Roman and others,
I guess I really am slow/dumb. your SG answers maybe too small right now...
Well if you haven't blown anything up...I'm lucky. My calculation has an
error in it from the other day. In the volume part of the equation I left
out
the division by 4 when using the diameter for area. If you use the
radius(1/2
diameter)...then you don't need the 4. The corrected method is below:
***
Then I use a cylinder(round) shaped coffee can for small items, or a
straight
sided bucket for larger items to determine the volume of the object by the
change in height of the water: first without the object and then with the
object. As a slow American I use a stick rule in inches to figure this out.
so it goes like this:
determine weight in OUNCES
Determine the change in volume in the water level by measuring the:
HEIGHT without object first
HEIGHT with the object second
The difference in height in inches is then used to calculate the SG along
with some conversions factors to get it into grams/centimeter cubed.
change or delta Volume = Area of container circle x inches in
height(change)
delta V =(pie or 3.14...)x diameter(inches) squared)x(height change in
inches)/4(Note: this is where I has left out the 4)
delta V is a number in inches cubed
the conversion formula without all the details is as follows:
SG = (object in OUNCES/delta V in inches cubed)x(0.06102/0.03527) = SG in
grams/cm cubed (Note: without the 4 your SG answer would have been 4
times smaller)
0.06102 is the conversion of cubic inches to cubic centimeters
0.03527 is the conversion of ounces to grams.
For the smart users of metric the metric systemthe answer is determined
by the change in volume in cubic centimeters cubed and the weight in grams
or:
Weight in grams/change in Volume in centimetes cubed (now that seems easier
doesn't it) = grams/cm cubed
Bottom line is most rocks have SG of 1.5 to 3, heavier rocks full of iron
like stony meteorites are in the 3 to 5 range, and steel and it's metal
friends like iron meteorites are in the neighborhood of 7 to 8. Silver and
Lead in the 10 to 11 range and gold all the way up near 18 to 19.

[meteorite-list] Astronomers Suggest Comet To Blame for 6th-Century 'Nuclear Winter'
Contact: Dr Derek Ward-Thompson [EMAIL PROTECTED] 029-2087-5314 Cardiff University February 3, 2004 Astronomers unravel a mystery of the Dark Ages Undergraduates' work blames comet for 6th-century nuclear winter Scientists at Cardiff University, UK, believe they have discovered the cause of crop failures and summer frosts some 1,500 years ago - a comet colliding with Earth. The team has been studying evidence from tree rings, which suggests that the Earth underwent a series of very cold summers around 536-540 AD, indicating an effect rather like a nuclear winter. The scientists in the School of Physics and Astronomy believe this was caused by a comet hitting the earth and exploding in the upper atmosphere. The debris from this giant explosion was such that it enveloped the earth in soot and ash, blocking out the sunlight and causing the very cold weather. This effect is known as a plume and is similar to that which was seen when comet Shoemaker-Levy-9 hit Jupiter in 1995. Historical references from this period - known as the Dark Ages - are sparse, but what records there are, tell of crop failures and summer frosts. The work was carried out by two Cardiff undergraduate students, Emma Rigby and Mel Symonds, as part of their student project work under the supervision of Dr Derek Ward-Thompson. Their findings are reported in the February issue of Astronomy and Geophysics, the in-house magazine of the Royal Astronomical Society. The surprising result of the new work is just how small a comet is needed to cause such dramatic effects. The scientists calculate that a comet not much more than half a kilometre across could cause a global nuclear winter effect. This is significantly smaller than was previously thought. Dr. Ward-Thompson said: One of the exciting aspects of this work is that we have re-classified the size of comet that represents a global threat. This work shows that even a comet of only half a kilometre in size could have global consequences. Previously nothing less than a kilometre across was counted as a global threat. If such an event happened again today, then once again a large fraction of the earth's population could face starvation. The comet impact caused crop failures and wide-spread starvation among the sixth century population. The timing coincides with the Justinian Plague, widely believed to be the first appearance of the Black Death in Europe. It is possible that the plague was so rampant and took hold so quickly because the population was already weakened by starvation. ### __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] The Rosetta Space Probe Long Trek To Comet Churyumov-Gerasimenko
