The method of used for numbering the references here is regrettable. If references are numbered by hand rather than by the software, and someone wants to add another one between 8 and 9, then all of the listed references after number 8 need to get renumbered by hand, and the places where they are cited in the article need to get changed! We have software that takes care of that. But it wasn't used here. Michael Hardy (talk) 04:23, 31 March 2012 (UTC)

Hi! I can see you are interested in expanding this article. I'm a fan of geometric algebra and geometric calculus myself, so I really look forward to your contributions.

I'm not positive which things exactly you have added, so the following may not be applicable to you. Judging from how recently your contributions have begun, it might be that nobody has mentioned these things to you. One thing to remember is that Wikipedia requires articles to maintain a neutral point of view, and so I had to remove some subjective statements from the article. There are still a few statements that are fine to include (but need substantiation), and I hope you can help by providing citations for them. There were also a few points in the article where it strayed offtopic, becoming more about the books and fields of study rather than the person. For more information on the neutral point of view policy, check out this. Rschwieb (talk) 19:28, 11 April 2012 (UTC)


 * Hello, apologies if this sounds patronizing and confronting...but you need to understand...


 * It would be far easier for everyone, including yourself: to cite a source at some point in the text - just click the reference button on the edit panel (it looks like a book) and type the source in the box which shows up. Or even just type  .


 * That way - the referances are autonumbered, and you do not have to tediously edit the numbers by hand and we do not have to waste time clearing up the mess afterwards (in any case check if there is a  typed exactly like that, including curley brackets).


 * Furthermore you've done it wrong : your numbering is not consistent (there is no [1] or [19] in the article text, but there is in the list...) so its on you to correct that and match the sources properly - else the edits will be reverted by someone since the facts will not be verifiable... I tried to fix up the citations my self, but can't since I don't know where [1] or [19] are exactly supposed to be (accidental numbering error on your part...)..


 * This is important, so please do this - for everyone's sake including and especially your own. Thank you. If you're still unsure on how to reference by all means see: Citing sources and Verifiability. F = q(E+v×B) ⇄ ∑ici 20:44, 11 April 2012 (UTC)


 * It has been sorted out by someone else. In future, please do this - thank you. Again, apologies for rigid words. F = q(E+v×B) ⇄ ∑ici 15:46, 14 April 2012 (UTC)

XOTAR reference in article on David Hestenes
I have had to temporarily remove some content you had added to the article on David Hestenes. Please look at my edit comment here. The statement that the Hestenes is a co-founder of XOTAR corporation requires a reliable source, please see WP:RS on what counts as reliable source in Wikipedia. --Chris Howard (talk) 22:08, 14 April 2012 (UTC) P.S.: I could not either so far find a page on XOTAR's web site that would indicate names of co-founders and/or the year in which XOTAR was founded. There is a page on LinkedIn indicating XOTAR was founded in 2009/2010, but if the information that Hestenes or others are co-founders of a company is to be considered of relevance to an encyclopaedia, the full information should at least be specified clearly on that company's own site. In case you indicate which page contains the information, I could add it for you to the article on David Hestenes, as reference. Do let me know; I will "watch" your talk page, so you can simply add it here if you wish. --Chris Howard (talk) 13:22, 15 April 2012 (UTC)
 * Chris - I am the founder of XOTAR Corp., and indeed David Hestenes is a co-founder. The information is not on the website yet since other people are going to be announced at the same time. Sometime in the next week the information will be posted on XOTAR's site and i will signal you accordingly. Thanks for fixing all of the references BTW, I was intending to fix all of them after learning how to do it properly in the first reference. I am dismayed that the other person q(E+v×B) removed the diagram from the page which was higly informative about the historical roots of the subject that was the origin of the work that David focused on during his career. — Preceding unsigned comment was added by User:Xtr rossi (talk) 15 April 2012

Xtr rossi, this is all the more reason to not put it on Wikipedia yet until such information is fully official. About the graphics, I think that the picture was moved because it was not evident from the graphics itself, nor from any figure caption, that it was from Hestenes himself. However, I vaguely remember that I saw the figure in one of Hestenes' own publications, as a work he did himself. Could you give a reference? Preferably a peer-reviewed journal article or book. With such reference, there could be good reason to re-insert it into the article, not in giant format, of course. Don't worry about the references fixes BTW, I earned a nice banner on my talk page for it :-) One more point: if you have reliable references – by Chris J.L. Doran, Pertti Lounesto, or others – who put Hestenes' work in perspective, that would be helpful. Then possibly the article could be rid of the remaining problem-banner. --Chris Howard (talk) 22:30, 15 April 2012 (UTC)
 * As mentioned on the talk page, the picture is not appropriate for the page. You say it is informative about the history of "the subject", meaning GA and GC. This is not a page on the history of GA and GC, it is a page on David Hestenes. I did move the graphic to the GC page, because it works well there. Rschwieb (talk) 01:00, 16 April 2012 (UTC)


 * Ok Xtr rossi - where did you find out that I moved the picture? I didn't and you only need to check the edit history to find out these things. Here they are for David Hestenes, Geometric algebra, and Geometric calculus. For one thing - the diagram was good and certainly appreciated, but the move was appropriate anyway for reasons Rschwieb just mentioned. F = q(E+v×B) ⇄ ∑ici 05:46, 16 April 2012 (UTC)


 * Wikipedia life can be difficult, especially for newcomers who still need to learn about the history tab on the top of an article, or how to sign their edits (Xtr rossi: this is ideally done by pressing on the signature+pen icon at the top of the editing window, leading to two dashes and four tildes --~ to be inserted, which are then automatically translated to the user's signature and time when performing "save"). Let´s take it step by step.
 * Concerning the diagram, I too have given it further thought and came to the conclusion that it would be best to display it on both the GA and the GC page, but definitely I would want the figure caption to be improved, e.g. "according to [ref.] ". That way, readers who want to learn about Hestenes would find it when looking at either one of the central articles GA and/or GC. While I personally would not in principle object against graphics like this being in the mathematician's article in case the graphics was indeed first published by him (after all, the "unification" as represented in the graphics is very central to all of Hestenes' work), I do think it would mean overdoing it if users were confronted with the same graphics in all three places. In case we all agree, fine; if not, a good place to discuss it could be Talk:Geometric_algebra. --Chris Howard (talk) 16:19, 16 April 2012 (UTC)
