I didn't see the show you're describing but perhaps they were playing 
"Devil's advocate" [excuse the biblical reference] to highlight a salient 
point.

Doesn't the magnetic field necessitate "Flowing" or "Turbulence"  within 
the core, a result of the Earth's differential rotation?

OK,

A friend and I were watching a show on Discovery or NatGeo
a couple months back. The program I think was about
asteroids, and impacts, perhaps even "How the Earth Was
Made" or another program. Don't really remember

The point is during the show they said very
matter-of-factly on three separate occasions that the
Earth's core was made of three different materials. One
scientist (or narrator I don't remember) said Earth
had a rocky core. Which we laughed at of course because we
all know that the Earth's core is Solid iron right? Then
another scientist confirmed our knowledge and stated what we
already knew. The Earth core is made of SOLID iron. "Of
course we said!" Now that's right... Then not 10 minutes
more into the show another person stated that the Earth had
a molten iron core.

To make matters even more confusing the show went on to say
that the SOLID iron core was surrounded by molten iron with
lighter "rocky" materials "floating" out beyond that OK...
sounded good at the time, but

My question is simple. Which is it? Molten? Solid Iron? or
Solid iron surrounded by molten iron. And if it's the latter
how is this possible? Wouldn't the solid iron core NOT be
solid if it were sitting in the middle of a molten lake of
iron? Does the core cool faster than the surrounding
material, and if so how is this possible considering this
the logic that says an object cools from the outside in.

Now, I'd like to stop there but I just read an interesting
article on National Geographic's website titled "North
Magnetic Pole Moving East Due to Core Flux" here:
http://news.nationalgeographic.com/news/2009/12/091224-north-pole-magnetic-russia-earth-core.html

At the end of the article it flatly states:

"...Wandering Pole -

Geologists think Earth has a magnetic field because the
core is made up of a solid iron center surrounded by rapidly
spinning liquid metal. This creates a "dynamo" that drives
our magnetic field.

Scientists had long suspected that, since the molten core
is constantly moving, changes in its magnetism might be
affecting the surface location of magnetic north"

I don't know about you, but this confuses me just a little
bit...

Can anyone please clear this up for me? And perhaps the
rest of the world? ;)

Thank you for the citation and reference to the Chinese
falls. It is a rather interesting and very useful paper.

Webb also wrote;

"Paul's response suggests that field work

I agree with you that this is a very interesting thought.
It the case of the reported falls that involve just a few
stones, it highly unlikely that much of anything could
be found.

However, in case of certain reported falls, in which
it appears that thousands of pieces might have fell,
I think even after a few hundred years, that there is
a fair chance that there might still be meteorites that
can be found. I suspect, if a person took into account
what geoarchaeologists call "site formation processes"
and used what is known about the geomorphology and
geomorphologic history of the area, a good geomorphologist
/ geologist / geoarchaeology could make specific
predictions as to where any meteorites from a fall
eventually came to rest and where to best look for them.
It is matter of using the enormous amount of knowledge
already gathered about geomorphology, surficial
landscape processes, and "site formation processes" to
predict the best places to look for meteorites deposited
from a possible fall.

Of course after several hundred years, any meteorites found
would likely be too weathered to be of any interest to
collectors. However, I suspect that scientifically useful
information can still be collected despite how badly
weathered the specimens might be. Of course, any search
for such reported falls would not be easy and there would
be no guarantee of success.

Looking at Yau et al. (1994), the reported 1490 fall, in my
opinion, might be a promising candidate for a search for
meteorites because of both the reported number of objects
and the reported size, 1.0 to 1.5 kg, of individual pieces.
Unfortunately, at this time, I cannot determine what the
modern name for Ch'ing-yang, China and its exact location
is at this time given the different and changing ways that
Chinese names have been and are transliterated into English.

Best Wishes,

Paul H.

