Gravity is the entropy gradient

The paper presents a new concept of gravity as an entropy gradient of thought forms within the framework of the Acta Universi hypothesis. The mechanism of gravitational effects arising through the creation of spatial inhomogeneities in information density is investigated.

Mean Vertical Gradient of Gravity

2001
The Stokes-Helmert scheme for precise geoid determination requires that Helmert’s gravity anomalies are first evaluated on the earth surface. Subsequently, these anomalies must be continued downward onto the geoid, where they make the boundary values for solving the geodetic boundary value problem. The anomalies are continued downward using the Poisson

Processing gravity gradient data

Geophysics, 2011
Abstract As the demand for high-resolution gravity gradient data increases and surveys are undertaken over larger areas, new challenges for data processing have emerged. In the case of full-tensor gradiometry, the processor is faced with multiple derivative measurements of the gravity field with useful signal content down to a few ...

The normal vertical gradient of gravity

Geophysics, 1983
Abstract Most gravity surveys are conducted to estimate subsurface density contrasts for one application or another. From large-scale crustal studies to relatively small exploration surveys, it is necessary to determine in some way what the normal gravity field should be in order to identify anomalous features.

Gravity-Gradient Momentum Management

Journal of Spacecraft and Rockets, 1972
RBITING space vehicles which use momentum exchange control elements such as control moment gyros (CMGs) and reaction wheels are faced with the problem of possible saturation of such devices. The use of gravity-gradi ent torques for desaturation control would allow the dissipation of accumulated momentum without expending vehicle propellants. This study

The anomalous vertical gradient of gravity

Geophysics, 1970
Abstract The behavior of the earth's vertical gradient of gravity as observed, for example, in tall buildings or boreholes is a matter of considerable geophysical importance. The following elementary considerations may be of interest.
