Ptolemy's Theorem

Hi David

You removed a whole lot of quite important historical stuff on Ptolemy's theorem. Can't say I'm very impressed particularly re the proof via Ptolemy's theorem of a very ancient result which I will quote from Copernicus in Stephen Hawking's "On the Shoulders of Giants."

Moreover the side of the pentagon, the square on which is equal to the sum of the squares on the side of the hexagon and on the side of the decagon (Elements XIII, 10) is given as 117557 parts.

Any appreciation of the history of trigonometry needs to have due regard for the extensive deployment of the Almagest theorem. I think that's what you were perhaps missing when you pulled all the examples I included to that effect. Elements XIII, 10 is an appallingly clumsy way of reaching the above result as compared to the far more elegant proof via "Theorema Secundum".

Daily Mail reference: To be replaced with Times of India citation

Hi David, Thanks a lot for removing the Daily Mail cite from the following article. https://en.wikipedia.org/w/index.php?title=Dinesh_Singh_(academic)&oldid=686452489 (Revision as of 05:28, 19 October 2015)

I was not aware that Daily Mail is not reliable source. After your edit, I did some research and completely agree with you reason and decision.

However, the DUTA ("DUTA is a teachers representative body of the teachers of Delhi University. The elections for its office bearers are conducted every two years.") has made allegations and representations about the authoritarian and megalomaniac administrative style of Dinesh Singh. Therefore, in support of the removed text, please find an alternative reliable source: I am quoting from the news report in Times of India.

"In a second resolution, demanding the dismissal of Singh, the GBM stated that it "condemns the DU VC for his insulting and defamatory remarks about DU teachers, in general, and the School of Open Learning in particular. In an unprecedented display of megalomania, Dinesh Singh has spared neither eminent educationists who have questioned the wisdom of the FYUP nor the parliament where several questions on this issue have been raised"."

One more reliable source - Statesman:

If you agree, can I put back the statement that you deleted and use this cite instead of Daily Mail.

Fact check statement about smallest cubic graph with no Hamiltonian path

I was going to add a statement to Hamiltonian path about the smallest cubic graph that doesn't have a Hamiltonian path (not cycle). I thought this was one of the Zamfirescu graphs with 88 vertices described at [1] but just before I added the statement I realized that paper refers only to planar cubic graphs that are also 3-connected. Has anyone found the smallest simple cubic graph with no Hamiltonian path? I find that the Tutte graph does have a Hamiltonian path (just not a Hamiltonian cycle), and so do snarks like Petersen and other small cases. I recalled and found your family of cubic graphs with polylog longest paths at [2]. Does that family yield the smallest? I couldn't find much in the literature for "untraceable graph" and "nontraceable graph" -- looks like the lack of Hamiltonian paths is not as well-researched as the lack of Hamiltonian cycles. -- 174.152.78.22 (talk) 19:17, 28 November 2015 (UTC)

Planar and cubic but wth no Hamiltonian path

Even for planar graphs, the answer is much smaller than 88; see the figure. I suspect this may be the smallest one (for cubic graphs, unconstrained by connectivity or planarity) but don't have a reference at hand. A similar construction with two lobes instead of three gives an even smaller cubic graph with no Hamiltonian cycle. —David Eppstein (talk) 19:48, 28 November 2015 (UTC)

Fibonacci 's Number

Excuse me, apart of the fact that it would be much more apprechiated a nicer way of describe other people work, can we speak about the erasing of our contribution to the section "in Nature". The work of the astrophysicist Nikolai Kozyrev has been studied, analyzed and experimented for half of a century and it's continuing to be analyzed, by mathematicians, physicists and natural scientists. If there is the need to offer more proof and more references we will, but let's speak about it formally and civilly. There is a reason why many people are researching on this topics and eventhough many of the results are pseudoscientific conquers for a mediatic wave of more misteries then how we had starting, others, like Kozyrev's, Santilli's, Illert's and other works, like those of the italian psysicists Michele Natteri and Francesco di Noto, from the Departments of Earth Sciences and from the Department of Mathematics and Application "R. Cacciopoli" of the University of Napoli, researching on the presence of the Fibonacci number in the String Theory, the conseguences and the physical implications, that you can see also here from other studies: http://www.scientificamerican.com/article/the-strangest-numbers-in-string-theory/

