The book starts with a revision of the fundamentals of the
theory of dynamics and gravitation. The primary object is to
present a relativistic theory of gravitation which is an
extension of the Special Theory of Relativity. The new approach
to gravitomagnetics reproduces results which are identical for
the precession of the perihelion of Mercury and for the
deflection of light grazing the Sun to those given by the
general theory of relativity. Both of these were hailed as
justifications of the general theory. When the new theory is
applied to the precession of a gyroscope in space there is a
small difference from the value quoted to that given for the
NASA/Stanford Gravity Probe B experiment which has just been
completed. The results are due in Spring 2007. In order to
explain the new approach it is necessary to re-examine Newtonian
dynamics and special relativity. Certain aspects are better seen
if force is treated as a defined quantity rather than a primary
one. This idea is not new, it was the view of d'Al
