Conservapedia talk:Conservapedian mathematics
Constructivism, or why the controversy about proof by contradiction is actually real
The general idea is that objects whose existence has been proved by proof by contradiction cannot be exhibited, and thus such a way of constructing them is rejected by constructivist school of thoughts. In fact, constructivist maths, which focus on defining and constructing objects, can go as far as rejecting the axiom of excluded middle (in particular due to infinite sets). Constructivists are a minority among mathematicians, but they include many well respected mathematicians like Markov* or Bishop, and contributions made by constructivist mathematics are notable in a number of domains (in particular fundamental math, algebra, topology, logic and computer science). See also finitism or intuitionism (Brouwer, Godel, Kolmogorov, ...).
So all in all I cannot say if conservapedia understands what they are talking about, but the "controversy" definitely exists and the article should reflect that. To give an analogy, the Copenhagen interpretation of quantum physics is accepted by most physicists, but is still very controversial. For most people and in particular students it does not matter, and the differences are mostly a matter of philosophy, but it doesn't make the defender of other approaches (many world, pilot waves**, ...) wrong just because of it.

(**An interpretation that is surprisingly unknown by the general public and even physics students, considering it was championed amongst others by De Broglie, Bohm and Bell) — Unsigned, by: 184.108.40.206 / talk / contribs
Axe wielding time
I changed a d to an a in one word and apparently my edit has copy and pasted a whole chunk of other stuff. But I never highlighted anything, never copied anything and never pasted anything. Then a following "undo" action only removed some but not all of the previous change. What have I done?
Also how have I done it because if I could do whatever it was on purpose it might actually be pretty useful. I am now about to have one last try at undoing it all, then someone else can do it. Fonzie (talk) 20:54, 2 September 2014 (UTC)
- Six fucking edits. Look at the net change achieved with six edits. Fonzie (talk) 21:20, 2 September 2014 (UTC)

Twin prime conjecture
- In apparent preparation for this class, Andy did ask his brother Rogerimg (who is also a conservative fundamentalist, but has a Ph.D. in mathematics) whether he had a proof of the Twin Primes Conjecture. Roger replied, quite sensibly, that he believes it is true, but has no proof.
Communist maths and others demons
I could not contain the laughter with the part of the "Vietnamese communist mathematician". I wonder what Schlafly and friends would think if they find out that the Fields Medal has been given to Soviet and Chinese mathematicians. — Unsigned, by: 220.127.116.11 / talk
