There is a fairly large body of evidence which supports the idea
of a strong relationship, and possibly an equivalent fundamental
source, for electromagnetism and gravitation. Many references to this
effect are contained in this resource list. But for now, let's forget
about the experimental evidence and theoretical ideas which are
presented here, and begin with first principles.
What if our knowledge of physics had evolved differently?
What if no one had ever given a thought to any theory of gravitation,
before we discovered the principles and theories of electromagnetics
and the two nuclear forces. We might have developed some fairly good
theories which unify the "three" forces. We would know that clumps of
matter are held together primarily by electromagnetic forces. And we
would find experimentally that if we separate some of these clumps of
matter, a small force continues to exist which trys to bring them back
together. Would it seem rational to speculate that this force is something
entirely new and completely different from electromagnetics? Would it
not be a great foolishness to invent something new and call it gravity
and claim that it has no relationship with the known forces, and then
write elaborate mathematical theories which describe it solely as geometry?
Or, would it be more rational to see it as what it probably is --
a manifestation of the electromagnetic forces which we already know
to hold matter together?
Could it be that electric charge is a fundamental thing, and inertial
mass is merely a shadow of something primal, and what we know as a
gravitational field is merely the net result of other primary fields?
Geometrize it if you find it useful to do so, but please recognize that
defining gravity as geometry lends no information to the understanding
of its cause.
Of all the forces we know, there is none stronger than a paradigm.

GENERAL RELATIVITY & QUANTUM COSMOLOGY, ABSTRACT GR-QC/9512027
From: kldalton@cs.clemson.edu
Date: Tue, 12 Dec 1995 11:30:30 -0500
Author(s): Kenneth Dalton
Journal-ref: Hadronic J. 17 (1994) 483-501
Hypothesis: The electromagnetic field is the source of gravitation.
This treatment of gravitation is consistent with the quantum theory
of matter, which holds that electric charge (or `generalized
charge') is the most fundamental attribute of matter. Experimental
predictions of the theory include: (1) any massive body generates a
time-dependent gravitational field; (2) there is a linear
correlation between the gravitational red-shift of a stellar source
and the energy of cosmic rays emitted by that source, given by $
{\Delta \nu}/{\nu_0} = energy (eV)/10^{27} $; (3) the maximum energy
of cosmic rays is $ 10^{27} $ eV; (4) this limit is associated with
an infinitely red-shifted stellar object, an ``electrostatic
black-hole,'' at the potential $ c^2/G^{1/2} = 10^{27} $ volts.
Finally, the theory predicts that the gravitational potential near
any charged elementary particle is many orders of magnitude greater
than the Newtonian value.

Geometric Interpretation of Electromagnetism in a Gravitational Theory with
Torsion and Spinorial Matter
Author(s): Kenichi Horie (KEK Japan)
Comments: Ph.D. thesis, 98 pages, LaTeX file, ca 276kB
Possible geometric frameworks for a unified theory of gravity and
electromagnetism are investigated: General relativity is enlarged by
allowing for an arbitrary complex linear connection and by
constructing an extended spinor derivative based on the complex
connection. Thereby the spacetime torsion not only is coupled to the
spin of fermions and causes a four-fermion contact interaction, but
the non-metric vector-part of torsion is also related to the
electromagnetic potential. However, this long-standing relation is
shown to be valid only in a special U(1) gauge, and it is a formal
consequence of the underlying extended geometry.

-- Section 3.7 Non-Inductive Coils
Several authors have suggested that v x B term in the Lorentz
expression should be called into question. Several unverified
experimental results have ever been made. An experiment is
suggested to test one or several of these theoretical views.
This is an area where the experimental procedure is workable
and the outcome could have direct results in the area of inertia
forces.
During the late 60's William J. Hooper put forth an interesting
theory involving the v x B terms dynamic electrical circuits.
There was and is uncertainty as to the exact physical understanding
of the Biot-Savart-Lorentz law and Ampere's law involving the set
of reaction forces. Peter Graneau has studied these expressions.
Hoopers view was that there are three different types of electric
fields due to the distribution of electric field, and two due
to induction.
At the heart of the issue is the connection of the magnetic field
and its source in the charged particles. EM theory is presently
consistent with the idea that spinning magnetic dipoles create
effects indistinguishable from charged particles. There has been
no critical experiment which can disprove whether a magnetic flux
rotates with its source. If it does co-move with its source then
it is logical to assume that a motional electric field in a fixed
reference frame of the current induces a magnetic field. This
concept is likewise consistent with a field-free interpretation
such as Ampere's original laws.

FREE FALL OF ELEMENTARY PARTICLES: ON MOVING BODIES AND THEIR
ELECTROMAGNETIC FORCES, by Nils Rognerud 1994 (nils@ccnet.com)
(available at the elektromagnum web site)
This paper is a review of the problem of the observable action of
gravitational forces on charged particles. The author discusses the
induced electric fields and the sometimes overlooked unique physical
properties. He analyzes several experiments, showing the reality of
the induced electric fields. The current interpretation, based on the
idea of only one electric field, with certain characteristics, is
compared with alternative approaches.
The Hooper Coil:
The author has tested a setup by pulsing strong currents, opposite and
equal, through multiple parallel conductors. The configuration of the
conductors in this type of experiment will cancel the B-fields, while
still producing an Em field, in accordance with Eq. 4.2. This is
similar to an experiment by Hooper (W. J. Hooper), who successfully
predicted and measured the motional electric field - all in zero
resultant B-field.
Interestingly, all of the above experiments can influence an electron
with a zero B-field, in the region of the electron. This has some
profound implications - one of which is that the motional electric
force field is immune to electrostatic or magnetic shielding.
Experimentally, it can be confirmed that the motional electric field
is immune to shielding and follows the boundary conditions of the
magnetic (not electric) field. The only way to shield a motional
electric field is to use a magnetic shield around the source of the
magnetic flux - containing it at the source. These effects are not
startling if one remembers that the motional electric field is a
magnetic effect and that a magnetic field has a different boundary
condition than the electric field.

Barker places radioactive elements inside the sphere of a
Van de Graaff generator, runs it at a negative potential for several
minutes/hours/days -- and finds that the rate of radioactive decay
is extremely enhanced -- with some relationship to the magnitude of
the negative potential.
The principal investigator undertook a series of experiments to test
the "Barker effect" and the "Keller Catalytic Process" in changing the
rate of radioactive decay of heavy elements (elements heavier than
lead, such as radium, thorium, or uranium, all of which are
radioactive). Barker claims that subjecting radioactive materials to
high electrostatic potentials (50,000 volts to 500,000 volts) can
increase or decrease the rate of radioactive decay, with short
exposures of the high voltage capable of inducing erratic decay rates
which slowly return to normal over a period of weeks. Keller claims
that subjecting radioactive materials to the high heat and fusing
reaction of a chemical process (Keller Catalytic Process) can
eliminate the radioactivity completely.

