User talk:Dmitrii Kouznetsov

Welcome!

Welcome, new editor! We're very glad you've joined us. Here are pointers for a quick start. Also, when you get a chance, please read The Editor Role. You can look at Getting Started for other helpful introductory pages. It is essential for you as an editor to join the Citizendium-Editors (broadcast) mailing list in order to stay abreast of editor-related issues, as well as the mailing list(s) that concern your particular interests. It is also important, for project-wide matters, to join the Citizendium-L (broadcast) mailing list. You can test out editing in the sandbox if you'd like. If you need help to get going, the forums is one option. That's also where we discuss policy and proposals. You can ask any constable for help, too. Me, for instance! Just put a note on their "talk" page. Again, welcome and thank you! We appreciate your willingness to share your expertise, and we hope to see your edits on Recent changes soon.

Background colour

Hello, Supten. I could not find the option to change the background color. At my computer, everything appears too dark. I would like to replace background color either to RGB 1 1 1 or to CMYK 0 0 0 0 . Could you help please? Dmitrii Kouznetsov 00:44, 20 May 2008 (CDT)

One solution is to go to the "My preferences" link at the top of the page and choose monobook for the skin instead of the current default skin. Not exactly what you want but it will give you a lighter background. Chris Day 01:48, 20 May 2008 (CDT)

Oh, much better! Thank you, Chris! Dmitrii Kouznetsov 05:58, 20 May 2008 (CDT)

PS: If you leave a message for someone on your own talk page, they may not see it unless they happen to look at your talk page, or notice it on 'Recent Changes'. Better to leave them on the other person's talk page... :-) J. Noel Chiappa 07:50, 20 May 2008 (CDT)

Dear Noel. Thank you for the suggestion. I should post there if anything urgent. But I post here questions for those who read the 'recent changes' (or are interested in my activity).

I upload pics in formats jpg, gif, png. They are difficult to write, almost imposible to correct errors, have poor resolution and are slow to load. I tried to upload eps figure, but got the following mesage: ".eps" is an unwanted file type. List of allowed file types: png, gif, jpg, jpeg, ogg. What do I wrong? Dmitrii Kouznetsov 20:09, 21 May 2008 (CDT)

name for code

Hi Dmitrii i moved that page to something without the http hereTetrationAsymptoticParameters00. It might be better on the CZ:Code subpage (as you can see we have not really got the code pages going yet, see a brief summary here: CZ:Subpages#Non-text_media ) of an article, which would this go with in the form of Article name/Code/TetrationAsymptoticParameters00? Or maybe I am misunderstanding the role for this page? Chris Day 08:56, 23 May 2008 (CDT)

Thank you, Chris. Name for that pic looks fine. Please, look also at . The source (code) is inside. Sould we extract the code into a separate file? Dmitrii Kouznetsov 09:53, 23 May 2008 (CDT)

P.S.Chris, please, look at CZ:Code. I fill it according to my understanding of your message. Dmitrii Kouznetsov 19:58, 23 May 2008 (CDT)

Code submission

Dmitrii, I opened a discussion http://forum.citizendium.org/index.php/topic,1742.0.html on code submission. For obvious reasons I like to hear your opinion, too. --Paul Wormer 09:47, 27 May 2008 (CDT)

Timeline in biography

Hi Dmitrii, according to the biography section of your user page, your Ph.D. was awarded two years before graduation. Is that so, or possibly a typographical error? ... Peter Lyall Easthope 08:55, 30 September 2008 (CDT)

Thank you, Peter. I just corrected 1978 to 1988. Dmitrii Kouznetsov 16:26, 3 October 2008 (CDT)

categories at citizendium

Hi Dmitrii, good to see you back. Before you put more time into categories I should warn you that we do not use categories in the same way as at wikipedia. All the categories are placed on the articles by the subpages template based on the information in the metadata template. In short there should be no categories on any pages.

