wrote: I reply (is it OK "reply"?) Hi Miguel, Your usage is fine. to Richard first because it is part of my comment to Cecil. Yes, Richard. Tonight I said to me: -the worst term that you could use, Miguel, was "ether"- :), because "ether" is a hipotetical MATERIAL thing, Hypothetical. so, as on other material mediums we usually can literally see interference because interference is manifested on matter, but we need photographic plates, screens, retinas, etc. to manifest electromagnetic interference, "loads" as say Richard, ("observer" it is more sutil and difficult concept, I dare not with "him"). I needed know what represent that in a line discontinuity (in a load seems obvious) to better understand Cecil's examples in web page (http://www.w5dxp.com/energy.htm). Representing, representation, like the term redistribution, are all crutches for intellect. If you get stuck on one, you are forever behind. If it works - fine. When the crutch breaks, you have to be able to walk away without feeling cheated. (Amusing, being able to walk away means you never needed the crutch in the first place.) .... Before continue I want to do a comment to know if we agree (more or less). We partially think with words or symbols, words and symbols represent concepts or perceptions, concepts are not "out there", as Einstein said they a "free creations of human mind". There is not energy out there, there is not velocity out there, that things are in our brains (or consciusness if you prefer). We need consensus to collective think on it, we need "sincrhonize" our minds to Synchronize. colectivelly think the world... You think in english, I think in spanish, I need translate "your" words to "my" words to understand what you say, I can not say: "whats the hell is a rig!", where are "rigs"! only there are "equipos" boys! :) For that I need understand what means Cecil with redistribution, I belieive I can understand his idea behind the word, I must make the effort because my own language barrier. Perhaps the consensus word to it may be not "redistribution", but... what Cecil tries explain to me? I try never identify the "map" (words, concepts) with the "territory" (hipotetical real world) because misleading me. Redistribute is an action verb. Nothing happens until you measure it (you need a load). This speaks to your Ether (or Aether or Æther) being a medium, but there is no evidence of Ether existing. So for action, it is in the loading - nothing else happens (has action) without a load. The "concept" of redistribution collapses to zero if you do not take a measure, but it exists if you do? Logically, the causal relationship is with the observation, not with the energy. The load reveals a concept that does not exist without it. What you wonder about and call a map, or territory, is a forest of loads that give a population of varied responses that are a product of phase differences. Mathematical "representations" of this are called surface maps (your term of map is appropriate) or contour maps. Within these types of representation, you can see patterns. However, the patterns are those revealed by a multitude of loads. Take away the loads and you would see nothing. (Richard I do not think wathever reflects also absorbs (ideally at last), It can reflects an transmits but nor absorb, do you agree with it?) No. I have measured light at the bench, and I have studied its applications at many scales down to subwavelength dimensions. All materials absorb light without qualification. All materials reflect light without qualification. All materials transmit light without qualification. You may be tempted to tightly constrain what you call light to force an artificial solution. Do not do it, because that serves no useful purpose. Consider the sun, light (a photon) from its center has to penetrate its bulk before we see it. It takes something like 10,000 years for that light to reach the surface. Any material you think of here on our mud ball planet is inconsequential in comparison. Using an optical analogy for RF is very dangerous if you cannot measure it at the bench. Why try to understand two unknowns together? The greatest danger of an optical analogy is in your perception (I choose that word with care) that IF you are able to "see" it, THEN that means that you "understand" it. Sight is an illusion (another word chosen with care) that is most often clouded by the mind. This topic fills books from both academic and popular writers. In simple terms, there are optical events that you are certain you can see, but that you cannot measure or show anyone else. There are optical events you and others can measure, but you cannot see. A simple (but complex one to build) example is the conjugate mirror. It reflects light, but when you look into it, all you see is black. If you have no experience at the bench, then what I write is a puzzle. Although I have described why this happens, I doubt anyone remembers or knows the answer to this contradiction. If you want a hint, it relates ENTIRELY to your trying to tie together RF, reflection, and other transmission/transmitter topics. Look at the ongoing discussion on source resistance, and note the same word conjugate's appearance in that commentary. 73's Richard Clark, KB7QHC |
