This only works for a rational discussion. S* is only interested in pursuing agitprop, the failure of a decandent counter-cultural ideology. You wrote: "Yes, indeed it does matter who is "writing history." *The quotation above is, in fact, quite wrong." So the best approach is to take a glance into the original papers. In Maxwell's model the magnetic lines are like the smoke rings. Nothing flow along them. In Heaviside's model there is the solenoidal flow. It is not simplification. The both models are quite different. But the both are a history. Your radio waves travel in rare plasma. It is interesting that Faraday predicted it. S* they may travel through a rare plasma, but the rare plasma is not needed for their propagation. they also travel through dense matter like glass, but the glass is not needed for their propagation. |

"The velocity of light through space is about 190,000 miles in a second; the velocity of electricity is, by the experiments of Wheatstone, shown to be as great as this," For this reason Faraday concluded: " "I suppose we may compare together the matter of the aether and ordinary matter (as, for instance, the copper of the wire through which the electricity is conducted), and consider them as alike in their essential constitution; i.e. either as both composed of little nuclei, considered in the abstract as matter" Everywhere are "nuclei" (electrons). You simply do not read Faraday. He also described a dipole: " For suppose two bodies, A B, distant from each other and under mutual action, and therefore connected by lines of force, and let us fix our attention upon one resultant of force, having an invariable direction as regards space; if one of the bodies move in the least degree right or left, or if its power be shifted for a moment within the mass (neither of these cases being difficult to realise if A and B be either electric or magnetic bodies), then an effect equivalent to a lateral disturbance will take place in the resultant upon which we are fixing our attention; for, either it will increase in force whilst the neighboring results are diminishing, or it will fall in force as they are increasing." " if its power be shifted for a moment within the mass" = if electrons oscillate in a dipole. Wimpie mentioned a monopole. Dipole = two monopole. What does monopole radiate? In your antennas and in the space are free electrons. We do not need a mystery TEM.. S* |

EM waves do not need aether or your free electrons. |

Faraday's classic "The Chemical History of a Candle" may be expressed in archaic language (not really that archaic once you get into the vernacular), but it is an example of extremely clear analysis and instruction. There is absolutely nothing wrong anywhere in that recital. Faraday examined the properties of induction - action at a distance - in equally archaic terms, but with scientifically rigorous methods. The archaic language was confined to terms of invention. Phlogiston, as both a term and concept, was an invented word that was current during his life. I am sure he used the Phlogiston in correspondence with those who understood its context. However, the nature of that correspondence reveals that neither party "believed" in it as a force of nature, and merely used the term and concept as a touchstone insofar as it was a focus of debate. In other words, for them the debate was over and Phlogiston was an intellectual dead-end, but the focus of the underlying question it was supposed to have answered was a question still being discussed. 73's Richard Clark, KB7QHC |

If North, positive half cycles go West and negative half cycles go East. If it is tipped to an undefined angle, the positive and negative half cycles get confused and the electrons refuse to jump off. This makes it good only for receiving. |

What your dipole prodce: TEM waves or "an effect equivalent to a lateral disturbance " ? S* |

S* you must remember, that just because any of those old guys wrote something it doesn't mean that they believed it even a year later. they were all putting up theories and trying to connect electricity and magnetism with just about anything else for many years. it was even many years before anyone figured out that electricity and magnetism were related. you would learn much more by using a modern text that has filtered out all the theories that were thrown away than reading the raw conjectures of early theorists. |
