Hi MathsPoetry,


Good news! You now have access to 80 million articles in 6500 publications through HighBeam Research. Here's what you need to know:
First, I want to apologize for any rudeness on my part -- it's hard to modulate oneself in text communication. You requested input about the question of whether three lines in the article constitute original research; it seems to me that instead they constitute a necessary attempt to take notations from several sources and make them agree, together with a small amount of algebraic manipulation, and this is the point of my comments in the discussion you started. On the other hand, you have made some unrelated comments here and there about the general inaccessibility of this article, and pointed to the corresponding French article. I agree that the French article has some clearly desirable features, most notably some pretty pictures and concrete examples. I think that it would probably be very easy to improve the English article by translating and copying some of this material. In any case, I would hate to be responsible for chasing you away from editing math articles in English wikipedia, as you obviously are a skilled editor (even though we disagree about the original, fairly minor point).

== Templates on fr:WIkipedia ==
You've really not been that rude. Furthermore, if I look back at the various contributions, the harsh person has been me, not the others. Anyway, apologies accepted.


While translating [http://fr.wikipedia.org/wiki/Dimension_(th%C3%A9orie_des_graphes)] into English, I have found that fr.wikipedia.org uses templates "démonstration" and "Théorème". If en:Wikipedia has equivalent templates (which seem to me an excellent device) I have failed to find them. What would you advise? [[User:Maproom|Maproom]] ([[User talk:Maproom|talk]]) 19:04, 25 April 2013 (UTC)
With respect to the many edits, I guess it's because I am both disconfident of my mathematical assertions (I tend to verify everything ten times when I prove something), and of my level in English. That probably explains why your remark has hurt a bit.

== The Wikipedia Library Survey ==
If I am leaving the English wikipedia (or intended to leave it -- your apologies are putting me into deep confusion, I was not expecting them), not because of rudeness, but because of two things:
* first, I was really wanting to help with this article, I was ready to rewrite it from scratch based on the experience with the French one, and got the impression that this (implicit) proposal was met only with disdain
* second, I saw in very few hours all my world of wikipedian certitudes croll down :
** that we were writing for the general public, not for experts
** that we had to refrain from doing our own research
** that we had to source everything (and that it also meant that the source verification had to be straightforward)

You must realize I'm almost a newbie here, but I have 15 k edits (no, not hesitation edits, mostly real ones...) and I think people appreciate me usually. You can see my contributions in English, which are not many, on:
<!-- EdwardsBot 0678 -->
* [[Bayesian spam filtering]] (I did all the maths)
* [[Quaternions and spatial rotation]] (The proof named "quaternions in practice"), and
* [[Gimbal lock]] (especially the math explanations).
But all of these were my first wikipedian contributions, so I am quite ashamed now I see them.

Hi MathsPoetry,

it is a pity that the discussion about expanders became so personal. It is obvious to me that your contributions have improved the article a lot. Also, the disputed paragraph is questionable in many senses.

The reason I firmly disagreed with you (and I would guess this is the same reason why some other editors disagreed with you) is that I replied to a specific assertion you made, "A contributor has put a theorem of his own in an article". To me this sounded like an unfair accusation towards an editor who obviously acted in good faith: he took a formula from the BHT article and translated it to the notation in which our article is written (on the way, he made an error, also in good faith: on page 1 of BHT there is a remark that they denote ''twice'' the eigenvalue by ''&lambda;''<sub>2</sub>; this remark is easy to miss).

As I have a rich experience of communication failure in languages which are not my mother tongue, please do not take personally any of the comments in the discussion (including mine). On English wiki (unlike the French one) ''most'' of us are non-native speakers, therefore communication failures happen often.

Best regards,
[[User:Sodin|Sasha]] ([[User talk:Sodin|talk]]) 01:28, 29 March 2012 (UTC)

Hi Sasha,

I think we are all of good faith here: me, my contradictor, and all the people who emitted their opinion. That's not the question.

I think there is a deep problem that this issue has raised. It is being stated that verifiability of sources is for ''experts'' only. That restrains ''de facto'' the verifiability to the contributors of an article, and excludes the ordinary readers. I find the idea extremly unpleasant: for example, If I browse an article on a subject I know little about, and want to have a look in the sources, I would like to find the alleged information, and not have 1) to read the whole article 2) lear the theory, 3) reconstruct a reasoning, and 4) check it is valid. In this pecular case, even with some understanding of the topic, and a good level in maths in general, I was unable to reconstruct the reasoning without the help of the writer of the paragraph: what if he had been on vacation, had left wikipedia, or had been hit by a bus? The wrong version of the formulas would have stayed in the article forever.

Yes, it is easy to miss a word like "twice". I would probably have made that mistake too. This is precisely because it is so easy to make mistakes, even for confirmed mathematicians, and for humans in general, that we should restrain from doing our own research. We should prevent ourselves from getting away from what is written on the paper at the original source. That's the best way of making sure such mistakes won't happen.

Since the result has not been published before, yes, it remains a theorem of the person who wrote it. Maybe the words "theorem of his own" were a bit harsh, but that's ultimately what it is. Bobkov et al. had no interest in bounding the eigenvalues, their focus was on the Poincaré-type constant. I am even wondering if this bounding of the eigenvalue is interesting at all, as it might be too loose an upper value. I tried with concrete examples and got the impression that the comparaison was not bringing a lot of information. Ylloh himself emitted the suggestion that a better result could be reached by taking an other approach (which would make this whole discussion moot, BTW).

I'm not really taking things personnally (well, I do, but I'd like to think there's more to it), I am having a problem with the ''rules'' of the English wikipedia. This exception to the interdiction of original work and to constraint of verifiability that is given to maths is unhealthy. Mathematics have their own "truth", which is called "demonstrability", and there are cases where it can collide with the general Wikipedian principles. This is one of these cases here. When you don't agree with the rules of a community, you leave it. I think it's what I have to do. --[[User:MathsPoetry|MathsPoetry]] ([[User talk:MathsPoetry#top|talk]]) 07:15, 29 March 2012 (UTC)
