mass inertia (as opposed to hysteria)
you have both the average density and the angular momentum from the rotation about the pole axis. If the density were concentrated at a mid-level (anywhere between crust and inner core) this would significantly change the angular momentum because it is a function of the moment of inertia. for a uniform sphere the moment of inertia is: I = 2mr2/5 the mass would be the density x volume or m = (d)(4πr3/3) so I becomes I = 2(d)(4πr3/3)r2/5 = 8dπr5/15 now with this formula you can sum up the mass and the moment of inertia for a number of different scenarios, breaking the sphere into shells by calculating {m} and {I} for the inner and outer radii and subtracting the inner values from the outer to get the values for each individual shell, and then summing the total of all the shells. you are faced with the problem of matching the mass and the moment of inertia with different density distributions. good luck. use a spreadsheet.

Re: wheel in a wheel
cosmo writes: Now earth is the uniform sphere here, I gather. On this point I mught ask a question or two. Are we sure it is 'uniform'? No it is not uniform, if you have been reading the other posts there would be no way to get this from my post. You would also not need to have the shells of different density.

trolling
It's mode of behavior usually with connotations of dishonesty in the postion being presented. From http://members.aol.com/intwg/trolls.htm
An Internet "troll" is a person who delights in sowing discord on the Internet. He (and it is usually he) tries to start arguments and upset people. Trolls are utterly impervious to criticism (constructive or otherwise). You cannot negotiate with them; you cannot cause them to feel shame or compassion; you cannot reason with them. They cannot be made to feel remorse. For some reason, trolls do not feel they are bound by the rules of courtesy or social responsibility. Some people particularly those who have been online for years are not upset by trolls and consider them an inevitable hazard of using the net. As the saying goes, "You can't have a picnic without ants." When you try to reason with a troll, he wins. When you insult a troll, he wins. When you scream at a troll, he wins. The only thing that trolls can't handle is being ignored. One technique used by trolls to generate chaos is to pretend to be a well-liked person. On some systems there is nothing to prevent somebody from signing your name to a distasteful message. On other systems the troll may have to be a bit more wiley, perhaps by replacing one character with another. Here are some examples of various spoofing gimmicks that could be used against a person named Brenda Q. O'Really: But that isn't all of the picture. Another aspect that is not addressed here is pretending to be {A} to lure people into a discussion that is set up for the purpose of getting more and more outrageous until the other people get mad or angry -- the troll plays a "gotcha" game. This kind of behavior was typical of {Arkathon} and {Whatever} btw. This is the behavior I suspected on this thread. Note, I am not accusing you of doing this, just that it had that appearance. I frequent another board that does not have monitors and is often the target of troll attacks of all the forms discussed above. This is information to learn and use, eh? It's about honest communication first. This message has been edited by RAZD, 01-25-2005 07:19 AM

Re: detection challenged
cosmo writes: The thing is, when we make assumptions about things like that, that translate into old age reasoning, and teach children the same, it needs to be shown for what it is. Agreed. Especially for all things based on faith eh? We wouldn't want to mislead children on myths and fables would we?

Re: moving on then
The difference in density among the four innermost planets is not significant. The Planets. what about the moons? some are more "significant" than some planets eh?

Re: interpreting a siggy
either trolling or very dense (pretending to be dense is trolling) "siggy" as in signature, as in the block below the short line. If you go into your profile you will see a section where you can enter a signature, and then there are check boxes on the reply window to

Re: interpreting a siggy
no, dense for looking at the arrow and not where it is pointing, for not knowing that "siggy" is slang for signature. ever tried to get a cat to look where you are pointing? but then we are dealing with the concept of density and distribution of mass and the computations needed to make both the mass and the rotational enertia work out ... ever do that calc? with your diamond core? take it as you want, this thread amuses me.

Re: interpretation crystalizing
cosmo writes: Now, what is it about the crystal earth that doesn't match your rotational obsevations? the point is that before you consider talking more about your model you have to show that it is capable of being at least consistent with the known observations. this means you must have a {density\shell} distribution of matter that matches the total mass of the earth and the total rotational momentum of the earth. as noted before these things are sensitive to their distribution from the center at different powers of that distance, so matching them to the known values will require a thorough definition of density by depth. which of course should also be consistent with your model. then we can talk about what in your model creates different predictions than the standard model and see if we can test for these differences that is the scientific logical approach

Re: interpreting a siggy
exactly. they always look at what you're pointing with (in this case the laser light) and not at the object pointed to, which could be another toy.

{geology lab and calculations information}
could you change the subtitile to {geology lab and calculations information}? and it would be interesting to contact them and see the spreadsheet. thanks.