Otis Carr's work involved counter-rotating charged discs that

relation the the earth's rotational speed and became activated by
free energy from space. Maybe he did have something."
-- James E. Cox
Carr's work is similar in some respects to Hooper's inventions. In both
cases, an anti-gravitational effect is reported to result from equal and
opposite electric currents. Furthermore, one of Hooper's embodiments, the
pancake coil, has an uncanny resemblance to the gravitational shielding
experiments which were recently conducted in Tampere Finland (1992 and 1995).
Except that in the Tampere experiments, the equal and opposite current is
generated in a superconductor disk by way of the Meissner effect. Will we
soon begin to recognize value of the discoveries that Carr made nearly 40
years ago, and Hooper made over 25 years ago?

Experiments were conducted to test assertions from Patent 3,610,971, by W.J.
Hooper that self-canceling electromagnetic coils can reduce the weight of
objects placed underneath. No weight changes were observed within the
detectability of the instrumentation. More careful examination of the patent
and other reports from Hooper led to the conclusion that Hooper may have
misinterpreted thermal effects as his 'Motional Field' effects. There is a
possibility that the claimed effects are below the detection thresholds of
the instrumentation used for these tests.
CASI Accession Number: N95-28893
I have two problems with the methodology used by the NASA scientists in
the above experiment.
First -- The amount of ampere-turns used in the NASA experiment was
substantially lower than the amount used by Hooper. Hooper found that
his effect increased in proportion the square of the current. If you
were motivated to verify that the Hooper effect exists, would you not
try to conduct the experiment with MORE current, rather than less?
Second -- NASA conducted it's tests by energizing the coils and making
measurements in an immediate on-off mode, rather than letting things
run for a while as Hooper did. NASA's reason for doing this was to
avoid errors due to thermal effects. This makes sense. But what does
not make sense is that if you are trying to verify an original experiment
and you make changes, you have an obligation to also conduct the
experiment in it's original mode. To do otherwise is bad science.
But what could be wrong with testing things in an immediate on-off mode?
Well, it can be seen in other experiments that a gravitational effect
sometimes results from macroscopic spin alignment of the quantum
angular momentum of a large number of microscopic particles. It has
been demonstrated in other experiments that it takes time for these
particles to come into alignment. For example in the inventions of
Henry Wallace it sometimes took minutes for the "kinemassic" gravito-
magnetic field to fully manifest itself. The reason that it takes time
for particles to come into alignment, could be much the same reason that
it takes time to permanently magnetize a magnet. Wallace found that the
"kinemassic" effect occurs with elemental materials which have a component
of unpaired spin in the atomic nucleus. This includes all common isotopes
of copper, which of course is the material used in Hooper's coils.
Incidently, NASA essentially has an economic monopoly in the lucrative
market for microgravity materials research.
-- Robert Stirniman
------------------------------------------------------------------------
The Hooper effect can be readily demonstrated in the "Two Moving
Magnets Experiment". In this experiment, magnetic flux is provided by
equal strength opposite pole magnets, moving uniformly in opposite
directions. The induced motional electric field that is generated
in a conductor, is found to be twice that which would result from
a single magnet, while remarkably, the sum of the magnetic B field
is zero. This experiment is easy to setup and verify in any electronics
laboratory with a pair of magnets, a wire, and a voltmeter. In fact,
you may wrap the conductor, in electrostatic or magnetic shielding,
and find the same result.

Apparently, there are some VERY interesting clues to the nature of the
universe that are related to the phenomenon of SPIN. It might get very
interesting if someone were to make a project of assembling in one place
all the information that has been observed, alleged, suspected, or
speculated about concerning unexpected effects related to spin, along
with all the traditional Newtonian results, stir, add some seasoning,
and see what comes out.
For example, in quantum mechanics, if you want to measure the spin axis
of an electron, you do an experiment in which you ASSUME an axis, make a
measurement of the correlation (the dot product) of that axis with
the actual axis of spin for that electron, and theory says you can
determine at least how close your guess was.
It was a major surprise for the first expermienters with this to find that
the guess was always right: whatever spin axis you assume turns out to be
correct, exactly dead accurate. You must be a VERY good guesser. Out of
this experimental result came the concept of "isospin". Which in itself
is kind of weird in that objects with zero radius can still exhibit spinx.
But I find the idea that the spin is wherever you guess it might be to be
even weirder and to need a better model that predicts this result.

Gravitational Field of a Moving Spinning Point Particle,
by Jaegu Kim, 7 pages,
The gravitational and electromagnetic fields of a moving charged
spinning point particle are obtained in the Lorentz covariant form
by transforming the Kerr--Newman solution in Boyer--Lindquist
coordinates to the one in the coordinate system which resembles the
isotropic coordinates and then covariantizing it. It is shown that
the general relativistic proper time at the location of the particle
is the same as the special relativistic one and the gravitational
and electromagnetic self forces vanish.

of the Korean Physical Society, Vol 27 No 5, Oct 94, Pages 484-492
Jaegu Kim, "Gravitational Field of a Moving Spinning Point Particle",
Journal of the Korean Physical Society, Vol 27 No 5, Oct 94, Pages 479-483
In the above papers, Dr. Kim derives solutions for the Einstein-Maxwell
equations for: a charged massless point particle, a point particle having
mass but no charge, a point particle having mass and charge, a massless
point particle with charge and spin, and finally -- a point particle having
charge, mass, and spin. He determines that there is a region of space
around a charged spinning mass in which the gravitational force is negative.
The ability to generate a negative gravity effect may come as no surprise
to experimenters who have worked with Bose-Einstein condensates, superfluids,
or superconductor material in which the angular momentum of quantum level
particles can become aligned along a "macroscopic" spin axis. And it is
probably also not a surprise to those who have looked at devices such as
the inventions of Henry Wallace, in which a macroscopic body is mechanically
spun at high speed in order to cause a "kinemassic" gravito-magnetic field
due to spin alignment of the nucleus of elemental materials having an odd
number of nucleons (un-paired spin).

Is anyone familiar with the experiments in Tampere Finland, by
Podkletnov et al on weak gravitational shielding from a Meissner
levitating, rotating disk of high-Tc superconducting material?
The paper is: E. Podkletnov and R. Nieminen, Physica C 203 (1992) 441.
E. Podkletnov and A. D. Levit have another paper now, a Tampere
University of Technology report, January 1995 (Finland),
the experiment having being repeated (I assume no one
believed it the first time?).
In the 1st experiment a 5 g sample of silicon dioxide was found
to loose around 0.05 % of its weight when placed at a distance of
15 mm from the SC disk. The SC disk had diameter 145 mm and thickness
6 mm. Under rotation of the disk the effect increased up to 0.3 %.
In the 2nd experiment samples of different composition and
weight (10-50 g) were placed at distances of 25 mm to 1.5 m from
the disk. The mass loss went as high as around 2 %.
I found out about this through a theoretical preprint by Giovanni
Modanese, a Von Humboldt Fellow from the Max Plank institute. The
preprint no. is MPI-PhT/95-44, May 1995. A colleage got it from
hep-th@babbage.sissa.it, paper 9505094. Modanese thinks that it is
something to do with the bose condensate from the SC interacting
with the gravitational field. He uses some non-perturbative quantum
theory on the Regge lattice to attempt to understand the effect.
Must be a little bit like explaining cold fusion with the standard
tools - couldn't be done. We all know what happened to cold fusion
but at the time a professor from my department said in a public
lecture that the product of the believability and the potential
importance if true was of order 1.

