There is one Pole in Chicago who has given the world a stage where trolls can congregate.
haha, that one is good! :)
Just in a nutshell I found a site with 8 break-through inventions by Poles:
1. mine detector
2. movie projector (pleograf
invented allegedly a year before Lumiere's invention)
3. bulletproof vest
5. holography (additionally the same guy made a prototype of a tv set called electroscope
7. delta type wing
8. paraffin lamp (and first raffinery and petroleum mine)
Probably there are many more but I have no time to look for it.
