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.
Almost 300 extrasolar planets have been discovered so far, with as many as 13 objects by the OGLE team: lead by Udalski, Kubiak, Szymanski, Pietrzynski. Also other Polish astronomers made notable planetary discoveries, namely Aleksander Wolszczan (the first ever extrasolar planets), Maciej Konacki (a planet in a triple star system), Andrzej Niedzielski (a planet around a red giant) or Krzysztof Gozdziewski (who, by means of theoretical calculations, found a fourth planet in a system where other observers had seen only three objects), Kozłowski, Pojmański.
(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.
