Actually that is false, most girls in engineering / science are Russian or from former Soviet Union. Russia doesn't have the "gender imbalance" problem. In Soviet Union all were equal you know. This puzzles the western feminist - how supposedly backward system could have no gender issues at all? First Soviet woman to space waited months to follow the first Soviet man. First American woman waited decades... Even with that level of equality in Russia its not 50% - 50% - they are just fine with more men in math.