Theoretical analysis of a reported weak gravitational shielding effect
Author: G. Modanese (Max-Planck-Institut, Munich)
Report-no: MPI-PhT/95-44 May 1995
Under special conditions (Meissner-effect levitation and rapid
rotation) a disk of high-Tc superconducting material has recently
been found to produce a weak shielding of the gravitational field.
We show that this phenomenon has no explanation in the standard
gravity theories, except possibly in the non-perturbative quantum
theory on the Regge lattice. More data, and independent repetitions
of the experiment are however necessary.
ABSTRACT SUPR-CON/9601001
From: Modanese Giovanni
Date: Wed, 17 Jan 1996 21:54:45 +0100 (MET)
Updating the analysis of Tampere's weak gravitational shielding experiment
Author: Giovanni Modanese
Report-no: UTF-367/96
The most recent data about the weak gravitational shielding produced
in Tampere by Podkletnov and coworkers through a levitating and
rotating HTC superconducting disk show a very weak dependence of the
shielding value ($\sim 1 \%$) on the height above the disk. We show
that whilst this behaviour is incompatible with an intuitive
vectorial picture of the shielding, it is consistently explained by
our theoretical model. The expulsive force observed at the border of
the shielded zone is due to energy conservation.
-------------------------------------------------------------------------
NASA is conducting experiments similar to the anti-gravity shielding
experiments done in Tampere Finland. A scientist named Ning Li at the
University of Alabama Huntsville, is reported to be consulting with NASA.
She has written some interesting articles about the relationship between

I haven't had the opportunity to read the articles by Drs. Li and Torr,

interesting comment --
" a detectable gravitomagnetic field, and in the presence of a
time-dependent applied magnetic vector potential field, a
detectable gravitoelectric field could be produced"

There is also some information about Dr Ning Li at:

Dr Li is with the Applied Materials Lab at the University of Alabama

environment -- a peculiar coincidence, or maybe not, with the writing
of physical theories about how to produce anti-gravity in the laboratory.
Here's an unusual article from the website.

Can gravity be 'made' in the laboratory?
A theory that might lead to the creation of measurable manmade
gravitational fields has been developed by physicists at UAH.
If the theoretical work is borne out in the laboratory, it will prove
that physicist Albert Einstein was correct in predicting that moving
matter generates two kinds of gravitational fields: gravito-magnetic
and gravito-electric. The 'artificial' gravitational field would be
generated inside a container made of a superconducting material, said
Dr. Douglas Torr, a research professor of physics and director of
UAH's Optical Aeronomy Laboratory. "I think we can at the very least
generate a microscopic field ..." If Einstein was right, the amount of
gravito-magnetic energy produced by an object is proportional to its
mass and its movement, explained Dr. Ning Li, a research scientist in
UAH's Center for Space Plasma and Aeronomic Research. To create the
artificial gravitational fields, Torr and Li propose placing a
superconducting container in a magnetic field to align ions that are
spinning or rotating in tiny circles inside the superconducting
material. Their theory predicts the existence of ionic spin or
rotation in a superconductor in a magnetic field.

There are persistent rumors among UFO-buffs that NASA already has an
operating microgravity chamber, located in Houston TX and/or Huntsville AL.
One person, Robert Oechsler, reports that he has personally been inside
NASA's antigrav chamber. But, that's another story. For more info, see
the books "Alien Contact" and "Alien Update" by Timothy Good.

Title: Gravity as a coupling of two electromagnetic fields
Author: Vu B Ho
A discussion on a possibility to represent gravity as a coupling of
two equal and opposite electrogmanetic fields. Classically the
existence of equal and opposite electromagnetic fields can be
ignored altogether. However, the problem can be viewed differently
if we want to take into account possible quantum effects. We know
that in quantum mechanics the potentials themselves may be significant
and they may determine the dynamics of a particle in a region where
the fields vanish. (Aharonov and Bohm 1959, Peshkin and Tonomura 1983)
AN EXPERIMENT TO TEST THE GRAVITATIONAL AHARONOV-BOHM EFFECT

The gravitational Aharonov-Bohm (AB) effect is examined in the weak-field
approximation to general relativity. In analogy with the electromagnetic AB
effect, we find that a gravitoelectromagnetic 4-vector potential gives rise
to interference effects. A matter wave interferometry experiment, based on a
modification of the gravity-induced quantum interference experiment of
Colella, Overhauser and Werner (COW), is proposed to explicitly test the
gravitoelectric version of the AB effect in a uniform gravitational field.

I recommend you get a copy of Aharonov and Bohm's classic paper
"Significance of Electromagnetic Potentials in the Quantum Theory"
published in The Physical Review in 1959. One of the important things
that Aharonov and Bohm did was to demonstrate that the electromagnetic
potentials are richer in properties than the Maxwell fields. The field
is an artifical mathematical construct from which emerges the whole idea
of a continuum. When you can wean yourself of this intellectual crutch
you will be ready to do real physics. Both GR and QM are addicted to
the same falsehood.
-- Charles Cagle
In the Aharonov-Bohm effect it has been determined theortically and
experimentally that there is a measurable effect on a charged particle
due to the electromagnetic vector potential. Which of course would be no
surprise, except that the effect occurs even in areas of space where
the value of the classical electromagnetic fields vanish. A quantum
phase shift, detectable via particle interferometry, is found to occur
due to the magnetic vector potential A. The effect on a charged particle
occurs in regions which are completely shielded from classical
electromagnetic fields.
A dual of the Aharonov-Bohm effect is the Aharonov-Casher effect,
where it is shown that measurable effects of spin-precession of a
particle's magnetic moment can occur due to the electric potential,
even in areas of space where the classical electrical field is
completely absent.
----------------------------------------------------------------------
Prior to the revolutionary paper by Aharonov and Bohm in 1959, the
importance of the electomagnetic potential and related interferometry
effects, was suggested in articles by Edmund Whittaker in 1903 and 1904.
And, what is now known as the Aharonov-Bohm effect, was explicitly
identified in an earlier paper on electron optics by Ehrenberg and
Siday in 1949.
E.T. Whittaker, "On the partial differential equations of mathematical
physics," Mathematische Annalen, Vol 57, 1903, pages 333-355.
In this paper Whittaker demonstrates that all scalar EM potentials have
an internal, organized, bidirectional EM plane-wave structure. Thus
there exists an electromagnetics that is totally internal to the scalar
EM potential. Since vacuum/spacetime is scalar potential, then this
internal EM is in fact "internal" to the local potentialized vacuum/
spacetime.

