Azimuthal seismic anisotropy constrains net rotation of the lithosphere
T. W. Becker
18] Anisotropy records past motions, and the preference
of our models for small NRs might be because we had not
considered previous tectonic stages. Hence, I also tested
flow for which the NRs of plate tectonic reconstructions for
the Cenozoic [Gordon and Jurdy, 1986; Lithgow-Bertelloni
et al., 1993] were applied as a simplified shear to the RVV
model. The anisotropy match degraded further compared to
present-day NR, both for the Ekstro¨ m [2001] and Debayle et
al. [2005] maps. This shows that the more recent style of
NR may be preferentially preserved over that further in the
convective past. }}

[comments: NR=> non rotational, RVV=>rotational viscosity variance, and Becker from USC, has thus far answered many questions about physics and social networking.

(1) The physics: the NR plate tectonic model, one of many Becker and others have compared, sub-ducts under other plates, his two figures of the Global patterns of Continents and Ocean plates with-out-of-screen plane directions of movements shown, do give me hits at a conjecture that may link his statement, "NR may be preferentially preserved over that further in the convective time past.".
(2) My research goals , have taken a more defined shape
(after spending two days at the U of Mich Science Library looking at geophysics journals, some five different vendors, and then downloading on my USB giga-stick, as well as taking notes on the back of a Cirriculum VIta of Prof. Liemohn, Atmospheric and Space Science, who is offering a Fall 2008 class Geophysical Electrodynamics):

Earthquake prediction is a world wide subject of work by many, and cooperation is here, Becker has demonstrated this to me, his Internet sites shares almost completely his vital work, his own and that of others with who he has worked.

(3) Further, that other researchers write that the one continent dividing into parts has cycled five times, Becker's Figures 1 and 2 show that Africa may have been previous continent from a prior subduction cycle. Other published data reports that earth's mass may have increased, and this should be related to solar winds, but needs closer examination.

This may seem reaching too far into possible pasts, but the knowledge and understanding it might bring are those that commitment to eduction of all the people, surely a goal of Jeffersonian Democracy expressly stated in USA legal history.

(4) Many researchers write of using computer modeling to assist in analyzing data, seismology with geophysics, as well as quantum particle collisions, so it may be possible to get world wide agreements to shift to saving human lives and health by listing the harms actually occurring and also those presently appearing to drive spending resources on warfare in the name of stopping the use of Weapons of Mass Destructions.
