Thanks for your honesty, kiddietyte. There was a good reason I thought this would catch some people, though I'm not telling what it was. [bIG TEETH]

Nowadays don't we call the "what-the-bleep" the virtual field? It is Lorentz-transformable and so "virtual mass" must be distinguished from "stable states". We admit to being more than seventy percent clueless about why the large forms we observe are as they are, and why the state of evolution indicates expansion beyond the previously expected contraction. Do not expect a quick answer here!

This thread lacks a normal vector and we should all be ashamed. Or pour another beer.

Intellectual momentum, hopefully in a definably correct direction.

Momenta!

Like many of us on our not very best days they have the energies but not the momenta.

I use a coarse file if I have to file piano key lead weights, happily a rare job. What happened with lead and what happened with mercury? What is a "tinker's dam"?

(This letter to my colleague:) SB, I like solstice. I have sat with the mathematics that made me feel stupid half of this year. After casting my spherically (or axially) symmetric electron nearfield and following through the orders of m which are generated whenever you use the metric tensor <<creating the GR stress-energy tensor from the Minkowski tensor>>, it was not clear how to proceed. It is assumed to be of degenerate form, [math]g_{ab} = n_{ab} - 2mk_ak_b[/math] where [math]n_{ab}[/math] is the Lorentz flat-space form, and [math]k_a[/math] is a 4D null vector. In the stationary solution (steady-state) one may say that: [math] k_a=k_0<1, u_1, u_2, u_3>[/math] where the 3-vector is a unit length. Sooooo, in the Schwarzschild solution one sees: [math]k_a =\frac{1}{\sqrt r} <1, x/r, y/r, z/r>[/math] so it is a radial unit vector, no? It's taken a whole year to get here but I finally picture the rotating Kerr forms. It has been shown that the Einstein eqs. yield essentially two relationships which may be bound together in COMPLEX FORM and written as a single Laplacian eq., [math]\nabla^2 \gamma=0[/math]. Brilliantly this is solved by 1/r with the z-variable offset by an imaginary amount. We are solving geometrically the unit vector field, still, though it now has further components. Coordinate systems are flying thick and fast, but we see that the radial component is moderated; there is a z-component going as [math]cos\theta[/math]; there is now a [math]\hat\phi[/math] or azimuthal part also, with [math] sin\theta [/math] dependence. This is nice, isn't it? I did not know what to see in the mess of equations I generated. I stepped back, and wrote them on top of one another, and they are much more simply expressible as only three terms involving this vector field. This is satisfying. I will now investigate whether or not the degenerate form works usefully in spheric coords, or if I should stick to this coord system, actually a mixed Cartesian representation. It was in this form that Kerr wrung the <<exterior>> solution in 1963. ALBERSAWA

If you have the excess draft. Maybe I did not catch the subtlety of the opening question, but the path is clear. For a ballast of some S.G.>1, we account for total volume. Ah, I converge with what Insane Alien said.

It is possible to mistake the carrying of the "1" over to the "thousands" place. Mr.Mongoose thanks for your dramatic blackout. Items like this are not intended for people experienced in developing their inner mental blackboard. As for them, repeat after me, three times, "One smart fellow, he felt smart!"

Cool question. You ought to read my thread in Engineering on 'floating stones'. Yes, you can suspend the mass in the water and displace that much more water. What's the specific gravity of the mass?

I work with a near-field which has no residues at the origin.

Ah, sounds familiar; New York papers. Whaddaya think, 2, 1/2 points for a MATHEMATICAL PHYSICIST?

Obsession. That and roughly ten years, according to Scientific American last year. A few years back my Mom sent a good kid's cartoon like Swansont's, where the nerd was holding a snowball and calculating for 3-4 frames. Coolly, the math was CORRECT! Then he gets creamed.

My polite dictionary describes Saturnalia as a week-long unrestrained celebration.

I have a friend who drives tractor locally. He and I used to tear the place up when we happended to meet at the Cafe for lunch. He actually taught John Wayne to ride horses, and said, yep, he was just like that, he did not talk much. Over lunch I described severe stuttering as a youth. He said, yep, NOW YOU'RE GONNA HAVE TO LEARN WHEN TO NOT TALK.

Shhssshh, don't tell.

What is your answer?

NO PENCILS OR PAPER!!! In your mind's blackboard take 1000. Now add 30. Add another 1000, and then 40 more. Add 20, then another 1000. Further, add 10 and a last 1000. WHAT'S YOUR ANSWER??? . . . . . . . . . . . . . . . . . . . . . . . . .If it's 5000 you have a bad shift register .
