Re: [meteorite-list] Quickie
Pete, James, Stuart, List Long answer to a quick question. 1. The Moon DOES rotate on its axis. If it didn't, we on the Earth would have a slow month-long changing view of every spot on the Moon. There would be no near side and far side. If you were looking at what we call the near side tonight, in two weeks you would be looking at the far side. The sidereal (with reference to the stars, rotation period of the Moon is 27.321582 days. The orbital period of the Moon is 27.321582 days. In a word, the orbit is synchronous. That's relative to the stellar background. The synodic (relative to the Sun) orbital period of the Moon is different, 29.530589 days. In case that puzzles you, the cause of the difference is explained here: http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question32.html 2. James, the strength of the tides is determined by the Moon's MASS, hence its gravitational influence. Given the same orbit, the tides would be the same whatever the period of rotation, 27 days or 27 hours. Now, you may be referring to the fact that the Moon's center of gravity is displaced toward the Earth slightly, and if it rotated rapidly (or didn't rotate at all), it would slightly alter the gravitational pull and the tidal effect from it, but effect would be incredibly small. The center if gravity is only offset about two kilometers! 3. It has been hypothesized that without our large and prominent satellite, humans would have been a much longer time figuring orbital mechanics. Remember it was idly trying to figure out how fast the Moon was falling around the Earth that gave Newton his first push into the theory of gravity while he was back home to avoid the plague while a young student. The Moon's orbit is incredibly complex, full of tilts and wobbles of every kind. http://en.wikipedia.org/wiki/Orbit_of_the_Moon The full calculation of the equation of the Moon's orbit (where it will be at a specific time) is one of the most computationally intensive tasks ever done. Men have devoted their entire working life to it and still not finished the job. The last to do it was E. W. Brown: http://en.wikipedia.org/wiki/Ernest_William_Brown 4. But even IF the Moon had a new, non-synchronous rotation, tidal braking would slowly return it to its old synchronous rotational period. OR, if it had no rotation at all, tidal acceleration would spin it up again to the synchronous period. The full mathematical theory of tidal fiiction and the evolution of the lunar orbit was worked out by the XIXth century physicist George Howard Darwin (Charles Darwin's son). Brief explanation here: http://curious.astro.cornell.edu/question.php?number=124 5. The strength of tidal forces on the Earth's rotation and the Moon's recession (moving away from the Earth) is more dependent on the shape of the continents, the width of the continental shelves, and the depth of the oceans than any other factor. An Earth with many low-lying continents, broad ocean shelves, and shallow oceans would have been slowed to a day much longer than 24 hours by now. And the Moon would have ended up much further away than it is. In the past, the day was shorter and the number days in a year much greater than it is now. I appears that at formation, 4.5 billion yars ago, the year was about 800 days of nearly 12 hours each: ftp://ftp.ecgs.lu/public/publications/jlg/jlg90/JLG90_Denis.pdf 6. Tides are far from simple. In Tahiti, for example, the actual experienced tides are almost entirely a product of the Sun's gravity. You get a good approximation by ignoring the Moon altogether. There's a high tide at noon and midnight and lows at 6 am and pm. Why? http://tahitiexpeditions.typepad.com/travelblog/2010/07/tides-in-tahiti.html 7. We now have a short list of people on this List with nothing better to do on a Saturday night... I suppose especially me who wrote the longest. Sterling K.

Almost never offered !! Erofeev and Lachinov, Russian scientists, first discovered diamonds of cosmic origin in the Novy Urey. In the morning several peasants plowed their field 3 km from a village. The day was gloomy, the whole northeastern sky was covered by clouds. Suddenly a light appeared all around. In several seconds a strong report was heard, like a cannon or explosion. Then came a second, louder noise. With a loud noise a fireball fell to Earth a few meters from the peasants. Frightened, they did not know what to do. They fell to the ground and could not move for a long time. They thought it was a strong thunderstorm, and that thunderbolts were falling from the sky. Finally, one of them, more brave, came to the place where the thunderbolt had fallen, and to his surprise found only a shallow hole. In the middle of the hole a black stone lay half-buried in the soil. (P.I.

