ACtually, NO, it wasn't. Newtonian Mechanics DOES NOT apply to the
orbital motions
of bodies in space. To the THEN CURRENT mathamatical accuracy of
observation it
MATCHED and predicted the motions. But to todays accuracy, it FAILS.
A theory can get the right numbers to a given level of accuracy and
still be
basically crap at the fundamental level of it's axioms and basic
interpretations
and understandings. Or if not 'crap', at least not-relevant.
Too many people don't understand the difference between 'truth' and a
scientific
theory. Theories that express the result in a number are true only to a
given
level of precision. Look at all the hacks needed to make Ukawa's theory 
work to become QED! Was Ukawa wrong? The basic model used to come up
with his
equation, which is the 1st order QED term, is in direct conceptual
disagreement 
with the models used to come up with the higher order expansion terms in
QED.
Doesn't that say something about that whole theory?

Though the previous doubt-er might not have had any eloquence, he had
reason
to doubt, and I think the *blind acceptance* of many of the current
theories
shows a conceptual misunderstanding of the nature of scientific
reasoning, thought,
and theories in general.

It takes two people to argue. If you find someone too incendiary, IGNORE
THEM.
That's all it takes to stop an argument. Or take the argument off line
to 
private e-mails.

No, of course it wouldn't destroy the theory of evolution, for the

Good.  You should have no problem telling me about just 10 of those
thousands.  The info that will be required to formulate a well-founded
decision that we have transitional fossils on our hands:
a) how many samples
b) was geographic variation taken into account
c) how many features were looked at
d) what were the ages of the various samples looked at
e) were all features looked at
f) were all the available samples considered

This is microevolution.  I'm interested in macroevolution, the idea that
new organs and new limbs can appear whereas before they didn't exist. 
That's the main claim of the theory of evolution: the claim of a blind
watchmaker constructing intricate and complicated things.  A change in
allele frequencies, as when black moths start increasing in numbers
compared with white moths because of a change in environmental
conditions, is not even close to a situation where a new organ develops. 
You don't need evolution to say that an allele frequency will change in
the case of black and white moths.  You just need genetics.  For the
development of a new organ, however, you need a lot more than changes in
percentages of population members having a certain wing color.

I can see gravity's influence in action.  Can I see a new organ
developing whereas before it wasn't in that organism?  If you say "yes,"
please include a journal reference.

"Define for us all of the kinds which are so clearly delineated."  You
are right.  I do "find such a task insurmountable."  I'm not a
paleontologist.  A paleontologist would be the person to ask.  You might
want to start with Charles Darwin and Jean Baptiste Lamark:
"But how could a division of the organic world into discrete entities be
justified by an evolutionary theory that proclaimed ceaseless change as
a fundamental fact of nature?.... Yet--and this is the irony--both
Darwin and Lamark were respected systematists who named hundreds of
species.  Darwin wrote a four-volume taxonomic treatise on barnacles,
while Lamark produced more than three times as many volumes on fossil
invertebrates.  Faced with the practicum of their daily work, both
recognized entities where theory denied their reality."[Gould, _The
Panda's Thumb_ (1980), 205.]  Instead of asking these two
paleontologists, you could look at a guide book for identifying fossils.

Look at the needle.  Some of them have a slider, made up of a
few turns of copper wire, on one end of the needle.  This is
to balance the dip of the magnetic lines of force with which
the needle tries to align itself.
When you get to Kuwait, see whether the north end of the needle is
hitting the glass or is so far above the markings that it's hard to
read accurately.  If it is, take the cover glass off and slide the
copper wire as close to the pivot point as it will go.  If you
don't want to do this yourself, go to a jeweler.

Walter Alvarez and his associates have located some sedimentary
features that support the idea that there was a major meteor
impact at that time.  He has also put together a fractional-orbital
model that explains the worldwide distribution of tektites from
this event.  I haven't seen this information in published form

I can return the favour:
Since we proposed punctuated equilibria to explain trends, it
is infuriating to be quoted again and again by creationists--
whether through design or stupidity, I do not know--as admit-
ting that the fossil record contains no transitional forms.
Transitional forms are generally lacking at the species level,
but they are abundant between larger groups.  Yet a pamphlet
entitled "Harvard Scientists Agree Evolution Is a Hoax" states:
"The facts of punctuated equilibrium which Gould and Eldredge...
are forcing Darwinists to swallow fit the picture that Bryan
insisted on, and which God has revealed to us in the Bible."
 -- Stephen Jay Gould, "Evolution as Fact and Theory," _Hen's Teeth
and Horse's Toes_.
Gould does NOT say that there are no transitionals (that would be
silly of him), only that there are FEWER than would be predicted by a
slow, gradual, evolution as (probably) envisioned by Darwin. We DO
have oodles of transitional forms between higher groups, and indeed
also between species (although Gould does not like them - they mess
with his theory of punctuated equilibrium). Gould does NOT say that
there is no evolution, he is only disputing the SPEED (he thinks any
species is normally kept in stasis by stabilizing selection,
interspersed with furious change when selection changes).

