Is it wrong? Miguel LU6ETJ Photons are very useful in the analysis of transmission lines. They can be brought into the discussion to divert it from taking a path that makes a participant uncomfortable. If unable to answer a question logically, simply toss photons, optics, quantum mechanics, aether, and other confounding factors in, and presto, people will begin arguing about the spurious concepts and forget that you've avoided answering the difficult question. It's called misdirection, a time-honored technique used by politicians and prestidigitators as well as promoters of pseudoscience. Roy Lewallen, W7EL That reminds me that somewhere in the morass of this thread, I believe I saw an "exchange" about whether it was more proper to think of a TEM line in terms of inductance and capacitance, or in terms of (electric and magnetic) fields. I suppose someone had lost sight of the fact that capacitance is simply a model that relates energy stored in an electric field to the applied voltage, and inductance is simply a model that relates energy stored in a magnetic field to the conducted current. How easy it seems for some to become so invested in a particular viewpoint that they can't see that other viewpoints are equally valid (and often just a different way to say the same thing) -- and may on occasion lead to new insights. Of course, those viewpoints that have little to recommend them don't have to be given a particularly prominent position in our thoughts. Far be it from me to say that 10MHz energy isn't quantized, but since the quanta are far too small for me to measure, I seldom give them much thought. Cheers, Tom |

But you are NOT adding up the energy flows - you are adding up the power. Ummm. Energy flow is power. Joules/s! If it helps, any place I have written 'power', please replace with 'energy flow'. One too many words - what I meant to say is that you are not adding up the energy - you are adding up the power. There is no such thing as conservation of energy flow. That is proved by your own graphs. There are times when the energy flow is destroyed. There are other points on your power graphs where energy flow is created. There is no conflict with conserving flows, ... The conflict is that conservation of flows doesn't exist. Keith, you need to go back to college. There is no such thing as conservation of energy flow so your argument falls apart. When one looks up "conservation" in a physics book one finds: conservation of energy principle conservation of mass-energy conservation of mechanical energy conservation of momentum principle There is NO conservation of energy flow or conservation of power. Until you give up on that ridiculous concept, we don't have much to discuss except your religion. What happens when energy = 1 joule, and de/dt = 0 watts. This happens all the time during an RF cycle so you are not using actual energy flows. You are using power which goes to zero even when maximum energy is still present. Yes, indeed. That is a fundamental possibility and occurs on transmission lines with infinite VSWR. If power goes to zero, power has been destroyed. Therefore, there is no conservation of power principle. Anything that can go to zero, i.e. can disappear, cannot be conserved. Power is the time derivitive of energy. They are related but definitely not one-to-one. Well, that shoots your argument down. If power and energy do not have a one-to-one correspondence, then you cannot use the conservation of energy principle to prove that power is conserved and your argument falls apart. You must then product a conservation of power principle, something that every physics professor has warned us doesn't exist. I can provide any number of references to support the conservation of energy principle. Please provide just one bona fide reference that supports your conservation of energy flow (power) principle. This is quite incorrect. Energy flows must balance, otherwise energy is being created or destroyed to sustain a difference in flow. Good grief! Any physicist knows that is false. Any number of examples prove that is false. Energy flows must balance as well. Otherwise, energy is coming from nowhere to sustain the flow. Given a black box with an input and output. Measurements of the power flow vector indicates that the magnitude of each power flow vector is 50 watts and both vectors are pointing inside the black box. How can the instantaneous