Re: [meteorite-list] Quickie
It was science week at an elementary school. A third grade teacher was teaching the young kids in his class about the solar system. He came in early one day and moved all the desks to the side of the classroom on each wall. He proceeded to set up the sun and planets using various sized styrofoam balls on stands that represented our sun, planets and moons. It took several hours to set up and filled the center of the class room. Later that morning, after the children arrived, he walked around explaining the orbits, and how things worked. Afterwards the children could ask questions. One young girl asked how the moon went around the earth. So he grabbed the moon and showed her how it went around the earth. Another young student asked how the earth went around the sun. So with the help of the young girl the asked the first question, he show the earth going around the sun at the same time the moon was going around the earth! It took some coordination! One of the brighter students then asked the questionif all these planets go around the sun, then what does the sun go around?? The teacher looked around the room, paused and said, Good Question! Are we having fun yet? Cheers!

Re: [meteorite-list] Quickie
Jim, List, Whoops! The Sun revolves around the center of our galaxy at about 220 km/sec which suggests a period of about 240,000,000 years. That's the current estimate, although the range of calculated values runs from 225 million years to 250, so the Sun has made 20 orbits so far. Oddly, it's a retrograde (backwards) orbit. What isn't known is the ECCENTRICITY of that orbit. If it's reasonably eccentric, has the Sun plunged down through the Galactic Core region 20 times? The Core is incredibly crowded with stars and dust and molecular clouds and weird sh-..., er, stuff of every kind. It's really crowded in that neighborhood. Look at a picture of a spiral galaxy and you'll see what I mean. The prospect of that particular joyride is a little daunting, at least to me. Every time I read that some geologist or other has detected a 250 million year periodicity in major change on Earth (like orogeny), it bothers me. Now, you know that eight-year-old is going to ask the next question, What does the Galaxy go around? The answer is the barycenter of the Local Group, which is itself in orbit around the barycenter of the Virgo Supercluster, which is itself heading a some good speed toward the Great Attractor, about which we know little... or maybe nothing, except it must be a whopper. If he's the eight-year-old I think he is, he will then ask, Does the Universe go around anything? Sheesh. In 1949, Kurt Gödel published an exact and perfect alternative solution of Einstein's equations in which the Universe rotates (but doesn't have an axis). It also has a number of other truly spooky properties that give me a headache. http://en.wikipedia.org/wiki/G%C3%B6del_metric Since then, others have published other exact and perfect solutions of Einstein's equations all of which show rotation. None of these solutions are testable, at least not so far. But you can cut off the eight-year-old with The universe is everything there is, so there's nothing else for it to go around. Sterling K.

But of course, I want to sell (at least some of them) here in the near future. I figured I can always break these down into smaller part slices. But the brecciation is quite amazing, and I wanted to give people a shot at a full slice, or a near full slice before breaking them down more especially if someone likes the larger mosaic.