Exactly as is predicted by the theory of natural selection. Selection
is HARD. If there was variation in things like, say, how to go through
mitosis or how to store DNA then the organism is dead in the water.
The LESS critical a trait is, the more variation there will be, since
the penalty on aberrant forms is mild enough to be tolerated.

Yup. They do not evolve at a constant pace - they evolve when

It won't surprise any geneticists or paleontologists. Especially not,
I might add, some of those you've quoted, like Gould. You can easily
verify this by actually READING THEIR BOOKS instead of quoting out of
creationist litterature. Or you could ask in, say,
sci.bio.paleontology.

Both, really. Firstly evolution isn't directed; nothing in the theory
says anything about the order of appearance. However mammals are a
rather late product of the chordate line, and if we found them in
burgess shale they would predate what we consider to be their
ancestors. That would clearly mess things up for evolutionists pretty
badly. Luckily we, contrary what creationism predicts, haven't found
any mammals in burgess shale.
  The theory of evolution is
: essentially a particular view of history.  You have the Marxist view of
: history, and then you have the evolutionary view of history.  Precious
: few predictions here.
I can't post-predict past unique historical events any more than I can
predict future unique historical events. I can't predict which horse
will win the races in a week, but I can predict that one will. I can't
predict which animal gives rise to any other animal; there is no way
for me to predict that, say, frogs will, in a few hundred million
years, give rise to the group X. That doesn't mean that I can't make
predictions: I can predict that allele frequency will change if I
apply a selective pressure; I can predict that the offspring species
will be quite similar to the parent.
I can not say anything about historically unique event. Noone can. The
problem historians face is that they nearly only deal with
historically unique events.

No, because there'd still be thousands of examples where it fit. One
anomaly does not necessarily mean that the theory is wrong, only that
we'd apparently have missed the real ancestors to mammals (if one was
found in Burgess Shale). Do you see the the point? If it was shown
that the problem was with the theory (such as that specific creation
could be observed, that it was 100% certain that our Cambrian mammal
had no ancestors) then evoultion would be falsified. As it is, since
we'd view this find in the light of millions of supporting finds, we'd
have to ask ourselves if we hadn't just missed the important
pre-cambrian fossils showing the evolution of mammals.
A mammal found in cambrian rocks is only a problem because it would
make the series of later fossils unambiguously becoming more and more
mammal-like redundant.

Sorry, but this was way way off....
There are 2-5 eclipses/year, but not all are total.  On the average there
are only about 0.7 total solar eclipses/year.
The zone of totality can be anywhere from 0 to 265 km wide -- let's
assume an average width is 100 km.  The length of the zone of totality
is perhaps some 70% of the Earth's diameter, or 9000 km.  Thus the
zone of totality covers 9000 * 100 = 900,000 km2 of the Earth's cross
section.
Now, what about the area of the Earth?  The cross section area of the
hemisphere facing the Sun is:   pi * (6370**2)  =  127 million km2.
The hemisphere not facing the Sun is equally large -- the total cross
section area is thus  ca 250 million km2 (note that this is half the
actual surface area of the Earth).
Thus, the zone of totality of each total solar eclipse covers, on the
average, 900,000 / 250 million = 0.0036 of the Earth's surface.  Since
there are 0.7 total solar eclipses/year, each year 0.0036 * 0.7 = 0.0025
or 1/200 of the Earth's surface will experience totality.  During 70
years  70/200 = 0.35 of the Earth's surface will experience totality.
Thus the probability of seeing totality once during a 70-year life
will be approximately 0.35 (i.e. 35%).  This figure is independent on
how much one travels around, assuming one never makes any effort to
travel to a zone of totality.

