... ng to receiving circuit, and the power gradient therefore is characteristic of the direc- tion of the flow of energy.) In the space outside of the conductor, during the flow of energy through the circuit, a condition of stress exists which is called the electric field of the conductor. That is, the surrounding space is not uniform, but has different electric and magnetic properties in different directions.

The law of gravitation has been recast, and the force of gravitation has become an effect of inertial motion, like centrifugal force. The ether has been abandoned, and the field of force of Faraday and Maxwell has become the fundamental conception of physics.

... eding lecture, the conception of the ether as the carrier of radiation had to be abandoned as incompatible with the theory of relativity; the conception of action at a distance is repugnant to our reasoning, and its place is taken by the conception of the field of force, or, more correctly, the energy field. The energy field is a storage of energy in space, character- ized by the property of exerting a force on any body susceptible to this energy — that is, a magnetic field on a magnetizable body, a gravitational field ...Chapter 15: Distributed Capacity, Inductance, Resistance, And Leakage - 4 hit(s)