I stand by my edit summary, but given the extra space available here I would like to add that two of references in question are in International Journal of Physics and Astronomy published by Recent Science, listed as a predatory open access publisher by Beall's list, and in Hadronic Journal, the personal journal of notable fringe scientist Ruggero Santilli. Neither can be accepted as a reliable source here and their presence in this material (together with the shout-out to Santilli himself) makes it less credible, not more. —David Eppstein (talk) 01:00, 29 November 2015 (UTC)

Unit disk graph complexity

Hello, the reason for this is in the section "Computational complexity": the problem is whether a graph, given without geometry, can be represented as a unit disk graph. It is also present the Category:NP-complete problems, don't you see? --Horcrux92 (talk) 17:52, 11 December 2015 (UTC)

My feeling is that the category Category:Computational problems in graph theory should be reserved for articles that have a computational problem as their main topic (such as clique problem) rather than ones on something else that happen to mention complexity along the way. Everythiing (or at least everything in discrete mathematics) has an associated complexity; listing them all in the category would be too indiscriminate. And the fact that this one happens to be NP-complete doesn't make it any more or any less of a computational problem than something else with a polynomial time algorithm. —David Eppstein (talk) 17:56, 11 December 2015 (UTC)

Age of rock art at Padah-Lin Caves

Hi, you reverted my edit that described the art at Padah-Lin as 'Holocene'. The previous description of 'mesolithic and neolithic' is taken from reports of the site that are now out-dated. It is no longer accurate because 'mesolithic' is not a chronological period in Southeast Asian prehistory. It has not appeared in any scholarly literature of Southeast Asian archaeology for 30 years and has no definition as a culture-history phase in this region (I read, teach and write this literature). 'Mesolithic' is only meaningful in Europe and the Levant. On the other hand, 'Holocene' is a current and widely used term that refers to a well-defined period all around the world from 11,700 years before the year 2000 AD, up to the present (and so not 'uninformative', as you claim). The Holocene period includes the 'neolithic' period of Southeast Asia, but since the neolithic is not well defined for Myanmar, is it not a good choice to specify a time period. There is no direct evidence for the age of the art at Padah-Lin, so any claim about the age must be vague to properly communicate the lack of certainty about the age estimate. The terms 'mesolithic and neolithic' are almost meaningless for indicating a time period in this region (at best confusing), and their usage here reflects an awareness of the scholarly literature that is at least 30 years out of date. This is forgivable for the literature that was published in the 1960s, and scholars in Myanmar who have very limited access to the internet. But for everyone else, it's not a well-informed choice, so I hope we can agree to move on from 'mesolithic and neolithic' and use 'probably Holocene' instead. What do you think? Comtebenoit (talk) 10:59, 14 December 2015 (UTC)

I think that if you want to use a new date you should use a new source that states that date rather than changing the date but leaving the source of the sentence unchanged. I think holocene should not be capitalized. I also think "these artifacts date from the holocene" is almost completely uninformative because it's true for almost all human artifacts. It would be better to give an approximate range of millennia, because the holocene extends until today and presumably we know that the cave artifacts are older than that. —David Eppstein (talk) 16:56, 14 December 2015 (UTC)

