Hello Darren, A bad temper and a temper is the same thing ... right?Since Sikhote is crystalline, you need to temper it properly so it doesn't end up fatiguing as shrapnel. The piece obviously got a bad tempering, as it was done too quickly and the back is still somewhat brittle, though the annealing of the metal is clear in the flow-over perimeter where the heat was applied. Nice piece of work with an attitude ... and a great pun by Michael and Jan. Thanks.

Re: [meteorite-list] INNER SOLAR SYSTEM
Hi, All, If you're talking orbits, you have to start with old Isaac. What would he have given to get his hands on one of our bigger computers? The orbit of any one planet depends on the combined motion of all the planets, not to mention the actions of all these on each other. To consider simultaneously all these causes of motion and to define these motions by exact laws allowing of convenient calculation exceeds, unless I am mistaken, the forces of the entire human intellect. ---Isaac Newton, 1687 Isaac was right; it's not a convenient calculation! This three million year calculation was done for all NINE (not eight) planets; this movie just shows the inner system. I would love to see the whole thing animated, but I don't think it's been done. Here's the URL for the original three million year orbit calculation of the solar system: http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1991AJ101.2287Qamp;data_type=PDF_HIGHamp;type=PRINTERamp;filetype=.pdf Before this numerical integration was done, the longest time period calculated for the solar system was only 4400 years! I include the reference on the (very) off chance somebody wants to check it out; it's a bear of a paper. This URL is not the original 3,000,000 year calculation, but an article by the calculators on the calculating problem and some of the implications of these calculations: http://delivery.acm.org/10.1145/32/314166/p1-lake.pdf?key1=314166key2=0568329511coll=portaldl=ACMCFID=CFTOKEN=222 Here's a few chewy quotes: LONGSTOP integrations were not limited by CPU time but by roundoff error[35]. New fourth order mixed variable symplectic (MVS) integrators reduce roundoff error such that a 10 billion year integration of all nine planets is possible with 128 bit precision. So, in theory, we could calculate the entire lifetime of the solar system (in a decade or two)! I don't think anybody's tried it yet! These new integrators were used for an accurate integration of all nine planets and the Earth's spin axis for 3.05 Myr into the past, and future[36,27]-roughly the limit of 64 bit precision. General relativity was included in an extremely elegant way[40]. Among other things, when you calculate backwards, you have to keep changing the mass of the Sun! The solar wind carries mass away from the Sun so that it becomes progressively lighter over long timespans. You have to work out the rate of mass loss and keep adding mass to the Sun as you go back in time! A comparison with the heroic secular perturbation calculation shows remarkable agreement over their common range including the existence of the secular resonance claimed to be responsible for the chaos[27], but all planetary orbits appear to be regular over the 6 Myr interval... Jupiter is the heavy in this drama, the big bumper. Rob asked for the same simulation with Jupiter missing. My first thought is that things would be more regular and less eccentric, but my second thought is, what if the strong influence of Jupiter suppresses influences that, left to themselves, could get out of hand? For example, the Earth and Venus are very close to being in a 5:8 resonance, but seem to have never achieved it. I say they've never achieved it because if they had ever locked into that resonance and stayed undisturbed, the Earth would have pumped up Venus' orbit in eccentricity until Venus' orbit at aphelion would have reached all the way out to the Earth's orbit and big trouble would have ensued! Big trouble... Maybe the heavy hand of Jupiter keeps that resonance from happening? The accuracy of the integrator at a given timestep is increased by the ratio of Jupiter's mass (the biggest kicker) to the sun's mass. Sussman and Wisdom[46] performed a 100 Myr integration on a somewhat special purpose computer that used the potential approximation to General Relativity[SZ], but was otherwise similar to the 6 Myr integration[36]. They found an initial divergence timescale of 12 Myr, but a 4 Myr divergence dominates after 60 Myr. Note: A divergence is when things go whacky or chaotic. It can show up because the calculation is not sufficiently accurate, but that's not the case here. For it to show here suggests a prior time span in which something unexpected has happened which we can't look back through. The divergence time is a mathematical measure of stability, basically, the answer to the question: If things are stable now, how long would it take for this stable system to go all to hell? The answer is: not long. In the way back when, LaPlace determined that all the planetary perturbations were periodic or harmonic and could be represented by the sum of a series of periodic terms. Then, later, Poincare showed that these series never converged and there was no proof of stability. Then, in 1989, Laskar[23] tested the quasi-periodic hypothesis by numerically integrating the perturbations

