I want to start with spacetime J = spacetime derivative F and expand to

$e_{o}\rho +{\mathbf {J}}=(-e_{o}\partial _{0}+{\boldsymbol {\nabla }})({\mathbf {E}}e_{0}-I{\mathbf {B}})$

$=-\partial _{o}{\mathbf {E}}+I_{4}\partial _{0}{\mathbf {B}}+e_{o}{\boldsymbol {\nabla }}{\mathbf {E}}-I{\boldsymbol {\nabla }}{\mathbf {B}}$

Then decompose into dot and cross and equate parts to give the usual Maxwell equations. Selfstudier (talk) 11:51, 8 November 2010 (UTC)

Decomposition

$e_{o}\rho +{\mathbf {J}}=-\partial _{0}{\mathbf {E}}+I_{4}\partial _{0}{\mathbf {B}}+e_{0}\nabla \cdot {\mathbf {E}}+I_{4}\nabla \times {\mathbf {E}}-I\nabla \cdot {\mathbf {B}}+\nabla \times {\mathbf {B}}$ whence equating parts (timelike vectors e0, spacelike vectors ek, timelike trivectors I4e0 and spacelike trivectors I4ek) results in

$\nabla \cdot {\mathbf {E}}=\rho$

$\nabla \times {\mathbf {B}}-\partial _{t}{\mathbf {E}}={\mathbf {J}}$

$\nabla \cdot {\mathbf {B}}=0$

$\nabla \times {\mathbf {E}}+\partial _{t}{\mathbf {B}}=0$Selfstudier (talk) 14:15, 8 November 2010 (UTC)

The 3D decomposition can be done similarly but much more simply using just e1e2e3Selfstudier (talk) 14:56, 8 November 2010 (UTC)

If we start from $\left({\frac {1}{c}}\partial _{t}+{\boldsymbol {\nabla }}\right)F=c\mu _{o}J,$ we can expand to

$({\dfrac {1}{c}}\partial _{t}+e_{1}\partial _{x}+e_{2}\partial _{y}+e_{3}\partial _{z})[E_{x}e_{1}+E_{y}e_{2}+E_{z}e_{3}+c(B_{x}e_{2}e_{3}+B_{y}e_{3}e_{1}+B_{z}e_{1}e_{2})]={\dfrac {\rho }{\epsilon _{o}}}-c\mu _{o}(J_{x}e_{1}+J_{y}e_{2}+J_{z}e_{3})$

Then equate scalar,vector,bivector and i trivector terms for the usual equations.

• Aside*

Coordinate frame $e_{\mu }=\partial _{x^{\mu }}x$ reciprocal frame $e^{\mu }$ and define vector derivative $\nabla =e^{\mu }\partial _{x^{\mu }}=e^{\mu }\partial _{\mu }$

Maxwell tensor $\partial _{\mu }F^{uv}=J^{v},\ \partial _{[}\alpha F_{\mu v}]=0$

Spacetime equivalents are $\nabla \cdot F=J,\ \nabla \wedge F=0$ but we can combine with geometric product $\nabla F=J$Selfstudier (talk) 13:45, 8 November 2010 (UTC)

ME IsPal

Will keep notes here re this, situation has changed quite a bit in recent years but due to compete editing and other such nonsense its virtually impossible to get a page changed except other than superficially. Result is many errors and out of date and not up to date things in the relevant pages.

Example: see perfectly simple and straightforward name change put forward by self at Palestinian territories (to Occupied Palestine territory, which is what it is called by all of the high level people including the SecGen and Sec Council) Of couse, certain interests don't like plausible conclusions that might follow from this and so put up bureaucratic resistance that I can't be bothered to deal with.

Major errors have crept in because of a failure to address consequences of recognition of State of Palestine and of UNSC 2334

UNGA 20 Jan 2016 SecGen report A/HRC/31/43 Israeli settlements in the Occupied Palestinian Territory, including East Jerusalem, and in the Occupied Syrian Golan again, the use of Territory not territories, also in many other similar high level documents but because the WP bureaucrats say that there are thousands of low level documents using territories then those count ahead, lol.

Above doc : Legal background 4. An analysis of the applicable legal framework and the basis for the obligations of Israel in the Occupied Palestinian Territory and occupied Syrian Golan can be found in previous reports of the Secretary-General (see A/69/348, paras. 4-5, and A/HRC/25/38, paras. 4-5).

and if you follow the trail again you find Territory not territories.

So it is perfectly clear what the legal intent is regardless of any customary or administrative usage might be.

This message contains important information about an administrative situation on Wikipedia. It does not imply any misconduct regarding your own contributions to date.

Please carefully read this information:

The Arbitration Committee has authorised discretionary sanctions to be used for pages regarding the Arab–Israeli conflict, a topic which you have edited. The Committee's decision is here.

