Removal of infobox[edit]

Based upon a discussion at Wikipedia talk:WikiProject Mathematics#"Infoboxes" on number articles, I've removed the infobox from the article. If anyone disagrees, could you please join the discussion there. Thanks, Paul August 14:56, 18 October 2009 (UTC)

I have suggested centralizing this discussion to Wikipedia_talk:WikiProject_Mathematics#Irrational_numbers_infobox and Wikipedia_talk:WikiProject_Mathematics#Infobox_with_various_expansions as it refers to an infobox occurring in several articles. Please go there to build consensus on this edit. RobHar (talk) 19:34, 18 October 2009 (UTC)

Why can't it be 1.5?[edit]

Why can't the answer be 1.5? --66.167.177.92 (talk) 17:00, 6 February 2010 (UTC)

Because 1.5 * 1.5 = 2.25. A simple way to calculate √3 (using continued fractions) is as follows:

1st estimate = 2/1 = 2

2nd = (4*2-1)/(4*1-0) = 7/4 = 1.750

3rd = (4*7-2)/(4*4-1) - 26/15 ≈ 1.7333

4th = (4*26-7)/(4*15-4) = 97/56 ≈ 1.73214

5th = (4*97-26)/(4*56-15) = 362/209 ≈ 1.732057

6th = (4*362-97)/(4*209-56) = 1351/780 ≈ 1.7320513 and so on. --Glenn L (talk) 19:57, 6 February 2010 (UTC)

I suggest we remove this talk entry entirely. The person was clearly making a joke and not asking a question.Tgm1024 (talk) 15:26, 23 May 2014 (UTC)

George washington was born in 1732. — Preceding unsigned comment added by 98.220.130.63 (talk) 23:30, 12 January 2015 (UTC)

Another property.[edit]

It is the non-integer solution to ((xx)x)x = x(xx)x. Should this be added to the article at all? Robo37 (talk) 19:08, 22 September 2011 (UTC)

Poem[edit]

I know this isn't very scientific and all; and I'm not really a big fan of the movie, but shouldn't it be noted that there is a poem titled and "describing" the square root of 3 in the movie Harold & Kumar Escape from Guantanamo Bay? The text can be found here http://www.imdb.com/title/tt0481536/faq#.2.1.16 I know we can't include it verbatim, but isn't it relevant? 217.93.175.214 (talk) 01:53, 25 March 2012 (UTC)

It is common for Wikipedia articles to have a section at the end called "In popular culture". You could create that section with this item -- say "In the movie "..." such and such character [name him] reads [or composes and reads? or composes and the narrator reads?] a poem called "Root 3" [or whatever it's called], in which the square root of three is used as a metaphor for being kept 'out of sight'."

Use of in images[edit]

For any numbers m & n, (2m + 3n)2 - 3(m + 2n)2 = m2 - 3n2, so we get the following series of approximations for : 2/1, 7/4, 26/15, 97/56, 362/209, 1351/780, which gives rise to a method of constructing much more perfect 60° angles in images than the one in the article "Eisenstein prime" in the following image for an image that size.

Americentrism[edit]

It is interesting to learn that "The traditional mnemonic device for remembering this rounded value is George Washington's year of birth, 1732.", but I don't think this "tradition" exists anywhere else than in North America. As far as I'm concerned, I'd rather remember it to be the year of birth of Beaumarchais and Fragonard... I don't know how this should be handled? Arthurprat (talk) 01:10, 20 October 2016 (UTC)

Let me just remove it.–Jérôme (talk) 23:36, 22 January 2017 (UTC)
It didn't make sense anyway, to remember one seemingly arbitrary digit sequence by another. If anything, the root could serve as a mnemonic for the politician's year of birth.–Jérôme (talk) 23:39, 22 January 2017 (UTC)
