IGNORANCE IS KNOWLEDGE
** CONJECTURE IS REALITY
** PLAGIARISM IS CREATIVITY
** MATHEMAGICS IS MATHEMATICS

Yet when asked for books to read on the subject, perhaps the ones you
read, you argue it is none of their business.

That is correct. Mostly, yours truly cannot recall. shrug

What is your credential on the other hand to ask yours truly this
credential question, college dropout?

In the meantime, revisiting how the self-styled physicists understand
what a metric is, you got to really try to be as ignorant of these
self-styled physicists. For example, the metric represented by the
identity matrix is dimensionless, and yet the self-styled physicists
were able to conjure up the nonsense idiotically claimed so in the
link presented above. Man, you got to try to be that ignorant.

Is ignorance really knowledge? The self-styled physicists seem to
think so. shrug