Discretionary sanctions is a system of conduct regulation designed to minimize disruption to controversial topics. This means uninvolved administrators can impose sanctions for edits relating to the topic that do not adhere to the purpose of Wikipedia, our standards of behavior, or relevant policies. Administrators may impose sanctions such as editing restrictions, bans, or blocks. This message is to notify you that sanctions are authorised for the topic you are editing. Before continuing to edit this topic, please familiarise yourself with the discretionary sanctions system. Don't hesitate to contact me or another editor if you have any questions.

Please read the above carefully and modify your behavior accordingly. No More Mr Nice Guy (talk) 20:19, 10 June 2017 (UTC)

Hello, Selfstudier. You have new messages at No More Mr Nice Guy's talk page.
You can remove this notice at any time by removing the {{Talkback}} or {{Tb}} template.

Hi Selfstudier: Some unsolicited advice. As the length of a talk page discussion increases, the probability of bad-faith accusations and incivility reaches one. If you find yourself at an impasse, stop trying to convince the other person of your position, and seek WP:DR. It's better for all involved.

Balfour Declaration

Hi Selfstudier,

according to the guc tool I have 1501 edits in English Wikipedia. I don't want mess up with you, but I would like to know whether this low quality map should be included?

IMHO it is not adding any value to the article and may disappoint the reader due to poor distinguishability. The content is well understandable without this illustration.

Best regards, --Kopiersperre (talk) 12:48, 27 June 2017 (UTC)

Sorry, I went by your history page, guess that gave me wrong info :) I have voted keep this image at Wikimedia Commons, will try to get a better one. As I stated at Wikimedia, it is in some respects more important to know that the image exists and that the FO prepared it than to be able to see all the details (in fact all you really need to know is that Palestine was included within the outline area). There was a link to a source with a high res image that you also deleted when you made your edit, tho that's only good if you happen to possess the source Selfstudier (talk) 13:08, 27 June 2017 (UTC)

Please let's continue the discussion where it started. I would be very glad, if we will get a high quality version in the end. But before we've achied this goal I'm against an inclusion of the map in the article.--Kopiersperre (talk) 13:23, 27 June 2017 (UTC)

That's a different problem (that has been addressed at least twice bfore that I know of, perhaps more, lol). Your edit has been reverted so since it is an IsPal page, you are required to obtain consensus for that on the relevant talk page (there are three different articles that have it, I think, all related to each other). At this point, just saying that the image is low res and therefore useless is not going to win the day, I'm afraid.Selfstudier (talk) 13:39, 27 June 2017 (UTC)

Copying licensed material requires proper attribution

Hi. I see in a recent addition to Sykes–Picot Agreement you included material from a webpage that is available under an Open Government Licence. That's okay, but you have to give attribution so that our readers are made aware that you copied the prose rather than wrote it yourself. I've added the attribution for this particular instance.

Balfour Declaration

Hi Selfstudier

I would like to comment that any encyclopedic depiction of the Balfour Declaration, which does not refer even in a word to the Faisal-Weizmann Agreement, would be partial and lacking, if not misleading.

A considerable portion of the Entry is devoted to “Reaction” to the Declaration, including a paragraph on “Broader Arab response”, with specific reference to the Sharif of Mecca (the father of king Faisal). Overlooking the true reaction of the Sharif, which was at least partially demonstrated in the Faisal-Weizmann Agreement, might well be considered as a bias.

The Faisal-Weizmann Agreement Main article: Faisal-Weizmann Agreement The Sykes–Picot Agreement divided vast territories under then-Ottoman rule, into future British- and French-administered areas, and allowed for the internationalisation of Palestine. In the aftermath of the agreement, Emir Faisal I, the son of Hussein ibn Ali al-Hashimi, Sharif of Mecca and King of Hejaz, attempted to secure international support for his rule over Damascus and Greater Syria, and for that end sought collaboration with the Zionist Movement. The Faisal-Weizmann Agreement, signed on the fringe of the Paris Peace Conference, on 3 January 1919, by Emir Faisal and Chaim Weizmann, was directed to establishing Arab–Jewish cooperation on the development of a Jewish homeland in Palestine, and an Arab nation in a large part of the Middle East. Following the Balfour Declaration, Article IV of the agreement stated that

All necessary measures shall be taken to encourage and stimulate immigration of Jews into Palestine on a large scale, and as quickly as possible to settle Jewish immigrants upon the land through closer settlement and intensive cultivation of the soil… — Preceding unsigned comment added by 77.126.23.51 (talk) 08:02, 17 July 2017 (UTC)

I am not sure why you are messaging me directly rather than putting a commentary on the Balfour talk page where other editors might also comment on your thought. I have not as yet had time to fully look into the matter of this agreement, still there are a couple of things that are worth mentioning:

1)The codicil to this agreement refers to the Arab claim at the Peace Conference which I understand included the area called Palestine (the Arabs were understood to have little difficulty with a Jewish presence under an Arab suzerain instead of a Turkish one). 2)The agreement was a fiction from the outset, the British (Balfour) had suggested the obtaining of it when they already well knew that Arab demands were not going to be met. 3)It is certainly worthy of some investigation that the Agreement is in English only and the codicil the only thing in English and Arabic (and on a separate sheet of paper) with Lawrence acting as translator. 4)I would say that whatever this Agreement meant was not so much a reaction to the Balfour Declaration (the Arab reaction in Palestine to it was already by 1919 very clear and they were not even consulted) as a reaction to the pressures of the Peace Conference and international diplomacy, a desire to be seen as a help and not a hindrance to the process.

