Uhh... I make an active effort to educate myself? Like I said, I'm a historian. I was chiefly interested in science among other subjects during my schooling but I don't retain all the knowledge. Three major things to attribute to it, I guess, is 1) I have the internet, and 2) I have much more world experience than most people, and 3) Just general differences in schooling and education from country-to-country. The German education system isn't the best in the world, but it's far from the worst.
