Causality, Electromagnetic Induction, and Gravitation: A Different Approach to the Theory of Electromagnetic and Gravitational Fields
If you are unused to computing with delayed (retarded) potentials, as I am, then the "warm up" book would be "Electromagnetic Retardation and the Theory of Relativity." That would be the place to start exploring Jefimenko's point of view if you have already had a good course in electromagnetic theory. Otherwise, the author's book "Electricity and Magnetism" would be the right start. This volume begins with a chapter on causality, making the point that both the electric and the magnetic field arise causally from a common ancestor, but that they do not mutually cause each other. Given his formalism, the point is fair, and I think there is no use in contesting the point. However, the two do arise together from a common source and they do act as people have always supposed they act. So, this point seems to be a matter of intellectual precision and not really too practical---for now. I think that many main-stream physicists might object that Jefimenko is splitting hairs, but to me it seems to be wrong. We begin usually with Maxwell's equations in a differential form. With blundering calculations, we find them to be Lorentz invariant. So what? Well, we end up being forced to notice that time measurements at different locations have to be synchronized more carefully than we had imagined. We get effects usually called "special relativistic." But there is a problem in that we began saying time means one thing and we end up finding it means something a little different. So, Jefimenko's extra care is needed, and not wasted. I think his way is very important and gets too little attention.
The author resurrects some 1893 work by Heaviside to postulate that gravitational fields have more in common with electromagnetic law than the repulsion of static gravitation, and that both sciences can benefit from a time-dependent treatment that illustrates causality better than Maxwell's equations. Conclusions include a force of cogravitation analogous to the magnetic force, non-instantaneous propagation of gravitation, and the existence of five (5) gravitational forces. Rejecting the idea that E and H cause each other, Jefimenko shows that mass, change in mass density, and mass currents are the origin of both the gravitation and cogravitation vectors. Highly recommended for those who want to learn fields and waves by thinking. about them Urgently relevant because of the recent detection of gravity waves -- this book will give you a background even if you disagree with it.
Do you think NASA knows everything when it comes to new technology?
Well, think again…
A brilliant engineer from Lexington, Kentucky revealed a secret project that will change the electricity history forever.
✔ The Real Nature of Tesla AC Generator
✔ Combination of induction motor and alternator
✔ Combination between generators
✔ Or maybe called Overunity for the system. Mother Nature doesn't care about people calling or naming phenomena. Overunity or Free Energy, or Zero Point Energy (ZPE) are just a few different words
Rumors say it’s the most efficient new source of energy.
NASA engineers don’t see how they missed it and are trying to figure out the technology behind it.
I think you deserve to find everything out.
