Hi everyone - My apologies once again for not yet writing a full thanks you note to everyone from Tucson, but I hope you'll understand... I've already mentioned Mexico Doug and some others, but let me also thank Impactika, Anne Black, and Chladnis's Heirs, for the fine specimens. There's others who I need to thank, but I don't think that this is the place to do it, for reasons which they know.
The reason for this note is that this is important. I hope you all know that meteorites are more dense than their parent bodies. I can't point you to an easy internet site where you may learn this if you don't. Now that this difference in density is ascribed to "porosity", spaces in the parent bodies. It has turned out that the momentum imparted to a parent body when it is hit by a kinetic mass is far greater than the mere addition of moments, due to a jet reaction which occurs when the parent body is hit. This multiple of momentum is called "beta", and it appears to be dependant on "porosity". So how can you get some good estimates of "beta", of "porosity"? I think that some answers to these questions may be gained by studying strew field distributions for the different types of meteorites. Why? Because those strewn fields, which show a small part of a parent body explodes when it hits the atmosphere, are also dependant on porosity. Does this make sense to all of you experts here? good hunting, Ed ____________________________________________________________________________________ Be a PS3 game guru.
