Where does sqrt(-1) go? 67.78.183.206 19:07, 2 January 2013 (UTC)

It goes up (literally above 0). A number line can be extended to a complex plane with sqrt(-1) as the unit of measurement in the vertical direction. Or at least, that's where it actually goes. I don't know where Randall would put it. 75.69.96.225 01:04, 5 March 2013 (UTC)

I'm sorry...are you indicating the ACTUAL location for an IMAGINARY number? -- ‎74.213.186.41 (talk) (please sign your comments with ~~~~)

Yes, that's exactly where it is (up to switching clockwise for counterclockwise). There is nothing strange about providing a location for imaginary or complex numbers, the location described is logical, and the adjective 'imaginary' is an artifact of nomenclature and nothing more.173.48.140.216 20:40, 30 March 2013 (UTC)

In fact, complex numbers are nearly more real than real ones! Complex analysis really opened my eyes to how much "stepping out" can help in solving problems. The complex notion of analyticity yields fruit in real analysis. Extensions to hypercomplex numbers are weirder, however. --Quicksilver (talk) 20:27, 17 August 2013 (UTC)

Analyticity must be an imaginary word, and therefore would be found one unit directly above any dictionary. 50.203.89.169 14:19, 9 October 2013 (UTC)

Oh my god, I can't believe how hard I laughed at that. Would an imaginary friend actually be above you then? I'm going to use that sometime. 108.162.219.61 21:25, 24 April 2014 (UTC)

Is unexplored a map reference? Halfhat (talk) 17:53, 13 January 2014 (UTC)

Note that the digits 5 and 6 do not show up on any of the numbers in the comic, reinforcing the fact that the integers 5 and 6 are unexplored. Blitzer (talk) 02:34, 15 May 2014 (UTC)

So the 5th digit of pi can not be known either? Tharkon (talk) 03:56, 12 July 2014 (UTC)
The whath digit of pi? 108.162.215.119 01:59, 1 January 2015 (UTC)

Thank God (or someone else, I'm not choosy) that the SCP link here still works. The rest of the site's gone private. 108.162.250.223 (talk) (please sign your comments with ~~~~)

It appears that Wikipedia had noticed the implications of the title text here. The message now says that it might never be complete, but can be expanded with reliably sourced articles. I'm not 100% sure it's due to Randall's involvement, but I like to think so. --141.101.104.17 22:01, 9 December 2014 (UTC)

I am not American, but the linked Wikipedia Article does not support the claims about president's day being observed between the 2 birthdays of Washington and Lincoln in general, but just that in some states Lincoln is also referenced on that day. Even if it was put as a day between these birthdays by definition and on purpose, I do not see the reference here... Especially as this number is given as specific, unlike presidents day, which can occur in a range of days... Someone who knows more of American culture, and also what "observed" (which would link it to holidays....) can mean in English language please revert this. --Lupo (talk) 12:41, 18 September 2019 (UTC)

The link to "bleem" does not work for me, but the word can be found in Urban Dictionary. ——172.69.63.161 02:12, 21 August 2020 (UTC)

While 8 is not the "largest even prime", 9 is in fact the lowest odd composite number. So 8 is the largest in the unbroken line of natural numbers that are even or prime (or whatever 1 is). 141.101.76.205 10:48, 18 January 2023 (UTC)

1 is a unit. With natural numbers, that's literally just 1, but when you extend the concept of primes to arbitrary rings there's more like that so it's worth giving a name to. DanielLC (talk) 06:17, 15 May 2024 (UTC)

Surely Gird is a reference to Bleem and to the philosophical concepts of Grue and Bleen? Just as they derive from Blue and Green, so we would have Bird and Gleem. 172.71.98.86 20:33, 29 November 2023 (UTC)

1 pixel ~ 0.012 start of unexplored zone ~ 4.381 end of unexplored zone ~ 6.714 length of unexplored zone ~ 2.333 coincedence? plushie fan (talk) 00:07, 30 November 2023 (UTC)

For f(f(x))=11x, one example is: write x=a*11^b where a%11>0. If a%11 is odd, let f(x)=(a+1)11^b; otherwise a%11 is even, let f(x)=(a-1)11^(b+1).172.71.222.235 03:01, 1 December 2023 (UTC)

Even simpler, let f(x)=-x for x<0 and f(x)=-11x for x>=0.172.70.175.54 17:46, 3 December 2023 (UTC)

How is Tau also called "Twice Euler's constant"? IMO, the name Tau, or the value 6.28~, equals to and is used to replace 2pi, so it is not related to "Twice Euler's constant". --162.158.166.146 08:33, 31 December 2023 (UTC)
