They're actually quite accurate. I've used these in calculations, and they seem to give close enough answers.

:: This explanation covers 42 adequately, and would probably be made slightly worse if such information were added. The very widely known cultural reference is to Adams's interpretation, not Dodgson's original obsession. Adding it would be akin to introducing the MPLM into the explanation for the hijacking of Renaissance artists' names by the TMNT. I definitely concede that it does not cover 42 exhaustively, but I think it can be considered complete and in working order without such an addition. If it really irks you, be bold and add it! --[[User:Quicksilver|Quicksilver]] ([[User talk:Quicksilver|talk]]) 00:37, 30 August 2013 (UTC) | :: This explanation covers 42 adequately, and would probably be made slightly worse if such information were added.

"sqrt(2) is not even algebraic in the quotient field of Z[pi]" is not correct. Q is part of the quotient field of Z[pi] and sqrt(2) is algebraic of it. The needed facts are that pi is not algebraic, but the formula implies it is in Q(sqrt(2)). --DrMath 06:47, 7 September 2013 (UTC) | "sqrt(2) is not even algebraic in the quotient field of Z[pi]" is not correct.

: No big mystery around here. Just a beautiful formula :) I think there are similar formulas with cosines and even integers. I'll post them here if I have time.

In first explanation it says: "99^8 and 69^8 are sexual references". 69 I understand, but what would 99 refer too? | In first explanation it says: "99^8 and 69^8 are sexual references". 69 I understand, but what would 99 refer too? | ||
