Riemann hypothesis

Dear David,

So i was wrong again, i apologise. The upshot of the graph wil now be mysterious to many. Could you please briefly indicate in the caption where we can find the zeros in the plot, if it is not at crossings for zero values? And explain this somewhat? Thank you, Hansmuller (talk) 06:49, 1 October 2022 (UTC)

Our actions crossed in time, you explained in the caption. Still "touch the axis" means being zero., right? You didn't want me to say that? Cheers, Hansmuller (talk) 06:54, 1 October 2022 (UTC)

Apery's Constant Update

Dear David,

I'm able to verify the result I added to the article using identities for the Taylor Series of $-\psi _{0}(1-x)$ and some results in umbral calculus, but I'm not aware if there's a published result showing it. Admittedly, I hadn't been diligent in making sure that any results I found to follow from known results were publicly available.

I'm new to Wikipedia, but I do want to contribute what I've found when I have the chance. Is there anywhere to show the proof for my result, or if not, where can I look for sources that would verify this result? Again, I don't know at this point. 70.108.1.71 (talk) 00:04, 4 October 2022 (UTC)

Wikipedia content is not based on mathematical proof but on published sources. If you cannot find this material in publications e.g. through Google Scholar or zbMATH, but want to make it known, Wikipedia is not the right place for that. Maybe write and publish expository article on the many series representations of zeta(3), and include it there? —David Eppstein (talk) 00:16, 4 October 2022 (UTC)

DYK for Doyle spiral

On 19 October 2022, Did you know was updated with a fact from the article Doyle spiral, which you recently created, substantially expanded, or brought to good article status. The fact was ... that circle packings in the form of a Doyle spiral (pictured) were used to model plant growth long before their mathematical investigation by Doyle? The nomination discussion and review may be seen at Template:Did you know nominations/Doyle spiral. You are welcome to check how many pageviews the nominated article or articles got while on the front page (here's how, Doyle spiral), and if they received a combined total of at least 416.7 views per hour (i.e., 5,000 views in 12 hours or 10,000 in 24), the hook may be added to the statistics page. Finally, if you know of an interesting fact from another recently created article, then please feel free to suggest it on the Did you know talk page.

Sergey Kislitsyn

I don't understand how a draftification of a poorly-sourced article is "hostile". Drafitifying is much better than giving the page 5 maintenance tags or tagging it for deletion because it gives the author a chance to work on the article without somebody else doing one of those two things. I also don't understand why it's a problem for me to move articles created by older editors to draftspace—it should be a problem that they as a veteran editor created a BLP sourced by a single external link in the first place. If someone moved one of my articles to draftspace, I wouldn't be frustrated with the person who moved the article to draftspace, but rather myself for letting me create such an article that would require them to do that move to draftspace despite me having years to understand the basic article guidelines. Waddles 🗩 🖉 16:32, 21 October 2022 (UTC)

Draftification and user-talk templatification is a way of telling editors we want them to go away and we aren't even going to go to the effort of a personal message. It is unquestionably hostile. That is appropriate for spammers but not for good-faith and knowledgeable contributors. If you don't understand these things you should find something else to do where your lack of understanding will not be biting new editors and pushing them away from the project. Yes, that sentence was also hostile. I react with hostility when people act in ways that damage the project. —David Eppstein (talk) 16:34, 21 October 2022 (UTC)

Draft:Peter L. Antonelli (Mathematician)

Hi David -- Could I ask you to take a quick look at the above draft, which has been languishing for months and I think has been abandoned by the creator, after being given the usual bad advice. The GS profile looks quite healthy to me and the subject is deceased. Many thanks! Espresso Addict (talk) 05:27, 25 October 2022 (UTC)

Ok, cleaned up and promoted. I see what you mean about the bad advice and its bad results. —David Eppstein (talk) 06:30, 25 October 2022 (UTC)

