(my post to Seanus was very personal)
It was actually polish invention(Stanisław Ulam), kerosene Lamp (£ukasiewicz)
I don't know if this names stick to this discussion :) with Russians.
Anyway truth should be said:
Both have done a lot for Poland. Stanisław Ulam was great Pole with Jewish roots. £ukasiewicz was great Pole with Armenian roots.
Armenians are one of my favourite ethnic groups in our history.
There was Polish saying that Greek can be only ripped off by Jew and Jew can be only ripped off by Armenian. (in trade).
Most of Poles with Arenian roots are now Ukrianians. Still some are present in our country.