Re: [meteorite-list] Show - Final Offer
Hi All, The program's name was changed from the Four Rooms on BBC to the Final Offer here. I was scheduled to film on a Saturday in February in LA and had signed a seventeen page contract. Their producer had seen the press about my finding the 13.7 kilo Stump Spring Nevada record chondrite. Instead, I taked them into presenting my 2.1 gram Nakhla that I have with the collection card and release papers from the British Museum, as I was concerned to sell a meteorite found on public land as it can be prosecuted. I also thought the Martian with the little green men would bring a lot more money. My deal with BLM in Cal/Neva is that I don't sell commercially. Shane, the Chief Enforcement Officer for the Bureau of Land Management in the Mohave doesn't mind us hunting as long as we keep to the restriction on total weight and no selling commercially. They even approve off road operations unless your in the designated restricted areas. Three days before the shoot, Final Four's producer called to say that she had overbooked and didn't have enough time in the day to do everyone, so I was picked to be cancelled because unlike the other presenters, I was driving myself and they wouldn't lose any money having to refund air fares and expenses. I found out later that they typically do this so that they have all the talent they need to cover their butts and can late cancel. Their contract says they can do anything they want. I belong to SAG/AFTRA and had gone to the trouble to get a union waiver and arrange my travel plans and put together a bell jar presentation for the Martian. Pissed me off. Count Deiro IMCA 3536 i was scheduled to appear on this show in the UK last november filming but they changed the schedule like 5 times on me after i bought tickets to london. I bailed, the script kept changing and i stood to lose money, and make nothing. Will be interesting, but sadly like most sows these days, it is scripted and not very realistic.

Hi Friends and Collectors, I have a few updates to my inventory that some of you might be interested in. First, I listed some more pieces of the new weird mesosiderite NWA 6953. There are polished endcuts and uncut fragments ranging in size from 1g to over 5g. I also listed a large number of meteorite-related journals and magazines, including the Journal of Meteoritics from 1974, several recent MAPS journals (2011 and 2012), a Meteorite Magazine (11/2011) and three different Elements Journals (one of these focuses on meteorite impact craters). Buy any 4 magazines or journals and get a free issue of MAPS (your choice). Or, if someone really wants all of these journals, contact me off-list and make an offer on the whole lot of them. Some of you may recall the meteorite maps that my soninlaw makes. His most recent one is a map of the United States with over 100 falls, finds and craters shown. After I announced these maps, some of you contacted me with suggested meteorites to add to the map and to correct a couple of typos. The final map has now been printed and it includes several more locations from Canada and the US. As always, you get 20% off all prices by using the coupon code metlist at checkout. Here are a few new offerings - macros, whole stones, and specimens that are larger than what I usually deal with. The Juancheng stone is especially nice. It is 100% crusted, has subtle regmaglypts, and a nice shape to it. It is really too nice to slice up. So I am hoping it finds a home with a collector who is reading this. The Vaca Muerta specimen has a large round metal nodule in it that makes up about 75% of the specimen, with just a little stony silicate matrix on each side of the nodule. This piece gave me fits while trying to cut it. My small trim-saw doesn't handle irons very well, and this specimen was very difficult to cut. The pictures don't really do it justice.

Re: [meteorite-list] Sutter's Mill TKW Update - Friday May 18
Hi Jeff and List, I completely agree. I guess we should come up with some kind of alternative term for the largest stone from a fall like this. Technically, the main mass was probably the cloud of dust and fine particles that will never be recovered. I think I will take your advice and relabel it as the largest known find. Maybe the real main mass is a 5kg oriented nosecone that is sitting undiscovered under a shrubbery somewhere on a piece of unhunted property.

I don't think this is a reasonable usage. Allende, Murchison, Holbrook, and now this meteorite simply don't have a single main mass. Give Ward credit for the largest known piece. I also want to point out that classifications published in the Bulletin are not official classifications. They are considered by the committee to be authoritative classifications, which means they were judged to be done by people with the proper expertise and their findings were judged to be reasonable. But every classification in the Bulletin is nothing more than a finding made by the listed classifier(s), i.e. the work of one specific person or group.

I was contacted by one of the early finders who informed me that his SM-numbered stone was actually a wrong. It was some kind of tar-coated concrete or asphalt. So that stone was struck from the list and run out of town on a rail. The current unofficial TKW is 432.81 grams. The current unofficial number of finds is 55. The main mass is still Robert Ward's superb 44 gram stone. The official classification on this one is going to come pretty quick - think along the lines of Ash Creek. A specimen from that fall was recovered very early and analyzed and it appeared in the Bulletin within a couple of weeks. I expect this new fall will follow a similar path to publication. The only thing that remains to be seen is what will the official classification type be? CM? CM2? CM3(!), CI? Or..?

