Latest comment: Ahhh... A better measure is Per Capita (per 1 Million inhabitants) Nobels... US 1.045, UK 1.886, Germany 1.251, France 0.871, Sweden 2.993... This must have been a post by an American... just because the population is so large, cannot use that bulk to claim that core values are high, per capita is a much better measure! Maybe we should start posting 'stupid frogs? "
