Winning something like the IMO is mostly about the system of education and selection. Some countries value this sort of thing; others do not. Just like in SC, it's about how and what you train.
Hmm, it seems to be your 1014th post. Did you know that if you have a bunch of Russian market squares with directed roads connecting each square, such that each square has exactly two roads leading out of it, you can split the cities into 1014 districts such that all edges connecting two distinct districts go the same way?

All of the top US math people play SC. We actually faced off against the South Korean team last year, and beat them :D

where is this hosted? if its hosted in korea this year it would explain the disqualification

Are in you grad school for math? Even for math majors these problems can be quite hard. Just look at the scores of the putnam which is mostly taken by math ppl. The scores are really low even though many of the problems would be considered easier than imo ones.
Yeah, I looked at the putnam and it seemed a lot easier, but then again you have a lot less time on that one. But then I have taught linear algebra and the calculus sequence so I know just about everything from those courses, so it might just be me.

It was hosted in Kazakhstan this year. They were disqualified because the leaders, the day before the exam, gave the north korean students notecards on ideas that were used in the problems.
I've also heard that someone from North Korea has been 18 for 3 years now, so that might also have been why. This isn't the second time that North Korea has been dq'd, the first time was in 1991 I think?

Astana, Kazakhstan. All team leaders know the questions in advance because they vote on them, and aren't supposed to tell their team. Apparently the North Koreans disregarded this.
Edit: beaten to it.

NK got DQ'd again? What a shame...
GO INSUNG!!!!!!!!!!! (yay 3rd place! nice job sir)

I have never heard of this competition and browsed their site a bit to learn about the rules, etc. But, I couldn't find any good information. After looking at the questions, do these guys get to use computers or calculators? If not.. then wow. The people that were able to solve these things must be geniuses.

No calculators, nothing to help you.
Just your brain and a pencil. Oh and a paper.
IMO doesn't stand for International Math Olympiad for nothing.

Yay USA 3rd this year! (Though by one point...) US's team this year has no seniors so hopefully we can get first next year?
If I recall correctly, last time US got first was the 1994 year when all six US team members received perfect scores. It's really hard to have all six team members give a solid performance (see the related problem of MIT frequently making poor choices for its Putnam team representatives even though it generally selects the people who did best in the previous year or have a very strong history of past performance).
This is a great thread, and props to Stryker for getting me into Teamliquid back in undergrad when we were organizing HMMT.

Who spread Starcraft to MOP? I'd like to think I had at least a little bit to do with it

I (and supernovamaniac) actually know In Sung Na on the USA IMO team.
He goes to our school's math team 
EDIT: Also, Ukraine and Syria are clearly the only non-sexist countries (actually just Ukraine, Syria is the wrong kind of sexist though)

This brings back memory. I have two classmates who won silver and bronze medals for Vietnam team back in 2005.
And to explain why team China, Russia or US are good, you need to take into account the selection round before coming to IMO. (Check out this book:
http://www.google.com/search?q=china mathematic olympiad)
Even in Vietnam, the last round to select the team is more difficult than the IMO itself.

What grade level is this?

You never show up anymore. Statement above is invalid
Also, isn't this like the 3rd time NK has been DQ'd from the competition? And what's this year's reason?

Haha, US and China even make them go to math camp beforehand!
The Chinese contestants go through a camp, which lasts from March 16 to April 2.[14] In others, such as the USA, possible participants go through a series of easier standalone competitions that gradually increase in difficulty. In the case of the USA, the tests include the American Mathematics Competitions, the American Invitational Mathematics Examination, and the United States of America Mathematical Olympiad, each of which is a competition in its own right. For high scorers on the final competition for the team selection, there also is a summer camp, like that of China.

holy crap, that chinese guy got 100% on every question...

*communism killing your family joke*
Haha yeah 100% on each one zeesh that kid must be amazing in math hopefully he's not like a guy i know who is great at math horrible at everything else esp seap
found this little rule
Contestants must be under the age of 20 and must not be registered at any tertiary institution.
Well i see why some countries didn't do better, there are quite a few kids i am aware of that take community college at the age of like 13 and goes into a big school like MIT or Standford when they are a bit older 16 18 etc.

We weren't allowed to use calculators for the exams back home, so yeah. We had to learn the exact way of doing it on paper.