Academic research is usually published in the open and available
internationally.  Most government sponsored research (in non-military
fields) is also published and available internationally (US research
anyway).  Most private companies, understandably, regard the fruits
of their in-house research as being theirs alone (at least for the
time specified by national and international patent laws) and you're
not likely to change that anytime soon.
At least, that's the way things work here in the US.  I suppose there
must be some countries where publication is witheld.  However, it's
usually to everyone's interest that research be published - even if
such publication is accompanied with a patent claim on any related
technologies.  This is well understood and has been for some time.
How is this new proposal different?  All I can tell is it sets up some
bureaucratic nightmare that would probably inhibit rather than promote
free exchange of ideas.  Who's going to cover the cost of such an
organization?  And if I refuse to pay, does that mean I'll be denied
the data?
Libraries, postal services, phones, and internet already accomplish
more than this proposed organization.  Support those institutions and
you'll be doing everyone a greater service.
And, is there a specific newsgroup where this is actually an
appropriate thread?

Very interesting. But why all the fuss about creationalism vs evolution
in the first place! Of course evolution is real..we can see it with
micro organisms etc. Creationalism is also real (maybe). If there is
a God does he not create us in his image in the sense that he fills us 
with virtues and
positive qualities. The mistake comes about by an initial false 
assumption about who God really is! If there is a God then he is
a spiritual being with no 'human' form. Thus comparisons cannot be made
with the world of matter. And if someone cries 'prove it' , I can
equally well turn round to a Physics researcher and say 'prove 
superstring theory'. The debates are pointless and without end..AS an 
Engineer I get worried about both camps. Are Sientists beginning to 
treat Science as a religion and some Scientists becomming the new
'priests'! And those who disagree are branded 'heretics' by both sides!!

	Perhaps I am too pragmatic, but I tend to take the standpoint that
"what works to a given level of precison is good enough.   By saying that
halley's comet was a confirmation of Newtonian mechanics, I meant that
to a first level of approximation newtonian mechanics applies to 
bodies in space such as comets.  Sure, the basic "philosophy" between 
newtonian mechanics and  theories such as general or special relativity
are in disagreement, but at the speed of halley's comet and the masses
of the objects involved, newtonian mechanics gives a description that
was "good enough".  So its not that newtonian mechanics was wrong,
but rather that newtonian mechanics is only an approximate description.  As
a results it Fails under certain circumstances.  The newtonian model is better
than say a model that says something like "doubling the mass of the comet,
will double the rate at which it approaches the sun.  This statement is
an even worse description than newtonian mechanics.  In this respect 
newtonian mechanics is better than the model I described above.
	Thus, at the time Edmund Halley, did his work, Newtonian mechanics
was the best model he had to work with.  This was my whole point with my
original statements.  
	As you have stated there are some severe problems between The big Bang
thoery and some estimations of the age of some stellar objects.  That it true.
What people should be doing is trying to come up with better theories
of the origin of the universe.  Fred Hoyle, had a steady state model that
matched observations for a while, but I have heard that it no longer
mathces more recent observations as well as the Big Bang models.  Thus I 
view the Big bang model as the "best guess" we have at this time.  If you
have seen some models that do a better job of matching known observations,
please e-mail me the references.  I am perfectly willing to change my
mind, if a better theory comes along.  The Big Bang model may not be correct,
but it seems like we don't have another one yet at this time.

	I agree with you that "Blind" acceptance is a bad thing.  Informed
acceptance, on the other hand is not neccesarily a bad thing.  The conflict
between charles cagle and I came about because of difference in what we thought
most scientists who are in cosmology believe regarding the big bang.  
	One of the problems I have had with Charles Cagle, is what appears
to be a double standard.  He wants hard scientific evidence, but when it
comes to the marketing of his so called "SCYBOLT fusion reactor" he
refuses to put forth the evidence of his experiments.  He gets OUT of
the dilemma by saying that he is interesting in the marketing and selling
of the technology and naturally does not want to reveal the mechanisms.
That's all very good and well, except that I will not beleive a word of this
until he provides proof.  Furthermore, he makes sweeping statments
such as "MOST scientists do not have a desire to find truth" without providing
evidence to support it.  His way out of this was to reply that the statement
is not intended to be scientific, but he knows it to be true.  He knows these
things, so he says, because of his innate desire to love the truth.  
So, my 2nd problem with him was more along the lines of a disagreement between
whether or not one can know what is true through purely subjective means.
The incendiary remarks came out of these conversations.