E.T. Whittaker, "On an expression of the electromagnetic field due to
electrons by means of two scalar potential functions," Proceedings of
the London Mathematical Society, Series 2, Vol 1, 1904, pages 367-372.
In this paper Whittaker shows that all of classical electromagnetics
can be replaced by scalar potential interferometry. This ignored paper
anticipated the Aharonov-Bohm (AB) effect by 55 years, and drastically
extended it as well. Indeed, it prescribes a macroscopic AB effect that
is distance-independent, providing a direct and engineerable mechanism
for action-at-a-distance. It also provides a testable hidden-variable
theory that predicts drastically new and novel effects.
-- Tom Bearden
W. Ehrenberg and R. W. Siday, Proc. Phys. Soc. London, B62, 8 (1949)
Ten years earlier than Aharonov and Bohm, Ehrenberg and Siday
formulated the science of electron optics by defining the electron
refractive-index as a function of electromagnetic potential. Near the
end of their paper, they discuss "a curious effect", which is exactly the
AB effect. On the two sides of a magnetic flux, the vector potential has
different values. This means a different refractive index for two
geometrically equivalent paths. This difference in refractive index
would cause an observable phase shift.

Effects of potentials on charged particles exist even in the region
where all the fields (and therefore the forces on the particles) vanish,
contrary to classical electrodynamics. The quantum effects are due to
the phenomenon of interference. These effects occur in spite of Faraday
shielding. The Lorentz force does not appear anywhere in the fundamental
quantum theory, but appears only as an approximation that holds in the
classical limit. In QM, the fundamental physical entities are the
potentials, while the fields are derived from them by differentiation.

Potential Effect: Aharonov-Bohm Effect of Simply Connected Region
Author: Jun Liu
Comments: Prediction of a new effect. Numerical estimate given for
experimental verification. The referees disagree with each other on
the existence of this effect.
We study a generalization of Aharonov-Bohm effect, the potential
effect. The discussion is focused on field-free effects in simply
connected region, which obviously can not have any local field-flux.
Among the published discussions about this kind of effects, it is
generally agreed that this kind of effect does not exist due to
gauge invariance. However, there are also opinions that this effect
is a trivial variation of Aharonov-Bohm effect and therefore there
is no need to check its existence. To my knowledge, it has never
been tested. My first goal here is to supply enough theoretical
reason to motivate the experimental test of this effect. I start
with an intuitive derivation, then I introduce a wave-front theory
as a theoretical consideration. Logically, the existence of
potential effect implies the existence of the AB effect, but not
vice versa. The purpose of this paper is to provide a physical
connection in the opposite direction.

The Real Significance of the Electromagnetic Potentials
Author(s): J`un L'iu
The importance of the potential is revealed in a newly discovered
effect of the potential. This paper explore the same issue
introduced in quant-ph/9506038 from several different aspects
including electron optics and relativity. Some people fail to
recognize this effect due to a wrong application of gauge
invariance.
In the above two papers, Dr Liu proposes a theory of the electromagnetic
potential which is a radical extension of the well known Aharonov-Bohm
effect. In the second paper he is barely able to contain his frustration
about repeated publication rejections over the last four years from
leading physics journals. He provides a theoretical foundation for his
potential theory, as well as some relatively straight forward suggestions
for experiments which might confirm the theory. But there is an enormous
problem. Liu's theory violates the concept of invariance of physical
parameters under an electromagnetic gauge transformation. Electromagnetic
gauge invariance is a cornerstone in the foundation of quantum theory and
QED, and it is also part and parcel linked with the dogma of light speed
invariance. In other words, heresy.
The AB effect is invariant under an electromagnetic gauge transformation.
While a phase-shift occurs in the AB effect, it can be identified only
over a closed path and is impossible to identify with any specific
"local" region of space. Furthermore, in the AB effect, there is no
interaction relating to a transfer of energy or momentum. Maintaining
the idea of gauge invariance is a little harder to do in the Aharonov-Casher
effect, but it can be accomplished by "gauging away" the physical effects
of magnetic spin precession by using a combination of factors from the
classical Maxwell fields along with the electromagnetic potential. It
has the look of an elaborate parlor trick, but so does most of QED.
Liu's theory predicts that the electromagnetic potential acts like
a kind of "refractive index" to wave propogation, and is similar in
some respects to what was predicted in the earlier paper on electron
optics by Ehrenberg and Siday in 1949. The result is that in some
circumstances an electromagnetic potential causes a change in wavelength,
and in other circumstances causes a change in phase (AB effect). An effect
on wavelength would be manifested as a change in the envelope of the
interference pattern, rather than merely a shift in the pattern. In Liu's
theory an exchange of energy and momentum becomes possible. His theory
is relatively easy to test and verify, but oddly or not, no one has yet
done so. Maybe because we already "know" it can't be true?
One interesting prediction of Liu's theory is that electromagnetic
potential will result in time dilation. He doesn't appear to be
aware that there is already experimental evidence that this occurs.
See references to inventions and experiments by people such as Saxl,
Barker, and Keller, which demonstrate time dilation in an electric
potential. Time dilation can be viewed equivalently as a shift in
wavelength. Liu wishes for someone to conduct an experiment to test
for a change in wavelength by using a quantum interferometer. A fine
idea. But what about those experimenters who have already measured
this effect with a clock? Also see a variety of references here to
theories and experiments which relate the scalar electric potential
to the gravitational field, and time dilation is a well know, and
experimentally verified, prediction of general relativity.
The Aharonov-Bohm effect has sparked a revolution in physical thought.
There are a variety of new ideas and experiments, such as verification
of Liu's theory, which could soon begin to fan it to a flame. When the
flame becomes sufficiently illuminating, watch the political scientists
begin to scramble for a comfortable seat nearer the fire.