Reply-To: specialastroopt...@yahoogroups.ca

I created this newsgroup in order to obtain information on special  
optical lenses like surplus military lenses, ultra high speed  
lenses for use in faint meteor recording, direct image on film,  
with image intensifiers, etc. I am especially interested in the  
Super Farron f/0.87 - 72 mm f.l. lens that was used by NASA/LRC for  
a faint meteor spectra patrol back in the 1960/70s. This type of  
lens was used for aero imaging, x-ray imaging, and CRT recording. I  
have the latter which is designed for 4:1 imaging of a CRT screen.  
My question is, can you make this lens focus on objects at  
infinity? Does anyone have any information on this lens type? I  
can't get it to focus on objects at infinity unless I remove one of  
the rear elements. Is this a normal practice or is there another  
attachment lens that will provide good focus at infinity?

Re: [meteorite-list] Meteorite Deaths? Interesting old article-read

2009-12-29 Thread Sterling K. Webb


Hi, Larry, List,


The events quoted by you from John Lewis'
book are open to interpretation.


This you quickly spin to UFO's and I. Velikovsky
in the very next sentence and following paragraph.
Ridiculous. There is nothing like that in Lewis'
book.

Such a lame response puzzles me. I realize that
Lewis' views are not popular with the community.
Never really undestood why. To me he seems
emminently reasonable. Perhaps it is merely
an inevitable consequence of conflict between
those who like (and want to assert) a cozy and
orderly universe with none but minor upsets
and those who point out it just ain't so, bub.

"Open to interpretation"? I don't see it. Are you
telling me that the "monk, several birds, and a
sheep... killed by meteorites" was really a nun, some
squirrels and a goat killed by stones thrown by
hooligans? Or that it never happened? Got a
contemporary reference for that?



Lewis did not make any effort to try to validate
the events...


Lewis was very clear that his was a records search
(of the sort which almost all of historical research is)
of what historians call "primary sources." He does
sometimes finds multiple references to an event,
but that is rare in the Dark and Middle Ages. See the
opening of Chap. 13 of "Rain of Iron and Ice." Not
field work. Paul's response suggests that field work
could be profitable if the site could be located. That
took me by surprise; I assumed too much time had
passed. It's an exciting thought.

Most of the bulk of my post involved the old Chinese
recorded incidents. Lewis took those from the Yau,
Weissman and Yeomans' paper:
   Yau, K., P. Weissman, and D. Yeomans.
"Meteorite Falls in China and Some Related Human
Casualty Events."  Meteoritics 29, 864-871.

The full text is available here:
http://adsabs.harvard.edu/full/1994Metic..29..864Y

If there is any controversy about the Yau paper (in the
sense of articles that dispute the data or conclusions),
I can't find any despite my Googlestorm for "Yau et al.
1994 meteorite.".

Quoted below are a summary and some comments from:
http://farshores.org/ameteo.htm
   "The... study by Yau et al is based upon an in-depth review
of the catalogues and ancient texts that document the fall
of meteorites in China. Their research has found that 337
meteorites were observed... in China between 700 BC and
AD 1920. Given that the area of China is 9.6 million square
kilometres, Yau et al (1994) find that the average number of
meteorite falls, in China, is 0.1 per year per million square
kilometres. [Please note that this is 80 times smaller than
the MORP estimate and that's too small by 3-4 fold, so the
Yau estimate is modest, to say the least. -- SKW]
   One of the most interesting results of the new study was
revealed when a plot of the number of meteorite falls per
century was made. To their amazement, Yau and coworkers
found a distribution which showed two peaks of higher
than expected activity. An enhanced number of meteorite
falls were recorded between circa 1550 to 1750 and from
circa 1840 to 1880. Unfortunately, it is not easy to understand
what the peaks might mean. The completeness of the accounts
is not known, and the observed rate of falls has to be de-biased
for the effects of an increasing population. That is, as the
population increases so the chances of someone observing a
fireball, and the fall of its accompanying meteorite, increases.
   One explanation of the peaks is that they are due to the existence
of meteorite swarms... This idea is not a new one, but it is
controversial. If nothing else, given that the peaks are real,
and Yau et al offer some statistical arguments to suggest that
they might be, they clearly imply that there are long-term
variations in the rate at which meteorites fall to Earth...
   In the course of their investigations, Yau and co-workers came
across seven accounts of meteorite falls in which human fatalities
and injuries were recorded. In AD 616, for example, it is reported
that "a large shooting star like a bushel fell onto the rebel Lu
Ming-yueh's camp. It destroyed his wall-attacking tower and
crushed to death more than ten people." Another account from
1341 reads, "it rained iron in Chin-ning. They damaged crops.
Most of the people and animals struck by them were killed."
The most recent account uncovered by Yau et al relates to a
fall (or April 25, 1915) in which a woman had her arm torn
off at the shoulder. [A twentieth-century Swedish man lost
his arm to a meteorite also; it was buried with him, the arm,
not the meteorite -- S&T]"

