GR: In

fact I love to learn new things, but the language you use makes no sense to me

mathematically. The fact that you think a variable is a function is a big

problem mathematically but let’s move on.

No let’s not. You are the one saying that I think a variable is a function. I

have never said such a thing.

What

I said was “perceptual variables are a function of input variables”.

Well

here you are saying it,

You

keep reading that as though all I said was “perceptual variables are a

function…” which is kind of infuriating, especially since I wrote what I

meant

Maybe but

it makes no sense in its statement form. When I asked some colleagues nobody

could make head or tail of it. Your statement is like saying verbs and nouns

are the same and interchangeable.

in

mathematical notation: p=f(s1,s2…sN). Here a variable, p, is some function, f(),

of the input arguments (which are varables), s1, s2…sN.

The

function, f(), is not the same as the variable, p.

Correct

And not

the same as the input variables either.

I’m

willing to bet that this still makes no sense to you mathematically –

Perfect

sense.

or

at least that you will say it doesn’t-- so I’m probably wasting my time.

But if this really doesn’t make sense to you mathematically then I see no hope

for us ever communicating in what I consider to be a rational manner.

Your

statement it not what you are saying here. There are not consistent. A function

transforms the variables, it’s not variables in itself.
