I've told you that doesn't work. What you need is a fibre optic, LED and small battery. You can make a hula hoop, necklace or bangle, as long as you twirl the LED around as the light travels along the fibre you will not age as much. You are not permitted to observe c+v, its a LAW of physics. Now get busy making one and sell it to Michael Jackson. If Michael gets too tired twirling, fit it to his desk fan. I take 50%, it's my idea, you do your share and we'll be in business. Androcles |

To be a crank, you have to abnormal like me. I can't possibly support normal people aspiring to crankdom. Here is an example of how to fish. The needle is the hook, the plate is the sinker, the line is the one I spin. Then you spot a normal fish with a Ph.D. swimming and cast your bait, which is swallowed hook, line and sinker. Reel it in slowly if it's a big fish, or land it fast and throw it back if it's a minnow. "Timo Nieminen" wrote in message ... | On Sat, 8 Oct 2005, Androcles wrote: | | [incorrect attributions corrected] | | [Nieminen wrote:] One very traditional way to measure permittivity is using a parallel plate capacitor. Neglecting edge effects, the capacitance is C=eA/d where e is the permittivity, A is the area, and d is the distance between the plates. Measure the capacitance, and you have the permittivity. [Nieminen wrote:] Given that the electric field of any charged particle extends to an infinite distance (or, if the particle came into existence a time t ago, extends to tc), then there isn't any empty space anywhere in the vicinity of matter. Oh, look, there's light in intergalactic space! Look, the microwave background radiation is everywhere! Androcles casts his line: Ok, Now reduce the area to a point, say one atom at the end of a needle. Apply some large voltage (say 1,000,000V) between the needle and a plate (any area). Start with d large, say 1 kilometre. Gradually reduce d. What happens? Nieminen: Well, the connnection between your question and the quoted text is unclear to me (other than both involving capacitors), and the connection with our previous discussion where you claimed that permittivity (e) and permeability (m) of free space are zero, and that the Maxwell equations other than (the modified) Ampere's law are correct, is also unclear. What is your point? Androcles: To try to clarify what is unclear. Nieminen: Anyway, I'd say that about the same thing would happen if you brought them together in empty space as if you brought them together in air, until the fields became large enough to get fun stuff like arcing, ion wind etc. Androcles cranks his reel: You would, huh? That ends the discussion, then, my TV needs a vacuum to operate. See? Fish landed, too small, thrown back in the pond. Easy.

Not at all. The Chevy may observe the Ford to have no motion.
The Ford may observe the Chevy to have no motion. But at end of 1/4 mile, the fuel remaining in the tanks will indicate the race car with less mass. Metaphysical musings don't get us any closer to the notion of time than a couple of kids can measure with a fuel can on a Sunday afternoon. Sue... But neither the Ford nor the Chevy can make an observation in less than Planck time. You have 3 things going on here. 1) Observability of time 2) Observability of length 3) Observability of motion, which is a composition of (1) and (2). Ford observes Chevy, and Chevy observes Ford. But this requires t PlanckTime, otherwise they cannot make an observation at all. LEFTY can't aspire to crankhood by agreeing with the majority like that. His idea is likely to get a Nobel Prize. Thanks for the demo, Sue, but I'm not sure he'll ever be one of us. Androcles. Nobel would be in big trouble today for making dynamite. I'm not sure that I could ever accept money or medals from someone who so obviously flaunts the law. The world has surely been turned on it's head to deify a man who does such things. |

"Is it true," she asked, "that your daddy had a car with drawings all over it?" Carl Feynman acknowledged that there once was a 1974 Ford van, California license plate "Quantum," covered with the pictograph-like Feynman diagrams for which his father won the Nobel Prize in 1965. "People would sometimes come up to us and ask, 'Why do you have Feynman diagrams on your van?' and we'd say, 'Well, we're the Feynmans.'" http://web.mit.edu/newsoffice/1998/feynman-0520.html Sue...

OMG that is funny.
I saw a documentary about Richard Feynman, and also remember his investigations into Challenger disaster. I think that he's pretty much the consummate 20th centiry scientist. And I think that if he were here, posting on this thread, he'd probably give a pretty good argument against what I'm saying simply because it seems ridiculous to treat nonexistence as a physical phenomena. I think that even Einstein felt that way if I'm not mistaken. Feynman's math seems to make a tenuous dance around the idea of nonexistence, always careful not to step on it. |

If the universe doesn't exist, then we don't need to study it. If the universe does exits then we must be, at the very least, some kind of electrical disturbance in it. Our opinions OTOH, probably don't have as much substance. :-) Sue... |