http://www.esa.int/export/esaCP/SEMM0JWA6QD_index_0.html European Space Agency Paris, 3 February 2004 Information Note N° 03-2004 ROSETTA N° 1 Getting together in deep space The Rosetta space probe's long trek to Comet Churyumov-Gerasimenko The countdown to Rosetta's rendezvous in space began on 1 March 1997. At the end of February 2004, seven years and not a few headaches later, the European Space Agency (ESA) probe will at last be setting off on its journey to meet Comet Churyumov-Gerasimenko. The long-planned get-together will not however take place until the middle of 2014. A few months after arriving at the comet, Rosetta will release a small lander onto its surface. Then, for almost two years it will investigate Churyumov-Gerasimenko from close up. Dr Gerhard Schwehm, lead scientist for the Rosetta project, explains that, With this mission we will be breaking new ground - this will be the first protracted cometary encounter. The trip to the meeting place in space will certainly be a long one, located as it is some 4.5 astronomical units from the Sun, which translates into something like 675 million kilometres. Rosetta will be on the road for ten years, during which time it will clock up in excess of five billion kilometres. Launch in February 2004 Rosetta will be waved off on 26 February when it lifts off from the space centre in Kourou, French Guiana aboard an Ariane 5 launcher. Shortly after the spacecraft's release, its solar panels will be deployed and turned towards the Sun to build up the necessary power reserves. Its various systems and experiments will be gradually brought into operation and tested. Just three months into the mission the first active phase will be over, followed by final testing of the experiments in October 2004. Rosetta will then spend the following years flying a lonely path to the comet, passing by the Earth, Mars, the Earth and the Earth again. There is no alternative to this detour, for even Ariane 5, the most powerful launcher on the market today, lacks the power to hurl the probe on a direct route to the comet. To get the required momentum, it will rely on swing-by maneuvres, using the gravitation pull of Mars (in 2007) and the Earth (three times, in 2005, 2007 and 2008) to pick up speed. Asteroids for company A change is as good as a rest, and a meeting with at least one asteroid should help break the monotony for Rosetta. The spacecraft will come close to an asteroid at the end of 2008. Asteroids are, it will be remembered, rocky bodies, some as large as mountains, some even larger, that orbit the Sun in much the same way as planets. These 'brief encounters' are a scientific opportunity and also a chance to test Rosetta's instrument payload, says Gerhard Schwehm. But asteroid exploration also serves an entirely practical purpose: The more we find out about them, the better the prospect of being able one day to avert a possible collision. Following a period of low-activity cruising, the probe's course will be adjusted one last time in May 2011. From July 2011, a further two-and-a-half years' radio silence will be observed, and Rosetta, left entirely to its own resources, will fly close to the Jupiter orbit. Link-up in 2014 Finally, in January 2014, the probe will be reactivated and will, by October 2014, be only a few kilometres distant from Churyumov-Gerasimenko. This is where the dream of so many scientists becomes reality. Having deposited its precious lander cargo on the comet's surface, Rosetta will continue to orbit Churyumov-Gerasimenko and together they will spend the next seventeen months flying towards the Sun. Rosetta was built by an international consortium led by Astrium. The lander probe was developed in Cologne under the aegis of the DLR, Germanys space agency, with contributions from ESA and research centres in Austria, Finland, France, Hungary, Ireland, Italy and Great Britain. The comet explorer carries ten scientific instruments. Their job is to draw out the secrets of the comet's chemical and physical composition and reveal its magnetic and electrical properties. Using a specially designed camera, the lander will take pictures in the macro and micro ranges and send all the data thus acquired back to Earth, via Rosetta. This will be our first ever chance to be there, at first hand, so to speak, as a comet comes to life, Schwehm goes on to explain. When Churyumov-Gerasimenko gets to within about 500 million kilometres of the Sun, the frozen gases that envelop it will evaporate and a trail of dust will be blown back over hundreds of thousands of kilometres. When illuminated by the Sun, this characteristic comet tail then becomes visible from Earth. In the course of the mission, the processes at work within the cometary nucleus will be studied and measured more precisely than has ever before been possible, for earlier probes simply flew past their targets. As we will be accompanying Churyumov-Gerasimenko for two years, until the
RE: [meteorite-list] Astronomers Suggest Comet To Blame for 6th-Century 'Nuclear Winter'
I mean, do they offer some PROOF for their theory? A plume is nothing that would have gone unobserved by the eye (left alone a comet exploding in the sky) - and as much as I know, the mini ice age at that time wasn't a global occurence, but rather a european one - at least to my knowledge. There has been a second mini ice age around 1500 in Europe, and this is either attributed to the Maraunder solar minimum or the change of the gulf stream.

