Okay, you can laugh if you want, but not 'till you've read the whole
thing. This is something that's been bothering me for a while, and I'd
kind of like to get it cleared up.
Some time ago (Whilst a mathematics student in college)I toyed with
the idea of numbers (as whole and real values) being represented on a
cartesian plain as a point in space, and then being 'rotated' around
x=0 & y=0 to give a point representing the same value, but in another
position. If it's supposed that the observer is at x=0 & y=0, is it
fair to say that the value in it's 'rotated state' is still the same
value, but just seems to be different because it is being judged from
a different perspective. I guess what I'm trying to do is place a real
life object in the same situation as the point on the cartesian plain
which represents the real value of this object.
Okay, here's what I really mean.
Y
|
|
5|
4| *
3|
2|
1|
----------0---------- X
-5-4-3-2-1| 1 2 3 4 5
-2|
-3|
-4| *1
-5|

Above, * represents the value 16, and I get it's initial position on
the cartisian plain from x = root of 16 and y = root of 16, hence x =
4, y = 4.
I now have a point that represents 16 on the cartesian plain (to my
mind anyway).
If I rotate * through 90 degrees around the point 0, it will end up
in the position shown by *1. At this point x is still 4, but y is now
-4. To the observer at point 0, I have taken the value on the
cartesian plain (16) and rotated it around so that it represents -16
(x=4, y=-4, and to arrive back at the true value of the rotated value,
x*y = -16).
This can be performed with any value at any angle by using the
expression below..
{n} = nCos(2t)
t
I think that we spend too much time thinking of numbers and values as
flat boring two dimensional objects, what if they could have sides, a
back and a front, and maybe on a three dimensional plain, a top and a
bottom.
Okay, the men in white coats are comming soon... but is any of this
valid?
