In their approach to Earth dynamics the authors
consider the fundamentals of Jacobi Dynamics
(1987, Reidel) for two reasons. First, because satellite
observations have proved that the Earth does not stay in
hydrostatic equilibrium, which is the physical basis of
today’s treatment of geodynamics. And secondly, because
satellite data have revealed a relationship between
gravitational moments and the potential of the Earth’s
outer force field (potential energy), which is the basis
of Jacobi Dynamics. This has also enabled the
authors to come back to the derivation of the classical
virial theorem and, after introducing the volumetric
forces and moments, to obtain a generalized virial
theorem in the form of Jacobi’s equation. Thus a
physical explanation and rigorous solution was found for
the famous Jacobi’s equation, where the measure of the
matter interaction is the energy. The main dynamical
effects which become understandable by that solution can
be summarized as follows: • the kinetic
energy of oscillation of the interacting particles which
explains the physical meaning and nature of the
gravitation forces; • separation of the
shell’s rotation of a self-gravitating body with respect
to the mass density; difference in angular
velocities of the shell rotation; •
continuity in changing the potential of the outer
gravitational force field together with changes in
density distribution of the interacting masses
(volumetric center of masses); • the nature
of the precession of the Earth, the Moon and satellites;
the nature of the rotating body’s magnetic field and the
generation of the planet’s electromagnetic field. As
a final result, the creation of the bodies in the Solar
System having different orbits was discussed. This
result is based on the discovery that all the averaged
orbital velocities of the bodies in the Solar System and
the Sun itself are equal to the first cosmic velocities
of their proto-parents during the evolution of their
redistributed mass
density. Audience The work is a
logical continuation of the book Jacobi Dynamics
and is intended for researchers, teachers and students
engaged in theoretical and experimental research in
various branches of astronomy (astrophysics, celestial
mechanics and stellar dynamics and radiophysics),
geophysics (physics and dynamics of the Earth’s body,
atmosphere and oceans), planetology and cosmogony, and
for students of celestial, statistical, quantum and
relativistic mechanics and hydrodynamics.