Time out for a summary.
. Hooper, as well as Carr, Rognerud, Jefimenko, et al, find that a
electromagnetic effect which is not shieldable, and hence difficult
to distinguish from gravitation, results from equal and opposite
electric currents (dipole-current), and that a similar effect can
also be generated by a moving magnet or a moving electric current.
. Recent experiments in Tampere Finland, discover a gravitational
shielding effect from a levitated rotating superconductor disk.
This is similar in some respects to Hooper's invention, with the
equal-and-opposite electric current being generated in a superconductor
disk via the Meissner effect.
. Sansbury, Volkov, Brown, Teller, Blackett, Zollner, et al, provide
theoretical arguments as well as some experimental indications that
equal-and-opposite electric charge (dipole-charge) is similar, or
equivalent, to a static gravitational field. And that alignment of
electric dipoles in matter and in vacuum polarization, can result in
a force which is not shieldable, and not easily distinguishable from
gravity. Conversely, it is well know that a gravitational field, an
acceleration, or a mechanical force, causes a dipole moment (polarization)
to occur within a dielectric material.
. Wallace, Laithwaite, Barnett, et al, discover that gravitational
and electromagnetic field effects occur due to alignment of the
microscopic spin of quantum particles with the angular momentum
spin axis of a larger macroscopic body.
. Aharonov and Bohm discover that an effect can occur on an electrically
charged particle due to the magnetic vector potential, in regions of
space where the classic Maxwell fields vanish. Originally -- on the
outside of infinitely long solenoid coil (with the magnetic field
cancelled by equal-and-opposite currents). Others have conducted this
experiment using a toroidal coil coated with superconductor material
(generating an equal-and-opposite current) to cause the Maxwell magnetic
field to vanish. A similar effect, Aharonov-Casher is disovered to
occur due to the electric scalar potential, in regions of space where
the Maxwell electric field vanishes.
. Whittaker, and Eherenberg and Siday, have written theories which
are precursors to Aharonov-Bohm, suggesting that the electromagnetic
potential is a far richer and more fundamental thing than the
Maxwell fields. The classical Maxwell fields are regarded as
artifical abstractions. We can also note that Maxwell's theory
itself, was originally much richer in variables (20 equations and
20 unknowns), before it was simplified by Gibbs and Heaviside,
to the vector formlation which we know as "Maxwell's" equations.
. Vu Ho authors a recent paper suggesting experiments relating the
electromagnetic potential and the Aharonov-Bohm effect to gravitation.
And in a more recent paper, using the mathematics of differential
geometry and general relativity, Dr Ho demonstrates that gravity can
be expressed mathematically as a coupling of two equal-and-opposite
electromagnetic fields.
. Jun Liu authors recent papers suggesting that the electromagnetic
potential is of paramount importance. Liu's theory predicts that "local"
effects can result from the potential in regions where the Maxwell
fields vanish -- a violation of the theory of invariance under electric
gauge transformations. Liu theory predicts that time dilation will
occur in an electric potential. Saxl, Barker, and Keller have conducted
earlier experiments which demonstrate time dilation in an electric
potential.
. Ning Li, a consulting scientist to NASA's Marshall Space Center,
who we might presume to know something, authors papers about the
relationship of gravito-electric and and gravito-magnetic forces to
the electromagnetic potential, and methods for generation of
gravitational effects with superconductor material. According to
Dr Li -- "a detectable gravitomagnetic field, and in the presence
of a time-dependent applied magnetic vector potential field, a
detectable gravitoelectric field could be produced."
How many clues do we need? Equal-and-opposite electric sources (dipole-
charges and/or dipole-currents) appear to effect the electromagnetic
potential in ways which are indistinguishable from gravitation. And
you know what they say about things that look like a duck.
The net sum of equal and opposite electromagnetic vectors is a zero
vector, but it is NOT the same situation as no vector. For skeptics and
diehards who are still having a hard time accepting the idea of electro-
gravitics, here's a simple experiment. Stand on a train track between
two locomotives which are pushing on you with equal force in opposite
directions. You will exhibit no net motion. None the less, you may soon
begin to notice that something important is happening.

article titled "Towards Flight without Stress or Strain...

Many documents on Gravitoelectrics/Electrogravitation refer back
to the 1952 Project Winterhaven. That project is said to contain
information on a Mach 3 Combat Disc. Also, have any records related
to other Projects with Mr. T.T. Brown been produced. I have seen his
Lab notes 1 - 3 - 4. I was looking for 2 - 5 & 6. Also, the Bahnson
et al Brown lab notes during his research days at Bahnson Labs in North
Carolina 1957-60 period or about. I have a poor chopped up Lab Video
on the subject. I'm looking for the full video the 45 minute one. Mine
is a mere 23 minutes.
I have yet to track down an original document entitled: "The Flying Saucer:
The Application of the Biefeld-Brown Effect to the Solution of Space
Navigation" by Mason Rose. This 50's document details how a flying saucer
operates. I have a copy of a re-write and it is outstanding.
And I'm also looking for a document as seen on SIGHTINGS TV entitled:
"PROJECT SILVER BUG" the 1955 USAF Flying Saucer Tests.
Also, seeking a copy of PROJECT WINTERHAVEN by Thomas Townsend Brown on
a MACH-3 Combat Disc. The British had a stake in as well as the USAF.
It to is from the 1950's.

The Biefeld-Brown (spelling is correct) effect is described generally
as the anomalous tendency of high voltage flat capacitors to display
movement towards (usually) the positive pole. Effects are most often
seen at potentials above 50kv. Thomas Townsend Brown held a few patents
on devices using it. It's very controversial and is part of the subject
of "electrogravitics", as some say that the BB effect is actually polar
gravity peeking out from behind a high electrical gradient within a
dielectric. Claims are that the mass of the dielectric is a factor in
the magnitude of the effect as well as the capacitance and the gradient
intensity. Should be fairly easy for the home-workshop experimenter to
get a look at, but the difficulty seems to be in isolating the effect
from ionic wind and simple electrostatic propulsive effects. Skeptics
claim that those forces are all it ever was, but a few reports indicate
that they may be wrong.

>From Richard Feynman's Lectures on Physics we learn that there is
intrinsic field energy and momentum density associated with a static
electro-magnetic field configuration. When there is a change in the
magnetic field, this field energy and momentum can be directly
converted into kinetic energy and mechanical momentum. Feynman
illustrates this with an electromagnetic carousel paradox. In this
paradox, a dielectric disk (which is embedded with small charged spheres
along its circumference) rotates without any apparent "counter" torque
in the system. Before this rotation occurs, the dielectric disk is
immersed in a static magnetic field. The subsequent rotation occurs as
a consequence to reducing the previously static magnetic field to zero.
The angular momentum and rotational kinetic energy comes directly from
the initial static magnetic field.

A Report on the T. Townsend Brown Conference:
"Focus on Unconventional Energies: A Symposium on Electrical Propulsion &
the Technology of Electro-Gravity"
April 15-16, 1994 Philadelphia Community College, Philadelphia, PA
This conference was held in tribute to Thomas Townsend Brown and I feel that
it was a great success. About 15 speakers and 80 attendees provided a brief
overview of Zero Point Energy theories, Free Energy devices, electrostatics
theory, and antigravity experiments and documentation. Attendees came from
as far away as California and Washington.
The conference program advertised the following topics: "A Review of

Quotation from a letter to William Moore from T. Townsend Brown dated
12/17/76 --
"I am still working on petroelectricity and the project is
housed largely at Stanford Research Institute with additional assistance
being provided by the University of California - Berkeley and the Ames
Research center of NASA. Unfortunately, under the circumstances, while
this project is being evaluated for funding by ERDA we should not and
cannot publish details..."
"Your next question concerns the airfoils. As far as I am
aware, no rf is radiated. There is, of course, a static d.c. field
which accompanies the airfoils in flight."
------------------------------------------------------------------------
It is very interesting to note that Townsend Brown was the pioneer in
this field, and was not able to obtain very much support for his work
until the 1950's. During that time, there was much discussion of
gravity and antigravity within the aerospace industry and in the
magazine "Aviation Week." Then the Gravity Research Group (GRG)
published a detailed summary report of their review of research into
"Electrostatic Motion, Dynamic Counterbary, and Barycentric Control"
(i.e. "Antigravity"). This report is the last public report that
any researchers have been able to find for us that deals with the
physical effects of electrostatics, electrodynamics, and gravity control.
(It is also worth noting that this report was found in the Wright
Patterson Air Force Base Library "TL 565 A9" and was not listed in the
library catalog). So, after the mid-1950's to the present, no other
information regarding the technology of electrodynamics and its effect
on gravity has been able to be found in any of the un-classified U.S.
literature.

