Are they afraid to use a real name or callsign?
Afraid they may get sued for libel? I wish we could get all these anonymous remailers shut down. I'm sure they have some good uses, but people like Wiseman use them to harrass people. And it's gonna catch up with him. Sooner the better!!! Lloyd Davies - Time Lord and Talk show host "On the Domestic Front" http://groups.yahoo.com/group/domesticfront/ |

Hey! Anybody ever told you a preposition is a terrible thing to end a
sentence with? ;^P -- Stinger "Stagger Lee" wrote in message ...

Another good one, Frank!

When we arrived, I asked someone out in the common area for directions. "Can you tell me where the registration area is at?" I asked. He said "Sir, at Harvard, we do not end a sentence with a preposition." "OK. Can you tell me where the registration area is at, asshole?" (OK, I stole the story, but it's a good one ![]() Dave KZ1O |

SL,
To be 'consistant' in your Logic of using "Five Significant Digits": Would be: 120.00 V * 1.4142 = 169.704 Rounded 'down' to 169.70 NOT: 120 V * 1.421356237~ = 169.705627484~ Rounded 'up' to 169.71 Regardless Either Answer: - - - When 'rounded' to Whole Numbers the Answer would be 170. But then again, how does one really, truly, factually claim that "170" is 'round' to "Two Significant Digits" using Three Numbers ? ? ? hnyccot ~ RHF Hey, Numbers!

But then again, how does one really, truly, factually claim that "170" is 'round' to "Two Significant Digits" using Three Numbers ? ? ? Hmmm... those answers are fine (close, but only that) for textbook examples of how to convert numbers, assuming a pure sine wave. They are great for teachers (and those who have learned only from teachers). In real life, if the answer comes out to 169.705627484, remember that the real-world value can plus-or-minus a few volts. It's a lot like saying that "Observers estimate that the fire was at least a mile, or 1.609347219 kilometers, away." Have you ever done it? I mean, looked at a scope, stuck the probe in the wall socket, and measured the line voltage? Is it a pure sine wave? (answer: no, and no, I suppose). It's a complex power waveform. So, do you know how to integrate a complex waveform such as a sine wave with various spike interference present, in order to know the true RMS? Does it even matter, if you are lighting up a light bulb? By the way, this thread was so distorted that I don't know who is who, and it is obviously a ****ing contest, so if I mistakenly pointed out the idiocy, or replying to the idiocy, I apologize ahead of time. The good part is that one or more of these guys will flame me without facts, and that will answer the original question. Is it about: * spelling (typos) * significant digits * ham radio My guess is: yes, yes, no. All the best, and 73, Dave KZ1O |
