wrote: Quantum theory describes electromagnetic energy as being divided into a series of packets called photons, so (total energy in a stream of photons) = (number of photons/second) x (energy of individual photons). Energy is not expressed with a time in the denominator. The standard quantum theory expression for energy is eV - time is wholly absent as it should be. This also means that EM energy doesn't exist in pure sine-waves EM theory does not exclude the classic description of pure sine waves. This is not a neither/nor situation. - the waveform is actually built up in steps, very much like digitized audio. This appears to be the beginnings of a description about to fall off the edge. What waveform? This is a conceit of time. The step size is the energy content of one quantum. No, the step size as you describe is the potential difference of quantization, an engineering term, not a quantum mechanics term. It is quantisizing an amplitude to construct the wave in a time domain. Quanta is the complete wave in a frequency domain. The transform from one domain to the other is classic Fourier. His analysis revealed that one unique energy (a single frequency) can be decimated into many components (amplitudes over time). The transformation is fully reversible (many amplitudes over time turned back into one single frequency) without any information loss. Mixing the two as being one analysis, corrupts it. Time is not a factor in energy and cannot be drawn into its discussion through transforms that mix topics. The question is: are those steps noticeable enough to be important? For light and shorter wavelengths, the answer is often Yes. Quantum theory was developed to explain observations like some kinds of light being emitted in a series of sharp spectral lines, which cannot be explained by a wave-only theory. Instead, it has to be thought of as being built up of individual photons/quanta which can only have certain "allowed" energy levels. There is absolutely no distinction between "allowed" energy levels and resonance which allows only certain frequencies. Resonance has been historically correlated with circularity, and every instance you site above is found in the change of orbitals - circular, harmonic motion. A photon is emitted in the cM band when an electron orbiting a Hydrogen atom flips its magnetic pole. This event is vastly below the short wavelengths you describe by a million-fold. A good number of correspondents here are fully capable of detecting this event with commercial gear already suitable for the Ham market. They could have done it 50 years ago too. This is a quantum event, it is expressed with a classic quantum energy, and it is resolvable as being important (insofar as "importance" is a subjective, not quantitative quality). It is certainly noticeable and is not artificially constrained by scale. 73's Richard Clark, KB7QHC |

Look at section 1.5 on page 17. The section states: The Maxwell equations are differential equations applying locally at each point in space-time (x,t). By means of the divergence theorem and Stoke's theorem they can be cast in integral form. [... a few sentences later...] Then the divergence theorem applied to the first and last [Maxwell] equations yields the integral statements... The first is just Gauss's law... --John yes, referring to all 4 Maxwell equations you do have a 't' dependency. however, even equations 1.13 and 1.14 referred to by your quote have NO time dependency in them. the equations on the next page,1.15 and 1.16 have the time dependency that the 't' in your quote refers to. remember, those integrals are NOT integrals over time, they are over the surface or volume. |

... 73's Richard Clark, KB7QHC I don't know ... A digitized/stepped wave sorta' makes sense. If you have an "amplitude" of one photon, then you add another, and yet another, etc. it would tend to look "stepped" at some point--and, since no one really knows, let's reserve the final determination ... Right now, "quantums" are kinda like "nauga hide" (or, naugahyde) to me ... You DO know about naugas' right? My couch and chair and covered with their hides ... grin Regards, JS |

As I stated before, this chapter deals with electrostatics so the time dependence has been dropped. However, the fact remains that Gauss's law is the integral form of the first Maxwell equation, which holds for an arbitrary space-time point. Unless you reject the first equation, namely div E(x,t) = 4 \pi \rho(x,t) or the divergence thereom, you have to accept the fact that \integral_S E(x,t).dA = 4 \pi \integral_V dV \rho(x,t) which is Gauss's theorem. This is my last post regarding this subject. --John |

I will make one last effort to to set the record straight. In volume II of the Feynman Lectures on Physics, the title of chapter 15, section 6 is "What is true for statics is false for dynamics". The 5th paragraph of that section states "Gauss' law, [eq omitted] remains...". Also in that section, he has a table (Table 15-1) that contains two columns: FALSE IN GENERAL | TRUE ALWAYS (true only for statics) | ------------------------------------------------------ Coulomb's Law | Gauss' law [...] | [...] Then in chapter 18, section 1 paragraph 3 you will find the statement: "In dynamic as well as static fields, Gauss' law is always valid". I do not think I can make it any more clear than this. thank you for not continuing to prolong the misinformation in this thread. Do you also accuse Feynman of spreading misinformation?

I don't know what Country you come from but I apologise that the baggage associated with me was then dumped upon you and I fully understand your action of withdrawal. Thanks again for your efforts and I trust that you will not see this as sign of a new America emerging. It is certainly not the America I envisaged some forty years ago when I arrived. I think it is best that I to withdraw . Sometime it takes a hundred years before science is permitted to move on. A similar thing happened to George Green of Nottingham U.K. and only reemerged in full by the presentation by some body else who received the acreditation. Best regards Art Unwin KB9MZ...XG |

While most of us sympatize with your condition, but your drivell is getting beyong pathetic, you dumping on America is picture of your messed up judgement and your "evaluation" of people here is just reflection of who is messed up. If you can't get over losing your colonies, or superiority of colonist inbreds, you are free to go back, Eurabia is waiting for you and will undoubtly recognize your genius (of calling reflector - director, and having patent to prove it) and award you cross of the empire or something. Just what the heck is your "Gausian" contraption suppose to get me that all other known antennas or my designs don't? Lousy pattern with three lobes over perfect ground and 6 dB F/B at 200 MHz???
