I was thinking in quantic number describing the energy of a typical 100 W 80 m oscillator devolped in one second, representing a quantic number n = 4.3 * 10^28; we know our quanta represents the minimun possible energy of a 80 m radiation AND the minimun "delta" Energy possible for a given oscillator, energy difference between (among?) one quanta an two quanta of 80 m radiation is 2.3 * 10^ -27 J, that difference (my physic book say) it is unmeasurable experimentally (this energy leap (skip?, hop?) it is in the order of 10^-8 smaller that green light leap (in reality my book -Resnick Halliday- give a moving dust particle example with quantic number very much lower than my 80 m example yet = n = 3 * 10^14, they said "we can not distiguish energy difference among n = 3 * 10^14 and n = [3 * 10^14] +1") What it is the ohysical sense of working with magnitudes we can not measure? Nobody (as we know) use (or need) quantum mechanics to deal with (or explain) locomotive movement :) Cecil said "electrons can not travel at light speed, photon yes therefore EM waves are photons", well... EM CAN travel at light speed, then photons are EM waves ![]() ![]() behave as waves and vice versa) have not dead yet (or he died and I found out?). Cecil said: "When the concept of displacement current was invented, nobody knew that RF fields were actually made up of particles (photons) but now we do know". Cecil seem to me as Zarathustra has declared: "ˇWave is dead!" :) Yes, yes, I know some people bring very strange ideas into the forums, but I think it is not necessary argue them with exotic others -even if they are true- because the partner will double the bet and will bring other even more bizarre yet...! :) Well, dont be bothered by my comments, I am joking a little... 73 - Miguel - LU6ETJ |

You are confusing wavelength and quanta (no surprise given the blearing of topic). Compare Green and IR. Is there a correlation on a scale of two that predicts out to a scale of 10^8? Compare Green and deep IR. Is there a correlation on a scale of ten that predicts out to a scale of 10^8? Compare Green and the Sub-millimeter band.

Cecil said Cecil said Yes, yes, I know some people bring very strange ideas into the forums, Indeed. 73's Richard Clark, KB7QHC Dear Richard: On examples we usually start with a visible common data, here I made with a 100 W TX power during one second to gives certain amount of energy, this amount of energy stored in a system (for example a LC tank) gives the quantic number of the system. well... Energy it is Power * Time and n=E/h*v, it easy, it is an electrical cuasi identical example as page 1616 part II Spanih translated Resnick & Halliday book. if for Resnick & Halliday guys is a good example for me is good too :) I do not confussing wavelengh with quanta!, quantized energy it is E=nhv and v it is 1/lambda, how do you calculate E without v in such equation? I don not believe my translations are too wrong! I wrote what book say = "they said "we CAN NOT DISTINGUISH energy difference among n = 3 * 10^14 and n = [3 * 10^14] +1"), (page 1652 op.cit.); where you read: "quantum of smaller energy of a dust particle is measureable"? my text says just the opposite! You say: "OK, so they are talking about the difference in quantum, not energy" I do not know if I am translating well your sentence... perhaps you refer to my missuse of the latin word quanta (plural) instead "quantum" (singular) (in spanish we usually say "cuanto/ cuantos" -not latin-, in english I believe you use latin, sorry by my translating error), but I think not is that. Quantum in this context is "energy quantum", they are talking about difference of energy, that difference it is not continuos but quantized, and each energy quantum is 2.3 * 10^ -27 J, one quantum, two quantum... n*quantum, n*quantum in the system = E (op. cit. page 1615), what is wrong? I am talking about 80 m technically useles quantum treatment, and you say to me: "The limitation is called Quatum Efficiency and the human eye is vastly superior (to all but $1,000,000 components) at rougly QE = 50%." What sort of human eye we use to see 80 m "light"? :) I did not want go out off topic, I claimed quantum mechanics do not help so much to solve TL related problems and give some reasons for that. I am not an expert in quantum physics and I am not going further that my elementary physic book examples. Are they wrong? well... then, I am wrong too :) PSE do not argue with me, I am innocent of charges, read the references... 73 - Miguel - LU6ETJ |

The Cosmic Radiation Background has been measured to about 2.76 K, where the mapping variation (fluctuations of 30 microKelvins) are within the Energy perturbation (contribution) of our Amateur transmissions.

I could not translate this sentence, (sometimes your writings are complicated for me Richard, try Tarzan style or better yet... try as you were writing to Cheeta! :) (I handed the sentence to a friend who lives in England and today said to me that have so many interpretations and did not solve my problem...) "Why do you compare 80M to green light?" Well... I like it! photons born from light, green light it is a central zone of visible light spectrum, and 80 m is my favourite ex- novice band... Look, light has a very rough "texture", light quanta is a very energetic thing, its "granularity" it is high and we easily perceive its quantic nature, 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. 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 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) :) I have a question too, please tell me (I am very curious): why you take every opportunity to bite (sting?) my friend Cecil, ah? ;). I read carefully Cecil writings and I do not find flawings in his affirmations; usually he is very precise and scholar on this matters, sometimes he has an occasional forgivable habit, such his predilection for photons and polished glass things, but I think he has not so "distractive", usually I understand wiich is "his point" to bring another physics areas on the table... I think often we have a little stubborn too :D 73, and thank you very much for your company - Miguel - LU6ETJ |

I could not translate this sentence, (sometimes your writings are complicated for me Richard, try Tarzan style or better yet... try as you were writing to Cheeta! :) Hi Miguel, Fair enough - and sorry for the density of style. (I handed the sentence to a friend who lives in England and today said to me that have so many interpretations and did not solve my problem...) Well, that sentence was more about context than it was about style. I am glad you did not ask your friend to read the thread. "Why do you compare 80M to green light?" Well... I like it! photons born from light, green light it is a central zone of visible light spectrum, and 80 m is my favourite ex- novice band... 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 |