Re: [meteorite-list] Quickie
Brilliant, Sterling! I believe you've just written the next verse for Monty Python's Galaxy Song. http://www.youtube.com/watch?v=buqtdpuZxvk http://www.youtube.com/watch?v=buqtdpuZxvk From: sterling_k_w...@sbcglobal.net To: nf11...@npgcable.com; meteorite-list@meteoritecentral.com Date: Sun, 20 May 2012 14:53:01 -0500 Subject: Re: [meteorite-list] Quickie Jim, List, Whoops! The Sun revolves around the center of our galaxy at about 220 km/sec which suggests a period of about 240,000,000 years. That's the current estimate, although the range of calculated values runs from 225 million years to 250, so the Sun has made 20 orbits so far. Oddly, it's a retrograde (backwards) orbit. What isn't known is the ECCENTRICITY of that orbit. If it's reasonably eccentric, has the Sun plunged down through the Galactic Core region 20 times? The Core is incredibly crowded with stars and dust and molecular clouds and weird sh-..., er, stuff of every kind. It's really crowded in that neighborhood. Look at a picture of a spiral galaxy and you'll see what I mean. The prospect of that particular joyride is a little daunting, at least to me. Every time I read that some geologist or other has detected a 250 million year periodicity in major change on Earth (like orogeny), it bothers me. Now, you know that eight-year-old is going to ask the next question, What does the Galaxy go around? The answer is the barycenter of the Local Group, which is itself in orbit around the barycenter of the Virgo Supercluster, which is itself heading a some good speed toward the Great Attractor, about which we know little... or maybe nothing, except it must be a whopper. If he's the eight-year-old I think he is, he will then ask, Does the Universe go around anything? Sheesh. In 1949, Kurt Gödel published an exact and perfect alternative solution of Einstein's equations in which the Universe rotates (but doesn't have an axis). It also has a number of other truly spooky properties that give me a headache. http://en.wikipedia.org/wiki/G%C3%B6del_metric Since then, others have published other exact and perfect solutions of Einstein's equations all of which show rotation. None of these solutions are testable, at least not so far. But you can cut off the eight-year-old with The universe is everything there is, so there's nothing else for it to go around. Sterling K.

A third grade teacher was teaching the young kids in his class about the solar system. He came in early one day and moved all the desks to the side of the classroom on each wall. He proceeded to set up the sun and planets using various sized styrofoam balls on stands that represented our sun, planets and moons. It took several hours to set up and filled the center of the class room. Later that morning, after the children arrived, he walked around explaining the orbits, and how things worked. Afterwards the children could ask questions. One young girl asked how the moon went around the earth. So he grabbed the moon and showed her how it went around the earth. Another young student asked how the earth went around the sun. So with the help of the young girl the asked the first question, he show the earth going around the sun at the same time the moon was going around the earth! It took some coordination! One of the brighter students then asked the questionif all these planets go around the sun, then what does the sun go around?? The teacher looked around the room, paused and said, Good Question! Are we having fun yet? Cheers!

[meteorite-list] Fireball spotted in Peru sky :)))
Hello Listers Arequipa, Peru–On May 17, Thursday, someone shot video of a strange object that looks like a fireball. The strange fireball was seen in the sky in Arequipa, Peru and caused great surprise for onlookers wondering what it was. Strange enough, this isn’t the first incident with fireballs or meteoroids in Peru. In September 2007, more than 600 were reported sick after a meteoroid landed. And in August 2011 a suspected meteor streaked across the sky over the city of Cusco in Peru. http://wtvr.com/2012/05/20/fireball-spotted-in-peru-sky/ Shawn Alan IMCA 1633 eBay Store http://www.ebay.com/sch/ph0t0phl0w/m.html? http://www.meteoritefalls.com/ __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