I have the FIVE (5) lab books of TT Brown's R&D at the Bahnson Co. in
Salem, N. Carolina 1958-9. I also have some other letters and drawings of
the lab plus the only surviving 16mm colour film of the various stages of
his work at Bahnson Labs.
I was in contact with Dr Brown in 1983 by phone and by mail. He died of
lung cancer not long after in Oct of 1985. He told me that a lot of people
including Bill Morre had attributed more to his work than he had really
done. In particular, he was only marginally connected with the Philadelphia
Experiment as such. His main theme of R&D was dielectrics and the
Biefeld-Brown effect. He was not an electromagnetics man... only
electrostatics.
>From 1983 to 1991 or so I was in frequent communication with J. Frank King
who was TT Brown's boss at the Bahnson Co. J. Frank was a good man and a
good friend of mine. He, too, died in Dec 1989. Before he died I was given
rights to reproduce and share letters, files, drawings, patent submissions,
films etc from his personal files on TT Brown, George Adamski, Dr Ilka, T
Henry Moray and others.
J Frank warned me a long time ago to take what TT Brown said with a 'grain
of salt' because Townsend had a habit of 'stretching the truth' a bit to
get funding which he was always in need of.... So, I warn you now in good
faith: If you seek lost or hidden technology in Brown's lab notes, I don't
think you will find it there; however, I am prepared to make photocopies
available to you.
There are about 750 pages in all. I would need to charge you AUS$50 per
notebook which would include the air mail charges as well. In US$ that
would be about US$38 per notebook. The film is available as are the
notebooks (I think) from The Electric Spacecraft Journal in the US

As far as I know, the last thing Brown published before his
death was, "On The Possibilities of Optical-Frequency Gravitational
Radiation", 2/14/1976 and 8/30/1976. I don't know where it was
originally published. But you can get copy from:
Rex Research, P.O. Box 19250, Jean NV 89019
It is part of NR 046-BT2/B17-BRV "T. Brown: Petro-Voltaics"
(Gravito-Electric Conversion). Most people think Brown was just
into flying capacitors he was into much much more...

Title: Remarks on Pure Spin Connection Formulations of Gravity
Authors: Riccardo Capovilla and Ted Jacobson
Abstract: In the derivation of a pure spin connection action
functional for gravity two methods have been proposed. The first
starts from a first order lagrangian formulation, the second from a
hamiltonian formulation. In this note we show that they lead to
identical results for the specific cases of pure gravity with or
without a cosmological constant.

QUANTUM EINSTEIN-MAXWELL FIELDS: A UNIFIED VIEWPOINT FROM THE LOOP
REPRESENTATION, R. Gambini, J. Pullin, 13pp. no figures.
We propose a naive unification of Electromagnetism and General
Relativity based on enlarging the gauge group of Ashtekar's new
variables. We construct the connection and loop representations and
analyze the space of states. In the loop representation, the
wavefunctions depend on two loops, each of them carrying information
about both gravitation and electromagnetism. We find that the
Chern-Simons form and the Jones Polynomial play a role in the model.

Massive Spin-5/2 Fields Coupled to Gravity: Tree-Level Unitarity vs. the
Equivalence Principle, Massimo Porrati, 6 pages.
I show that the gravitational scattering amplitudes of a spin-5/2
field with mass $m\ll M_{Pl}$ violate tree-level unitarity at
energies $\sqrt{s}\approx\sqrt{mM_{Pl}}$ if the coupling to gravity
is minimal. Unitarity up to energies $\sqrt{s}\approx M_{Pl}$ is
restored by adding a suitable non-minimal term, which gives rise to
interactions violating the (strong) equivalence principle. These
interactions are only relevant at distances $d\lequiv 1/m$.

MAXWELL FIELDS IN SPACETIMES ADMITTING NON-NULL KILLING VECTORS, by Istvan
Racz, 7 pages,PACS numbers: 04.20.Cv, 04.20.Me, 04.40.+c
We consider source-free electromagnetic fields in spacetimes
possessing a non-null Killing vector field, $\xi^a$. We assume
further that the electromagnetic field tensor, $F_{ab}$, is
invariant under the action of the isometry group induced by $\xi^a$.
It is proved that whenever the two potentials associated with the
electromagnetic field are functionally independent the entire
content of Maxwell's equations is equivalent to the relation
$\n^aT_{ab}=0$. Since this relation is implied by Einstein's
equation we argue that it is enough to solve merely Einstein's
equation for these electrovac spacetimes because the relevant
equations of motion will be satisfied automatically. It is also
shown that for the exceptional case of functionally related
potentials $\n^aT_{ab}=0$ implies along with one of the relevant
equations of motion that the complementary equation concerning the
electromagnetic field is satisfied.

UPR-0540-T, To appear in Physica Scripta.
The gravitational effect of vacuum polarization in space exterior to
a particle in (2+1)-dimensional Einstein theory is investigated. In
the weak field limit this gravitational field corresponds to an
inverse square law of gravitational attraction, even though the
gravitational mass of the quantum vacuum is negative. The paradox is
resolved by considering a particle of finite extension and taking
into account the vacuum polarization in its interior.

THE FRENET SERRET DESCRIPTION OF GYROSCOPIC PRECESSION B.R.Iyer and
C.V.Vishveshwara , 37 pages, Paper in Latex.
The phenomenon of gyroscopic precession is studied within the
framework of Frenet-Serret formalism adapted to quasi-Killing
trajectories. Its relation to the congruence vorticity is
highlighted with particular reference to the irrotational congruence
admitted by the stationary, axisymmetric spacetime. General
precession formulae are obtained for circular orbits with arbitrary
constant angular speeds. By successive reduction, different types of
precessions are derived for the Kerr - Schwarzschild - Minkowski
spacetime family. The phenomenon is studied in the case of other
interesting spacetimes, such as the De Sitter and Godel
universes as well as the general stationary, cylindrical, vacuum
spacetimes.

Renormalized vacuum expectation values of electromagnetic
stress-energy tensor are calculated in the background
spherically-symmetrical metric of the wormhole's topology. Covariant
geodesic point separation method of regularization is used.
Violation of the weak energy condition at the throat of wormhole
takes place for geometry sufficiently close to that of infinitely
long wormhole of constant radius irrespectively of the detailed form
of metric. This is an argument in favour of possibility of existence
of selfconsistent wormhole in empty space maintained by vacuum field
fluctuations in the wormhole's background.

