    Charles Berlitz.  Chapter 10 "The Force Fields of Townsend Brown".
    These two items are the same, I just don't know which one came first.
            Also there is more than one book with the title "The
    Philadelphia Experiment".  You want the one with ISBN 0-449-20526-6.

       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.

    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 $d\lequiv 1/m$.

         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.

         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 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

         Violation of the weak energy condition at the throat of wormhole
         takes place for geometry sufficiently close to that of infinitely

         We present a unified description of gravity and electromagnetism in
         the framework of a Z2 noncommutative differential calculus. It
         can be considered as a ``discrete version" of Kaluza-Klein theory,
         where the fifth continuous dimension is replaced by two discrete
         points. We derive an action which coincides with the dimensionally
         reduced one of the ordinary Kaluza-Klein theory.

    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.

    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.

         The solution of Einstein vacuum equation, for a static

     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.