Instead of hierarchial category trees we develop the Related Articles subpage to be used as a navigation aid. It would be possible to start a subgroup on mathematical functions. One example of a subgroup can be seen at CZ:Chemical Engineering Subgroup. Let me know if you need more info. Chris Day 03:07, 31 October 2008 (UTC)

Hi, Chris. I do need more information. If I go to CZ:Chemical Engineering Subgroup, I see only the name in curly bracket.. I want to have some place where other mathematical functions are listed; at least to cite them correctly. Where is the list? Could you type/copypast the instruction/(link to the instruction) in category or CZ:Category to explain the use? Dmitrii Kouznetsov 03:38, 31 October 2008 (UTC)

How about CZ:Dogs Subgroup, there is more content there. That is like a home page for users that have a common interest, there are set set rules about how it should be formatted. As for the Chemical engineering one, click on some of the options in the table (most interest for you will be all articles) and you'll see that a subset of articles in engineering are identified. Same for the Dog Subgroup. Note that they also have categories at the bottom of the article to note it is a member of a subgroup. An article can be in three different subgroups; you need to add the subgroup to the Sub1 field in the articles metadata. A subgroups is not restricted to articles within one workgroup in can cross boundaries as well as being a subset of one workgroup. In general these are not like categories in wikipedia but small working groups for authors with a common interest. For hierarchial grouping we use the Related Articles Subpages. Chris Day 12:30, 31 October 2008 (UTC)

The idea here is that categories are not meant for navigation but for organization. In other words, categories are not for people reading Citizendium but for people editing Citizendium. One function for categories here is to collect pages that belong to a Workgroup. For instance, all mathematics articles are in Category:Mathematics Workgroup. So, if you want to check all the changes to mathematics articles (something I do regularly), you can go to that category page and click on the related changes link. Subgroups are an extension to that and can be used if the workgroup grows too large, or if there is a field (like Chemical Engineering) which does not fall nicely in our division of workgroups. In this case, I do not see the need for a Special Functions subgroup; we do not have enough editors working on special functions.

A list of functions is something that a reader could use, so we don't use categories for that. There are two possibilities here to get a list of functions. Function (mathematics)/Related Articles could contain a list of functions with their definitions. For an example, see Category theory/Related Articles which contains a (very incomplete) list of categories; for explanation, see CZ:Related Articles. The other possibility, in case you want to add more information than just the definition, is to use a catalog; in this case we have Catalog of special functions. Cheers, Jitse Niesen 12:50, 31 October 2008 (UTC)

Where are hidden indications of categories? Where to add

• Mathematical functions [r]: Add brief definition or description to specify that

logarithm, tetration and Dirichlet function are namely mathematical functions? Dmitrii Kouznetsov

Your edits at logarithm

Dear Dimitrii. Thank you for your efforts on our article about the logarithm. However, I am afraid that I do not really like the new first paragraph you wrote at logarithm. Citizendium does have some different standards than Wikipedia, and one point where they differ is that Citizendium places more emphasis on making the article easy to understand for non-specialists. See for instance the first section of CZ:Article mechanics Complete, called "The nature or purpose of an encyclopedia article". The first paragraph you added is:

"Logarithm or log, is mathematical function, inverse of exponential function, holomorphic in the whole complex plane, except singularity at zero and cut at the negative part of the real axis. Roughly, logarithm of number $z$ on the base $b$ counts, how many times the base $b$ should be multiplied by itself in order to get $z$. However, this function can be extended to non-integer values of $z$: real, complex, matrices, etc."

Many people are able to understand the idea of logarithms; after all, it's taught at high school. However, the first sentence acts as a huge barrier to those people because it requires knowledge of complex analysis. It is written at a too advanced level. So, I moved the analyticity of the logarithm further down, when we are talking about the complex logarithm, and I removed the rest, because it basically repeats what the next paragraph says.

Your discussion of single-valued versus multi-valued is clearly an improvement. This was sorely missing in the previous version. -- Jitse Niesen 13:43, 31 October 2008 (UTC)

Categories and Log

Thank you, Jitse, for the explanation about categories and logarithms. I looked at dogs. Perhaps, we should begin with more basic category of functors, formulating the articles in the commonly understandable way. As for logarithm, I would suggest to leave in the preamble the short sentence" Logarithm or log, is mathematical function, inverse of exponential function." Then, the numerical examples should be in the section "examples", and there should be section "definiitons". Dmitrii Kouznetsov 07:08, 1 November 2008 (UTC)

Technical problem

Right now, the CZ does not load pics and formulas. I hope it is temporally. Dmitrii Kouznetsov 07:20, 8 January 2009 (UTC)

Again, something happens with the support: right now, the citizendium shows neither pics, nor formulas... Dmitrii Kouznetsov 03:20, 22 April 2009 (UTC)

Round-trip loss

Dmitrii, in Round-trip loss I read the sentence At the self-pulsation, the gain lates to respond the variation of number of photons in the cavity. I have no idea what it "gain lates" is supposed to mean. I tried to access two articles by D. Kouznetsov et al. (I suppose that's you), but unfortunately I am not allowed to read them. Could you explain to me what "gain lates" means? Thank you. --Paul Wormer 07:46, 7 August 2009 (UTC)

Paul, thank you for indication of the poor sentence. I tried to improve the wording and I hope now it is better.