There is a book published 4-5 years ago by Baille (title now forgotten by me) that advance the same explanation for the same phenomenon. The bad years of 536-540 AD are a world-wide event. In fact, it seems to have been at its very worst in SW China, where according to the chronicles, the sun was not seen for three years! Crops failed totally, and everything was covered with dust a foot deep. This description has given rise to the alternative theory of these events, which is that there was a volcanic eruption of tremendous size and world-wide effect. The culprit that is advanced is Krakatoa, which did have a massive early episode sometime between 500 BC and 1000 AD, one 10 times bigger than the 1883 episode. However strata from this earlier event are hard to find and none that have been found have been datable with any precision, so it remains only a possibility, but not a proven one. The greatest volcanic event of the last 500 years was Tambora on the island of Sumbawa in Indonesia in 1815, a 13,000-foot volcano that belched f1ame and ash from April 7 to 12, 1815; and rained stone fragments on surrounding villages. It has been estimated that Tambora's titanic explosion blew from 37 to 100 cubic miles of dust, ashes, and cinders into the atmosphere, generating a globe-girdling veil of volcanic dust. This produced The Year Without A Summer world-wide in 1816. For fascinating details, see: http://wchs.csc.noaa.gov/1816.htm. Of course, the effects described in this fascinating piece of history could just as easily have been produced by a insignificant little 150-200 meter comet. At the time (1816), the cause was complete mystery (except to Benj. Franklin, who hypothesized the cause to be volcanic dust). Tambora was not identified as the culprit for almost a century (1913). Sterling K. Webb Bernhard \Rendelius\ Rems wrote: I mean, do they offer some PROOF for their theory? A plume is nothing that would have gone unobserved by the eye (left alone a comet exploding in the sky) - and as much as I know, the mini ice age at that time wasn't a global occurence, but rather a european one - at least to my knowledge. There has been a second mini ice age around 1500 in Europe, and this is either attributed to the Maraunder solar minimum or the change of the gulf stream.

The team has been studying evidence from tree rings, which suggests that the Earth underwent a series of very cold summers around 536-540 AD, indicating an effect rather like a nuclear winter. The scientists in the School of Physics and Astronomy believe this was caused by a comet hitting the earth and exploding in the upper atmosphere. The debris from this giant explosion was such that it enveloped the earth in soot and ash, blocking out the sunlight and causing the very cold weather. This effect is known as a plume and is similar to that which was seen when comet Shoemaker-Levy-9 hit Jupiter in 1995. Historical references from this period - known as the Dark Ages - are sparse, but what records there are, tell of crop failures and summer frosts. The work was carried out by two Cardiff undergraduate students, Emma Rigby and Mel Symonds, as part of their student project work under the supervision of Dr Derek Ward-Thompson. Their findings are reported in the February issue of Astronomy and Geophysics, the in-house magazine of the Royal Astronomical Society. The surprising result of the new work is just how small a comet is needed to cause such dramatic effects. The scientists calculate that a comet not much more than half a kilometre across could cause a global nuclear winter effect. This is significantly smaller than was previously thought. Dr. Ward-Thompson said: One of the exciting aspects of this work is that we have re-classified the size of comet that represents a global threat. This work shows that even a comet of only half a kilometre in size could have global consequences. Previously nothing less than a kilometre across was counted as a global threat. If such an event happened again today, then once again a large fraction of the earth's population could face
