Just a few pictures about the Institute of Mathematics.
Here I am outside the main door. All buildings with red signs like that are something official.
This is the view from my office window. You can see the The Palace of Culture and Science (Pałac Kultury i Nauki). It is the tallest building in Poland and can be seen from almost everywhere in Warsaw. It was a gift from the Soviet Union to the people of Poland.
I am based in the Stefan Banach International Mathematical Center, which is part of IMPAN. So here I am having a discussion about mathematics with Banach. He is a great listener, but offered no resolution to my problem.
