1. Be careful what you write. Take some time to review what you've written before you hit the Submit Reply button. 2. If you feel you've been unfairly slighted, don't violate the rules by slaming the dude/dudette in public. Just PM the mods (again, this is simply following the rules), and explain the situation. If you're in the right, they'll take the appropriate action. If you're in the wrong, they'll let you know. But I'll tell you this (if you haven't already heart it from either another poster or a mod), posting open-ended complaints such as this in a public thread isn't a very good idea, primarily because reviewing your last umpteen posts is a trivial manner. I can see them, see what else went on that you didn't mention, perhaps come to a totally different conclusion (as can the mods), and if there is any underhandedness... ...Yousa being banished! (Jar-Jar speak) So, just follow the board rules and my initial advice (in line with the board rules). Do that, and you'll enjoy this place! Violate it and you'll live to regret it. - Mugs

Chris,
I didn't get e-mail notification about your text. I read it in BAUT forum before it was deleted, so obviously I couldn't know that it will be deleted. Your assumption about my re-posting it isn't true. The guy who re-posted it confessed already, Quote:
I don't even have e-mail notifications. I keep BAUT out of my e-mails since I have enough spam to want to suplement it with e-mail notifications from BAUT. I hope it clarifies the misunderstanding. But while I'm writing to you I'd like to learn what is your opinion on conservation of energy. There are at least two possible points of view: (i), which I call Feynman's, since it is in his texts from which I learned physics, that energy (defined as a component of 4-momentum) and momentum (defined as the rest of 4-momentum) are conserved separately, and (ii), which I call Baez's (your friend who tried to explain it to me a few times but poor me didn't understand a bit), that only the whole 4-momentum is conserved and that Feynman's idea applies only to Newtonian physics. Which means, according to Baez, that in relativity energy (as defined before) and momentum (as defined before) are not separately conserved. Which one is true in your opinion? I hope that you see that both can't be true simultaneously. Last edited by JimJast : 09-May-2008 at 12:42 PM. |

Actually I had one sensible question and I'm still working on the response since I still don't know how to solve analytically a seemingly simple diff. equ. (y"=y(sin(x)/x)^2) that the question leads to. But once it is solved some questions that I've never though of before might be answered and my already high confience in Einstein's universe might double So I don't complain. Actually, I'm happy that I got to this forum and I was presented with this question. The answer might be the sixth reason why Einstein's universe is better explanation of observations than the Bi Bang.Last edited by JimJast : 09-May-2008 at 04:49 PM. |

Since I don't understand the mainsteam point of view (I don't understand the mechanism of converting the momentum into the energy) I am doomed to asking this until I find someone who understands the problem and explains it to me. Of course, as Landau once said, "those who don't understand the problem might have problems with explaining it". And I can't blame anyone for not understanding how momentum is converted into energy while I don't understand it myself. I just know that it is the mainstream opinion and Jonh Baez believes it is possible, he just doesn't want to bother with the explanation ("too repetitive" he told me when he baned me from sci.physics.reseach forum for asking such questions long time ago). I hope that in this forum someone will be able to explain this problem of conversion of momentum into energy, depite that it is contrary to Feynman's opinion, documented by his texts, where he states explicitly that energy and momentum are conserved separately (and I don't think anyone can accuse Feynman of not understanding physics as good as John Baez). Why the astronomers subscribe to the non conservation of energy and agree only on conservation of the whole 4-momentum (i.e. whatever is missed in non conserved energy is taken from necessarily non conserved momentum since there is nothing else to make for conservation of 4-momentum)? That's why I keep asking the mainstream theorists what is the mechanism of this conversion that apparently Feynman missed. |

John Jones, what? Are you curious about the error message? I don't get the vague context.
If I guess right: There is a minimum size for an article. It's probably one character, but I'm not sure. The forum software doesn't count quoted material nor signatures, just actual characters you have supplied. If there's not enough (again, probably less than 1) characters, you must increase what you provided. === JimJast, You're not dialoging with Chris Hillman, according to his last message of 2008, April 16th (I believe it was): Quote:

Too bad...

I don't continue the discussion of "Einstein's universe" but I respond to posts asking me questions related to the conservation of energy. Should I appeal to the mods every time someone asks me something whether I may reaspond? It seems ackward.

Note that the board software doesn't include quoted material in the length count, so if you just quote something in your post without saying anything else about it, that will trigger this message.

I admit it was wrong because it messes the forum and irony of the situation is that I came to About BAUT to propose a way to improve the organisation of forum by making it "more to the point" but got diverted. |

I don't understand why you would want posts emailed to you. I have the default and get a link to the forum and I read it their. Saves a bit of bandwidth and avoids this issue. Why even allow posts to be emailed?
Just my two cents. Okay, make it a dime, with the devalued dollar and all.
