In the UK, until around 1970, I think all cars had positive 'ground'. I would be very surprised if USA cars were any different. I believe that the reason for this is that it was supposed to reduce corrosion of the electrical connections. The change to negative ground seemed to coincide with the introduction of more equipment with NPN transistors (which were generally designed to have a positive power feed). For a few years, many car radios had a polarity switch, and if you moved a radio from your old +ve ground car to you new -ve ground car, you had to remember to change the switch over. I recall one works colleague blowing up a rather good radio when he didn't. If your car had the old dynamo generator (which once they invariably did), it was usually very easy to reverse the polarity. To do this, you simply had to give the field winding of the dynamo a 'splat' of reverse polarity (which reversed the residual magnetism) and (of course), change over the battery connections (which sometimes entailed fitting a longer battery ground cable). As the starter motor was series wound, it still turned in the same direction. -- Ian |

Heavisde was en engineer and Pointing was a teacher: "Poynting and the Nobel prizewinner J. J.

I also see that the quote, shown above, is from a CB site and not from an amateur radio site.

While there may have been some exceptions in the very early days, all the cars I've seen back to the 20's were negative ground. I owned some positive ground British cars and there were "challenges", like arguing with US mechanics that no, the battery wasn't backwards and putting in anything but a British radio or electric fuel pump. |

It is not easy to explain physics to children and engineers. Actually, it is quite easy to teach normal children and engineers, but it would be impossible to teach anything to a moron like you.

S* You are an ignorant, babbling, ineducable idiot who knows absolutely NOTHING about how ANYTHING works. You don't even understand what an antenna is or the difference between an electric field, a magnetic field, and an electromagnetic field. Electrostatic and magnetostatic fields are created by DC. An antenna is a device that converts the AC electrical energy at it's teminals into electromagnetic energy which radiates from the antenna and also coverts the electromagnetic energy which antenna intercepts into AC electrical energy at it's terminals. That is ELECTROMAGNETIC energy, not magnetostatic nor electrostatic energy. From http://en.wikipedia.org/wiki/Biot%E2%80%93Savart_law "The Biot-Savart law is fundamental to magnetostatics, playing a similar role to Coulomb's law in electrostatics. When magnetostatics does not apply, the Biot-Savart law should be replaced by Jefimenko's equations." What that means, you babbling idiot, is that Jefimenko's equations apply to antennas, not the Biot-Savart law or Coulomb's law. Jefimenko's equations were first published in the 1960's so anything written before then is essentially irrelevant to a discussion of antennas. Since an antenna is defined in terms of it's terminals, anything that may be connected to the terminals, such as a balun or a transmission line, has NOTHING to do with what the antenna is or how the antenna operates. What that means is that ONLY the voltage at the antenna terminals effect what is going to happen, NOT how the voltage got there. How many antennas have you built in your lifetime? Why do you refuse to answer the question? Is it because you have built zero antennas and you are trying to say all the people that have successfully built hundreds that they are all wrong and you don't want to admit you are an ignorant, inducable, idiot? Why can't you obtain and read a university level textbook on electromagntics in any language? Is it because you are too stupid to be able to understand the material? |

I think the rectenna was mentioned by Szczepan several months ago - are we going around the loop once more? Is it worth commenting about scientific method, theory and fact? I'll say that reading Szczepan's postings makes a good spectator sport. 73, Ian. |

To have knowledge means know the facts not theories. We will probably never know all the "facts" - the best we can do is become less ignorant. All of our models of reality exist in human minds filtered through human senses none of which are perfect. For instance, entangled particles seem to violate the spirit of the speed of light limit, yet they have been proved to exist by experiments. And how is it possible for a huge carbon Buckyball to pass through two slots at the same time and interfere with itself on the other side? Seems to me that the particle is creating a wavefront in the structure of space. The best models are the ones that best match the latest experimental evidence. Some of yours do not match the latest experimental evidence at all, i.e.. seems that you are deliberately choosing to remain ignorant (or just pulling our legs). -- 73, Cecil, w5dxp.com |

"Ian Jackson" napisal w wiadomosci ... Every time yet another post on this subject arrives, I can't help thinking of the limerick about the 'Young man of Devizes' (a small town in Wiltshire, England). Those who have no idea what I'm talking about can Google. Perhaps there's a similar one about a radio amateur whose dipole had unequal wire sizes? "End-Fed Center-Fed Dipole (AKA Coaxial Vertical Dipole) Really, that description is correct. Primarily constructed with coaxial cable the one half wave vertical dipole is fed from its bottom but the coax shield is left in place only up to near the center point (about ź wave but the exact end point for terminating the shielding is determined by tuning) which becomes the actual "feed-point" ergo, the description. The center conductor continues up for about ź wave past the point of termination of the shield." From: http://forums.qrz.com/showthread.php...ter-Fed-Dipole Are the wires equal or unequal? Is it dipole, monopole or "dipole"? S* |

MAY instead "Without of any doubts";. Of course, technical authors avoid absolute assertions because they know that almost all knowledge is proven inaccurate sooner or later by the additional acquisition of human knowledge driven by finer-tuned experiments. What you don't seem to understand is that technical knowledge builds upon technical knowledge so that the latest theories that support the latest experiments are the best "knowledge" that we have so far. Without the 19th century giants in the field of physics, we couldn't have progressed this far, but those giants were simply ignorant of 21st century physics. The Giants discovered in XIX century that light is the oscillatory flow of electrons. The "Giants" were wrong, light is no such thing, and you are a moron. Today we too, are still ignorant to a certain extent, but hopefully less ignorant than 19th century folk. In XX century was done the first rectenna: "A rectenna is a rectifying antenna, a special type of antenna that is used to convert microwave energy into direct current electricity. " In XXI century are the optical rectennas. Irrelevant to anything to do with the nature of light. But the first were the crystal radio: "The simplest crystal radio receiver, employing an antenna and a demodulating diode (rectifier), is actually a rectenna". From: http://en.wikipedia.org/wiki/Rectenna Irrelevant to anything to do with the nature of light other than to show light and radio waves have the same properties. You wrote "latest theories that support the latest experiments are the best "knowledge" that we have so far". But there are plenty of theories. Which one is the best? Generally, the latest ones which have more experiments and data to back them up. To have knowledge means know the facts not theories. To be Szczepan Bialek means to be an ignorant, ineducable, moron. You are an ignorant, babbling, ineducable idiot who knows absolutely NOTHING about antennas or how they work. You don't even understand what an antenna is or the difference between an electric field, a magnetic field, and an electromagnetic field. An antenna is a device that converts the AC electrical energy at it's teminals into electromagnetic energy which radiates from the antenna and also coverts the electromagnetic energy which antenna intercepts into AC electrical energy at it's terminals. A rectenna is simply an antenna with something that acts as a diode at it's terminals to convert the AC to DC. How many antennas have you built in your lifetime? Why do you refuse to answer the question? Is it because you have built zero antennas and you are trying to say all the people that have successfully built hundreds that they are all wrong and you don't want to admit you are an ignorant, inducable, idiot? Why can't you obtain and read a university level textbook on anthing in any language? Is it because you are too stupid to be able to understand the material? |

The papers of Giants are now available. Try to compare the papers by Heaviside-Pointing and Dirac. Dirac was an engineer so he was tought on Heaviside-Pointing's EM. Dirac never even mentioned EM.
