<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I'm not sure why you are so stuck on the induction equation.&nbsp; It would seem the induction equation is used as a starting point.&nbsp; What is important is how the equation is solved and which terms are dominate.&nbsp; How you solve the equation tells you what direction you can proceed further.&nbsp; You see this same process with the Einstein Field Equations.&nbsp; There's more than one solution and more than one direction you can proceed.Maybe you could enlighten me to what the importance is and why you feel that using this equation doesn't allow for magnetic reconnection.&nbsp; <br /> Posted by derekmcd</DIV></p><p>It demonstrates that the motive force behind the acceleration process is simple induction, not "magnetic reconnection".&nbsp;&nbsp; The induction process kicks in as the topology of the "circuits" change during the reconnection process.&nbsp; </p><p>Rather than whip this dead horse on this forum any further, I am actually going to put together a real paper on this topic and I will submit it to either the APJ or the Science Magazine.&nbsp; I have no illusions about them actually publishing it, but at least I will have gotten all this off my chest.&nbsp; You're welcome to add your two cents and join me if you like. :) </p><p>IMO, It's critically important that all branches of science speak the same language when it comes to specific use of scientific terms, expecially terms that are directly related to Maxwell's equations and to MHD theory.&nbsp; An electrical engineer (and Alfven qualifies as such) would look at Priests diagrams and his mathematical equations and describe them in terms of "circuits" and "induction". &nbsp; That is how Alfven explained them in MHD theory as well.&nbsp; If astronomers intend to start using their own unique "lingo" to describe what amounts to "circuit reconnection" and "induction", it makes communication between the various fields of sciences very difficult.&nbsp; Magnetic field lines never "reconnect", only "circuits" reconnect according to Maxwell's equations and all electrical engineering principles.&nbsp; Induction is a likely outcome of a topology change in the circuits, and these are used in the definition of magnetic reconnection.&nbsp; To call this whole process of circuit reconnection and induction "magnetic reconnection" is to necessarily confuse "cicuit reconnection" and "induction" as defined in electrical theory with "magnetic reconnection" theory in astronomy.&nbsp; Communication then between electrical engineering, MHD theory and astronomers becomes unnecessarily tedious and frustring as a result.&nbsp; The very term itself is highly misleading because everyone here agrees that magnetic lines don't ever actually reconnect, so it's not actually a "magnetic reconnection" process even according to you folks.&nbsp; We can see that in the equations that were selected by Priest to describe this theory. They are based on circuit reconnection and induction.&nbsp; It would have been scientifically correct to label this "circuit" reconnection, but it is scientifically incorrect to describe this process as "magnetic" reconnection.&nbsp; Magnetic field lines are not reconnecting, just circuits.&nbsp; Induction is just the outcome of the circuit reconnection process. </p><p>Like I said, rather than go through this process on Space.com for another couple of weeks, I rather just write a paper.&nbsp; If you're really interested in reading it, email me and I'll send you a copy when I'm finished.&nbsp; I started on the paper yesterday and I probably have a couple more days of writing before I'm ready to send it to anyone.&nbsp; I will use the diagrams and equations used in Priest's paper to make my point along with everything else I've learned in this discussion.&nbsp; I will also include Alfven's comments on this topic and show how they are consistent with electrical engineering principles, MHD theory, and Maxwell's basic equations, whereas the term "magnetic reconnection" is not compatible with any of them. </p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>No, I intend to explain "magnetic reconnection" theory as outlined by Priest and then compare it to an ordinary circuit explaination from the perspective electrical engineering.&nbsp; I will then show Alfven's MHD explanations were based on circuit reconnection theories and then explain why it's critically important to do that based on Maxwell's equations. If you guys can convince Yevaud that ok, I will post a link to the paper when it';s done and I will invite criticisms to my paper on this thread.&nbsp; I don't want to do that however is Yevaud and the other moderators are not in agreement, and I'll be happy to email you a link and you can critique it by emial if you like.&nbsp; I am highly interested in your feedback and I would like to 'clean it up" before I submit it. &nbsp; I'd like them to at least consider publishing it and I'm not taking any uncessary "shots" at the mainstream in the presentation.&nbsp; It's just a simple presentation about the need for the consistent use of terms accross all fields of acience, including electrical engineer, MHD theoy and astronomy.&nbsp; &nbsp;&nbsp; FYI It is precisely because I have no objections to Preists mathematical models or his diagrams that allows me to focus on the importance of consistency of suse of scientific terms.&nbsp; I have no need to pick apart his math.&nbsp; I just need to show how it relates to ordinary "circuit" reconnection and induction.&nbsp; I will be fair in my presentation and I intend to show that "magnetic reconnection" is an improper use of scientific terms and it would be more appropriate to label this process "circuit reconnection" as Alfven did. <br />Posted by michaelmozina</DIV></p><p>&nbsp;I don't see how anyone could object to your posting a link to a draft of a paper that is to be submitted for publication.&nbsp; I would love to see it.<br /></p> <div class="Discussion_UserSignature"> </div>

<p>Thus far eveything I've written relates to Priest's work, his diagrams, his mathematical models and his use of terms and how that compares and contrasts to the use of term in electrical theory and Alfven's views on plasma physics.&nbsp;</p><p> I'm debating on whether or not I should even mention the PPPL experiment and wheither I should mention the criticisms I have specfied of that experiment because it is the only true "experiment" done on this topic and it reports to support the idea of magnetic reconnection.&nbsp; I am concerned that adding this issue to the paper will only distract from the primary argument about the consistent use of terms in science, but I am equally concerned that if I do not include any mention of this experiment that the paper will be seen as incomplete.&nbsp; Suggestions?</p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>
