چکیده
The great blues singer Etta James’ signature song begins, “At laaasst, my love has come along . . . .” This may have been the feeling on May 4th when NASA announced the long-awaited results of Gravity Probe B [1], which are appearing now in Physical Review Letters[2]. Over 47 years and 750 million dollars in the making, Gravity Probe B was an orbiting physics experiment, designed to test two fundamental predictions of Einstein’s general relativity.

On the formation and propagation of nonlinear internal boluses across a shelf break
High-resolution twoand three-dimensional numerical simulations are performed of first-mode internal gravity waves interacting with a shelf break in a linearly stratified fluid. The interaction of nonlinear incident waves with the shelf break results in the formation of upslope-surging vortex cores of dense fluid (referred to here as internal boluses) that propagate onto the shelf. This paper pr...
متن کاملM ay 2 00 4 Modified Gravitational Theory and the Gravity Probe - B Gyroscope Experiment
A possible deviation from the precession of the Gravity Probe-B gyroscope predicted by general relativity is obtained in the nonsymmetric gravity theory. The time delay of radio signals emitted by spacecraft at planetary distances from the Sun, in nonsymmetric gravity theory is the same as in general relativity. A correction to the precession of the gyroscope would provide an experimental signa...
متن کاملAn alternate Hamiltonian formulation of fourth–order theories and its application to cosmology
An alternate Hamiltonian H different from Ostrogradski’s one is found for the Lagrangian L = L(q, q̇, q̈), where ∂2L/∂(q̈)2 6= 0. We add a suitable divergence to L and insert a = q an d b = q̈. Contrary to other approaches no constraint is needed because ä = b is one of the canonical equations. Another canonical equation becomes equivalent to the fourth–order Euler–Lagrange equation of L. Usually, ...
متن کاملThe Variational Approach to Alternative Theories of Gravity
This paper is based on lectures given in Ladek-Zdroj, Poland during the 42nd edition of the Karpac winter school on Theoretical Physics. The aim of these lectures was to give an introduction to a rigorous, mathematically well based, variational approach to alternative theories of Gravity, in view of their very interesting recent applications in the framework of Cosmology. We discuss alternative...
متن کاملTesting Lorentz Symmetry with Gravity
In this talk, results from the gravitational sector of the Standard-Model Extension (SME) are discussed. The weak-field phenomenology of the resulting modified gravitational field equations is explored. The application of the results to a variety of modern gravity experiments, including lunar laser ranging, Gravity Probe B, binary pulsars, and Earth-laboratory tests, shows promising sensitivity...
