Twin Primes in "Did You Know"
The item says "only 35 even numbers have been found that are not the sum of a pair of Twin Primes?". Shouldn't "a pair of Twin Primes" actually mean two primes which are twins? I'd like to rephrase this as as "only 35 even numbers have been found that are not the sum of two primes which are each in a Twin Prime pair?" I don't want to make the change myself in case I mess up something. Dingo1729 (talk) 04:31, 2 June 2010 (UTC)

 * more seriously it does not seem to be a proper DYK: it's not mentioned in the article at all that I can see, and instead has a link. It's the 28th and list in the list, and the one above it, the 27th, seems similarly out of place as it mentions a fact not in any article so is synthesis. So I've removed them - there's no particular reason to have 27 rather than 25. I'm sure more can be found that are proper DYKs as there seems to be a big gap in the archive. -- JohnBlackburne wordsdeeds 23:06, 15 June 2010 (UTC)

Problem
The Mathematics Portal appears bogus right now : apparently asian characters have replaced the table of Mathematics topics

The three group isomorphims theorems
Hello,

I've been reading on group theory. If you look at |this pdf you will see three theorems regarding isomorphims, starting page 21 (1.43, 1.45, 1.46, and 1.47). Does Wikipedia have articles on those? If not, I will start them, if it does, could you kindly point me to them? Tony (talk) 02:58, 13 October 2010 (UTC)
 * I found this but it doesn't refer to the "correspondence theorem." Tony (talk) 03:16, 13 October 2010 (UTC)
 * We call it the lattice theorem. Algebraist 23:40, 14 October 2010 (UTC)

(Im)possibility of filling a Klein bottle?
I am looking for a reference to show that a Klein bottle cannot be filled with a liquid, and that the liquid will stay "inside" the bottle. Any hints? --Eptalon (talk) 16:38, 2 December 2010 (UTC)

In the christmas spirit...
It would be cool if the picture of the month was a wada basin made from christmas ornaments like this one: http://www.andamooka.org/~dsweet/Spheres/mucho.jpeg

The article on wada basins sucks though. —Preceding unsigned comment added by 128.244.9.9 (talk) 16:29, 10 December 2010 (UTC)
