[Perl-AI] expressiveness in notation

http://www.scn.org/~mentifex/theory5.html is a Theory of Cognitivity.

Uhh. I must be missing something here. This giant page has
nothing at all about TEX rendering, notation or even the concept
of expressiveness. What is the reply here?

There is none; your posting simply contained keywords that triggered
his spambot. He's a crank:

Math, like everything else, needs an enema. Style and content are
mixed up all over the place:

x is a scalar, but B<x> is a vector.

R stands for range, but ornate R (&real;, for those keeping score in
HTML) stands for the set of real numbers.

Probability folks use middle-dot as a placeholder, like $_. (OK,
that's pretty cool.)

Inconsistency across disciplines: most fields use I<i> for the square
root of -1, but electrical engineers already use i for current, so they
use I<j> for the square root of -1. I hope this has resulted in at
least one electrocution.

Requires too much flexibility from typesetting packages (consider
Eulerian notation, where the eighteenth derivative of "f" is "f" with
eighteen dots over it, or cascading exponentials (2 to the 3 to the 4
to the 5 to the 6 to the 7 makes for a pretty eentsy 7).

People who flip A upside down and turn E around left-to-right just for
kicks deserve no mercy.
