Great heroes of other countries that we know

It has to do with everything. My point being Poland was/is/will not (be) an environment propice for intellectual development. In fact, the origin of a person is quite irrelevent, it is the influence of society on that person that truly matters. Which society influenced Copernicus the most for his intellectual enlightenment?  I would say Italy and Germany and certainly not poland. In poland, he simply learned the basics. He had to move overseas for more. Frauenburg although in Poland was actually peopled by Germans in those days.

Einstein was german by the way, of Jewish faith. That's why his name was Einstein not Ben Gurion

Actually soon after Copernicu's death Commonwealth of Poland and Lithuania became way more enlighted country than France. When in France even between arictocracy the art of writting was rare and people were murdering one each other in great numbers for religious reasons, in Poland our political philosophers were writting treaties about democracy and religious tollerance (in the 16th century for most of French it were unknown words), large part of population was speaking latin (foreign travellers were even writting that in Poland is more latinists than in Latium), people were saying and printing whatever they wanted without being afraid of death. In 1573 AD catholics and protestants signed act of Confederation of Warsaw (they saw what happend in France during St. Bartholomew's Day Massacre) and even forced newly elected French on Polish throne to sign it (he didnt want to accept it so was simply forced to do it, just like more fanatic catholic bishops who were much less fanatic than this French). So before you start talking about intelectual enviroment in other countries first look into your own which for long was pretty backward.