energy flows possibly balance? Instead, think that at every instant, the energy flow between the entities in the experiment must balance. You are contradicting yourself. Assume the capacitor *IS* the system inside a black box. The instantaneous energy flow does NOT balance. It is the total energy within the system that is conserved, just as it is the total of the flows of energy between the entities within the system that must be conserved. You have it half right. Energy must be conserved. Energy flow is not conserved. Put more strictly: The sum of all the energy flows in to all of the entities within the system must equal the energy flow in to the system. Please see the black box experiment above and balance the energy flow. Please produce a reference for the conservation of power principle. -- 73, Cecil, w5dxp.com |

Yes, green (actually green-yellow) light corresponds to photopic (day) vision. Scotopic (moonless night) vision is blue-shifted. Sitting inside would tend towards a combination called mesopic vision. The analogue of the eye as "receiver" gives us the peculiar action of resonance shifting due to strength of the QSO. Propagation fading would find the contact drifting from the 80M Band up through the 60M band. Look, light has a very rough "texture", Is Cheeta trying to say photons? light quanta is a very energetic thing, its "granularity" it is high and we easily perceive its quantic nature, The eye can sense one photon out of two under the best of conditions, but what that means as far as "granularity" is lost on me. A RADAR (even if not an 80M one) can respond to a pulse it sends and senses in an echo. The packet contains at least 100 to 10000 cycles. Pulse shape signatures would suggest that individual cycles are resolved - granularity? 80 m energy instead has a very, very "soft" texture, 10^8 time softer than green light, and we can not measure its "granularity" with our instruments. The granularity can be expressed in microKelvins of temperature which can be (and has been) resolved. What you describe as "we can not measure" is more a function of background noise, not ability, nor instrumentation incapacity. Think of a 1000 kg car smashing against your car at 100 km/h, now think of a mosquito (10 mg) smashing against your windshield at the same speed.. well if the one green light quantum had the cinetc energy of a 1000 kg thrown against your car, 80 m quantum would have the mosquito energy! It is a really good example... you should congratulate me for that formidable approach!! no?, hi hi Analogies, as we have mulled them over in the past, often lead to their own failure and that, in turn, brings down the central point trying to be argued. Case in point with your mosquito: The two collision events can also be expressed as energy translation into temperature change. This is called phononic energy - or sound. The crash of cars or bugs resolves into a sound. Do we hear, or do we have the capacity to hear either? Both? There are 8 orders of magnitude difference between the two masses at the same velocities. Our hearing dynamic range easily encompasses that. I can hear bugs bump against my living room window at far slower velocity. I would not hear them with the background noise of an operating automobile and the various road, wind, conversational or radio noises raising the noise floor. This points out that measurement failures are often a matter of method, hence the human component of psychological impairment. Science is more fascinating in its stories of overcoming shortfalls of perception. Einstein wasn't known for his math, or his benchwork, he gave us perspective. Physicists said that we can better perceive energy glanularity at lower temperatures and they say we have classic behaviour when hv kT, well... at 1 K, kT it is 6000 times bigger than 80 m hv, a very classic oscilator indeed!, at 293 K ambient temperature I think we can not appreciate quantized nature of RF waves!, (at least with my Bird 43) :) All the matter of background noise. I have a question too, please tell me (I am very curious): why you take every opportunity to bite (sting?) my friend Cecil, ah? ;). Probably because you enjoy reading it, otherwise why are you offering another opportunity? ;-) 73's Richard Clark, KB7QHC |

Yes, it is dated 1992 a little old, doesn't it?. so... can we today measure quantum acne from large scale 3,5 MHz oscillator at room temperature?

