potential

Hello, I read quickly your paper about how to derive gravitomagnetism, and while reading the part that talk about electromagnetism, I have been very astonished by the inclusion of a term related to the displacement current in electric potential. I also never saw the magnetic part written like that. It is only my fifth year of studies (and I am French, hence the bad English I am using), I just know about that http://en.wikipedia.org/wiki/Electromagnetic_potential, do you have other references that include the term you wrote? Have a good day.Klinfran (talk) 08:42, 13 May 2010 (UTC)

Hello Klinfran, I'm a bit busy right now preparing for an oral exam, but here's an answer for now. (Since I now know that someone is actually interested in this paper, I'll be sure to write an introduction to the paper after the exam!) I'm not sure exactly what you're referring to, but I assume you mean equations (6) and (7) in the paper. The general idea (and probably these exact equations themselves) can be found in David Griffiths' Introduction to Electrodynamics (http://www.amazon.com/dp/013805326X). Equation (6) is this:

$-\nabla ^{2}V-\partial _{t}\mathbf {\nabla } \cdot \mathbf {A} ={\frac {1}{\varepsilon _{0}}}\rho ^{\textrm {f}}-{\frac {1}{\varepsilon _{0}}}\mathbf {\nabla } \cdot \mathbf {P}$.

This equation can be obtained if you take the local, differential Gauss law of the Maxwell equations

$\mathbf {\nabla } \cdot \mathbf {E} ={\frac {1}{\varepsilon _{0}}}\rho$,

split the charge density $\rho$ into it's "free" and polarization/"bound" parts,

$\rho =\rho ^{\textrm {f}}-\mathbf {\nabla } \cdot \mathbf {P}$,

and substitute in the potentials expression for the electric field,

$\mathbf {E} =-\mathbf {\nabla } V-\partial _{t}\mathbf {A}$.

The same ideas apply for equation 7, where there is a "free" current, a magnetization current $\mathbf {\nabla } \times \mathbf {M}$, and a polarization or "displacement" current $\partial _{t}\mathbf {P}$. Zeroparallax (talk) 18:08, 13 May 2010 (UTC)

Ok thanks a lot, that was pretty simple, yes I was talking about that, good luck for your oral, and sorry for the late.Klinfran (talk) 20:48, 2 August 2010 (UTC)

Star article

Hello RJHall! Is this the best venue to discuss my edit that was removed? The note saying that "the lead is meant to be a summary of the article" implies that if I add my material to the body of the article as well, it should be okay in the lead/intro. Is that correct? Zeroparallax (talk) 00:33, 23 October 2010 (UTC)

Hello Zeroparallax. We can discuss it here or in the article talk page, as you prefer. In general, based upon interpretation of the policy in WP:LEAD, the lead is meant to be a high level summary of the important parts of the article. No offense, but your addition didn't really strike me as a critical addition; it just seemed an unsourced statement of the obvious. It could probably be added to the body without anybody objecting, but personally I'm a little dubious about the need to put it in the lead. Perhaps we need to hash this out further on the article talk page? Thank you.—RJH (talk) 00:01, 25 October 2010 (UTC)

Hello, and thank you for your contributions to Wikipedia. This is just a note to let you know that I've moved the draft that you were working on to Draft:You Were There (disambiguation), from its old location at User:Zeroparallax/You Were There (disambiguation). This has been done because the Draft namespace is the preferred location for Articles for Creation submissions. Please feel free to continue to work on it there. If you have any questions about this, you are welcome to ask me on my talk page. Thank you. Curb Safe Charmer (talk) 18:14, 10 March 2018 (UTC)

Draft:You Were There (Michael Jackson song) concern

Hi there, I'm HasteurBot. I just wanted to let you know that Draft:You Were There (Michael Jackson song), a page you created, has not been edited in 5 months. The Articles for Creation space is not an indefinite storage location for content that is not appropriate for articlespace.

If your submission is not edited soon, it could be nominated for deletion. If you would like to attempt to save it, you will need to improve it.

You may request Userfication of the content if it meets requirements.

If the deletion has already occured, instructions on how you may be able to retrieve it are available at WP:REFUND/G13.

Thank you for your attention. HasteurBot (talk) 01:25, 30 November 2019 (UTC)
