Then same thing with plain rod. Both would be galvanised. The roughness of the gal would be the same on both. If one had a fast scope one could use just one length of threaded rod. Then it would be good to gradually grind away the thread & see how much dispersion happens. Until there is no thread & no dispersion. --- End quote --- Having the receive and transmit ends of the rod would allow the fields from one to couple with the other, the (much shorter than circumference of the circle) length of the scope leads would also add a means of direct coupling between transmit and receive end. So, perhaps you take measures to limit their effect, but why intentionally construct an experiment knowing full well that the effect you intend to measure will be swamped by similar effects of a different mechanism? Why not remove the effects by design? Galvanised finish is not a well controlled process, the surface is very "complex", maybe over 100 feet it will average out to a 'mean' effect, but that would be relying on a linear effect - it won't be linear. Gradually grinding away the thread (assuming you're not re-galvanising each time)... same problem, it isn't a very controlled process, affecting lots of things at once. How would you control the effects of 'ground' with your circular experiment? Would there be something continuous and metalic beneath? --- End quote --- I suppose that the rods would need to be suspended or supported somehow so no shorts. And well away from ground. But, electricity is primarily due to electons that propagate at the speed of light. And induction happens at the speed of light. But as long as there was a clear signal that can be timed, any noise & crosstalk & coupling & radio would are unlikely to be a problem (unless u are like alphaphoenix & have a heavy steel frame under your table top experiment) . Like adx says, dont worry too much, just do it. |
| SandyCox:
Since the electon is a "surface hugging photon" it will follow the thread of rod. This thread forms a spiral. So the finer the thread, the longer the electon will take. |

If the signal were made up of many photons taking many paths, the result would be a spread, you would need to study much more than a time delay and would need to resolve a fair amount of detail. So... another test, if I had an air-gap between a conductor and insulator, your electrons would still be able to travel as if unaffeted by the insulation... because there's an air-gap? What about if I had a wire with bands of insulation spaced periodically along its length, I could form bunches of electricity because it travels much faster in the uninsulated sections and get congested in the insulated? |

Actually Einstein said that light is slowed by the presence of mass. Which everyone ignores. So, light always propagates at less than c, koz there is nowhere in the universe that is not near mass. [...] --- End quote --- When did Einstein say that? Experimental evidence has shown that speed of light is constant with relative distance to massive objects, but time and space dilation happens. --- End quote --- Aetherist has to focus on Einstein because 1) it's a hallmark of crackpots to attack Einstein (see previous articles on this) and use his evolving opinions to highlight some kind of contradiction or hypocrisy (as if Einstein didn't learn new things between 1905 and 1916 or even 1950...) 2) it makes relativity seem like the mad ravings of a crackpot like themselves. "If Einstein could be wrong, I could be right!!!" It is a deliberative attempt to ignore the contributions of the whole scientific community to devising, refining, and perfecting relativity. Let's not forget that Einstein wrote that in 1905, relativity was "ripe for discovery" (if he didn't find it, someone else was going to) and the following individuals contributed to the formulation (list not even exhaustive): Max Planck Hermann Minkowski Arnold Sommerfeld Max Born Paul Ehrenfest Wilhelm Wien Wolfgang Pauli Pascual Jordan Paul Dirac The last one is important because the Dirac equation, a relativistic formulation of quantum mechanics, predicted antimatter. And of course, the whole body of physics that's been done since the 1950s which has predicted a whole host of phenomena implemented into engineering technology. I wonder if aetherist will start talking about phlogiston, Lamarckianism, and miasma. |

Except that they are negative, hence can be influenced (mainly by other electons fighting for a share of the surface area. I doubt that there is much randomness in their direction (except very very early on). Hence i doubt that they would prefer to follow a thread. And i suspect that all whitworth threads increase the lineal distance by the same proportion no matter how coarse or fine. |