I am sorry because I miss some of your subtleties or grammatical tricks and I suspect they have more funny meanings that I can capture :) Hi Miguel, Sorry for the loss in translation. It is what is called "deep metaphors" that go beyond the simpler ones of mosquitoes against the windshield. I believe what we have more here are psychoanalysts not psychiatrists (I read something about it time ago), but do not worry I am a little crazy too! :) You are correct (about analysts...). Here, the game of language is found in the ellipsis (or the parenthetical aside - this one being doubly self-referential). Look, my first idea example was compare difference in marbels size with hydrogen atom size (about 10^8) to point to granularity, but inmediately I realized that dealing with differences in size was not a correct example and turn to Ec example. You said our retinas sometimes can perceive individual light photons, no? Yes, in the best of circumstances half of those that impact the retina. This returns us to background noise and S+N/N. then I pointed to an eigty meters photon had 10^-8 smaller energy than green photon. Hence the eight orders of scale comparison. Yes. I was telling we are talking about truly classics system therefore quantum effects (photon) it is useless because in our level of discussion oscillators/transmitters do not manifest quantum effects because its very high quantum numbers Of course I know (do I know?, really?, mmm) correspondence principle. You can experience one photon, however could you state that it was not two instead? I have designed with components that are specifically photon counters. These are called photomultiplier tubes (PMTs for short). Where they do not match up against the eye for dynamic range, spectral bandwidth, or quantum efficiency; they do present us with individual events within a group. Our eyes do not count very well. Why at room temperature? Do we see if I understood your question... at room temperature because we Hams usually make our TL Bird Truline measurements at room temperatures. Answer this your question? (my freezer do not go beyond -20 Celcius degrees!). So, I am to understand that you want to measure quantum effects at energy background levels in excess of 0.04 eV or roughly 10 TeraHertz. I don't think you can afford the Bird plug for that band. I come from a field called Metrology. This is so rare that many, many engineers have never heard of it. It is the science of measurement. If you want a quantum correlative to frequency, this field abounds in them. The Atomic Clock (Cesium Beam Standard) comes close, but the Josephson Junction is a direct translation of frequency to voltage. It is also an instrument in quantum computing. I will offer a page for your consideration: http://www.ptb.de/en/org/2/Inhalte/J...n/_josephs.htm Anticipating your objection that the frequencies involved are not in the 80M band; I would offer that is satisfied easily through frequency multiplication. (The Atomic Clock does this in reverse and no one complains about that.) Anticipating your objection that this is not done at room temperature; true, the junction is cooled far below what is available to you - but is this about your limited resources, or is it about being done? Don't join the legions pleading destitution (poverty) as that might migrate into the metaphors and analogies for a very poor (sorry for the pun) outcome. Theorical/extreme cases are welcomed too but... to rebut normal/standard situations? I do not believe you has blocking Cecil posts, no no, you say it = we have a lot of psychoanalysts he one of them are whispering to my ear just now, you really like him, remember TV series: "The odd couple"? :D Yes, I do block him. There are traces that sift through the cracks, but that doesn't elevate them to poignancy. Again (do I have to repeat this?), this is about S+N/N. "The Odd Couple" is a good cultural reference. I would suggest (and I hope you have access to) "House." Cecil is among those who cannot be trusted to write on the white board. If you don't have TV access to this series, try an episode from: http://www.hulu.com/search?query=house&st=0 You write and understand English quite well, but if listening to it is not easy, I am sure that watching 10 minutes around that white board will give you enough "body language" to translate the psychology easily. ..... (You see?, I'm lost with some interesting sentences such "However your VSWR may vary, no Standing Waves were interfered with in the making of this response." If tomorrow I find my london friend I ask his helping to translate better your entire post :) ) This might be lost on your English friend too, because it constructed with cultural references (it is suppose to be bad form to have to explain a joke - but here we go): "However your VSWR may vary" is a variant on YMMV that you may see as shorthand. It means Your Mileage May Vary. It is a reference to how car gas performance was reported by those who sold cars. They would quote government tests that were generally optimistic, and the real experience would disappoint customers who saw poorer results. The customers would complain to the vendor. Thus the vendor would qualify with "the government reports this car gets 50MPG on the Highway - but your mileage may vary." Thus the usage of YMMV is a cultural joke indicating disappointment was likely. " no Standing Waves were interfered with in the making of this response." is a variant on the disclosure you see at the end of movies: "No animal was harmed during the filming of this movie." You will, no doubt, draw out the meaning of Standing Waves, interference, and response as being related to soothing those people who cry uncontrollably when they see the movie "Bambi." We have a similar class of sob-sisters (your English friend should be able to translate that). 73, and now being 23:31 I will take my girlfriend LU2ET to a night trip motorcycle by the city. Well... 2ET has been my XYL for over thirty years :) Have you a really nice motorcycle as Cecil? eh? I drive an engineer's car with a rotary engine (pistons suck): Mazda RX-7.
