Dear David Epstain, I'm a PhD candidate in Anthropology at University of Verona, Italy. In my research I use some Social Network Analysis and Visuazlization and I have found out a circular layered layout, written for gephi (http://gephi.github.io/) by Jaroslav Kuchař (Information Technology, Czech Technical University di Praga). Here is the code address (https://github.com/jaroslav-kuchar/Layered-Layout) and the plugin address (https://marketplace.gephi.org/plugin/layered-layout/). I believe insert information about this plugin could enhance the wiki page, but I am not enough technically skilled to write about it with the same level of expertise you had in the page (and I don't have the time right now to study it more). So, I just wanted to inform you about this layout, it might interest you. Thanks for the page. Miromarchi (talk) 09:56, 3 April 2015 (UTC)
I was wondering if you might consider commenting on this AfD Wikipedia:Articles for deletion/Nim (programming language) as a professor of computer science and an administrator. I would appreciate your expert opinion on this matter, whichever side you take. ― Padenton|✉ 23:12, 4 April 2015 (UTC)
Question regarding your revert of my contribution to the Binary Number article. It is my understanding that Pingala's theory predates those documented in the article. I therefore ask why the point regarding Pingala's system has been deleted? I am of the opinion that the historical section within this article should be written in chronological form. As you mentioned in your summary of the deletion, the facts are correct and the content is relevant, which is why I am a little confused by the revert. I totally appreciate the fact that you are an expert at an academic institution, which is why I have taken such a subtle approach to reach out (just in case I have misunderstood something). I look forward to working with you. -JG (talk) 11:02, 9 April 2015 (UTC)

Hi. I'm helloholabonjournihaonamasetgutentag. I noticed that you made the Tau (mathematical constant) page into a redirect into Pi. Why? I think that Tau should have its own page as more and more people are using it. Please check out [this video]. Thanks for considering!

The edit was to reflect that the school is a series of buildings and land, and it was the humans that occupy them that created the controversy, not the school itself. Point being that the school itself can not "do anything" without the help of people. --talk→ WPPilot 16:57, 26 April 2015 (UTC)

Hi; I notice that in User:David Eppstein/monobook.css you have the CSS rule
.ambox-Orphan{display: inherit !important;}
- please note that there is an error in this (almost certainly copied from an old version of Template:Orphan#Visibility) which causes incorrect display in some browsers.
To check this, visit this page and look at the second bullet (the one that precedes the text "This article is an orphan ..."). If this bullet is not in the same alignment as the other four, but displaced to the left, you can fix it by altering inherit
to table
in the CSS rule mentioned earlier. If that doesn't work either, alter it to block
.
Template:Orphan#Visibility has been amended. --Redrose64 (talk) 19:44, 1 May 2015 (UTC)