I've checked the primary sources - I mean the report by the excavators. The art is not dated at all, and the word 'mesolithic' is not used to describe the art. To use the word 'Holocene' is not adding a new date, it's using the current technical vocabulary for the same dates. Using current technical terms reduces confusion and ambiguity. Readers of the scientific literature will know that Holocene is properly styled with a capital H because it's a proper noun (you can also see this in the wiki article). 'Holocene' spans almost exactly the periods indicated by the seven radiocarbon dates for this site. So it's an accurate and unproblematic label to describe the period of human activity at this site. To the non-archaeologist, it might seem that 'almost all human artifacts' come from the Holocene. However, there is also the 'Pleistocene', which spans 10k years BP to about 2 million years BP, and there are lot of artefacts in the world from that period also. There is also upper, middle and lower Holocene and Pleistocene, which are routinely used in the scientific literature to indicate greater chronological resolution. In this case, we don't have any greater resolution than 1750 years BP to 13,400 years BP (as reported in the publication by the excavators), so 'Holocene' is quite appropriate, or 'Upper Pleistocene and Holocene' would also be ok. I've also added a new reference for the dates, and some photos. — Preceding unsigned comment added by Comtebenoit (talk • contribs) 04:58, 15 December 2015 (UTC)

I'm happier seeing it spelled out as 1750 years BP to 13,400 years BP (or whatever other dating system you want to use): it's more precise (because it rules out more recent times) and also less WP:TECHNICAL. —David Eppstein (talk) 05:04, 15 December 2015 (UTC)

Ruggero Maria Santilli

Dear David, we do not understand what it needs to be done to consider a scientist a scientist, if, apart of the mathematical skills and the commercial and the practical experience, he've been awarded by so many prizes and recognitions. On his website there are pictures that demonstrate the recieving moments of the prizes. But we know this is kind of useless question with you. Anyway, we found the official source ofr the mediterranean prize, so we will add it.

Concerning Dr Leong Ying. There are not only pictures of them, but you can clearly see from the main page of Dr Ying theory of Twin Universe that his idea are completely in agrees with Dr Santilli's. Apart of this, there sis a video documentare (Reinassance of Cosmology) where Dr Ying speaks about Dr Santilli and in Santilli's website there are many pictures of the entire Princeton Gamma-Tech Instruments team, leaded by Dr Leong Ying, working with Dr. Santilli. At this point we conclude that it is absolutley not fair that more references than these have been asked. We ask that our contribute is manteined. If not, we will write personally to Dr YIng, maybe a direct declaration will be enough as a clear reference.

Thanks

Opeyemi Enoch

Hi David,

I note that you reverted my edit of the Enoch biography page. A more correct history of Enoch's supposed proof would include the crucial role of BBC world service, where a journalist had read that Enoch had been awarded the prize. In turn the BBC (being a trusted source) was copied uncritically by other newspapers. Later the BBC, realizing their mistake, added a header in parentheses saying that the story was based on the assumption that the prize had been awarded.

The websites and blog calling the proof fake, a hoax, or plagiarized (or a Nigerian scam) are not reliable sources of anything. I'm not an expert in Wikipedia but I think there are very strict criteria about biographies of living people, and to say that a source says that someone is a hoaxer is a very serious thing to do. It is just not notable that some bloggers think that the proof is a hoax or is plagiarized, and it is a serious thing to commit to print.

It is clear that there is no proof; the discussion on the Riemann hypothesis talk page is all very responsible and clear about it. The fact that Enoch's university (or supposed university) has no information about his proof, or even about his existence, suggests so. Someone on the talk page (I do not know who) just said clearly that the issue is that although Enoch said that he has a proof, he has not posted one anywhere. This biography article could do the same. Otherwise it ought to, I think, be deleted.

Just on a basis of fairness, also, it is wrong for Wikipedia to repeat accusations of fraud etc which have not been established by any reliable source (and may well be false, there is a difference between being over-confident in your work and being a fraud, and one can interpret Ringos' public statements as trying to be responsible and admit that she may have mistakenly told Enoch in her conference that she understands his proof, and he may have misundersstood the fact that she does not represent the mathematical establishment).

Since you've taken the step of reverting my edit, how about changing the article to make it less like an accussation of intentional fraud on the part of Enoch.Createangelos (talk) 19:05, 20 December 2015 (UTC)

P.S. I don't know if you've seen Nigerian journalists' responses, but they think that the problem is that jealous western scholars are trying to block a valid proof, and that Enoch is a hero involved in a political battle. Such a notion could be really damaging to scholarship in general -- to the way that beginning scholars in China, India, Africa understand how scholarship is done, and also, for instance, the relative trustworthiness of business and science articles versus mathematics and philosophy articles.

