Crap. And argh. I thought it was more useful than that. Who knew? Stalin had the science writers purge their texts of those qualities that you miss and that we enjoy here in the west (they were condemned as bourgeois inspired perversions with counter-revolution tendencies). Hence you find decrepit pensioners sneering at elitist propaganda (western science) that dismisses the party-approved water models of RF transmission. In the historical perspective, we have to remember this state inspired instruction was learned in an era of RF transmission jammers located in every neighborhood so that trying to hear the VOA or the BBC made things sound like you were listening through the breakers of the surf. Hence the "experience" of the water model was very pervasive and arguing its falsity comes up against the resistance of the old guard. Always are the two descriptions. Physical (dynamic) and geometric (kinetic). "Geometric algebra in the sense used in this article was not developed, however, until 1844, when it was used in a systematic way to describe the geometrical properties and transformations of a space "Nevertheless, another revolutionary development of the 19th-century would completely overshadow the geometric algebras: that of vector analysis, developed independently by Josiah Willard Gibbs and Oliver Heaviside. Vector analysis was motivated by James Clerk Maxwell's studies of electromagnetism, " From: http://en.wikipedia.org/wiki/Geometric_algebra Tesla's longitudinal radio waves are also described. For us is enough to know that the transversal are rotational. The geometric desription of the rotational oscillations is very impressive. It must be in the school program. Stokes drift is also impressive. Do you know that the ink printer use it? S* |

How does one detect the imaginary plane? Movements in 2D are described on the imaginary plane, in 3D by vector calculus, in more D by tensors. You need not know that to analise the radio waves. But you should know that no pure transversal waves. Always are the two components. Heaviside did not know that. S* |

As you know I am collecting the evidences. Could you tell me something about the cristal radio? There is the diode. The electrons flow in the one direction. The questions a 1. Electron must flow from the antenna to the ground, 2. In the opposite direction. 3. Radio works in the both arrangement. The faded political trash that is now used as decoupage for today's arguments is carnival in spirit but is as nutritionally substantial as cotton candy. It would be easy to collect the information from the own laboratory. But asking is the substantial. S* |

1. Electron must flow from the antenna to the ground, Nope, RF electrons don't actually flow. They essentially vibrate in place. "For a copper wire of radius 1 mm carrying a steady current of 10 amps, the DC drift velocity is only about 0.24 nanometer per microsecond." At 10 MHz, the electrons would vibrate back and forth at about 0.01 nanometer per 0.1 microsecond. Consider how large 0.01 nanometer really is so for all practical purposes, electrons don't flow at all at HF frequencies. Electrons at HF are just a bucket brigade for the photons that deliver the RF energy to the diode detector. Unless a circuit is at DC steady-state, photons are involved, i.e. RF involves photons which constitute the RF fields and RF waves. -- 73, Cecil, w5dxp.com |

There are only two resistances in radiation and if no skin depth is then generated then the material and its resistance is removed from Maxwell's equations Now one can question my understanding as to what is happening but the fact is my antenna swr does not go above 3:1 no matter what band I am on! Yes, by not understanding what is really happening it would be easy to say "dummy load " but that is not the real answer. So I would ask all what exactly is impossible about the sequence of event that I describe while adding that computer programs confirm it?

I know what the answer will be of course, an excuse why you can't have a Q with me or anyone else. tom K0TAR |
