Well, let's see. Suppose you tell me how you propose to measure the
length of something without bringing anything else into the picture...
This ought to be fun...

This is really fun...

Let there be a meterstick in pure isolation from everything else in
the universe...

Now genius, tell me, does the meterstick have a defined length or not?

Let's see. You were going to tell me how you propose to measure the
length of something without bringing anything else into the picture.
Have you done that? Not yet.

Maybe I was too fast for you

Let there be a meterstick in pure isolation from everything else in
the universe...

Let's take it one by one...

Did I bring anything else into the picture? NO.
Does the entity have a length? YES.
What is its length? ONE meter.

How do you know that? Because it has "One meter" stamped on the side?
If you have a pig that has "cow" stamped on the side, is it a cow?

I don't have a pig with a cow stamp and neither do you.  I can see why
you are confused.  Your logic borders on insanity.

The question, which is really easy for normal people, is, does the
meterstick have a length?  Only insane people would argue it does not.

A meter stick has a length when it is measured at rest. It also has a
length when it is measured in motion. Those two lengths are not the
same. The fact that you have *called* it a meter stick in no way
guarantees that the length is a meter in both circumstances. And in
fact, the instruction manual that comes with the meter stick
specifically tells you under which circumstances the meter stick's
length is a meter. You HAVE read the manual, haven't you?- Hide quoted text -

I'll repeat the question stupid:

Does the stick (meterstick in this case) have a length?

I already answered the question. Please read above.

Good.  We agree that the meterstick has a length.  Since this length
exists while the stick is in isolation, then this length is the
INTRINSIC length.

Next problem...

Sorry, no. Intrinsic implies frame-independence. I've already answered
that question. Please read above.- Hide quoted text -

I know your answer.  You deny and affirm the existence of intirinsic
length.  What's new?

No, I deny the existence of intrinsic length, period. The fact that
you point to something that I say exists and you call it intrinsic
doesn't change anything.

If you pointed to a goat and said, "Does that thing over there exist?"
and I said, "Yes," and you then said, "There, you see, purple
zipniggels exist" -- well, that would not be an admission on my part
of the existence of purple zipniggels, would it?- Hide quoted text -

The liar speaks.  I'll refute this liar, and let us watch him weasel
again, and I shall refute him once more...

Let me begin with a definition:

Intrinsic - of or relating to the essential nature of a thing;
inherent.

That's a lovely definition from a dictionary of colloquial usage. Has
little to do with the definition as used in physics.

For example, here is the definition of momentum from a dictionary of
colloquial usage:
Momentum - an impelling force or strength
Note how this is not only inappropriate with the physics meaning of
the term but also *inconsistent* with it.

Let me recall that stick I have floating all by itself, in complete
isolation.  Complete isolation.  No observers.  No other sticks.  This
stick just happens to be a meterstick.

Now PD would deny this meterstick has a length.

You lie. I've already told you it has a length. More than one, in
fact. It has a length in each and every inertial reference frame. At
no time did I ever deny that it has a length. I *did* deny that it has
an intrinsic length, but you have lied about what I said.

Enough fluff.  What is the length of the meterstick in isolation?
Since you say it has many lengths, I'll leave it to your psychiatrist
to help you make up your mind and choose one :)

Why would I need to choose ONE when it has many?

And why do you lie?

So in your schizophrenic reality, the isolated meterstick, devoid of
any external observer, except itself, has many lengths, but not one
of these are valid in describing the stick?

They are all valid, one per reference frame. Choose a reference frame,
and the stick has a valid length. Choose a different reference frame,
and the stick has a different valid length.


Many lengths but not one?

Almost sounds like "water water everywhere but not a drop to drink".

Length length of all sizes, but not one to describe the stick.

Ladies and gentlemen, you have just seen the theory of relativity in
action...

Yes, indeedy. I find your arched-eyebrow incredulity charming, in its
adorably oafish way.
