I have spent some time on solving some of the quizzes on Project Euler lately. It’s basically about solving math problems – but they are all pretty tricky and special tools may be required. The website also have detailed overview of where people are from, most popular math tools and so on.

I figured I should make a more «fair» list of the country statistic, and here it is – Project Euler users per population. Population sizes are from Wikipedia. Total number of Project Euler users is at the moment 62318.

(All ratios are multiplied by 1000 to ease the reading .. and only countries with population > 10000 are accounted)
