I'm not really intending to discuss anything with this guy (Harry, Delphi or whoever he is) but people bringing up "Copernicus" or saying that Polish science is crap due to WW2 made me to write a few lines on real problems of Polish science...
I know your intentions were good, but please stop apologizing. There is nothing to ashamed of. Your astronomy example is good, so let me expand a bit:
Scientists discover around 600 gravitational lensing events every year within the OGLE project, which positions them as world leaders in this field. The project, based at Warsaw University, uses a dedicated 1.3-metre telescope mounted in Las Campanas in Chile. The OGLE Web Site is available at ogle.astrouw.edu.pl.
(There is an OGLE thread somewhere on PF, which I started long ago)
Personally, I was trying to keep my contribution to this thread at reasonably low profile - mostly responding to direct attacks from trolls, or expanding on some cases. But unfortunately this cannot be handled this way, because everybody has their own tactics: ranging from complete disregard of trolls, to apologizing, to giving trivial examples.
