<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Once again, the problem here is you are arguing something entirely different than the rest of the people in this thread. IF we were asserting that something is LITERALLY reconnecting, as in disconnecting physically and then being spliced back together, then yes, you are right, magnetic fields can't do that.</DIV></p><p>Then it should be called by it's proper name, "circuit and particle reconnection". We all know that magnetic fields form a complete and full continuum, without beginning and without end. They don't "reconnect", "disconnect", get spliced, or do a break dance. There is no form of "magnetic reconnection" occuring in these events. These are simple circuit reconnection events that may involve a bit of induction. That's it. There is nothing unique about "magnetic reconnection" at the level of particle physics and electrical engineering. It's simply a circuit and particle reconnection process. Why call it ""magnetic reconnection" when magnetic fields never "reconnect" and the reconnection process is a "circuit reconnection" process based on Maxwell's equations and the laws that govern these equations?</p><p>That was really the purpose and point of my paper in nutshell. By mislabeling the particle physics process of particle and circuit reconnection, astronomers have essentially created their own unique and highly confusing "lingo" to describe what is simply "circuit reconnection" and/or "inducition" in plasma. By creating their own lingo, they create a skism between MHD theory and electrical engineering at one end, and astronomers at the other end. The term itself, "magnetic reconnection", is highly inconsistent with Maxwell's equations and MHD theory because magnetic fields do not "disconnect" or "reconnect", only particles and circuits can "reconnect".</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The theory of magnetic reconnection DOES NOT SAY THIS and NEVER DID. </DIV></p><p>The very term itself *implies magnetic disconnection and magnetic field reconnection* in a highly explicit manner. What's the point of calling it "magnetic reconnection" then in the first place if you arent' trying to confuse the heck out of everyone who's studied electrical engineerining or MHD theory as Alfven desribed it?</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>You are trying to disprove a theory of reconnection that simply does. not. exist. </DIV></p><p>Thus far I haven't actually read a mathematical theory of "magnetic reconnection" that is actually based on physics and Maxwell's equations. Thus far all I've seen are presentation that are based on pure math and mythical particles.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The reason Priest's paper got accepted is because he backed up his claims.</DIV></p><p>How exactly did he back of his use of "monopoles" in Maxwell's equations? Didn't Guth solve the "missing monopole" problem with inflation? Now you're telling me that monopoles are everywhere inside of plasma events and everywhere inside of our own solar system? Care to explain how Priest demonstrated monopoles or how he even justifies using that term in association with Maxwell's equations? Don't they violate the laws (as we know them today) of these very same equations, namely Gauss's law of magnetism? </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> You don't see what gets exchanged between author and referee. I am quite sure that the referee would've at least asked why this introduction of monopoles was necessary, if he didn't already understand it in the first place, and Priest obviously gave a reasonable explanation. </DIV></p><p>So let's hear it? I certainly never saw any sort of explanation in his actual paper.</p><p>Wasn't the point of Priest's paper to demonstrate that "magnetic reconnection" could be explicitly derived from Maxwell's equations? Weren't we trying to explain the mathematical derivation and justification of "magnetic reconnection" theory? Which of Maxwell's equations uses or describes "monopoles"?</p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Often times people make simplifying assumptions that they know aren't necessarily true because it has no effect on the end result. </DIV></p><p>Um, in this case, this particular equation is where all the "magic" seems to occur in "magnetic reconnection". The one thing that seems to make that magic possible is his use of "monopoles". I'm afraid magic is not phyiscs and monopoles do not exist in nature. That is why the laws of physics treat all magnetic fields as dipole fields and not as monopoles. I therefore can't convert monopoles into EM equations.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Hence the name, "simplifying assumption". </DIV></p><p>I can't simplify Maxwell's equations with my invisible friend Carl or monopoles. That's not just a "simplifying assumption", it's one that defies the laws of physics as we know them.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Magnetic monopoles may or may not exist, we do not know that for certain yet. </DIV></p><p>We are certain that all interactions with magnetic fields follow a dipole pattern of interaction in every controlled test of electrical theory that has ever been done to this date in history. There's no point in making stuff up and calling it "physics". Monopoles are not "physics", they are *hyothetical* entities that violate all the known laws of physics. If and when that ever changes based on emprical experimentation, *then* you can call it "physics".</p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>You say that the existence of monopoles isn't predicted by Maxwell's equations...well, neither was displacement current until it was discovered, following which they modified the equations.</DIV></p><p>That's correct. However, Maxwell's changes to Ampere's equations could be demonstrated in a lab under highly controlled conditions and repreated in controlled experiments. When was that ever done for "monopoles"?</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>If I could think of a reasonable way to ask an un-loaded question to Birn about his paper, I would. I can't just ask him to sit down and walk me through the paper because his job is not to teach.</DIV></p><p>I'm definitely not asking you (or him) to get that deep into the conversation or the paper. You might just mention to him that someone you know is interested in attempting to convert the equations in his paper to an electrical point of view and this individual was curious if DrRocket's general descriptions of the field relationships made sense to him. It looks to me like DrRocket's description of the relationships between the various fields and vectors accurately describes the important relationships in question. I believe that DrRocket is correctly representing these relationships but I'd like to be sure that the author agrees before I get carried away again. I've been down that road once already this week only to hit a dead end at monopole lane.
