The Deflection of Light in the Dynamic Theory of Gravity
... In the dynamic theory of gravity an analytical expression for the deflection of light has been derived and evaluated numerically. First as the main body a star having the mass and the radius of the sun was used in calculating the light deflection and next two neutron stars of different masses and ra ...

... A global positioning system (GPS) functions by determining the travel times for EM waves from various satellites to a land-based GPS receiver. If the receiver is to detect a change in travel distance on the order of 3 m, what is the associated change in travel time (in ns) that must be measured? ...

21.3 Finding Scalar Potentials
... NB In this example the vector field G is singular at the origin r = 0. This implies we have to exclude the origin and it is not possible to obtain the scalar potential at r by integration along a path from the origin. Instead we integrate from infinity, which in turn means that the gravitational pot ...
