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? -- (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 (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)


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 I know we can't include it verbatim, but isn't it relevant? (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.

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)
