Congratulations to Ukraine and Bosnia-Herzegovina for being the only countries to send gender-balanced teams of three boys and three girls.

Are you implying that it would be good if the ones sent were based on a gender balance rather than being chosen on their math ability?

He might be suggesting that Ukraine and Bosnia-Herzegovina are to be lauded for having an educational system that doesn't end up leaving half of the population behind.

Intentionally uncharitable interpretation. More likely that the other teams (and the systems backing them) privileged guys, instead of educating and choosing on math ability.

It might be. What if there's a psychological barrier in place in a given society where a given group of people are repeatedly told either directly or implicitly through societal conventions inherited from previous centuries that they don't have the gift for science or maths in particular. In such a context, it would actually be beneficial to send "balanced teams" to such competitions so that it gives a mental boost (in the form of a symbol/token/role model that acts as a vessel) to perfectly capable people that just started with the handicap of being say "a woman", "a black" or "a redneck".

As such, reasoning in terms of "ability" is fundamentally flawed because "skills" are never innate, they're the result of a lot of work and positive circumstances in a given field and starting with a handicap from the get go just makes it so much harder that it's absolutely not a level ground.

Astonishing performance (3rd place) by North Korea with pop. around 25m. Not sure what incentives were in place for the contestants.

North Korea was caught cheating twice, and is the only country to have been caught cheating at the IMOs so far, so I would take their ranking with a grain of salt. [0] https://en.wikipedia.org/wiki/List_of_International_Mathemat...

How does one cheat at a test of this sort?

I looked a bit at the gender distribution for the gold and silver medalists, I would guess only 1 in 10-20 is a girl, most seemed to be from the eastern bloc countries.

I can't believe the audacity of Po-Shen Loh to send a team exclusively of boys to the IMO. When you have to select 6 team members how can you NOT select at least 1 female? This flies in the face of all the outreach work people have been doing to get more girls into STEM, and this victory will only discourage them. It appears the top 3 teams are all 100% boys.

I'm delighted that this is currently the top comment here. It shows we are clearly concerned with the right issues. I hope from now on all national teams participating in international competitions will be gender balanced. In order to remedy this situation we need:

   1) A Twitter mob
   2) An email campaign addressed Po-Shen to not repeat this and discredit his work and efforts. 
   3) A post of the team's picture to the popular twitter/tumblr account which shames all male conferences and gatherings 
   4) An email campaign addressed to IMO to implement rules that all teams should be gender balanced.
   5) A solution to Poe's law.

I hope not. When I did math Olympiads (including the IMO) I was presented with a false dichotomy of pure math or finance. This is really unfortunate because finance in general does not use very deep math. A tiny number of people might use SDEs but by now the techniques are standard and boring anyway. Furthermore, even mainstream economists doubt that this sort of finance has positive externalities. The amount of reso…

As someone who neglected statistics as a student ( topology was a lot funner) , would you have any recommendations for self-learning tools for statistics?

I would suggest "elements of statistical learning". If possible I would also try to study some econometrics which gives unparalleled insight into the correlation vs causation issue. You can think of econometrics as a branch of statistics that remained separate from the mainstream for historical reasons.

I assume most countries picked the best candidates for their teams, as mathematical aptitude is relatively easy to quantify. If it wasn't the competition would have no meaning. Congratulating Ukraine and Bosnia for this like it's some heroic sacrifice is odd. These girls were the best choice for their teams so they were picked. I don't see much more to it than that.

Team leaders know the question in advance. They are seperated from the team, but if they want to communicate they can.

Edit: have a read of this page. It shows that marking is not just a case of comparing the answer papers with a pre-prepared answer script. There is discussion and debate involved. http://www.imo-register.org.uk/2010-report.html

> Problem 4 was the second geometry problem, and so I led. We agreed four 7s straight away. The disputes were that I wanted a 7 for Luke Betts, and the co-ordinators were only offering 3 because they thought that there was a hole in his argument. On the other hand, they wanted to give Andrew Carlotti a 7 but I was only prepared to take 3. I explained to them the weakness in Carlotti’s argument, and they looked a little surprised. I asked them about the alleged weakness in Betts’s script, and I couldn’t understand what they were worried about. I suggested an overnight adjournment so that we could both make detailed preparations, and we met again the next day.