Generating new magnetic universe solutions from old. By David Garfinkle and
M.A. Melvin. 17 pages
In this paper we apply the techniques which have been developed over
the last few decades for generating nontrivially new solutions of
the Einstein-Maxwell equations from seed solutions for simple
spacetimes. The simple seed spacetime which we choose is the
"magnetic universe" to which we apply the Ehlers transformation.
Three interesting non-singular metrics are generated. Two of these
may be described as "rotating magnetic universes" and the third as
an "evolving magnetic universe." Each is causally complete - in that
all timelike and lightlike geodesics do not end in a finite time or
affine parameter. We also give the electromagnetic field in each
case. For the two rotating stationary cases we give the projection
with respect to a stationary observer of the electromagnetic field
into electric and magnetic components.

Energy-Momentum Restrictions on the Creation of Gott Time Machines, by Sean
M. Carroll, Edward Farhi, Alan H. Guth, and Ken D. Olum. Plain TeX, 41 pages
incl. 9 figures. MIT-CTP #2252.
The discovery by Gott of a remarkably simple spacetime with closed
timelike curves (CTC's) provides a tool for investigating how the
creation of time machines is prevented in classical general
relativity. The Gott spacetime contains two infinitely long,
parallel cosmic strings, which can equivalently be viewed as point
masses in (2+1)-dimensional gravity. We examine the possibility of
building such a time machine in an open universe. Specifically, we
consider initial data specified on an edgeless, noncompact,
spacelike hypersurface, for which the total momentum is timelike
(i.e., not the momentum of a Gott spacetime). In contrast to the
case of a closed universe (in which Gott pairs, although not CTC's,
can be produced from the decay of stationary particles), we find
that there is never enough energy for a Gott-like time machine to
evolve from the specified data; it is impossible to accelerate two
particles to sufficiently high velocity. Thus, the no-CTC theorems
of Tipler and Hawking are enforced in an open (2+1)-dimensional
universe by a mechanism different from that which operates in a
closed universe. In proving our result, we develop a simple method
to understand the inequalities that restrict the result of combining
momenta in (2+1)-dimensional gravity.

DO INERTIAL ELECTRIC CHARGES RADIATE WITH RESPECT TO UNIFORMLY ACCELERATED
OBSERVERS?, George E.A. Matsas, 6 pages (REVTEX 3.0), IFT-P017/94.
We revisit the long standing problem of analyzing an inertial
electric charge from the point of view of uniformly accelerated
observers in the context of semi-classical gravity. We choose a
suitable set of accelerated observers with respect to which there is
no photon emission coming from the inertial charge. We discuss this
result against previous claims [F. Rohrlich, Ann. Phys. (N.Y.) vol:
22, 169 (1963)]. (This Essay was awarded a Honorable Mention for

Spin Dynamics of the LAGEOS Satellite in Support of a Measurement of the
Earth's Gravitomagnetism, Salman Habib, Daniel E. Holz, Arkady Kheyfets,
Richard A. Matzner, Warner A. Miller and Brian W. Tolman, 16 pages, RevTeX,
LA-UR-94-1289. (Part I of II, postscript figures in Part II).
LAGEOS is an accurately-tracked, dense spherical satellite covered
with 426 retroreflectors. The tracking accuracy is such as to yield
a medium term (years to decades) inertial reference frame determined
via relatively inexpensive observations. This frame is used as an
adjunct to the more difficult and data intensive VLBI absolute frame
measurements. There is a substantial secular precession of the
satellite's line of nodes consistent with the classical, Newtonian
precession due to the non-sphericity of the earth. Ciufolini has
suggested the launch of an identical satellite (LAGEOS-3) into an
orbit supplementary to that of LAGEOS-1: LAGEOS-3 would then
experience an equal and opposite classical precession to that of
LAGEOS-1. Besides providing a more accurate real-time measurement of
the earth's length of day and polar wobble, this paired-satellite
experiment would provide the first direct measurement of the general
relativistic frame-dragging effect. Of the five dominant error
sources in this experiment, the largest one involves surface forces
on the satellite, and their consequent impact on the orbital nodal
precession. The surface forces are a function of the spin dynamics
of the satellite. Consequently, we undertake here a theoretical
effort to model the spin ndynamics of LAGEOS. In this paper we
present our preliminary results.

Generation of Electro and Magneto Static Solutions of the Scalar-Tensor
Theories of Gravity, William Bruckman, 28 pages, LaTeX.
The field equations of the scalar-tensor theories of gravitation are
presented in different representations, related to each other by
conformal transformations of the metric. One of the representations
resembles the Jordan-Brans-Dicke theory, and is the starting point
for the generation of exact electrostatic and magnetostatic exterior
solutions. The corresponding solutions for each specific theory can
be obtained by transforming back to the original canonical
representation, and the conversions are given for the theories of
Jordan-Brans-Dicke, Barker, Schwinger, and conformally invariant
coupling. The electrostatic solutions represent the exterior metrics
and fields of configurations where the gravitational and electric
equipotential surfaces have the same symmetry. A particular family
of electrostatic solutions is developed, which includes as special
case the spherically symmetric solutions of the scalar-tensor
theories. As expected, they reduce to the well-known
Reissner-Nordstrom metric when the scalar field is set equal to
a constant. The analysis of the Jordan-Brans-Dicke metric yields an
upper bound for the mass-radius ratio of static stars, for a class
of interior structures.

Modification of the Coulomb potential from a Kaluza-Klein model with a
Gauss-Bonnet term in the action, by H. H. Soleng and O. Gron, 27 pages,
compressed and uuencoded postscript file with unpacking instructions; major
revision to section IV.D.2 on pages 15-16 ("Corrections to the Coulomb
potential at short distances") and to the figure on page 27,
to be published in The Annals of Physics (NY), NORDITA 94/50
In four dimensions a Gauss-Bonnet term in the action corresponds
to a total derivative, and it does not contribute to the classical
equations of motion. For higher-dimensional geometries this term has
the interesting property (shared with other dimensionally continued
Euler densities) that when the action is varied with respect to the
metric, it gives rise to a symmetric, covariantly conserved tensor
of rank two which is a function of the metric and its first and
second order derivatives. Here we review the unification of General
Relativity and electromagnetism in the classical five-dimensional,
restricted (with g55 = 1) Kaluza-Klein model. Then we discuss the
modifications of the Einstein-Maxwell theory that results from
adding the Gauss-Bonnet term in the action. The resulting
four-dimensional theory describes a non-linear U(1) gauge theory
non-minimally coupled to gravity. For a point charge at rest, we
find a perturbative solution for large distances which gives a
mass-dependent correction to the Coulomb potential. Near the source
we find a power-law solution which seems to cure the short-distance
divergency of the Coulomb potential. Possible ways to obtain an
experimental upper limit to the coupling of the hypothetical
Gauss-Bonnet term are also considered.