[meteorite-list] Opportunity: On the Verge of 'Victoria Crater'
http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20060926a.html Press Release Images: Opportunity 26-Sep-2006 [Image] On the Verge of 'Victoria' Once it was more like a distant dream, the ultimate bonus to an already marvelous Martian mission. Now, NASA's Mars Exploration Rover Opportunity is on the brink of the expansive Victoria Crater, a depression that truly makes those on the path to it look like dimples. At about 800 meters (nearly half-a-mile) in diameter, Victoria is five times larger then Endurance Crater. This image from Opportunity's navigation camera is labeled to highlight features of the large crater. Victoria Crater is informally named for the flagship of Ferdinand Magellan's 16th-Century expedition around the world, and many the features of Victoria will be informally named for places visited by that expedition. The feature labeled in dark yellow as Bright Crater is another crater just outside the far rim of Victoria. At 30 to 40 meters (98 to 131 feet) in diameter, the depression is larger than Opportunity's landing site, Eagle Crater. Labeled in bright purple is Duck Crater, a small dimple on the near side of Victoria Crater (the name is used as a placeholder until the team decides if it will name it or not). Other distant craters are labeled in bright blue. On the far right of the image is Kitty Clyde's Sister, a highly degraded crater informally named for a boat in John Wesley Powell's 19th-Century expedition through the Grand Canyon. The science and engineering teams are strategizing on the best way to approach, and possibly enter, Victoria Crater. This image was taken on the rover's 943th sol on Mars (Sept. 18, 2006).

A blue dot indicates Cape Verde and a red dot Cabo Frio. These two points mark the extent of the crater visible from the rover's position on its 945th Martian day, or sol (Sept. 20, 2006), a location it had reached two sols earlier and from which much of this monster depression was still out of sight. The green annotations indicate Duck Bay, a location expected to allow a view to the other side of the crater. A dune, or ripple, is to the left of the crater, right in front of the green dot location. This is where the team initially talked about sending Opportunity for the rover's first view down into the crater. After further consideration, the team opted for a drive to the right of that ripple (south of the green dot) near the rim. The yellow lines that surround and intersect Victoria Crater are used to measure the crater and the distance to the far bays. North is up. Victoria Crater is about 800 meters (half a mile) in diameter.

Re: [meteorite-list] COMCAST problems
My very plain vanilla ISP (they are the local cable and phone company) has been blocked by Comcast as a purported host of spammers twice in the last month and a half. I couldn't send email to people with Comcast addresses. Comcast refused my request to take my ISP off the black list so I called the company. The frustrated tech said Comcast had told them to stuff it. My suggestion--as the folks in the article cited by Darren suggest--is that if you want to receive email, then get a different ISP than Comcast.