In other words, this biography (which gives credibility to bloggers who caricature what good scholarship can be like) gives fuel to those who see scholarship as a power game, rather than as a game of trust or a search for meaningful belief.Createangelos (talk) 19:05, 20 December 2015 (UTC)

P.P.S. If you read a few of Enoch's earlier articles, they are bad but not terrible. They involve very complicated rewritings of the zeta function by trigonometric functions like sin and cosine, and refer to other articles where such equations are established.Createangelos (talk) 19:07, 20 December 2015 (UTC)

My preferred solution would be to just delete the article. There's not much to say besides "he doesn't have a proof, and the media blew it up". See my earlier prod. But the reason for my revert was that your version could easily be read as implying that he really does have a proof that happens not to be public yet. I don't think that's accurate and I don't think we should be implying it. —David Eppstein (talk) 19:50, 20 December 2015 (UTC)

Hmm we can recommend it for deletion, via the deletion log. Have you done that before, i.e. know how to do it?Createangelos (talk) 21:47, 20 December 2015 (UTC)

Ok, I have started a deletion discussion — see Wikipedia:Articles for deletion/Opeyemi Enoch. —David Eppstein (talk) 22:48, 20 December 2015 (UTC)

GA review for Du Friedefürst, Herr Jesu Christ, BWV 116

Hi David, I just did a GA review for the Bach cantata linked above. I think that it's close to passing subject to the revisions I listed in Talk:Du Friedefürst, Herr Jesu Christ, BWV 116/GA1, but it's been a long time since I did a GA review (2007?) so I'd love a second opinion on whether my assessment according to the criteria is likely to stand, particularly since there are two other similar cantatas by the same author that I would then continue to review. Thank you! -- Michael Scott Cuthbert (talk) 17:40, 23 December 2015 (UTC)

Revert of Complete quadrangle intro

I think you were mistaken with this revert. I said "exactly two points", which means two and only two points. And regardless of whether you accept that or not, it's better than the clumsy brain twisted version that you reverted back to. Furthermore, why a revert? Why not correct the error you saw instead of bulldozing my hard work? Zephalis (talk) 03:25, 30 December 2015 (UTC)

My objection was to the part where you got rid of the restriction that the four points have no three on a line. That part was important. Your phrasing "where only two no three of which pass through the same point" is also very clumsy. —David Eppstein (talk) 04:07, 30 December 2015 (UTC)

"where only two no three of which pass through the same point" was a typo, of which could've been easily fixed. There were actually traces of two other versions of the statements that I overlooked because I was quite tired by time I finished.

As for what you say about the "four points hav[ing] no three [points] on a line", I stated that it had "exactly two" points, which covers that there isn't three points. I already said this in my first statement to you as well.

So again, I ask you, why don't you just correct it and not do a revert? I took the time to rephrase it because it's difficult to make sense of the original and I had to go at it piece by piece to get the idea into my head. Even knowing what it is now, the original phrasing is still very difficult to comprehend. I know it's difficult to phrase in a simple, but complete way because it took me a couple hours to phrase it the way I had it, especially since I was also trying to mirror the two definitions so they could be better understood as a whole. --Zephalis (talk) 05:14, 4 January 2016 (UTC)

Deleted section from Fermat`s Last Theorem

Dear Prof. Eppstein. What is the problem with the Appendix where I wanted to share my new elementary research results about the subject ? How do you like these ideas ? Ok now I understood why it was deleted but it does not change the beauty of this result does it ? Happy New Year: White Tiger (talk) 19:07, 30 December 2015 (UTC)

Please see WP:NOR regarding original research and Wikipedia. There are lots of places on the web to share new research results; Wikipedia isn't one of them. —David Eppstein (talk) 02:49, 31 December 2015 (UTC)
