It's implicit when we talk about definition that we are refering to the foot as measuring unit.
My first quote was taken from that same precise post.
"We will not have to change definition" was in response to crudus' comment that a 13 inch long foot can exist as soon as we redifine foot.
And notice how I say we will not need to change the definition of foot as lenght measurement unit for there to exist a footlong piece that is measurably 13 inches.
So, I'm still a bit confused.
No you are not confused. Saying a "13 inch foot exists" and "to exist a footlong piece that is measurably 13 inches" is not the same thing is it? But now that you replaced it I think we finally are in agreement 100%.
But if the item being measured is 13 inches long according to the one measuring it, you can no longer say it is 1 foot long. You just said there is no absolute length. Why is this item's status as being 1 foot long somehow exempt from that?SakSak said:All measurement by its very nature is dependant upon the relative speed of the observer in relation to the object measured. Therefore, there is no absolute lenght.
So, with enough speed difference, a foot long piece will measure 13 inches therefore, to the measurer, the footlong piece is 13 inches long. Making it a 13 inches long foot.
It is not. However, when the item was constructed, it was done sone in the same frame of reference as the item.sunburst313 said:But if the item being measured is 13 inches long according to the one measuring it, you can no longer say it is 1 foot long.

That was very well worded. My only issue with your statements was that you claimed there was no absolute length while your idea here relies on the existence of an absolute or "proper" length within an object's rest frame. We're on the same page now. Well done sir.SakSak said:-snip-
This seems to be a self-refuting argument.Shankity Stick said:I dare anyone to disprove ANYTHING, if you factor in magic, other planets, and alternate dimensions. My logic is that we can't prove that something definitely doesn't exist/ happen somewhere out there. That is the one thing that is impossible. But by all means, try to disprove something to me.
P.S. anyone trying to disprove something visual I?m sick of repeating my self so here goes, maybe x is happening, you just don't realize it.
That was a simple proof by contradiction and I can't find anything wrong with it. It was a "widely-known fact" the earth was the center of the universe and everything revolved around it. They got pretty creative with forcing equations to prove themselves right too. Various astronomers had the burden of proof to prove the the sun was the center, our earth revolved in an elliptical pattern, etc. The point is you finally were able to back up your argument with solid evidence which is what I was going for. Computers are told how to do the calculations like addition. I am not saying programmers told the computer what 3+4 equals. The computer doesn't need to know. The computer is told how to take input and it is told what to do with that input and it gives an output. This is what I mean when I say computers have a set response: they only do what they are programmed to (not necessarily what you mean them to do).MurderousToaster said:If your computers didn't perform the calculations and sums, they would not work. That is fairly obvious. You think someone went through every mathematical possibility, programming the correct answers? That would be ridiculous. They'd still be working on the first calculator now.
Whatever. I give up with you. You're flat-out refusing to prove that dividing by zero is possible until I, I dunno, go into the past and ask the first person who discovered you can't do as as to why.
As a side note, it is you that is just "shutting your ears and declaring victory". You're just saying "Give me proof!" when it is a widely-known fact that you cannot divide by zero.
Whatever. I'll just copy-paste from Wikipedia, since you seem to feel that you don't want to actually respond until I provide something.
In mathematics, a division is called a division by zero if the divisor is zero. Such a division can be formally expressed as a / 0 where a is the dividend. Whether this expression can be assigned a well-defined value depends upon the mathematical setting. In ordinary (real number) arithmetic, the expression has no meaning.

Ok, I dipped into philosophy by referring to Kant's das Ding an sich(or thing-in-itself). What that means is we can change the definition of a circle as much as we want but we still have this thing that is round and has no corners which is a circle's das Ding an sich.Vitor Goncalves said:Actually language did get in the way. A circle can define both the Circumference (all points in a plane, which by definition is 2-dimensional, at same distance the same from the centre) or the entire disk within the circunference. So a circle can indead contain corners, just not in its limit. The circunference on the other side can't if we keep the same no changing definition policy. On a side note, the prevalent definition in english for circle is the first, but its not the prevalent definition in other languages I know (french, spanish and portuguese), as it is the geometrical place defined by points in a plane of at same or inferior distance from a point denominated center. And the curved line delimiting it its always a circumference. So somebody already changed the definition, many centuries ago I believe.

The statement "You do not exist."
This is because logical absolutes are not dependant on perception or even the state of reality.