I've took a look at the historic of your contributions and recognized you as a very valuable contributor to this project. The amount of work you do for Wikipedia is really impressive and of very high quality. Anyway, here on Wikipedia there is always work to do, haha, it's really a never ending flow. :D I hope you to continue strong and forward! Sincerely, Lolaszvodikech (talk) 04:36, 22 May 2015 (UTC) |
Hi David,
I see you reverted my edit because you seem to disagree that tangent is ambiguous. If you have a look at tangent, you can read that the tangent is the line that just touches the curve and that he word tangent comes from the Latin tangere, to touch. Finally it says that the tangent at a reference point may still not be uniquely defined because the curve is not differentiable at that point although it is differentiable elsewhere. In this case the left and right derivatives are defined..., which fits only in very few case with what is needed in the case of the realeaux triangle. The line of the box at Curve of constant width are not tangent in this usual mathematical sense, perhaps that is also why that page uses a more elaborate formulation: the perpendicular distance between two distinct parallel lines each having at least one point in common with the shape's boundary but none with the shape's interior, since most of the time not all of these parallel lines are tangent lines in the usual sense. I hope you will agree that there is a problem with using tangent as it means something more restricted than what is needed here. The full definition from Curve of constant width is good, but perhaps a bit long for using in its entirety... Do you have a suggestion for how to proceed? MarSch (talk) 08:18, 22 May 2015 (UTC)
Dear Dr. Eppstein,
I have a problem with a possible misunderstanding.
My contribution is not about "original research". The phrase "original research" (OR) is used on Wikipedia to refer to material—such as facts, allegations, and ideas—for which no reliable, published sources exist.
My contribution also cannot be considered as "spam and advertising": Latest revision as of 17:28, 22 May 2015 (edit) (undo) (thank) Joseph2302 (talk | contribs) (Reverted 2 edits by Lev Kalmykov (talk): Remove spam and advertising. (TW)).
My contribution is appropriate and accurate. It's not about my biography, my personality and it does not contain anything other than a title of the article published in the peer-reviewed journal with IF=1.231 which is indexing in 27 bibliographic bases and another title of the article published by 2013 in the peer-reviewed journal with IF=1.503 which is indexing in 7 bibliographic bases.
Re-posting was caused by the insufficiently correct deletion of this adequate contribution by David Eppstein.
In more details:
The first removal of my contribution “16:01, 21 May 2015 David Eppstein (talk | contribs) . . (56,031 bytes) (-494) . . (Undo WP:REFSPAM, WP:TOOSOON to tell whether this is of any significance)” looked biased because I provided a referenced link to the peer-reviewed article (Kalmykov LV, Kalmykov VL (2015) A Solution to the Biodiversity Paradox by Logical Deterministic Cellular Automata Acta Biotheoretica:1-19 doi:10.1007/s10441-015-9257-9) and it is already indexed in PubMed: http://www.ncbi.nlm.nih.gov/pubmed/25980478. Within a month, it is expected that the article will be indexed in all 27 bases. Besides, this contribution directly corresponds to the title of the published article and Wikipedia's section.
The second removal of the contribution “15:31, 22 May 2015 David Eppstein (talk | contribs) . . (56,031 bytes) (-494) . . (Undid revision 663513765 by Lev Kalmykov (talk) same reason. Primary source with absolutely no citations on Google scholar.)” also looked biased because Acta Biotheoretica has Impact Factor 1.231 and indexed in Science Citation Index, Science Citation Index Expanded (SciSearch), Journal Citation Reports/Science Edition, PubMed/Medline, SCOPUS, EMBASE, Google Scholar, EBSCO, CSA, CAB International, Academic OneFile, Biological Abstracts, BIOSIS, CAB Abstracts, CSA Environmental Sciences, Current Contents/ Agriculture, Biology & Environmental Sciences, Elsevier Biobase, EMBiology, Gale, Geobase, Global Health, INIS Atomindex, OCLC, SCImago, Summon by ProQuest, The Philosopher's Index, Zoological Record.
I also provided a link to another peer-reviewed article (Kalmykov LV, Kalmykov VL (2013) Verification and reformulation of the competitive exclusion principle Chaos, Solitons & Fractals 56:124-131 doi:http://dx.doi.org/10.1016/j.chaos.2013.07.006). It was published in 2013. Chaos, Solitons & Fractals has Impact Factor:1.503. This journal is indexed Science Citation Index; Scopus; Current Contents/Engineering, Computing & Technology; Mathematical Reviews; Research Alert; SCISEARCH; Zentralblatt MATH
This contribution also directly corresponds to the title of the article and Wikipedia's section.
Verification of the competitive exclusion principle and biodiversity paradox were the long-standing problems in theoretical ecology.
I am a novice at Wiki and I need more correct and understandable arguments. May I cite these articles using their titles and referenced links (as I did in these cases) for example after a month when our article from Acta Biotheoretica will be indexed in all 27 bibliographic bases?
Thank you for your time and consideration!
Sincerely,

I don't think WP:SNOW applies here; not every vote was "keep". Additionally, WP:BIOFAMILY says that one doesn't become notable solely for being related to someone famous.