On the entire question of pre-scientific historical documents,
the degree to which ancient chronicles may be relied upon
for observations of astronomical events may be gauged by a
glance at this list of papers:
http://hbar.phys.msu.ru/gorm/eclipse.htm


The "Lewis List" or an expanded version of it is widely quoted
on websites from sober to whacky (who add Firestone, who is
whacky, and Baillie, who is not). He's not responsible for that.

[meteorite-list] Questions About 1490 Ch'ing-yang, Shansi Event


Larry wrote:

"For all of his "research" on these falls, Lewis did not
make any effort to try to validate the events beyond his
interpretation of the writings. It has been a long time
since I read the book or talked to him about it."

This brings up some questions about the alleged 1490
falls in Ch'ing-yang, Shansi, China.

1. Are exact citations and translations of the text from
the reports that Lewis interpreted as describing an massive
meteorite fall and thousands of death in 1490 available
anywhere?

2. Has anyone else examined and commented in detail
on the contents of these reports in regard to a possible
meteorite fall and associated deaths in 1490?

Given the nature of the proposed 1490 meteorite fall,
it would be quite fascinating to be able to read the
translations of the primary Chinese text and learn exactly
what is written in them about this event. If there is any
credible information at all in in these reports that supports
such a massive event, it seems like a person could prepare
a publishable paper alone that presents the translated text
concerning what, if anything, happened in 1490, and the
text's interpretation.

Because of the spectacular nature of this hypothesized
event, it seems like more could be written about it then
the short excerpts that I have been able to find.

Yours,

Paul H.

Re: [meteorite-list] Meteorite Deaths? Interesting old article-read

2009-12-29 Thread tracy latimer


The falls you mention seem to be concentrated around the era in the Western 
hemisphere loosely called 'the Dark Ages.'  While I have no reason to doubt 
that the people involved died, possibly even by meteorite, I find it odd that 
so many fatalities happened within a relatively limited time span, and they 
were identified as 'death by meteorite'.  It wasn't until the 17- or 1800s that 
scientists even believed that rocks could fall from the sky.  I'd want more 
proof before I wrote up that CSI report!
 
Best!

[meteorite-list] NASA Chooses Three Finalists for Future Space Science Mission to Venus, an Asteroid or the Moon

2009-12-29 Thread Ron Baalke



Dec. 29, 2009

Dwayne Brown 
Headquarters, Washington

RELEASE: 09-296

NASA CHOOSES THREE FINALISTS FOR FUTURE SPACE SCIENCE MISSION TO VENUS, 
AN ASTEROID OR THE MOON

WASHINGTON -- NASA has selected three proposals as candidates for the 
agency's next space venture to another celestial body in our solar 
system. The final project selected in mid-2011 may provide a better 
understanding of Earth's formation or perhaps the origin of life on 
our planet. 

The proposed missions would probe the atmosphere and crust of Venus; 
return a piece of a near-Earth asteroid for analysis; or drop a 
robotic lander into a basin at the moon's south pole to return lunar 
rocks back to Earth for study. 

NASA will select one proposal for full development after detailed 
mission concept studies are completed and reviewed. The studies begin 
during 2010, and the selected mission must be ready for launch no 
later than Dec. 30, 2018. Mission cost, excluding the launch vehicle, 
is limited to $650 million. 