Tetsuji Oda

Hi David when I click on the link to the archived source for this article I see a single short page listing just six new fellows, of which Oda isn’t one. Your deprod comment mentions 34 pages of something. Are we looking at the same thing? Mccapra (talk) 06:14, 26 October 2022 (UTC)

You did click on the archive link, not the original, right? It's a 50-page pdf file. —David Eppstein (talk) 06:17, 26 October 2022 (UTC)

Ah ok. Yes I clicked the archive link. Thanks Mccapra (talk) 06:23, 26 October 2022 (UTC)

Though when I click in the original it brings up a dead page and when I look at the IEEE page I still can’t find the list you’re referring to. Mccapra (talk) 06:30, 26 October 2022 (UTC)

https://web.archive.org/web/20150906035742/https://www.ieee.org/membership_services/membership/fellows/2015_elevated_fellows.pdf is a 50-page pdf listing Oda on page 34. Searching by name on https://services27.ieee.org/fellowsdirectory/home.html also finds Oda. The archived link is now a deadlink, that now gets redirected to some landing page instead; that doesn't invalidate it in any way. —David Eppstein (talk) 16:40, 26 October 2022 (UTC)

Still interested in Leonhard Euler?

I found some good sources, in German though, but as to me they seem really good and are easily online accessible. Here, here and here are letters between Euler and some of his colleagues.

Coordinatewise version of graham scan

I think keeping the sentence "If the points are already sorted by one of the coordinates or by the angle to a fixed vector, then the algorithm takes O(n) time." makes it awkward to beginners (https://en.wikipedia.org/w/index.php?title=Convex_hull_algorithms&oldid=1123252177). I've spent hours trying to understand why Graham scan would work by just sorting by coordinates rather than the angles, until I finally found out that you also need to tweak the algorithm in order to use that. Andrew's algorithm is only a couple bullet points below, if there were any references to that or if the sorted coordinates was not mentioned I would have found things out much faster.

It may be easy to understand for a specialist, but it is confusing for a beginner. 2A02:C7F:F0E5:8A00:2E88:9E30:3864:E53D (talk) 16:21, 23 November 2022 (UTC)

The problem with your edits is not that they were referring to Andrew's algorithm. It is that you were doing it by adding links on the text of the article, to another site. That is not allowed in Wikipedia articles. References in footnotes are ok. References by links on article text are not. The proper reference for Andrew's version of Graham scan (I don't think of them as different algorithms) is given in the Graham scan article, as a footnote. —David Eppstein (talk) 16:53, 23 November 2022 (UTC)

Kirsten Wickelgren

Thank you for the message. I've linked an obituary of her father, which appeared in the Harvard Class of 1960 50th Anniversary Report. This connects her unambiguously to all of her immediate family. I cited a published biography of her great grandfather, that includes descendants through her mother's generation and spouses of descendants through her grandmother's generation. This connects her mother to her grandmother and her great-grandfather. Is that sufficient sourcing? QBobWatson (talk) 22:49, 23 November 2022 (UTC)

Probably sufficient re sourcing. But it certainly does not belong in the lead. It is the least important part of the biography, not the most important. Also, please pay more attention to formatting citations consistently with the others in articles. —David Eppstein (talk) 23:35, 23 November 2022 (UTC)

Emma Lehmer

You mentioned (in 2012) a reference to Emma Lehmer discovering the then-largest-known set of twin primes. Do you have a copy of that reference (J. Recreational Math., 1970)? It doesn't appear to be online. Jonboy (talk) 21:29, 4 January 2023 (UTC)

No, sorry. —David Eppstein (talk) 21:52, 4 January 2023 (UTC)

Reversion

Hello, You reverted someone's addition to Ron Schnell recently. I agree with you about the published article. I would like you to reconsider the reversion relating to the Johnny Depp trial. The testimony was watched by 500 million people. Also, you mention that it should not be mentioned twice (with which I also agree), but you deleted both the first and second time it was mentioned. Please consider putting one of them back. Ron Schnell 17:30, 5 January 2023 (UTC)
