On the subjects of absolutes. Man made Math. Man made computers.
Computers use Math. I'm not sure that's proof of absolutes. It seems
more like creating a tool and then creating another tool from the first.
I will agree Math usually uses absolutes. However, I think it
gets a little fuzzy when you get into inference and imaginary numbers.

Unless we are making a faulty assumprion. We might think they are absolutes, and they might even act like absolutes so far, but that doesn't mean they necessarily are.

Imaginary numbers aren't fuzzy at all.

Statistics? Bayesian Inference? Now that's fuzzy.

Imaginary numbers, being numbers which represent numbers
which don't really exist.....that sounds a little fuzzy to me.
It appears some math gurus were sitting around and
trading math problems when they discovered,
"Oops, when I try to compute that, there isn't
a valid answer."

Well shucks. This Math thing was working out pretty well until
we ran into that little oopsy. Let's keep the system but add
sometthing to it to handle these occasinal cases. Yes, since
it doesn't work with the numbers we already have, we'll make
up something...imaginary numbers.

I can only assume they were very brillent and more than a little
stoned.

And you can't divide by zero. (You don't even get lazy eight, some say.)

"Not Defined" does not make a very good argument, in my opinion. It sounds a little like the "God works in mysterious ways" cop-out.

Zeep, considering how useful imaginary numbers are, I'd hesitate to criticise.
On the absolutely most practical level, imaginary numbers are no less real than irrational numbers -- if you draw a right triangle, there's no way it came out exact down to even the 100th decimal point (that would be smaller than the planck length), let alone all the rest of the way.

So, irrational numbers are a place marker which allow arbitrary precision. Imaginary numbers are a place marker which allow freer thinking about functions: First, you can express ANY polynomial in terms of its solutions; second, many integrals can only be calculated through 'analytic continuation', in which we devise a complex function which has the same values on the real axis as the real function did, and then integrate that.

Aside from that, imaginary numbers are mainly used as a compact way of representing a two-dimensional vector space in which rotations about the origin are of prime importance. There are many such spaces in physics and engineering.

As for 'undefined' when speaking of zero, well, take 1/0. Is it  infinity (as we get approaching from above)? or... negative infinity (as we get approaching from below)? On a more pragmatic level, division by zero typically indicates the question is wrong.

Dunno, let's just give it a cool little symbol and base theories on it that predict extra dimensions.


By the way, how do you type the damn infinity symbol on a keyboard?

Type the number 8 and leave instructions to "turn head sideways".

I don’t know I just use the "insert symbol" feature in word then copy and paste.

Yea, but fake computers can run more than a couple programs.
