- Your 100,000 = 10eV argument is excellent, pointed, and nicely succinct.
-
- By simply granting the key point for the moment and then examining it a
- bit more closely, a great deal of quantification work might be saved.
- Good intellectual efficiency, I'd say.
-
- Thus I hereby cheerfully defer this (and the 10E6 case) to Dr. Steven Jones.

- Dr. Jones? :)

- P.S to Douglas Morrison -- Thanks for posting your excellent summary of the
- bubble chamber issue. Because I received it as a Cc I never replied,
- but I thought it was an excellent summary of the key points, and also
- doggone interesting item from a purely history-of-science viewpoint.
-
-
- P.P.S - My understanding from a private email is that the polarization of
- sonoluminescence is dipole. Interesting.
-
- The reason for my interest is simply that in my UC proposal (as it now
- exists, having undergone some modifications), the high density in a final
- collapse must by rather simple geometrical arguments lead to some degree
- of organized lateral flow in the surface of the void (assuming that such
- a surface still exists!). These would take the form of what I've called
- "flow cells" in previous emails, although it's not so much a flow as a
- sort of "folding out" of fluid as it enters into a still-well-organized
- surface.
-
- The lowest possible flow cell count would be two, with fluid entering
- two "poles" and converging at an "equator." If you could link the
- rapid longitudinal accelerations to polarized light emission, a dipole
- polarization would be conceivable.
-
- But that would also imply that higher numbers of fluid cells (three, four
- [tetrahedral], etc., should also be possible. A single cavitation with
- a sufficiently sharp inner surface would by such a model begin with a
- large number of flow cells that would rapidly merge together into the
- final (pre-rebound) count of some very small number of cells, two being
- the smallest possible.
-
- If the light emission began prior to the formation of a two-cell, other
- (and probably fainter) polarization geometries might exist on top of
- the dipole signal. I would judge the identification of such three,
- four, or more pole geometries in the luminescence to be a strong
- indication that the collapse has remain well-organized down to very
- small, near-molecular dimensions.
-
- And as always, please note that none of this may have any validity
- whatsoever, since turbulence could set in long before the such low-cell-
- count geometries could ever form. (If things get small enough and remain
- "sharp" enough, though, I stick to my point that simple geometry will
- force the formation of identificable flow cell patterns with simple
- geometrical relationships.)
