does one find stability in nomenclature of conversion

I personally can't find any stability in your nomenclature, but maybe I'm not looking hard enough. Maybe you can find what you're looking for in the
'detritus' thread.

Does Newton's first law of motion really imply no such thing as absolute rest? If an object in motion does continue to travel in straight line motion
unless acted upon by an outside force, does this imply that space is uniform and the present is the same present at every point in space at the same
instant and thus there is absolute simultaneity in the universe?

Asri,
I don't think people understand exactly what you are asking for. Can you try to phrase your question in a different way, perhaps with an example of
what you are trying to figure out?

I don't understand what the point of said bot would be. To annoy?
"There must be no barriers to freedom of inquiry ... There is no place for dogma in science. The scientist is free, and must be free to ask any
question, to doubt any assertion, to seek for any evidence, to correct any errors. ... We know that the only way to avoid error is to detect it and
that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think,
free to think what they will, freedom can never be lost, and science can never regress." -J. Robert Oppenheimer

" Who knows what evil lurks in the minds of men? The Shadow knows."
It could be to get information about the web site, it could be somebody's experiment in artificial intelligence, a Turing Test, or as you said, just
to be annoying. What is the purpose behind so many computer virus and worms? I'm just suggesting it because the post did not have any real meaning,
except what we try to read into it, it was most likely generated by some sort of program.
Another possibility is the fill the internet search engine with so many false positive 'hits' as to make it useless.
This is an example of what was easily available in the early 1980s.

I'm sure they can do a lot better now. Look at some of the 7th and 8th order imitations of Hamlet. It actually looks better than the OP. I can't
remember the actual name of a program that would do the deed, but maybe I'll remember it later.
I remembered; it was called Travesty. The main idea is it would 'read' some real text and after some evaluation of letter and spacing analysis would
generate something that resembled the original, but having no real intended meaning.

Oh yeah, this is an all-time classic (c.f. http://en.wikipedia.org/wiki/Dissociated_press). What I find so interesting about that article is to what lengths they had to go to optimize the
program and algorithm to make it run in reasonable time with reasonable memory consumption. I bet that was a few days of work with BASIC or C! With
today's technology (hardware and software), this is programmed in half an hour and takes only a few seconds to mangle multiple MB of text.
Nevertheless this simple algorithm is as fun now as it was then. IMHO the best thing about it is if you modify the lookup table. Squaring makes drivel
even more drively. Inverting the probabilities, on the other hand, makes long texts short and insightful poetry out of Hitler's trash (see below).
If there is interest in the (crappy) source code (156 lines of C++0x) which I used to generate the snippets below, I can post it either to this thread
or send it by U2U.
Examples:

Here's some more dangerous dissident questioning, enough to make the gangsters who hijacked the physics community throw temper tantrums, threaten
dissidents with persecution and worry about losing their access to funding. Read about The train-and-platform thought experiment here: http://en.wikipedia.org/wiki/Relativity_of_simultaneity
Now add to this two stop watches, one at each end of the train car, ie. front and back. Have electronic circuits arranged to stop each stop watch
when it senses a photon hitting the wall of the train car (ie. using a photocell). Start each stop watch while the train car is at rest relative to
the observer on the outside of the train car, start the train car and do the experiment as described. After the experiment, stop the train car and
bring the two observers and the two stop watches together. If the observers saw the photons hitting the front and back of the train car at different
times during the experiment (when the train car was in motion relative to the outside observer), then they should both see different times on the stop
watches, after the experiment even while both observers and both stop watches are in the same frame of reference. Yes, according to Einstein, two
people can see different readings on the same clock and yet at the same time Einstein says this is impossible. Remember in the twin paradox the dodge
used by the Einsteinian mystics to get assymetric time dilation. The twin that is accelerated is supposed to be the twin that undergoes time
dilation.

The stop watches and the observer in the car are in the same frame of reference. The observer sees the two stop watches ticking away in unison,
showing the same time. That observer sees the two photons reach the walls simultaneously, the stop watches freeze at the same instant and show the
same time.
The observer outside the car will notice that the stop watches are not synchronised, in fact the one at the front goes from being ahead of the one at
the back as the car approaches, to being in synch at the moment the center of the car passes the observer and the two photons start their trip, to
lagging the watch at the back. The two photons hit their respective walls at different times, the two watches each read the same time of impact but
appear out of sync.
The train stops, undergoing acceleration in the general sense, and either returns to the outside observer or he runs to the train; either way
introduces additional velocity changes.
When they all get together, the two stop watches show the same time - photo arrival instant reading - to both observers, one of whom will insist that
the photons reached their respective walls at the same moment as shown by the stop watches, while the other will insist that they did not and that the
watches were not synchronised at that time.
The two observers each grab the electronics box from one of the watch assemblies and hit each other over the heads with them, killing the other at the
same instant. An old man with a wild tangle of hair and wearing a sweater happens to be walking by, hears the noise of the paired assaults, enters
the train, notices the stop watches and pockets them, then wanders away.

Obviously, there is a prefered electromagnetic frame of reference, the aether. The velocity in the mass, length and time transformation equations is
the velocity relative to the aether and not the observer as in Einstein's fantasy. This is basically the philosophy of the Lorentz aether theory.
Also, stellar aberation from binary stars appears to show there is a prefered electromagnetic frame of reference, too.
In order to account for the Kennedy Thorndike experiment we could use a contraction hypothesis like the one described by E. M. Kelly in the attached
article and derive a modified Lorentz aether theory which is like Lorentz's theory except uses Kelly's transformation, but this assumes that the
Michelson Morley experiment was a complete null.

Well, since the level of the thread cannot get any worse, here is the silly code. It doesn't support multi-byte encodings, only ASCII or LATIN-1,
et.al. I removed the C++0x bits and it should compile under conforming C++ compilers. It's quite interesting that there is a distinct jump in quality
when increasing the order from 2 to 3 (syllables) and from 3 to 4 (words). Then it stays pretty much the same.

If you select and copy the code, it pastes correctly. Think that the extra lines are a mix of the board software and HTML - there's both real CR NL
and HTML BR at the end of each line.
This is fun to run on Lorem Ipsum, the result resembles some legal documents I've seen.
