Manual of style edits
Hi, I rebutted your manual of style edits. I think you misunderstand what mathematicians mean when they say "Its easy to show...". It is not a belittlement of the reader and must not be taken as such; it is rather a statement about the length of a proof, the excercise of which is left to the reader. linas 04:28, 2 September 2005 (UTC)


 * I replied to your note on my talk page. But I liked my reply so much, that I'm posting a copy here:


 * In mathematics, there is an immense raft of specialized jargon. The phrases "Clearly," "Obviously," and "It's easy to show that ..." are a part of that jargon. Although they resemble the English language, thier true meaning is subtle.


 * Mathematicians often encounter head-scratching claims in the papers they read, claims that make them stop and wonder "what does this mean?", and "how could this possibly be true?", or "how could the author presume such a thing without any justification whatsoever?". These head-scratchers come in two basic varieties: the simple, forehead-slapping, "duhh, of course" kind, and the complicated kind. These two types can be very hard to tell apart, and one can loose hours or days on them. There are some well-known stories of strong mathematicians who spent weeks on problems only to wake up in the middle of the night with a "duhh of course" inspiration. The phrases "Clearly," "Obviously," and "It's easy to show that ..." are used to indicate to the reader that what follows is of the forehead-slapping variety. They do not imply that what follows is somehow "easy"; its usually not -- if it was actually easy, then the author wouldn't need to coach the reader with this "com'on you can do it" pep-talk.


 * Yes, texts that use these phrases may seem intimidating, but that comes from an unfamiliarity of math jargon. No one expects that the claim following an "Obviously..." will be obvious to anyone wihout years of preparation. linas 21:14, 20 February 2006 (UTC)

The two moons Shri Krishna Chaitanya and Shri Nityananda are my life and soul. I, Vrindavana dasa, sing the glories of Their feet. —Preceding unsigned comment added by 95.132.82.156 (talk) 14:04, 2 July 2010 (UTC)

Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, please do not add promotional material to articles or other Wikipedia pages, as you did to Convergent series. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted. Take a look at the welcome page to learn more about Wikipedia. Thank you. JohnBlackburne wordsdeeds 02:42, 24 August 2010 (UTC)

Not inappropriate
The mentioned edit to Convergent series was not a soapbox, autobiographical, advertising, propaganda, opinion, recruitment, or scandalous. It was neutral and relevant.

I am not a new user; I have been editing Wikipedia for over half a decade. Crasshopper (talk) 05:47, 24 August 2010 (UTC)


 * As noted at WP:ELNO links to blogs should usually not be added to Wikipedia. This is especially true of your own blog, and especially true of one which is largely promotional, as implied even just by the name that appears in the article, "hire me because I'm smart". But it would be true just because it's a blog, and I've removed and seen links to blogs removed just because they are links to non-notable blogs, Wikipedians or not. -- JohnBlackburne wordsdeeds 08:41, 24 August 2010 (UTC)


 * The title of the blog is not permanent (will change to Anti Bourbaki Blog or Human Mathematics or ... something else) and if you read beyond the self-mocking title you would notice that >50% of the posts are genuine mathematics. The content I linked to is "minimal, meritable, and directly relevant to the article". Any undergraduate learning series for the first time should know the heuristic break-points mentioned in the linked material.  Moreover, since the breakpoints are subjective, they cannot be included in the scientific discussion of series (as WP:ELMAYBE requires).


 * Tumblr provides a convenient CMS; a "blog" like you're talking about discusses personal material, not science.
 * Crasshopper (talk) 09:06, 24 August 2010 (UTC)


 * A blog can be on anything, which is part of the problem with them: they can range from only containing authoritative postings fit for publication (some are made into books) to personal nonsense, with everything in between. There are so many of them that that they would overwhelm many articles if added. And unlike say content in text books and peer reviewed journals there's no easy way to assess the quality or reliability of most of them. So the default is to exclude them. And that is before the other concerns, that your blog is largely promotional, even in the domain name, and that adding it yourself is a conflict of interest.-- JohnBlackburne wordsdeeds 15:58, 24 August 2010 (UTC)


