On which, I respond; "Why would the mere length/phasing of elements on an antenna be able to cause one to act as a mirror (the one longer than DE) and the other as a director (the one shorter than DE)? It has to do with the phasing of the photons and the spacing of the elements. The phasing+spacing results in constructive interference in the direction of the director and destructive interference in the direction of the reflector referenced to the driven element. The length of the element affects (and effects) the phase of the re-radiated signals from the parasitic elements. Using EZNEC with two identical driven elements, one can control the direction of maximum radiation simply by adjusting the phasing of one of the driven elements referenced to the other. Reversing the phasing reverses the direction of maximum radiation. -- 73, Cecil http://www.w5dxp.com |

Cecil: The "approximations" which EZNEC accomplishes, may, or may not be real--indeed, much of what these "antenna tools" have told me appears to work in reality ... I CANNOT and do NOT say these tools are without value. However, when you have an "un-ponder-able unknown", such as the ether, and you see NO mention of it in mathematical equations, no allowances made for it, no affects/effects noted for it--indeed, when you see a public ignorant of it--don't you grow a bit suspicious? I mean, and according to Einstein, every bit of matter we can possibly view was torn asunder from it! It is real, we only exist in an altered and unnatural state--along with our antennas. Why has ether become synonymous with "kook?" It should not be; why does it seem to have been missing from everyones physics books but mine? My books just stated it was as it appears to be--unknown, but a real thing--I took it to be a thing future minds would "discover"; that its' promise was a better understanding of the world, in the future. Now, we can come up with a lot of explanations about a lot of things--might it not help to give this KNOWN/REAL thing some thought; ask some questions on its' possible interactions with our antennas? If my wonder-ings about this ether cause me to be a marked man and easily dismissed--so be it. And, I would prefer to read and experiment in this direction than jump to the conclusion our antennas are emitting photons, others may feel free to disagree with me and suffer no evil intentions from me. Whatever is the reality of this matter, let's pray it quickly becomes known; either way I will be just as thrilled. New discoveries, which we can get our minds wrapped around, speak of new and interesting phenomenon we can manipulate to our benefit. And, debate is interesting ... Regards, JS |

Why has ether become synonymous with "kook?" From Wikipedia: "Einstein in later years proposed calling empty space equipped with gravitational and electromagnetic fields the "ether", whereby, however, this word is not to denote a substance with its traditional attributes. Thus, in the "ether" there are to be no determinable points, and it is meaningless to speak of motion relative to the "ether." Such a use of the word "ether" is of course admissible, and when once it has been sanctioned by usage in this way, probably quite convenient." Ives was the first to positively measure the effect of speed on clock rates. He wrote in 1940 in a paper in Science: "I have considered the popular claim that the ether has been "abolished" [...]. Reverting to experimental findings I have reviewed the experiment of Sagnac, having in mind the claim that the ether can not be detected experimentally. I have asserted that, in the light of the experimentally found variation of clock rate with motion, this experiment does detect the ether." -- 73, Cecil http://www.w5dxp.com |

The old bull dozer refused to start and I hunted all over the place for a can of ether... Didn't detect one either... Mind you it was 92 degrees yesterday and rooting around through the toolshed with the sun beating on the steel roof for ether was no picnic... I doubt that Michaelson and Morley worked up that much sweat looking for it... denny |

Yes, that annoying fact, clocks slow when you place 'em on jet aircraft, refuel the aircraft in flight, and make a few trips around the circumference of the earth. In my present state of thought, this directly relates to the speed of light; further, I suspect, the ether is responsible in establishing the, seeming, barrier of the speed of light. As you approach the speed of light, things are not linear, you must apply magnitudes more energy without corresponding gains in speed. And, although I tend to believe the math which "proves" this, it ends up just another thing I fail to completely be able to wrap my mind around. But, it seems at the speed of light, traversing the ether with matter offers such a resistance to the speed of matter, any further increases of speed are impossible--no matter the amount of expenditure in energy ... At this point, I am just happy to be in the company of others who will, at least, accept the possibility of the ether, and the possibility it can/does have real effects/affects on our material world.

I listen, we move to the second level ... ... Regards, JS This: "Einstein also said that behind every great theory there is a simple physical picture that even lay people can understand. In fact, he said, if a theory does not have a simple underlying picture, then the theory is probably worthless. The important thing is the physical picture; math is nothing but bookkeeping." And this: Amrit Sorli: Einstein stood on the point that the notion of "space" designates "gravitational ether", which is a physical reality. "With regards to the general theory of relativity, space cannot be imagined without ether", says he in his "Ether and the Theory of Relativity". According to Einstein, gravitational ether does not have the same properties as ponderable matter, that is why it cannot be described by notions such as "time" and "motion" . .... Time is not a physical reality, the past and the future exist only in human reasoning. Changes take place "here and now" in the gravitational ether. From he http://www.mu6.com/einstein.html I am sure most will find it highly interesting and enlightening ... Regards, JS |

Continuing themes of their friends and relatives populated this series with such stories as the "strange attractors" of kites and trees, or the wave function of a football that couldn't be kicked. The illustrator was purported to be one Eisenstein, but this was later found to be erroneously inferred from earlier cinematic work with similar themes found in "Aleksandr Nevskiy." 73's Richard Clark, KB7QHC |

G And who was this Schroedinger guy anyway? Ed, NM2K The point Schroedinger was trying to make is that in the absence of information, there is no way we can absolutely know something. The very act of measuring or observing something causes the wave function to collapse and reveal an object's position, speed or some other state we are trying to establish. Opening the box and asking the cat seems eminently reasonable. The cat is never actually in a quasi alive/dead condition. In it's own 'universe' (box) it is either alive or dead. We cannot know which without opening the box at which point the two separated 'universes' collapse into one. Prior to opening the box it is necessary to consider both options alive or dead as a possibility but there is no third case where the cat is both alive and dead at the same time. The physical laws in our universe do not appear to allow for objects larger than a buckyball molecule of C60 to exist in quasi states. Trying to establish whether individual photons or electromagnetic waves are emitted by an antenna suffers from the same difficulties. The very act of trying to establish what is being emitted will collapse the wave function of the photons or electromagnetic wave to reveal one or the other, but not both simultaneously. Mike G0ULI |