Quite right.  And if it's an English sonnet, the rhyme scheme is ABAB
CDCD EFEF GG, whereas if it's an Italian sonnet, the rhyme scheme is
ABBAABBA for the first 8 lines, with the rhyme scheme for the last 6
lines at the discrection of the poet.  
An example of an English sonnet (of mine) can be found at

ObMath: It is probably because I am a mathematician, and because
mathematicians appreciate the beauty of elegantly crafted intricate
patterns, that the regular structure of classical verse appeals to me
so much more than contemporary freeverse.  In fact, the classical
poets were well aware of the mathematical nature of their art, and
often used the word "numbers" in reference to their poetry.  For
example, speaking of the poet's ability to find comfort in the
creation of poetry, Donne wrote:
	I thought, if I could draw my pains
	Through Rhyme's vexation, I should them allay;
	Grief brought to numbers cannot be so fierce,
	For, he tames it, that fetters it in verse.
Speaking of the unparalleled mastery of Shakespeare's art, Milton wrote:
	... to the shame of slow-endeavouring art,
	Thy easy numbers flow...
I dare say that to the classical poets, the beauty of poetry was
derived very much from the inherent mathematical structure of
language.  Conversely, for me, the beauty of mathematics comes from
the poetry inherent in the harmonious relationships between symbolic
abstractions.  Both poetry and mathematics seem to possess an
intrinsic intelligence which transcends our own conscious creativity.
Both, in their own way, capture the essence of the universe.
Poetry.  Mathematics.  Same thing.

Lead has a large number of isotopes, some of which are end
prodcuts of radioactive decay of uranium and thorium isotopes
and some of which are left over from the formation of the solar
system.  By choosing a closed system that is unlikely to have
undergone chemical re-equilibration since the rock was formed,
it is possible to measure the relative concentrations of the
parent isotopes (U-235, U-238) and the daughter isotopes
(Pb-206, Pb-207) to calculate the ate of the system.  Zircon
crystals are very resistant to chemical and thermal alteration.
They incorporate uranium more readily than lead when they
crystallize, so the proportion of inherited lead is low.
Measurements are made by crushing the rock, carefully separating
and sorting the zircons, dissolving the zircon separates in
acid, chemically separating the uranium and lead, and analyzing
the isotopic proportions with a mass spectrometer.

The U-Pb-Th system is a rich one (lots of isotpoes), which
provides redundant information that can be used to assess the
reliability of the results on the basis of their internal
consistency.

The biotite age indicates the last time at which the temperature
was high enough to release argon.  This temperature is about 250
degrees Celsius, which is not high enough to cause the rock to
be re-magnetized.

Subject: Re: Mediterranean Basin Flooding Date?
From: "Doug Bailey"
Date: 26 Aug 1996 20:47:51 GMT
Thanks for all the responses.  I think its firmly established that the
Mediterranean basin flooded at least some 5,000,000 years ago.  However, I
am confused.  I have read (though I can not currently recall where)
evidence of massive flooding at Malta.  Some of the evidence consisted of
the remains of various animals found usually in a large plain environment
washed into the recessed cavities of caves on Malta.  A large assortment of
bones have been discovered together as if to say that a variety of species
were washed into the caves by some flood.
I can not remember if human remains were found or not.  Additionally, I can
not remember the dates attributed to the bones.  Though I believe it was
around 10,000 to 20,000 BP.  Was there flooding in the area during the end
of the last Ice Age?  Also, was the Mediterranean significantly lower
during the height of the last Ice Age, and if so to the extent that
now-submerged land areas were then exposed?  I can not find any scholarly
material dealing with any of these subjects.

I for one don't mind reading short, informational material about a new

post was one. 
If we got bombarded with a dozen of these daily, I would want to set up a
sci.geo.petroleum.announce. But the traffic is still pretty light.
BTW you reposted his entire ad for him!

With any measurement there is some error. Perhaps the difference between 
3 and 3.14 would fall with in it. I don't remember seeing real numbers 
in the Bible, only integers. How about you?

Well, going through all of the sonnet forms would have confused the

the definition.

Maybe so, but from my experence, someone who understands/appreciates
one of the two tends to be lax in the other.  But since this is WAY
off-topic for all of the newsgroups this is posted in, the polite
thing for us to do would be to let this thread end here. :-)

The word "yes" is the answer to "what is science" - I see that I'm out of my 
intellectual league, because that makes no sense to me.

Star covered in rock ??
A rock star maybe ??
Not much in the way of nuclear reactions go on in planets of mass <0.01 Msol.
The fact that the core is molten is hardly a reason to call planets stars.
