Subject: Weight Reduction in Spinning Masses
Date: Fri, 3 Nov 1995 06:04:35 GMT
Recently Hideo Hayasaka and Sakae Takeuchi of the Engineering Faculty at
Tohoku University in Japan have published an experimental result of this
sort. They found that gyroscopes spinning clockwise as seen from above, at
their location, exhibited a decrease in relative mass of 5.07 x 10^-5
and 4.22 x 10^-5 respectively for the two gyroscope configurations studied.
(Weight was multiplied by 1-e where e is the relative factors given above,
if I haven't botched up in my arithmetic.) The effect as plotted in the
paper I saw appears to be perfectly linear to within reasonable experimental
error, thus giving a rotational velocity at which the weight would go to
zero which I made out to be 3.27 MHz (million rotations per second) in the
first case and 3.95 MHz in the second.
That was with CLOCKWISE rotation as seen from above. With COUNTERclockwise
rotation, the same experimental setup showed ZERO EFFECT. Zip. Nada.
Nichts. Nyechevo. You get the idea. For one thing, this result makes it
almost certain that they are NOT dealing with bad lab technique. Not to
mention the fact that they spent nearly a year and a half going over and
over their setup and trying to answer all objections by the reviewers of
their Physical Review Letters paper (it eventually appeared in PRL
(63 2701)). As far as I know, nobody has published a theoretical model
that accounts for these observations. The idea of a physical phenomenon
that appears only in one direction of rotation is rather unprecedented.
I know of only one other mathematical/physical phenomenon that does this,
and I'm trying to understand how the two might be related, but without
success as yet.

Physicist Alex Harvey wrote an article about the
Hayakawa-Taguechi experiment. The article was published in:
Nature, Aug 23 1990, Vol 346 Page 705
You'll also find other references there. Harvey shows
mathematically that an angular momentum vector aligned
antiparallel to the local gravitational field violates the
equivalence principle. He also shows that the path of a
spinning body under gravity need not be geodesic. Here are
two "holes" in GR that seem to account for the behavior of
H & T's gyros. New experiments should be designed to force
the asymmetry to appear, as predicted by theory, rather than
passively leave the results to chance.
There is a dimensional error of Hayasaka and Takeuchi
which CAN be corrected by supplying a quantity that restores
proper dimensionality. In simplest terms, H and T's result
looks like: { deltaN = - (proportionality constant) m w r }
where deltaN is the weight change in Newtons, m is the mass
of the rotor in kg, w is the rotation frequency in angular
units and r is the radius of the rotor in meters. The units
of the missing quantity are radians per second. The rotation,
w, has already been counted. The missing quantity is the
precession, Wp. With clockwise rotation, the vector J
points down the spin axis, while the precession vector,
Wp, points up the spin axis.
Physicist Alex Harvey, writing about H and T's results,
confirmed that there is no (symmetrical) weight gain, no
effect at all, with counter-clockwise rotation, J (up).
In this case, says Harvey, "[J] is parallel to the
gravitational field."

You're catching on. The subject of compound angular momentum, or
internal and external angular momentum, or intrinsic and extrinsic
angular momentum has been a repressed subject for about 2 and half
decades. Add to that list, spherical pendulums, Coriolis effect,
except as applied to balistics and meteorology as used by the US military,
and Shafer's pendulum, that neat little device used as the artifical
horizon of aircraft.

There isn't any that I know of, though back in the late fifties, there
was a fellow named Edward Condon at the University of Colorado who was
fairly proficient on the subject. So much so that he wrote the rotational
dynamics section, called noninertial dynamics at the time, of the
reference "The Handbook of Physics" which he also co-edited (Chapter 5).
I don't recall offhand who the publisher was (Harcourt/Brace?), though
it was endorsed by the American Institute of Physics.
Later, when Mr Condon was the head of the USAF project 'Blue Book', he
labored to supress his own work when the directive was handed down from
the Navy's Turtle Island project.

In the Barnett effect a long iron cylinder, when rotated at high
speed about its longitudinal axis, is found to develop a measurable
component of magnetization, the value of which is proportional to
the angular speed. The effect is attributed to the influence of the
impressed rotation upon the revolving electronics systems due to
the mass property of the unpaired electrons within the atoms.

The Barnett Effect is known to me as the effect of a change in
volume of a magnetic material in response to a change in it's
magnetization strength. If a ferrite material is exposed to a
higher magnetization field (more current through the coil) the
ferritd will change in volume. I was not aware that this has anything
to do with alignment to a spinning axis. For further information about
this aspect of the Barnett effect, see: Ref. Handbook of Magnetic
Phenomena, by Harry S Burk, Van Nostrand Reinhold 1986 Page 262.

Critical Dynamics of Magnets
Authors: Erwin Frey , Franz Schwabl (TU Muenchen)
Comments: Review article (154 pages, figures included)
We review our current understanding of the critical dynamics of
magnets above and below the transition temperature with focus on the
effects due to the dipole--dipole interaction present in all real
magnets. Significant progress in our understanding of real
ferromagnets in the vicinity of the critical point has been made in
the last decade through improved experimental techniques and
theoretical advances in taking into account realistic spin-spin
interactions. We start our review with a discussion of the
theoretical results for the critical dynamics based on recent
renormalization group, mode coupling and spin wave theories. A
detailed comparison is made of the theory with experimental results
obtained by different measuring techniques, such as neutron
scattering, hyperfine interaction, muon--spin--resonance,
electron--spin--resonance, and magnetic relaxation, in various
materials. Furthermore we discuss the effects of dipolar interaction
on the critical dynamics of three--dimensional isotropic
antiferromagnets and uniaxial ferromagnets. Special attention is
also paid to a discussion of the consequences of dipolar
anisotropies on the existence of magnetic order and the spin--wave
spectrum in two--dimensional ferromagnets and antiferromagnets. We
close our review with a formulation of critical dynamics in terms of
nonlinear Langevin equations.