"gain lates": Delays, retards, se tarda, se retrasa,...

I wanted to say, that there is some retardation, delay; the number of excitations needs some time, say, a microsecond, to respond the increase of the relaxation rate due to the stimulated emission. If you understand that do I mean, and you know how to say this better, go ahead.

As for the article, I hope, you can download it from

http://www.ils.uec.ac.jp/~dima/PAPERS/toda.pdf

Dmitrii Kouznetsov 14:21, 7 August 2009 (UTC)

Yes, it is much clearer now. You wrote about "oscillator Toda" (also in your J. Phys. article, thank you for the reference). Because I had never heard of it and was not even sure whether Toda was a person or something else (maybe a piece of hardware) I checked it out, rephrased your sentence a little, and added a reference to show that Toda is (or was) a person. --Paul Wormer 15:38, 7 August 2009 (UTC)

Properties of materials

Greetings!,

There is a discussion of materials properties and whether/how to incorporate them at CZ going on here:

Ellipse

Hi Dmitrii, what do you think about approving the Ellipse? Boris Tsirelson 15:12, 2 May 2010 (UTC)

Approval of cryptanalysis

This is under the Military, Mathematics and History Workgroups. I wrote some text early in the process, but the bulk of the work is by Sandy Harris. Under the rules, however, it can't be a single-editor approval, so I am seeking others to join me. Interested? Howard C. Berkowitz 17:38, 19 June 2010 (UTC)

Dear Howard. I do not understand some things in the cryptanalysis . First, who is attaker, robot or human? In any of this case, the trolling also can be considered as the attacker method: the user gets an "authomatic" message suggesting to confirm (or to change) the password, providing the link to the corrupted site, that emulates the original one. Very stupid, but, according to the amount of the rolex messages, sometimes efficient. Dmitrii Kouznetsov 04:16, 30 June 2010 (UTC)

Relligion?

I see you've introduced a lemma article, relligion. There is a main article on religion. The definition in the lemma, however, is questionable -- axioms, or articles of faith, are inherently not refutable; they lie outside a domain of refutation and proof. Howard C. Berkowitz 15:34, 29 June 2010 (UTC)

Dear Howard. Thank you for your interest. I think, the article religion is poor. I wanted to rewrite it, but first I would like to discuss it with colleagues. My point of view on religion is expressed in the following texts:
http://zhurnal.lib.ru/k/kuznecow_d_j/religion.shtml
http://www.ils.uec.ac.jp/~dima/D/religion.htm
Both texts are almost the same, but first of them allows the online feedback (sorry, the navigation is in Russian, the feedback option is "Оставить комментарий", just above the copyright mark; then the option "добавить", just below the typing frame, the left one, saves the comment). I plan to use the most of the content for the religion article. Could you please read my text and tell me your opinion?
Religions lie outside of refutation, but "inside" the proof. So, the definition should be based on their irrefutability. Should I bring this statement to the discussion of the article religion? Dmitrii Kouznetsov 04:01, 30 June 2010 (UTC)

Yes, I think you should bring it up for discussion. I'm not a Religion Editor, but I would observe that a good many people who are both religious and scientists, such as Pierre Teilhard du Chardin, consider the two to be orthogonal.--Howard C. Berkowitz 20:12, 7 July 2010 (UTC)

the Katyn-2 article

Hi, Dimitrii, as Roger Lohmann has just pointed out on the Talk page of the new article, this article is clearly not acceptable by Citizendium standards. If you can clean it up so that it is a *factual* article and not a speculative one, then that would be great. If not, it will have to be deleted, moved to your own private space, or possibly put into Cold Storage. Please see to this as soon as possible, as CZ cannot afford to have such unacceptable article hanging around for very long. Thanks! Constable Hayford Peirce 18:05, 7 July 2010 (UTC)

Some suggestions are on the talk page, although I've not yet created metadata until the main outstanding issues are resolved. --Howard C. Berkowitz 20:13, 7 July 2010 (UTC)

