Organization is in 20 chapters beginning with a brief survey of analytical dynamics and ending with chapters on quantum theory of free electromagnetic field, interaction of radiation with matter, and Bell's inequality.
In order for Maxwell's equations to satisfy Einstein's equations, it is shown that: (1) a free electromagnetic field along the trajectory of an orbiting body must be present, by means of purely magnetic "standing" waves; (2) electromagnetic fields don't satisfy the Einstein equations in a region of orbiting space bodies if there is no distribution of another substance (e.
A free electromagnetic field along the trajectory of an orbiting body ([omega] [not equal to] 0, v [not equal to] 0) cannot be zero, and is represented by purely magnetic "standing" waves (all components of the electric strength are [E.