Title: Proximity-induced time-reversal symmetry breaking at Josephson
junctions between unconventional superconductors
Author: Kazuhiro Kuboki and Manfred Sigrist
We argue that a locally time-reversal symmetry breaking state can
occur at Josephson junctions between unconventional superconductors.
Order parameters induced by the proximity effect can combine with
the bulk order parameter to form such a state. This property is
specifically due to the intrinsic phase structure of the pairing
wave function in unconventional superconductors. Experimental
consequences of this effect in high-temperature superconductors are
examined.

Title: Gapless Time-Reversal Symmetry Breaking Superconductivity
Authors: A. M. Tikofsky and D. B. Bailey
We consider a layered superconductor with a complex order parameter
whose phase switches sign from one layer to the next. This system is
shown to exhibit gapless superconductivity for sufficiently large
interlayer pairing or interlayer hopping. In addition, this
description is consistent with experiments finding signals of
time-reversal symmetry breaking in high-temperature superconductors
only at the surface and not in the sample bulk.

Title: On the spin density wave transition in a two dimensional spin
liquid.
Authors: B. L. Altshuler, L. B. Ioffe, A. I. Larkin, A. J. Millis.
Strongly correlated two dimensional electrons are believed to form a
spin liquid in some regimes of density and temperature. As the
density is varied, one expects a transition from this spin liquid
state to a spin density wave antiferromagnetic state. In this paper
we show that it is self-consistent to assume that this transition is
second order and, on this assumption, determine the critical
behavior of the 2p_F susceptibility, the NMR rates T1 and T2
and the uniform susceptibility. We compare our results to data on
high Tc materials.

--------------------------------------------------------------------------
The 4 February 1994 issue of Science magazine has an article
about a new theory of inertia. A recent paper by Bernhard Haisch,
Alfonso Rueda and Hal Puthoff in the 1 Feb 1994 issue of Physical
Review A, based on earlier work by Andrei Sakharov, derives inertia
from quantum electromagnetic vacuum fluctuations. The idea is that if
inertia is due to some strange quantum EM effects, it might be
understood and controlled, and even neutralized.
Haisch is at the Lockheed Palo Alto laboratories, Rueda, at
Cal. State. Long Beach, and Puthoff at the Institute for Advanced
Studies in Austin Texas. Needless to say, this new theory is serious,
but very controversial physics. A test is planned later this year at
the SLAC linear accelerator by exposing a high energy electron beam to
terawatt laser. Keep tuned!
-- John H. Chalmers Jr
--------------------------------------------------------------------------
A recent controversial theory of Austin Institute for Advanced Study
physicist Hal Puthoff and his collaborators Haisch and Rueda appears
to explain gravity as not an intrinsic property of matter but as an
indirect consequence of Maxwellian electromagnetic radiation, namely
that (as earlier suggested by the late Russian dissenter Sakharov)
gravity is a "shadow effect" similar to the Casimir Effect of quantum
electrodynamics. Bass points out that if the Haisch-Puthoff-Rueda
theory is correct then Hodowanec's idea of tapping the earth's gravity
field in some electromagnetic way not hitherto suggested is conceivable.
- Joel McClain
----------------------------------------------------------------------
Puthoff and his collaborators have gone so far as to use SED (Stochastic
Electro-Dynamics) to _explain_ both gravitational & inertial mass and
to show their equivalence, and to derive Newton's F = Ma, and to derive
Mach's principle (without which Einstein admitted that no theory of
gravity could claim to be complete), and to derive Dirac's "cosmological
numerical coincidences" as inevitabilities, and to derive Newtonian
gravity, and to derive the Newton-Cavendish parameter G!!!
-- Robert Bass
-------------------------------------------------------------------------
It is an amazing coincidence that the total Newtonian gravitational
potential energy of any object due to all masses in the universe is
equal in magnitude to its total energy, at least to within a small
factor, considering that this involves an expression involving multiple
factors of the order of 10 to the 40th power.
This was pointed out by Dirac in his Large Numbers Hypothesis, and used
as part of a beautiful illustrative theory by Dennis Sciama [1], in
which he constructs a theory of gravity closely analogous to the
classical theory of electromagnetism, and shows that inertia can be
directly attributed to the gravitational effect of accelerating relative
to the gravitational potential sources of the whole universe (or indeed
of accelerating the whole universe relative to the object, because in
Sciama's theory, the two points of view are equivalent). This theory
is obviously consistent with Mach's Principle (which is effectively that
inertial motion is in some sense relative to the rest of universe).
Sciama's theory is only a simplified approximation, but it is so neat
that it seems likely that some similar principle must apply also within
General Relativity. However, one of its most basic implications is
that the gravitational "constant" G would depend on the distribution
of matter in the universe, which seems to be in direct conflict with
GR. I personally think GR is probably not quite right.
