wrote: Time never changes in our frame of reference. I agree with you. Time never changes in our subjective frame of reference exactly as the center of the universe never changes in the 17th century Catholic Church's frame of reference. Word salad. There is no such thing as a "subjective frame of reference". But our subjective time frame of reference is no more valid than the Catholic Church's subjective space frame of reference was - and maybe even less so. Word salad. There is no such thing as a "subjective frame of reference". You might even be the reincarnation of one of the Catholic priests who condemned Galileo to house arrest. :-) You never tire of bringing up the Catholic Church and Galileo, do you? Sorry, I don't know much about the Church other than they screwed Galileo and you can shake it twice to clean the bore, but shake it thrice and you've sinned some more. Anyway, it appears that either: A. You don't understand what a frame of reference means in physics. or B. You're bored and want to argue for it's own sake. or D. All of the above. -- Jim Pennino Remove .spam.sux to reply. |

Cecil: This has become an impossible argument. And, Richards' comment about paying some attention to staying on topic caught my attention. My point is, with our present state of knowledge and understanding of such things as time and the "mysterious 377 ohms" (not EVEN to mention the permittivity of space) our antenna designs and advancements have stagnated. Yeah, so what? The lever hasn't improved in thousands of years other than in the use of new materials. The same can be said for cannon and revolver design since about 1900. When was the last time you heard of advancements in the design of milling machines, lathes, fork lifts, the CRT, and any number of things? Technologies mature, get over it. Oh, and 377 Ohms and the permittivity of free space are not "mysterious" to the educated. snip remaining -- Jim Pennino Remove .spam.sux to reply. |

wrote: The human defined unit of time called the second is simply a way to measure time. The universe doesn't age one second with each passing second of subjective-arbitrary Earth time so what good is any estimate of the age of the universe? A scientist living somewhere else in the universe will get an entirely different result. One of the cornerstones of science is that if the results are not reproducible everywhere at every time then they are invalid. Nonsense. The universe most certainly does age one second with each passing second within the frame of reference where the second was defined. If a scientist living somewhere else in the universe uses the same frame of reference, he will get the same result. If he uses a different frame of reference, he will get a different result which can be converted to our frame of reference and the result will be the same. GPS satellites are in a different frame of reference but manage to provide results that agree with our frame of reference. What I really don't understand is why understanding frames of reference is so difficult for many evidently otherwise intelligent people. -- Jim Pennino Remove .spam.sux to reply. |

The Awesome Razor
No reason for saying "percieved". It was a very real and obvious
problem. On Jan 23, 3:56 pm, "art" wrote: The reason for the original design was because in rarified locations such as Quito, Equador the yagi produces excessive corona at the element tips. The quad solved the perceived problem. I say perceived because the corona will eat away at the yagi antenna element lengths , In a hazardous area the quad is more suitable than any other antenna.

How about we put one up over a salt marsh, would that be safe enough to not endanger the population? Rick K2XT- Hide quoted text -- Show quoted text - |

wrote: One defines a standard and works with the standard. The point is that our "standard" second changes with velocity and we have no idea what our velocity is or was or will be. We are defining our average velocity as a constant without any evidence whatsoever to support that definition. That's no different from defining our average position as the center of the universe. You really need to try and get your head around relativity. And understand that what you are worried about doesn't matter a whit. However, this will likely degenerate into one of your famous "Cecil against the world" ****ing matches as usual. tom K0TAR |

A frame of reference which is in error is subject to that rule ... end of story. Babbling word salad. Then again, there are those without a snowball's chance in hell of ever understanding what frame of reference means. -- Jim Pennino Remove .spam.sux to reply. |