Was this edit summary really necessary? Looks like a personal attack to me. Please don't do it again. -- WV ● ✉ ✓ 00:20, 7 June 2015 (UTC)
"Winkelvi is known as a Wikipedia editor who likes adding phrases known to be redundant"Do you have something factual to back this statement up? Because, if not, it's plainly and simply a personal attack. I'm fine with people criticizing my writing -- as long as it doesn't stray into attack territory. I'm fine with people amending my writing as long as it's factual, germane, and an improvement. ~
I think the three uses of "known as" in that edit summary are very obviously intended to add no meaning (just as the "known as" in the article text added no meaning, and in that sense was redundant). That was the point of the edit summary as I read it: to emphasize that it adds no meaning to use "known as" in that way. It is not a personal attack in any germane sense. — Carl (CBM · talk) 00:53, 7 June 2015 (UTC)

Recently I have created List of mathematical artists. But unfortunately it is being considered for deletion. Could you help to improve this article? D-4597-aR (talk) 15:02, 7 June 2015 (UTC)

Greetings Mr Eppstein
Do you mean the hook as of itself or the material in the article supporting the hook? I have to personally give my opinion that the hook itself is too short and concise to possibly look like a copyvio, and I have made a change in the article material if that was the problem. If you have the time to give comments on the template about where exactly the changes should be made, I would be very grateful. '''tAD''' (talk) 13:58, 15 June 2015 (UTC)

Thanks for your comments! I addressed some issues, but I did not see a way to change copyright info on the photos. The whole upload process was very confusing and I am not completely comfortable having those photos in the commons. Is there a way to use a photo without uploading to the Wiki Creative Commons? What exactly are you looking for when you want things to be "better sourced"? I think the personal details are important to those interested in the history of women in science. Other women scientists of similar age, such as Sylvia Earle and Jane Goodall, did not stick to one spouse the way Audrey did, and did not put their children at such high priority. I am very unclear how this normally works, but I moved your comment to a talk page for the Audrey page, and also wrotehere on your talk page. Let me know which is better? Any feedback/advice much appreciated! Thanks again!Soilmicro (talk) 01:14, 20 June 2015 (UTC)Soilmicro

Helloooo !
I'm here to talk about your revert on the "Chang Graphs" page. First, let me mention that I am a total beginner here.
I am a contributor to the software Sage (http://www.sagemath.org/) and I got very interested by semantic databases recently. I have been using wikipedia through dbpedia (http://dbpedia.org), which I try to "link" with Sage. At the moment, it involves listing all graphs that Sage can build and matching them (in a future 'open' database) with Wikipedia entries.
Now, several attributes are defined in dbpedia for "individual graphs" (number of vertices, number of edges, chromatic numbers), but of course this has absolutely no meaning whatsoever if what Wikipedia registers as an 'individual graph' (for which those parameters are defined) is a family of graphs (whose elements may have different number of vertices/edges/chromatic number). You just cannot manage a family of graphs as you would manage an individual graph, and this is the difference (which shows in a semantic database) that I am trying to fix here. I have the same problem with these other entries:
https://en.wikipedia.org/wiki/Ellingham%E2%80%93Horton_graph
https://en.wikipedia.org/wiki/Petersen_family
Both mathematically and semantically, it makes more sense to consier them as a family of graphs. It is particularly obvious in the latter case that a classification as a "Graph Family" would be more appropriate.
It seems that we also have many graphs in Sage that are not known to wikipedia, and which I will add soon. Some, funnily, are known to the french wikipedia. Is it proper to translate those pages to english in such a situation?
Thanks,
Nathann — Preceding unsigned comment added by Nathann.cohen (talk • contribs) 09:47, 23 June 2015 (UTC)
Would you have anything against filing them under "Graph Families"? I can hear that you do not mind having finite collections of graphs under "Individual Graphs", but if you do not mind to bend the definition this way, why wouldn't we move them to "Graph Families"? There is nothing in mathematics that supposes that a family is infinite, and clearly this is where the "Petersen Family" should be filed. That would also be more correct semantically in dbpedia.
Thanks,