I don't feel like spinning my wheels again on something that isn't quite right. I do trust DrRocket, and I generally agree with his explanation of the basic relationships, but it would be nice if Birn or Hesse or Schindler agreed before I got too carried away. My vector calculus days were many years ago. While I liked these mathematical challenges way back in college, I'm a bit rusty these days and I will defintely have to really work at this process for some time to get it right. I just want to be sure I'm not barking up the wrong tree from the very start.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>And even if he did he wouldn't tell me anything I couldn't learn by reading the paper and its references with a physics textbook for help. If you can't get over the monopole thing, jsut email Priest and ask him why it was necessary. You may find that the answer is already there. <br /> Posted by UFmbutler</DIV></p><p>The "answer" seems to be there in the equations themselves. Priest evoked something that does not exist in nature to attempt to simplify and represent a physical process of nature. That's not physics anymore. There are no monopoles in nature anymore than there are invisble Carls in nature. Emprical science is precise and requires the use of emprical physical items, not mythical particles and invisible friends. I can't convert monopoles or invisible Carl to E or j and still rationalize it as "physics". His "explanation" of his evocation of monopoles would necessarily "taint" my presentation, no matter how I try to rationalize or justify his use of the term "monopole" in his paper. There is no point in worrying about *why* he did this, or why he made this mistake, the fact he did it makes me (by proxy) look silly IMO. I can't convert his monopoles to physics no matter how I try to rationalize it or justify it. Hopelfully Hesse and Birn and crew offer us a better opportunity, albeit a harder one, to show the relationship between "magnetic reconnection' and "circuit reconnection" when looked at from the persective of electrical engineering. </p><p> That's really all I'm really looking for in the final analysis. Any "well" (not stepping outside of physics) written paper on the topic of magnetic reconnection theory that is based on Maxwell's equations (and only Maxwell's equations) should be convertable to E and/or j. That may require math skills far beyond my abilities depending on the presentation in question, but I'm certain that it's doable by someone with enough mathematical skill. </p><p>For my paper to be published in a mainstream publication, itt will and must necessarily show that any agreed upon form of "magnetic reconnection" is simply a mislabeling of "circuit reconnection' and "particle reconnection" and maybe a bit of induction as well. What I was hoping to do is show that mathematical relationship and explain why it's very important that all branches of science stay on the same page as it relates to use of scientific terms. </p><p>From what you and DrRocket have discussed thus far, I'd say that my skill set at math would be pushed to it's absolute limit to convert Birn's mathematical model to an electrical perspective. I'm just trying to make sure it's even a worthwhile endeavor before I think of giving it whirl. I'm not in any great hurry necessarily, and I"m willing to work at it for awhile and pull out some of my old calculus books off the shelf and do some reading too. I just want to be sure that the relationships that DrRocket describes make sense to at least one of the authors of the paper before I get too carried away. I also want to read the paper quite thuroughly before I begin my mathematical conversion to make sure their paper doesn't evoke something that I can't convert. *If* I can start with set of Maxwell based equations that describe "magnetic reconnection" and show how they represent what is ultimately a "circuit reconnection" process, *then* the rest of the arguments in my paper about the need to keep all branches of science on the same page is justified and there is at least a slim hope of it being published.. If I can't do that, then I'll have to rethink this whole strategy a bit. </p><p> My original "beef" was the Themis paper that attempted to support "magnetic reconnection" based on two failed models of "magnetic reconnection". From that point the conversation this discussion has "evolved" into a general discrorse on what magnetic reconnection might really be since we all seem to agree that magnetic lines don't "disconnect" or "reconnect". I'm certain that any Maxwellian presentation of "magnetic reconnection" can be shown to be nothing more than "circuit reconnection' and/or "particle reconnection" and/or "induction". These would be better "scientific terms" for this circuit reconnection process since that is what is ultimately "reconnecting", not the magnetic fields. If I can show this mathamatically, then a paper is justified. If I can't do that, then I doubt it would have a prayer's chance in hell of being published. I obviously can't convert Priest's monopoles to something else in Maxwell's equations because there is no conversion process between E, B, or j and monopoles that is described in Maxwell's equations. If Hesse and Birn and Schindler stuck to real physics, at least there is some hope of showing this mathematical relationship. That's ultimately what I'm looking for. You might mention to him that I am actually interested in finding a well written paper on this topic and that I'm more interested in showing the connection between "circuit reconnection" and "magnetic reconnection" than I am interested in debunking any more papers on this topic. I really would like to find a paper that clearly and susinctly describes magnetic reconnection in terms of Maxwell's equations. Whether I have the math skills to convert it is another question entirely, but without a "good" explanation of "magnetic reconnection", there's simply no hope that I can show the mathematical connection between circuit reconnection and magnetic reconnection. It's just as important to me as it is to them that their math is "right". I'll I'm trying to pick on is a specific use of terms that would apply to all papers on the topic of "magnetic reconnection". I need a well written mathematical presentation of magnetic reconnection as much as they do. </p> <div class="Discussion_UserSignature">