"These are projects that inspire and excite young scientists, 
engineers and the public," said Ed Weiler, associate administrator 
for the Science Mission Directorate at NASA Headquarters in 
Washington. "These three proposals provide the best science value 
among eight submitted to NASA this year." 

Each proposal team initially will receive approximately $3.3 million 
in 2010 to conduct a 12-month mission concept study that focuses on 
implementation feasibility, cost, management and technical plans. 
Studies also will include plans for educational outreach and small 
business opportunities. 

The selected proposals are: 


The Surface and Atmosphere Geochemical Explorer, or SAGE, mission to 
Venus would release a probe to descend through the planet's 
atmosphere. During descent, instruments would conduct extensive 
measurements of the atmosphere's composition and obtain 
meteorological data. The probe then would land on the surface of 
Venus, where its abrading tool would expose both a weathered and a 
pristine surface area to measure its composition and mineralogy. 
Scientists hope to understand the origin of Venus and why it is so 
different from Earth. Larry Esposito of the University of Colorado in 
Boulder, is the principal investigator. 


The Origins Spectral Interpretation Resource Identification Security 
Regolith Explorer spacecraft, called Osiris-Rex, would rendezvous and 
orbit a primitive asteroid. After extensive measurements, instruments 
would collect more than two ounces of material from the asteriod's 
surface for return to Earth. The returned samples would help 
scientists better undertand and answer long-held questions about the 
formation of our solar system and the origin of complex molecules 
necessary for life. Michael Drake, of the University of Arizona in 
Tucson, is the principal investigator. 


MoonRise: Lunar South Pole-Aitken Basin Sample Return Mission would 
place a lander in a broad basin near the moon's south pole and return 
approximately two pounds of lunar materials for study. This region of 
the lunar surface is believed to harbor rocks excavated from the 
moon's mantle. The samples would provide new insight into the early 
history of the Earth-moon system. Bradley Jolliff, of Washington 
University in St. Louis, is the principal investigator. 


The proposals were submitted to NASA on July 31, 2009, in response to 
the New Frontiers Program 2009 Announcement of Opportunity. New 
Frontiers seeks to explore the solar system with frequent, 
medium-class spacecraft missions that will conduct high-quality, 
focused scientific investigations designed to enhance understanding 
of the solar system. 

The final selection will become the third mission in the program. New 
Horizons, NASA's first New Frontiers mission, launched in 2006, will 
fly by the Pluto-Charon system in 2014 then target another Kuiper 
Belt object for study. The second mission, called Juno, is designed 
to orbit Jupiter from pole to pole for the first time, conducting an 
in-depth study of the giant planet's atmosphere and interior. It is 
slated for launch in August 2011.

[meteorite-list] The Moon on Everest.

2009-12-29 Thread Jim Strope

On May 20. 2009 Astronaut Scott Parazynski summited Mt Everest.  NASA allowed 
him to carry a specimen of the moon brought back on Apollo 11 to the top of the 
world.  The Discovery channel has started airing the third season of Everest, 
Beyond the Limit and Scotts story will air again on the Discovery Channel Dec 
30 at 8pm Eastern US time.  I have seen the segment and it is certainly worth 
watching.

Re: [meteorite-list] Solar-Radiation Heating Effects on 3200 Phaethon


Katsu,
Thank you for the paper. The Abstract alone explains how its possible for 
different parts of an asteroid to undergo substantially different 
metamorphosis,  providing substantially different meteoroids/meteorites and 
the variety in finds, in some meteorites.

Paul:

For all of his "research" on these falls, Lewis did not make any effort to
try to validate the events beyond his interpretation of the writings. It
has been a long time since I read the book or talked to him about it.

Re: [meteorite-list] Meteorite deaths


Grondine asked:

"Has anyone ever thought of going to those fall sites
in China and hunting them? Or doing archeology in
the case of the larger falls?"

I have not heard of anyone attempting to find evidence
of the larger falls. However, that does not mean much
because usually the results of such research when it is
negative (nobody finds anything) is typically not published
simply because either the authors or editors do not
consider such negative results as being significance
enough to publish.

It is a very good question for which I do not have an answer.
