This chapter considers the gravitational field of the earth. The chapter mentions the forces acting on elementary volume of the rotating Earth in an inertial frame and considers the second Newton's law in non-inertial system. It introduces the centrifugal force and gravitational field, as well as...
The ratio of nuclear spin-precession frequencies of Hg-199 and Hg-201 atoms were measured for two orientations of magnetic field relative to the earth's gravitational field. It is found that the spin-dependent component of gravitational energy is less than 2.2 x 10 exp -21 eV, a substantial...

We observe and personally feel that natural climate change, seasonal alternation, and the growth and apoptosis of all things are always circulating in the vortex gravitational field of the earth and sun. From the cosmic accretion disk to quantum spin, the vortex gravitational field is ubiquitous. ...
Boeing’s CST-100 Starliner is still docked to the International Space Station, more than two months into a stay originally planned to be as short as eight days. Jeff Foust reports on the ongoing discussions at NASA about whether the spacecraft can safely return to Earth with astronauts on ...
But electromagnetism and gravity aren’t quite equal here. Gravity is important, obviously, but it’s also pretty simple: everything attracts everything else. (We’re ignoring cosmology etc, focusing in on life here on Earth.) That’s nice — it’s good that we stay attached to the groun...
While this indicates that chromite mineralization occurs within the narrow ultramafic series between the intrusions, implying that semi-continuous chromitite extends across the DEI (akin to BTI chromitites), it does not provide sufficient evidence to suggest that these mineralized zones are fragments of...
Nevertheless, the gravimetric interpretation of the Earth’s mantle density structure (controlled mainly by mantle convection flow) might be improved by applying forward modelling and the subsequent removing of the gravitational signature of lithospheric density and geometry variations in the geoidal ...