 * You'll notice that I haven't re-added the link during this discussion. The blog title and domain name are going to change; the current status is a self-mocking holding name until I think of an actual name for it.  Eventually the content won't be in sequential "blog" format either.  But all of the decoration is irrelevant.  The math is correct, it's neutral, and it's useful to those who would be looking at Convergent series.  It's verifiable by anyone who has taken college calculus and does not need to appear in a journal.  You are welcome to judge a book by its cover if you wish, though. Crasshopper (talk) 17:35, 24 August 2010 (UTC)

Taleb
Please do not add "new books coming out" until they have actually been published. the relevant policy is that Wikipedia is not a Crystal ball. Please be very careful with this article, for which there have been repeated concerns of promotionalism and NPOV. I am trying as an administrator to ensure that it is the strongest article that meets our rules; articles that list an excessive number of works, especially unpublished or minor works, do not give a strong impression. FWIW, I have no particular interest in him or his subject(s), one way or another, but I do quite a bit of work here making sure we do not descend into promotionalism.

Jacopo Saltarelli
Weasel words/Original research:   I'm having a bit of a problem with this. It was me who added the statement that the quoted author had "probably overlooked" the fact hat although "the "profession of model" didn't exist (if by "model" you mean clothes-horse), that there were artists' models, professional or not.  It can be reasonably presumed that when Saltarelli is described in literature as a "model", the sort referred to is an artists model, not a photographic or catwalk model.   However,the statement has been quoted and reliably refrenced. So, as an art historian who knows that artists used models, I either have to delete the referenced statement because, it is erroneous, or counter it with something that looks like mere opinion.

In your opinion, should I delete the stupidity, or turn my comment into a footnote, or simply state that what is meant is "artists' model"?

Amandajm (talk) 06:40, 7 April 2012 (UTC)


 * The only reason that it requires qualifying is that an editor has put into the article a statement that a particular author says that the "profession didn't exist". The statement has a reference.  Other books call him a "model".
 * The difficulty is that the statement that the "profession" of model didn't exist may well be true, but that doesn't mean that Saltarelli wasn't a model. He may not have been a "professional" prostitute any more than he was a "professional" model.  He seems to have been an apprentice goldsmith,  who earned a bit of money on the side.  Regardless of whether people modelled as  profession,  it is a fact that people modelled for artists and were almost certainly paid to do it. We know that Leonardo searched the streets of Milan, looking for someone to use as a model for Judas in the Last Supper.
 * I find this all a bit annoying. Saltarelli has virtually no entity except as someone who may or may not have solicited Leonardo, and a number of other people, for sex.  That is all we know.  He is entirely non-notable! The matter of whether he was or wasn't a professional model really isn't very important.
 * Amandajm (talk) 17:01, 7 April 2012 (UTC)
 * Th word "profession/al" ought not be mentioned. Whether or not any type of modelling was perceived as a "profession" is a red herring.  Saltarelli could have modelled for artists and been paid for it on a purely casual basis.  To imply it was his "profession" discounts the fact that he seems to have been an apprentice goldsmith.  Regardless of whether he was a goldsmith, he could have modelled for artists on a purely casual basis. Whetehr the "profession" existed ought not to have been introduced to the article. It is irrelevant. Amandajm (talk) 14:34, 14 April 2012 (UTC)

Please Help!

Recently, Tking 1974 added an "other uses" page to the "expense ratio" page that is very clearly for a term with an entirely different meaning, "operating expense ratio". Rather than just delete that particular edit, I added information that provided a very clear distinction between the terms "expense ratio" and "operating expense ratio". Mean as custard, in my opinion, improperly removed my contributions. Since operating expense ratio has a distinctly different definition, I believe either my edit should be reinstated, or the "other uses" section deleted entirely from that article.

Very clearly, at the very least, the additions I had provided should be included with the other uses section that was added....and possibly a new page with "operating expense ratio" as a title should be added.
