Talk:Skewes's number

message: It seems to me that the Demichel result should not be included here, as it appears not to have been properly reviewed and published (i.e., it violates WP:OR).  Can anyone explain why it should stay?  I notice that MathWorld includes it, but I don't think that's a good reason for it to be here.  Doctormatt 00:52, 17 August 2007 (UTC)
replies: text: Good point.  (I'm going to be away from the Wiki for a bit, so I don't have time to look at it in detail.)  It doesn't seem to have been published, and it states it's probable that it's the correct answer, without giving an estimate of the probabilities in question.  — Arthur Rubin |  (talk) 01:00, 17 August 2007 (UTC)

thread_title: Demichel result

message: I believe that the placement of this article into Category:Integers is perhaps mathematically incorrect.  The article gives reference to the "historical" Skewes' number (i.e. the 1933 upper bound proven assuming the RH), which cannot be an integer (or rational number, for that matter) which is implied by the fact that e is irrational.  The article also speaks of a Skewes' number (in some sense) in which I believe there is very little reason to believe that the "true" Skewes' number given by the least upper bound for a violation of the defining inequality is an integer.  It seems to me that it would be very odd and unnatural and perhaps even disconcerting if the least upper bound (Skewes' number) was given by an integer exactly.  For, while the prime counting function takes on only integer values in its range, the logarithmic integral function is continuous (even if defined around its point of discontinuity by the Cauchy principal value of the defining integral), and so moves through a range of values continuously except at prime arguments.  This would seem to indicate that the chances of Skewes' number being an integer are pretty much nil.  If this seems to be too picky, feel free to ignore me, but it seems to me that placing the article in the integers category would likely be mathematically incorrect.  75.204.164.105 10:01, 3 October 2007 (UTC)

replies: text: English is my second language and I'm not good at English grammar but spelling like in Skewes' number seems common to me and OK with Wikipedia talk:WikiProject Grammar#Proper Possessive Nouns which mentions the similar Selous' Mongoose.

thread_title:  Genitive spelling 

message: In 1975 Dr Isaac Asimov wrote a book "Of matters great and small", which contained an 1974 article about the Skewes' number entitled "Skewered!". In this article he elaborates on the magnitude of the Skewes' number and developes a "T number" notation method for trying to judge the relative size of competitive number values.WFPM (talk) 12:04, 9 August 2009 (UTC)

message: The article includes In the unlikely event that the Riemann hypothesis is false ...  Isn't this POV and against Wiki rules? Jamesdowallen (talk) 16:44, 28 January 2010 (UTC)
replies: text: It is tricky to talk about the "likelihood" of a mathematical hypothesis being true or false. But in this context, considering almost all mathematicians would be greatly surprised if RH is shown to be false, and taking into account the vast literature supporting this view (much of it referenced in the RH article), I'd say the statement is supported by the current prevailing view among mathematicians, not that of the editor. The editor correctly reflected that consensus in his comment. Owen× ☎ 17:22, 28 January 2010 (UTC)

Why does it follow that there is a first number. Littlewood proved, according to the wording here, that there is an upper bound. I can't for the life of me see that a first number has to be a consequence of that. What am I missing? All the best 85.220.22.139 (talk) 01:46, 9 March 2013 (UTC)

message: What is really ment by " e^{727.95133} "  ? I presume e to be the base of the natural logarithms , around 2,71. But the exponent - is it 72795133 or 727,95133 ? If the first is corret (which seems likely, then why the dot. I mean 72.795.133 wouldn't be difficult to understand but the "3 dot 5" figures makes me uncertain.

replies: text: It's a correctly used decimal point and shouldn't be changed. You are from a country where a comma is used instead (so am I), but this is the English Wikipedia and a period is dominant in English speaking countries. See our Manual of Style at WP:DECIMAL.
