[meteorite-list] Significant digits
Hi Greg, Good old empty precision on a number converted from metric units. 11,000 metric tons = 24250848.8 lbs. The humorous thing is that I seriously doubt the original mass is known to better than a factor of 3, so none of the digits are significant. --Rob __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Significant digits
Thanks for the explanation, Rob. That makes it a lot easier for me to accept. Sometimes claims by scientists mystify me. This was one of those times, but I understand it now. Thanks again. Greg L.

Re: [meteorite-list] Significant digits
Wouldn't it of progressively obtained more weight as it came closer to the surface of the Earth? Isn't it true the higher you climb into the sky the less you would weigh so if true then the opposite must be true! So what was the weight when it exploded, since it was closer to the surface of the Earth as opposed to entering the atmosphere? Hmmm...a little food for thought to factor in to all you geniuses out there.

Re: [meteorite-list] Significant digits
Kilograms are a unit of mass, which is regardless of the force of gravity. Although often spoken of as weight, correctly it should be referred to as mass. Michael in so. Cal.

Re: [meteorite-list] Significant digits
Michael, you are totally correct. Did you notice that the current usage (in MetBull but also in some official scientific papers) is that one always writes total known weight but also main mass ? Is this now fully admitted or tolerated or ...just odd ? I was puzzled with this years ago but soon admitted this practice so that I even use it as such in my collection writeups at least until TKW is one day officially corrected by someone responsible and concerned to TKM Zelimir -- Prof. Zelimir Gabelica Université de Haute Alsace ENSCMu, Lab.

Re: [meteorite-list] Significant digits
Weight is a force, properly measured in Newtons (or some other unit of force). And strictly, your comment should have referred to the acceleration of gravity, not the force of gravity. Of course, mass and weight are related by Newton's Second Law, F=ma. And it is quite true that the acceleration of gravity changes with height, and therefore the weight changes as well, since the mass is invariant (except for the little detail of ablation...)

The ISS Progress 49 resupply ship, which arrived at the station in late October, will depart the rear port of the station's Zvezda service module at 8:01 a.m. EDT, April 15. NASA TV coverage of the undocking will begin at 7:45 a.m. Progress 49 will reenter Earth's atmosphere several days later and burn up over the Pacific Ocean. Progress 49's departure will clear the way for the arrival of the ISS Progress 51 cargo craft. Loaded with more than 3 tons of food, fuel, supplies and experiment hardware for the six crew members aboard the orbital laboratory, Progress 51 is scheduled to launch from the Baikonur Cosmodrome in Kazakhstan at 6:12 a.m. (4:12 p.m. Kazakh time) Wednesday, April 24. NASA TV coverage of the launch will begin at 6 a.m. Progress 51 will take two days to catch up and rendezvous with the space station. It is scheduled to dock at 8:27 a.m. Friday, April 26.

[meteorite-list] AD - Ebay sales ending soon (Fukang and 0.54g shergottite no reserve, Ung-Ataxite Main Mass, Buzzard Coulee endcut and more...)
Hello, this week 96 item on ebay... A Buzzard Coulee crusted endcut, a nice thin etched Fukang, a martian meteorite (0.54g) without reserve price, a 16.58g Tatahouine, a specimen of Nuvvuagittuq paragneiss (4.28Ga, oldest terrestrial rock). And the etched main mass, as an oriented endcut, of the ungrouped iron (silicated ataxite, cobalt-rich) NWA 6167. Etched sections show an ataxitic texture. Under high magnification the metal shows a very fine (1-5 µm) intergrowth of kamacite and taenite arranged into a micro-Widmanstätten pattern.