Re: [meteorite-list] COMCAST problems
Hello friends with List-related ISP complaints, ISP's (like any utility/monopoly) have got to be the Nemesis of the Internet. A quick review of AOLs history and you can see that Comcast is a pleasurable walk in the park. My suggestion: I think it is the practical answer to minimizing stress from ISP's. It won't allow you the adrenaline rush of telling Comcast (insert your favorite foe), etc. to bug off ... but it will make you independent of them and prepared for the moment you do truly get fed up and dump them because of high prices or billing abuse. 1) Establish an email account on one of the free services (hotmail.com, AIM.com, gmail, etc.) Protect the privacy of your personal information as best as you can. 2) Use MS Outlook Express (free with free IE, easy to use, and convenient anyway if you have more than one email account) 3) Don't use your ISP for any email. They are now a simple commodity to plug into, and don't have you by the throat holding your email address hostage to ISP changes when you decide. 4) Abra Cadabra! You no longer have problems with the Met list. You have any and all of your email in the same place, including the providers that you previously dumped all searchable right in one place. (friendly AOL has a proprietary format to insure you lose your saved email if you leave - there is an effective work around, contact me if you want to know it) If you want a personalized business email address like [EMAIL PROTECTED] and not be just another gmailed yahoo, establish (or use) your website and set it to forward everything automatically to your yahoo, gmail, hotmail, AIM, etc. address. Another option are low fee quality pay forwarding services with IMAP protocol, e.g., http://www.lessig.org/blog/archives/000834.shtml , that have no advertising and expanded mail control functions. You still may need Outlook, Outlook Express, or non-Microsoft nice products like Eudora, Mozilla Thunderbird, etc. Now, when Confast, AOWell, HellSmouth, etc. really go over the line, pull the plug with no stress, hostages or lost email. But don't be hot-headed about it. All ISPs eventually seem to degrade and the grass isn't necessarily much greener on the other side of the fence. Best wishes, Doug Eric wrote: My suggestion--as the folks in the article cited by Darren suggest--is that if you want to receive email, then get a different ISP than Comcast. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Strange feature in Sikhote-alin
Hi All I ran across a strange feature in a Sikhote-alin meteorite. If this was a Stone Meteorite (Chondrite), I would think that it was a chondrule poking out of the surface. Of course this is not a Chondrule. I tried to take good photos but it was difficult to capture the true feel of this feature. Any thoughts on this? http://www.catchafallingstar.com/sa112aa.htm Jim Strope 421 Fourth Street Glen Dale, WV 26038 http://members.ebay.com/ws/eBayISAPI.dll?ViewUserPageuserid=catchafallingstar.com http://www.catchafallingstar.com __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Kilmichael Structure, Mississippi, Revisited
Tomorrow afternoon, David T. King of the Department of Geology, Auburn University, Auburn, AL will talk recent research conducted on the Kilmichael Structure, Mississippi, at this weeks Gulf Coast Assicaition of Geological Societies 2006 Annual Meeting in Lafayette, louisiana. The paper accompanying this talk is; King, D. T., Jr., and L. W. Petruny, 2006, Cosmic impact in the coastal plain of Mississippi? The Kilmichael structure. Gulf Coast Association of Geological Societies Transactions, vol. 56, pp. 341-351. Its abstract states: The Kilmichael structure, a probable impact crater in Montgomery County, Mississippi, is a circular, structurally disturbed feature possessing a diameter of approximately 5.6 mi. A refraction seismic survey reveals subsurface characteristics of an impact structure, including a central uplift, annular graben, and concentric inward- dipping faults. A gravity profile like that of some confirmed impact craters is present. In a key core hole at the structures center, 770 ft of section, consisting mainly of breccias and large intact blocks, was penetrated and sampled. In this paper, we have reinterpreted the sequence of drilled strata as follows (in reverse stratigraphic order): (1) soil and colluvium; (2) post-impact laminated marine sediments; (3) conglomeratic aqueouswashback or resurge deposits of mixed provenance; (4) interbedded impact breccias and target rock blocks, i.e., surgeback deposits; (5) large, deformed and rotated blocks of the Upper Cretaceous Ripley Formation; and (6) interbedded impact breccias and target rock blocks, mainly Upper Cretaceous chalks. The stratigraphic age of this structure is probably late early to early late Paleocene, based on the fossil age of material from the youngest recognizable intact block drilled in the key core hole. The Kilmichael area was in a marginal marine to shallow marine setting at the time of deformation and the drilled stratigraphy is consistent with aqueous or wet-target impact.

Re: [meteorite-list] Meteorite-wrong pics
I sent 4 pictures to Jason Utas who will post them at photobucket.com and send the link to the Met list. Thanks Jason for your help. Please check out the photos when the link is provided and tell me what you all think. I know it's not a meteorite but what can it be?? Dave -- Original message -- From: [EMAIL PROTECTED] I would like to show a picture of what a friend of a friend thinks might be a meteorite but I know we are not permitted attachments in our emails to the list. Any ideas of how I can post a few pictures? The object which this person dug up (on a 20 acre rural plot in Illinois) is very round, 9 1/4 inch in diameter and weighs 110 lbs. That's pretty much the density of iron, 7.87 g/cc or 492 lb/ft3. It's surface is rusted, but it is nearly perfectly round. The rusted surface gives the impression of thumbprints but it is simply rusted. I think it's a cannonball but am not certain that old cannonballs were this size and weighed 110 lbs. I filed off a chink to do a nickel test but so far haven't the right chemicals to do one. Any ideas?
