Well, Cliff would be correct in that mass *always* has the *property* of
momentum, even if that momentum happens to be zero.

PV:

Cliff and I do a little dancing Minuet on certain subjects. He gets so
flustered when challenged to support some of his claims with actual
evidence or corroborating sites. I know I've won when he gives up all
semblance of responding semi-rationally, especially when his comments
devolve into mentioning "lint", "nuns", "Aristotle", "Star Trek", etc.
LMAO!
Actually this is kind of odd. Cliff doesn't usually repost months old
articles since new and juicy stuff is presenting itself all the time.
But here YOU are seemingly cutting in on an old dance of ours and
standing in for Cliff. Did you guys attempt to orchestrate this
situation offline? Color me curious.

But as far as your own comment above; First, you should know better
than to use the term "always" in reference to anything. Momentum may
not be an intrinsic property of mass - and even mass may not be an
intrinsic property of matter. The postulated quantum Higgs field, that
supposedly permeates the whole universe, may create the "effect" of mass
in quantum particles that would be essentially massless without it.
News at 11:00 (Year 2025).
Some of the string theory variants also seem to bear watching for
validation, since some of them touch on the subject of field generated
inertia/mass.

Back to your comments, momentum is definitely a property of mass in
motion. P=mv
But NO motion = zero momentum (in the reference frame considered). Now
Cliff claims that mass always has a vector, but has never been able to
adequately deal with my often repeated question of just which direction
that vector points in a stationary object. He often brings up time as
being the vector direction - which is unsatisfactory. He also tries in
interject unit vectors - which also is unsatisfactory.
What MAY be satisfactory, IMO, is a Null vector.

========================================================================
http://en.wikipedia.org/wiki/Zero_vector

Null vector

In linear algebra and related areas of mathematics, the null vector or
zero vector is the vector (0, 0, ?, 0) in Euclidean space, all of whose
components are zero. It is usually written or 0 or simply 0.

For a general vector space, the null vector is the uniquely determined
vector that is the identity element for vector addition.

The zero vector is unique; if a and b are zero vectors, then a = a + b =
b.

It is the result of scalar multiplication by the scalar 0.

The preimage of the zero vector under a linear transformation f is
called kernel or null space.

A zero space is a linear space whose only element is a zero vector.
=========================================================================

Now it would seem that a Null vector, or Zero space, is pretty much the
same thing as having NO vector at all - since all the magnitudes and
directions seem to be as close to non existent as possible but yet still
have the NAME vector.
So the term zero momentum BEING a FORM of momentum may be similar to
someone asking me if I have any money. Sure I've got money - Zero
money!


collision theory, is actually a very important state!

Ah, but multiple bodies are virtually NEVER part of the particular
comments I make about the linear momentum of a stationary object, so are
irrelevant.


Say, you two really talk off-line?

Off and on. My free time is variable, I've yet to answer some of your
E-mails.

Man, I'd like to be the fly on DAT cyberwall. :)

They're not for public consumption, there are images to maintain - ya
know. LOL


Hey Bottle, when are we going to get back to covalency, huh??

I only vaguely remember what the covalency/metallic bonding subject was
in reference to. Probably the "wringing" of Jo blocks. No time to play
right now - we're so busy I have to work 10 hours tomorrow to get some
satellite parts I'm working on out by Tuesday.
