So, the mass of the particle at 90% the speed-o-light is 10 times that of the particle at rest. It doesn't matter what particle. Do I get a gold star? That doesn't work for photons which are particles with zero rest mass. -- 73, Cecil http://www.w5dxp.com |

On the contrary, radiation is photons which indeed do have mass when traveling at the speed of light, which radiation does. According to Einstein, anything with energy has mass equivalence - especially photons. But other than that, nothing with mass can travel at the speed of light. You can have one, or the other, not both. 73, ac6xg True, travel is something less than the speed of light Art - In what medium? Remember that the speed of light is different in different media. |

Light can be bent by large bodies of mass. Oh sure, they have a "perceived mass", don't they?; I mean, we seem to be able to measure it, don't we? How do you know it "exists ALL ITS TRAVEL TIME", what makes you think it is not constantly oscillating for energy to mass ... and it is ONLY the average of that which we are REALLY measuring ... can you prove that, well, CAN YOU? Can you provide any relevant data here to prove it? Any URLs? Any quotes from famous physicists? Any psychics? Have you consulted Art? again-innocent-smile But then, you ever try to run along side of one of those photons and measure it? I mean, this is how you really gain a critics respect (heck, you'd even gain acknowledgment from the arrl, well, most-likely--well, I think you would--IMHO anyway, etc.) -- now, the question to separate the men from the boys -- now, have you? pleasant-innocent-smile Geesh! looks-out-window Regards, JS I should have used black holes as my example. One only needs to accept that black holes exist in order to believe that gravity affects the property of mass inerent in light ;-) - Maybe it's not gravity that bends the light that comes near black holes. Maybe it's something more sinister like extremely strong magnetic forces. . .. Maybe I just don't have the faith necessary to believe in black holes (tongue firmly in cheek). |

Until this is corrected we will never have continium of discussion between hams on antennas.It is not a mystery anymore so why do the ARRL avoid it like a plague? Art Art: You have written 2,947 posts to RRAA, and at least 2/3 of them contain a reference to " equilibrium". Numerous people have asked you to define or at least explain your usage of the term. So far, you have not done so.Actually, you have either diverted the question, or told questioners to do their own research. Your posts show that you know nothing about how antennas work, and suspect very little.Why would ARRL correct something that's perfectly fine as is??? Mike W5CHR Memphis Tenn Mike I know more about antennas and radiation than you think ! For instance, equilibrium demands that charges do not move laterally along an antenna when in equilibrium Without equilibrium charges do move along the surface of a radiator and Newtons law of parity demands that charges are moving thru the CENTER of the radiator thus encoundering just copper losses. Thus for a radiator that is not in equilibrium has three resistance 1 Radiation resistance 2 outer resistance 3 Inner copper resistance. Equilibrium is nothing more than the enforcement of Newtons law of parity. This is so simple to those who work from first principles for themselves instead of being lemmings. Correctness is not always determined from a poll Regards Art - I've heard of Newton's laws of motion, but not Newton's law of parity. Newton dealt primarily with motion, mass, and such. Electromagnetic radiation hadn't even been discovered when Newton was alive. Electromagnetic radiation does not behave the same way as matter, which is described in terms such as momentum, inertia, accceleration and such. Mike Einstein changed course in study because he could not solve the description of the weak force which I see as foucalt current. Knowing this Einstein would be proud to stand up as state his thoughts on Universal law has now been proved forget. You cannot parcel laws based on a particular subject. Universl laws are just that. UNIVERSAL. What on earth does parity mean in the U.S.? Art - The equal and opposite reaction thing applies to massive bodies and motion. It's all different when talking about relativistic speeds for things such as electromagnetic radiation. |

I didn't say photons have zero mass; I said electromagnetic radiation (EMR) has no mass. EMR exhibits both wave and particle properties. When travelling at the speed of light, it exhibits wave properties. |

Where in the world did you get such irrational ideas? I have an Engineering Physics degree from a university program that is an ABET certified engineering program. After your latest posting, they may de-certify your university's program. Exactly what university was it that taught you that photons traveling at the speed of light have zero mass? -- 73, Cecil http://www.w5dxp.com Cecil, this sounds like a regular poster David.Perhaps he is pulling your leg with his nonsence Art - No. I'm not David; and I just started posting here. I'm not trying to pull anyone's leg with nonsense. I'm trying to participate in a discussion where people have different perceptions and understanding of physics. Isn't that what causes us all to learn and/or change our perceptions on occassion? It seems that the last vestage of a lack of answers to a point is to mount a personal attack. Your refusal to answer the salient point and instead mount a personal attack means your ability to listen is totally stopped. Discussion over. |

When travelling at the speed of light, it exhibits wave properties. When traveling at the speed of light, it exhibits particle properties. It has been about half a century since experiments proved that light waves are bent by gravity thus proving that electromagnetic radiation has mass. That idea was postulated in 1915. Did you get your degree before then? :-) -- 73, Cecil http://www.w5dxp.com |

Took a lot of posts to get to that point. JB I apologize I have been nailed to the cross so many times I tend to bundle things together. When I started I zeroed on equilibrium as a start because existing laws state that if a charge is moving on the outside of a radiator then there is movement on the inside of a radiator Now that is not in the books. Why is that? However discussion went away from the intent of the thread. equilibrium with respect to radiation. O well another try later Regards Art |