I will pay some attention to this a bit later on, that's my 2 cents meanwhile :)Selfstudier (talk) 09:13, 17 July 2017 (UTC)

Tx. Not sure how to technically comment properly. Anyhow some further detailing follows. The Sharif of Mecca, Hussein ibn Ali al-Hashimi, was a key figure in the British diplomacy in the Middle East and the addressee of the McMahon–Hussein correspondence. His importance and relevance to the Balfour Declaration is reflected from the reference to him in the preface to the Entry, as well as from numerous references further below. The paragraph under “Broader Arab response” practically focuses only on the negotiations between him and the British following the publication of the Declaration.

The overall impression to the reader from these citations is that the Sharif totally objected to the Declaration. However, the Agreement between his son and Weizmann in 1919 shows that this was not the case, as the Agreement endorsed massive Jewish immigration to Palestine. The codicil to the Agreement only shows that such endorsement was subject to the Sharif’s assumption and hope that – in return to his welcoming the Jews – the British will guarantee his own family ruling over Palestine.

The bottom line is that the Faisal–Weizmann Agreement is no less relevant to the Entry than the McMahon–Hussein correspondence, and its exclusion of it is unjustified. — Preceding unsigned comment added by 77.126.23.51 (talk) 15:25, 17 July 2017 (UTC)

I finally got around to fixing up the FWA page and have put something in the BD article about it; if you read the WZA article now, I am sure will see why it is often called the "forgotten agreement", an inconsequential episode, nothing more than that.Selfstudier (talk) 13:25, 25 July 2017 (UTC)

Thanks for all the great work you have been doing here and at associated articles.

As I mentioned in the past, I am hoping to get the article past a Wikipedia:Featured article review, and then subsequently a Wikipedia:Today's featured article/requests. These are quite weighty processes, and I have not been through it before. Fortunately, FunkMonk has been mentoring me through each of the steps.

I am posting here to ask if you would like to support me in the nominations - I can nominate in both our names.

GASpin

In ${\mathcal {G}}(2,0)$, even multivectors are of form $x+Iy$ and odd multivectors are ordinary vectors. Noting that the pseudoscalar squares to $-1$, the even multivectors have the form of a complex number. Multiplication of a vector on the right by a complex number (in the sense of an Argand diagram), rotates and scales it.

This idea can be generalised and taken to higher dimensions using the rotations terminology already introduced to rotate a vector $v$ with a spinor $\psi$

$v(x+Iy)=vre^{I\theta }=(r^{1/2}e^{-I\theta /2})v(r^{1/2}e^{I\theta /2})=\psi v\psi ^{\dagger }$

The above identifies spinors with the even subalgebra (a subalgebra under the geometric product), in other words spinors are general combinations of the even elements of ${\mathcal {G}}(p,q)$, (Not dubious since no such claim has been made) yields the GA definition, a multivector $\psi$ in ${\mathcal {G}}(p,q)$ such that $\psi v\psi ^{\dagger }$ is in ${\mathcal {V}}(p,q)$ for all $v\in {\mathcal {V}}(p,q)$.{{sfn|Bromborsky|2014|p=28}

In physics, early encounters come as Pauli spinors, a column "vector" with 2 complex components acted on by Pauli matrices and later with 4 complex components and acted on by Dirac gamma matrices (relativistic quantum spin of spin 1/2 particles). An introductory GA treatment of how these formalisms translate in GA is given by Doran and Lasenby {{sfn|Dorst|Lasenby|2003|p=268-276}A GA derivation of the Lorentz transformation making use of this formalism is shown by Bromborsky.{{sfn|Bromborsky|2014|p=28-30}

This is a standard message to notify contributors about an administrative ruling in effect. It does not imply that there are any issues with your contributions to date.

You have recently shown interest in the Arab–Israeli conflict. Due to past disruption in this topic area, a more stringent set of rules called discretionary sanctions is in effect: any administrator may impose sanctions on editors who do not strictly follow Wikipedia's policies, or any page-specific restrictions, when making edits related to the topic.

For additional information, please see the guidance on discretionary sanctions and the Arbitration Committee's decision here. If you have any questions, or any doubts regarding what edits are appropriate, you are welcome to discuss them with me or any other editor.

@Icewhiz: As I explained in the article talk page, your edit was a global undo of multiple edits made between 6 and 8 October with an explanation given "Not an improvement" applied to all, even though the edits were unrelated and included source reference additions and further without responding to the various comments relating to these edits that had been made on the article talk page. This seems to be unreasonable and is why I reverted the global edit with a request that the individual edits be addressed one by one rather than all at once.