KALUZA-KLEIN THEORY IN PERSPECTIVE, M. J. Duff, 38 pages latex, NI-94-015
The Kaluza-Klein idea of extra spacetime dimensions continues to

ways somewhat different from that originally envisaged. We present a
modern perspective on the role of internal dimensions in physics,
focussing in particular on superstring theory. A novel result is the

Recently it has been shown that, if sources are appended in a certain
way to the field equations of Einstein's unified theory, the contracted
Bianchi identities and the field operations appear endowed with definite
physical meaning. The theory looks like a gravoelectrodynamics in a
polarizable Riemmannian continuum. The wealth of the implied possibilities
is far richer than in the so-called Einstein-Maxwell theory.

We investigate all the four-body graviton interaction processes:
gX -> gamma X, gX -> gX, and gg -> gg,
with X as an elementary particle of spin less than two in the
context of linearized gravity except the spin-3/2 case. We show
explicitly that gravitational gauge invariance and Lorentz
invariance cause every four-body graviton scattering amplitude to be
factorized. We explore the implications of this factorization
property by investigating polarization effects through the covariant
density matrix formalism in each four-body graviton scattering
process.

I have recently come into possession of a paper on magneto-gravitics
and field resonance systems, presented by A.C. Holt from NASA Johnson
Space Center to the American Institute of Aeronautics and Astronautics'
16th Joint Propulsion Conference, June 30-July 2, 1980.
Holt presents a project using an already existing system known as the
Coherent Field and Energy Resonance System (CoFERS) [probably located
at Los Alamos Labs' High Magnetic Field Research Laboratory].
CoFERS utilizes a toroidal-shaped energy guide with megagauss magnetic
field sources located along radius vectors equally spaced around the toroid.
CoFERS is shaped like a thick flying disc.
Holt goes on to say: "By converying an object's normal space-time
energy pattern to an energy pattern which differs substantially from the
normal pattern, the gravitational forces acting on the object are changed.
The object's new pattern interacts with the surrounding space-time and
virtual energy patterns, such that the interactive forces are substantially
altered. The alteration of the characteristics of the continuous field of
force results in the apparent motion of the object *through space-time*."
[...] "Since the gravitational forces acting on the propulsion system can be
quickly altered to achieve the desired motion, the *spacecraft* can make
right-angle turns at very-high velocities without adversely affecting the
crew or system elements. The effective gravitational field the *spacecraft/
aircraft* experiences can be nearly simultaneously reoriented at a 90-
degree angle, resulting in a smooth continuous motion as far as the
occupants are concerned." [ ... ] "The gravimagnetic system is perhaps
best suited for use in and around ... a large mass such as the Earth."
"While the gravimagnetic system is likely to be the first field-dependent
propulsion system developed, the field resonance system will **bring stellar
and galactic travel out of the realm of science fiction**. The field
resonance system artificially generates an energy pattern which precisely
matches or resonates with a virtual pattern associated with a distent
space-time point. According to the model, if a fundamental or precise
resonance is established, (using hydromagnetic wave fine-tuning techniques),
the spacecraft will be very strongly and equally repelled by surrounding
virtual patterns. At the same time, through the virtual many-dimensional
structure of space-time, a very strong attraction with the virtual pattern
of a distant space-time point will exist. ...this combination of very
strong forces will result in the translocation of the spacecraft from its
initial position through the many-dimensional virtual structure to the
distant space-time point. [ ... ] "A space-time 'jump' already appears to
be supported by astrophysical research."

The interaction of a gravitational wave with a system made of an RLC

investigated. We show that, in some configurations, the coherent
interaction of the wave with both the mechanical oscillator and the
RLC circuit gives rise to a mechanical quality factor increase of
the electromagnetic signal. When this system is used as an amplifier
of gravitational periodic signals a sensitivity of $10^{-30}$ on the

Spin-orbit and spin-spin effects in the gravitational interaction
are treated in a close analogy with the fine and hyperfine
interactions in atoms. The proper definition of the cener-of-mass
coordinate is discussed. The technique developed is applied then to
the gravitational radiation of compact binary stars. Our result for
the spin-orbit correction differs from that obtained by other
authors. New effects possible for the motion of a spinning particle
in a gravitational field are pointed out. The corresponding
corrections, nonlinear in spin, are in principle of the same order
of magnitude as the ordinary spin-spin interaction.

The Hamiltonian formulation of the motion of a spinning relativistic

approach is based on the introduction of new coordinates and their
conjugated momenta to describe the spin degrees of freedom together
with an appropriate set of constraints in the Dirac formulation. For
particles with gyromagnetic ratio $g=2$, the equations of motion do
not predict any deviation from the standard Lorentz force, while for
$g \neq 2$ an additional force, which corresponds to the magnetic
dipole force, is obtained.

Structure, Erice, August 1995.
The recent series of experiments on polarized lepton-nucleon
scattering have provided a strange new twist in the story of the
nucleon, some of whose aspects are reviewed in these lectures. In
the first lecture, we review some issues arising in the analysis of
the data on polarized structure functions, focusing in particular on
the importance and treatment of high-order QCD perturbation theory.
In the second lecture some possible interpretations of the ``EMC
spin effect" are reviewed, principally in the chiral soliton
(Skyrmion) approach, but also interpretations related to the axial
$U(1)$ anomaly. This lecture also discusses other indications from
recent LEAR data for an $\bar{s} s$ component in the nucleon wave
function, and discusses test of a model for this component. Finally,
the third lecture reviews the implications of polarized structure
functions measurements for experiments to search for cold dark
matter particles, such as the lightest supersymmetric particle and
the axion, after reviewing briefly the astrophysical and
cosmological evidence for cold dark matter.

"Mechanical Propulsion From Unsymmetrical Magnetic Induction Fields"
by: R.L. Schlicher A.W. Biggs W.J. Tedeschi
31st AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit,
July 10-12 1995
A method is presented for generating mechanical spacecraft propulsion
from unsymmetrical magnetic induction fields. It is based on an
unsymmetrical three-dimensional loop antenna structure driven by a
repetitively-pulsed high-current power supply. Antenna geometry is
optimized for generating propulsive thrust rather than radiating
electromagnetic energy. A magnetic field density gradient imbalances
the magneto-mechanical forces that result from the interations of
the internal magnetic induction field with the current in the conductors
of the antenna structure.
From Richard Feynman's Lectures on Physics we learn that there is
intrinsic field energy and momentum density associated with a static
electro-magnetic field configuration. When there is a change in the
magnetic field, this field energy and momentum can be directly
converted into kinetic energy and mechanical momentum. Feynman
illustrates this with an electromagnetic carousel paradox. In this
paradox, a dielectric disk (which is embedded with small charged spheres
along its circumference) rotates without any apparent "counter" torque
in the system. Before this rotation occurs, the dielectric disk is
immersed in a static magnetic field. The subsequent rotation occurs as
a consequence to reducing the previously static magnetic field to zero.
The angular momentum and rotational kinetic energy comes directly from
the initial static magnetic field.