Sorry for the delay with the respond. I collect more references to make the article more factual. Dmitrii Kouznetsov 07:02, 3 September 2011 (UTC)

New mathematics author

In case you don't get automatic notifications of these things, there is a new author, User:Wietze Nijdam, in your workgroup. Bruce M. Tindall 16:39, 31 January 2011 (UTC)

Tania function

Dmitrii, I have made some cosmetic changes to your article Tania function to (i) make it a full fledged article with sub-pages and a definition, (ii) change some of the font from $\Im ,\Re$ to ℑ, ℜ, and (iii) to put the references in template form in CZ: List-defined references format. Hope that meets your approval. IMO it is more in keeping with the usual CZ layout. John R. Brews 18:25, 25 September 2011 (UTC)

John, I saw your modifications. With subpages the article looks better Should I load more pics for that article? Dmitrii Kouznetsov 05:02, 26 September 2011 (UTC)

Dmitrii: Please judge for yourself if more pics will aid the reader. John R. Brews 05:40, 26 September 2011 (UTC)

Classical mechanics

Dmitrii:

I've made many changes to Classical mechanics and added three figures. The article could benefit from your attention. John R. Brews 11:29, 28 September 2011 (UTC)

Yes, I see. I added there the conservation of mass as a "basic concept" and some wikilinks; in particular, force. The article force should be rewritten. The forces should come from the statics developed by Robert Hooke. Force should be defined as physical quantity, measured with dynamometer, having the following properties: ... (and the long list of axioms about the forces). Some content can be borrowed from Wikipedia.

About the Range of valifity, I have doubts with respect to the sentence

"...but even the number of particles cannot be characterized with as an integer number."

Would it have sense to replace it to

"...but even the number of particles cannot be declared as an integer number."

or to

"...but even the number of particles cannot be characterizes with an integer number."

? Dmitrii Kouznetsov 12:59, 28 September 2011 (UTC)

P.S. I see your updates, in particular, 15:43, 28 September 2011,

"..not only the coordinates of particles cannot be precisely determined, but the number of particles need not be a simple integer. "

http://en.citizendium.org/wiki?title=Classical_mechanics&action=historysubmit&diff=100784319&oldid=100784304

; it looks better. Thank you. Dmitrii Kouznetsov 03:13, 29 September 2011 (UTC)

Reality

You might like to have a look at what's said about mathematics here. There's been some discussion already. Peter Jackson 10:53, 10 November 2011 (UTC)

Hello, Peter. I red the Reality and left my comment at Talk:Reality#Mathematics_and_Reality.

Do you think that the concept of reality suggested in that article is refutable?

From my side, I suggest the

http://tori.ils.uec.ac.jp/TORI/index.php/Place_of_science_in_the_human_knowledge and

http://tori.ils.uec.ac.jp/TORI/index.php/Mizugadro_number

Do you think some parts of these article should pe copipasted at CZ?

Material deleted

Several pages and images have now been deleted due to "Blatant and obvious violations of the Citizendium neutrality policy" and questionable copyright status, as per directives from the Managing Editor and in accordance with existing rules. The Constabulary is therefore compelled to issue a formal warning. Further violations will result in your account being blocked. Thank you. John Stephenson (talk) 13:14, 2 January 2015 (UTC)

Dear John Stephenson.

You have deleted several articles mentioned; you may be interested to know my opinion about this.

I think, you make error, abusing your privilege to delete my contribution.

Here, I indicate only one example; perhaps, not the most important, but easy to understand:

You defend the author property, copyright, on the wrong image from the Soviet textbook.

I have indicated, that the figure is wrong. This is not offence; everyone can see it.

You did not even try to discuss it.

To me, your activity looks destructive, far from neutrality and politically-motivated.

Sincerely, Dmitrii Kouznetsov (talk) 19:18, 2 January 2015 (UTC)

As I have stated above, this is a Managing Editor directive, as he and the Council are responsible for content, i.e. not my decision. Concerning the image you mention: you said yourself in its description that it had no free licence. All I can suggest is that you appeal to the Council for your material to be re-instated. John Stephenson (talk) 20:00, 2 January 2015 (UTC)

First, I want to understand your point of view. You seem to protect the authors of the textbook and Russian ministers of education against critics.. Do you think, that your actions should be qualified in any other way? Dmitrii Kouznetsov (talk) 10:45, 31 May 2016 (UTC)
