I understand your point if taking a distant view from outer space.

At close range however the moon is revolving around the earth, and the
earth is spinning on its axis. That says to me that the geographic
position of the barycenter is constantly shifting with respect to the
earth's surface.


"It" doesn't shift. It's just never in the same place.

No. It induces a wobble in the larger object. That's how NASA, Ames
and JPL do those extra solar planet searches with the Spitzer X-Ray and
Hubble telescopes - they look for the star wobble and aim for where the
planet should be based on the arc of the wobble.

The barycenter is the barycenter - the center of mass of any system of
objects.

Hmmmm - I guess you could put it that way in terms of geography. You
could also say that the Earth is spinning around the barycenter.

For example, it you had two bodies on the same plane orbiting each
other, the barycenter is located in space between the two - it doesn't
move as long as the masses are balanced by the mechanical motion.

Or take another case. Say you have a large rotating body around which a
smaller, but massive body rotates. The barycenter is just above the
surface of the larger body. The barycenter never changes position - it
is the balance point, but the structure below it changes.

Good God, I haven't worked with these concepts in ages. I have a
headache. :)

Here are several online nautical word/phrase dictionaries, one that even
offers a nautical word of the day:

Sorry I made your head spin.

But wait, it was already spinning...

No sympathy here. I've been reading Isaac Asimov's "Asimov on
Physics" in my spare time. It is an incredibly lucid and readable
account of some very esoteric concepts. Published in 1976 but
available used on Amazon.

If you took my reply personally that is your problem. I was only trying to
help you and the NG with other resources on how to locate "nautical words of
the day".

Don't take things so personally Chuck..............breath

Have a nice night Chuck!

Chuck,
Now that we have those 3 links, we no longer need to discuss boating in
the NG.

Thanks.

My personality has been kicked around enough already.

That's a frequently recurring theme. The value of Google or other
search engines is to locate sources of often conflicting information.
The value of a NG, (IMO) is to create a place where people can discuss
and debate ideas that relate to the topic, share personal experiences,
etc. The NG would be a very frustrating format for anybody who felt
their only purpose was to extract an enormous amount of general
information, and I agree with JimH, Shortwave, and others that there's
no shortage of free information already circulating on nearly any
conceivable subject. Much of that free information is worth exactly
the selling price.

I didn't, so I have no problem.

The nautical word item seems to generate quite a bit of on-topic
discussion, doesn't it? I'll bet that's pretty surprising to somebody
who wrote that the original nautical word posting was a "joke that
everybody else got except you."

Life is full of surprises. Some of them pleasant.

It's in my library - autographed no less. :)

Did I ever tell you the story of how I met him?
